'description' => '<div class="text-box">
<h2>Types of Wax:</h2>
<p>Investment casting is an oldest manufacturing. It is the proven technology to economically produce metal forms with low tolerance parts, complex geometries and superior surface finish, for achieving these it is very important to use superior waxes at every stages of casting.<br />It has been used in various forms from decades; earlier beeswax was used to form patterns necessary for the casting process. Today, more advanced waxes are used which are as follows,</p>
<ul>
<li>Filled Pattern waxes</li>
<li>Un-filled or Non-filled Pattern waxes</li>
<li>Runner waxes</li>
<li>Water-soluble waxes</li>
<li>Repair Waxes</li>
<li>Sticky waxes</li>
</ul>
<h2>Filled Pattern Waxes:</h2>

<h2>Water Soluble Waxes:</h2>
<p>Water Soluble waxes are widely used for making internal intricate cores of the wax patterns. These cores should be placed in wax pattern die. After wax pattern injection, these soluble cores should be dissolved in acid and water solution bath. Surface finish and productivity of these soluble cores is very good.<br />These waxes are leached before assembling of pattern on runners. There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>SOLCAST</li>
</ul>
<p><i>Note: It is an improvised version of regular soluble wax and is fortified with the solubility busters, these special type of accelerating molecules improves the solubility of the wax. This wax has proven better results when used with water mixed with mild acids.</i></p>
<h2>Repair Waxes:</h2>
<p>Repair waxes are paste type wax used to cover the surface defects of the wax patterns. This wax is widely used for repairing the surface defects of the wax pattern, like cavitations, flow lines and non-fills.<br />There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>REPAIR WAX (Colour: Red)</li>
</ul>
<h2>Sticky Waxes:</h2>
<p>This is a glue type wax. Sticky Wax provides a very strong joint which reduces the assembly time and makes the process hassle free.<br />There are different products which are highly efficient in this category, namely:</p>

<h2>Water Soluble Waxes:</h2>
<p>Water Soluble Waxes are widely used in investment casting industry and are used to achieve internal cavity in a casting and perfectly suited for making hollow items.</p>
<p><strong>General Properties</strong></p>
<ul>
<li>Water soluble wax is special product used for manufacturing of soluble cores to create critical internal shapes</li>
<li>Water soluble waxes can be used for any type of core configuration</li>
<li>Water soluble fibers contained formulations can increase strength and resistance to cracking</li>
</ul>
<p><strong>Advantages of water soluble waxes</strong></p>
<ul>
<li>Water soluble waxes are ease to inject like any other waxes</li>
<li>They have good surface finish</li>
<li>They have ability to produce many types and shapes of cores dimensions</li>
<li>They have excellent dimensional stability.</li>
<li>They can be easily leached from the patterns.</li>
</ul>
<p><strong>How to use water soluble waxes</strong><br />Water soluble waxes are different to other wax products. They are high in viscosity and have different melting characteristics. Here are some points below which will help you in using a water soluble wax-</p>
<h2>1. Melting of wax.</h2>
<ul>
<li>Melt the wax in a tank till it gets thick liquid</li>
<li>While melting the wax should be continuously aggregated or stirred using mixing tools</li>
<li>Entrap of air should be avoided while aggregating the wax</li>
</ul>
<h2>2. Producing of water soluble cores: Use of water soluble cores should be done with care</h2>
<ul>
<li>Care must be taken while filling injection tank and avoid air trap in tank while filling.</li>
<li>Injection temperature should be perfectly set to achieve good surface finish of cores</li>
<li>Die chilling is very important to increase productivity and avoid shrinkage of cores.</li>
<li>For better die release of the core, oil base die release agents or Greece can be used.</li>
<li>Injected Water-Soluble Cores must be stored properly avoiding contact with heat and Moisture.</li>
<li>Finished Water Soluble Cores can be used for Wax Pattern Production by placing the Soluble Core in to the tooling before injecting the wax.</li>
<li>Injected Wax Patterns should be allowed for complete solidification.</li>
<li>Water-soluble core should be leached out from the wax pattern with the help of mild acidic water. When the core material comes in contact with acid, dispersing of the core is started. To accelerate this process there should be light stirring of the acid bath. Also the acid should be replaced once it lost its strength.</li>
<li>After complete leaching of the core, wax patterns should be inspected properly and used for the production.</li>
</ul>
<h2>DISPOSAL:</h2>
<ul>
<li>Cores can be removed by immersion in a 10% solution of hydrochloric acid</li>
<li>Citric acid may be substituted but this will increase the wax removal time</li>
<li>A separate technical advice sheet is available on leaching of water soluble wax products</li>
<li>Wash patterns in clean water after removal from tank</li>
<li>To prevent deterioration of surface patterns should be stored in an airtight container</li>
<li>Any residues should be neutralized with a suitable material and then disposed of with normal foundry waste</li>

<h2>Filled and Unfilled Pattern Waxes:</h2>
<p>Wax blends have been used for pattern making in Investment Casting process from decades. Initially the wax blends were unfilled or straight Pattern Waxes and they are blend of Paraffin Wax, Micro Crystalline Wax, Natural Waxes like Carnauba and resins, These waxes tends to shrink while solidification due to a pure wax blend.<br />The shrinkage of the Unfilled Wax is depend on wax temperature, tooling temperature, wax solidification rate and wax injection pressure.<br />To avoid the shrinkage of the heavy or thick cross section of wax patterns, wax chills are generally used, Wax chills are placed in to the wax cavity before wax pattern injection. These chills should be injected previously of the wax patterns and after Wax Pattern Production, there are chances of occurring chill marks on the wax pattern surface.<br />Filled Pattern Waxes are having different types of filler materials mixed in the base to avoid surface shrinkage defect also to accelerate the solidification. <br />Filler materials are solid cross linked polymer are in free-flowing powder condition and mix homogeneously with the base pattern wax. <br />While solidification of the wax patterns, Filled Patterns solidify fast compared to Wax Patterns produced by Unfilled Pattern Wax because it remain in solid form in the molten wax. <br />Filler Waxes are preferred for high productivity, better consistency and improved pattern quality and it has limitations of recycling. <br />Below mentioned are comparison of unfilled and filled pattern waxes,</p>

<h2>Types of Wax:</h2>
<p>Investment casting is an oldest manufacturing. It is the proven technology to economically produce metal forms with low tolerance parts, complex geometries and superior surface finish, for achieving these it is very important to use superior waxes at every stages of casting.<br />It has been used in various forms from decades; earlier beeswax was used to form patterns necessary for the casting process. Today, more advanced waxes are used which are as follows,</p>
<ul>
<li>Filled Pattern waxes</li>
<li>Un-filled or Non-filled Pattern waxes</li>
<li>Runner waxes</li>
<li>Water-soluble waxes</li>
<li>Repair Waxes</li>
<li>Sticky waxes</li>
</ul>
<h2>Filled Pattern Waxes:</h2>

<h2>Water Soluble Waxes:</h2>
<p>Water Soluble waxes are widely used for making internal intricate cores of the wax patterns. These cores should be placed in wax pattern die. After wax pattern injection, these soluble cores should be dissolved in acid and water solution bath. Surface finish and productivity of these soluble cores is very good.<br />These waxes are leached before assembling of pattern on runners. There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>SOLCAST</li>
</ul>
<p><i>Note: It is an improvised version of regular soluble wax and is fortified with the solubility busters, these special type of accelerating molecules improves the solubility of the wax. This wax has proven better results when used with water mixed with mild acids.</i></p>
<h2>Repair Waxes:</h2>
<p>Repair waxes are paste type wax used to cover the surface defects of the wax patterns. This wax is widely used for repairing the surface defects of the wax pattern, like cavitations, flow lines and non-fills.<br />There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>REPAIR WAX (Colour: Red)</li>
</ul>
<h2>Sticky Waxes:</h2>
<p>This is a glue type wax. Sticky Wax provides a very strong joint which reduces the assembly time and makes the process hassle free.<br />There are different products which are highly efficient in this category, namely:</p>

<h2>Water Soluble Waxes:</h2>
<p>Water Soluble Waxes are widely used in investment casting industry and are used to achieve internal cavity in a casting and perfectly suited for making hollow items.</p>
<p><strong>General Properties</strong></p>
<ul>
<li>Water soluble wax is special product used for manufacturing of soluble cores to create critical internal shapes</li>
<li>Water soluble waxes can be used for any type of core configuration</li>
<li>Water soluble fibers contained formulations can increase strength and resistance to cracking</li>
</ul>
<p><strong>Advantages of water soluble waxes</strong></p>
<ul>
<li>Water soluble waxes are ease to inject like any other waxes</li>
<li>They have good surface finish</li>
<li>They have ability to produce many types and shapes of cores dimensions</li>
<li>They have excellent dimensional stability.</li>
<li>They can be easily leached from the patterns.</li>
</ul>
<p><strong>How to use water soluble waxes</strong><br />Water soluble waxes are different to other wax products. They are high in viscosity and have different melting characteristics. Here are some points below which will help you in using a water soluble wax-</p>
<h2>1. Melting of wax.</h2>
<ul>
<li>Melt the wax in a tank till it gets thick liquid</li>
<li>While melting the wax should be continuously aggregated or stirred using mixing tools</li>
<li>Entrap of air should be avoided while aggregating the wax</li>
</ul>
<h2>2. Producing of water soluble cores: Use of water soluble cores should be done with care</h2>
<ul>
<li>Care must be taken while filling injection tank and avoid air trap in tank while filling.</li>
<li>Injection temperature should be perfectly set to achieve good surface finish of cores</li>
<li>Die chilling is very important to increase productivity and avoid shrinkage of cores.</li>
<li>For better die release of the core, oil base die release agents or Greece can be used.</li>
<li>Injected Water-Soluble Cores must be stored properly avoiding contact with heat and Moisture.</li>
<li>Finished Water Soluble Cores can be used for Wax Pattern Production by placing the Soluble Core in to the tooling before injecting the wax.</li>
<li>Injected Wax Patterns should be allowed for complete solidification.</li>
<li>Water-soluble core should be leached out from the wax pattern with the help of mild acidic water. When the core material comes in contact with acid, dispersing of the core is started. To accelerate this process there should be light stirring of the acid bath. Also the acid should be replaced once it lost its strength.</li>
<li>After complete leaching of the core, wax patterns should be inspected properly and used for the production.</li>
</ul>
<h2>DISPOSAL:</h2>
<ul>
<li>Cores can be removed by immersion in a 10% solution of hydrochloric acid</li>
<li>Citric acid may be substituted but this will increase the wax removal time</li>
<li>A separate technical advice sheet is available on leaching of water soluble wax products</li>
<li>Wash patterns in clean water after removal from tank</li>
<li>To prevent deterioration of surface patterns should be stored in an airtight container</li>
<li>Any residues should be neutralized with a suitable material and then disposed of with normal foundry waste</li>

<h2>Filled and Unfilled Pattern Waxes:</h2>
<p>Wax blends have been used for pattern making in Investment Casting process from decades. Initially the wax blends were unfilled or straight Pattern Waxes and they are blend of Paraffin Wax, Micro Crystalline Wax, Natural Waxes like Carnauba and resins, These waxes tends to shrink while solidification due to a pure wax blend.<br />The shrinkage of the Unfilled Wax is depend on wax temperature, tooling temperature, wax solidification rate and wax injection pressure.<br />To avoid the shrinkage of the heavy or thick cross section of wax patterns, wax chills are generally used, Wax chills are placed in to the wax cavity before wax pattern injection. These chills should be injected previously of the wax patterns and after Wax Pattern Production, there are chances of occurring chill marks on the wax pattern surface.<br />Filled Pattern Waxes are having different types of filler materials mixed in the base to avoid surface shrinkage defect also to accelerate the solidification. <br />Filler materials are solid cross linked polymer are in free-flowing powder condition and mix homogeneously with the base pattern wax. <br />While solidification of the wax patterns, Filled Patterns solidify fast compared to Wax Patterns produced by Unfilled Pattern Wax because it remain in solid form in the molten wax. <br />Filler Waxes are preferred for high productivity, better consistency and improved pattern quality and it has limitations of recycling. <br />Below mentioned are comparison of unfilled and filled pattern waxes,</p>

<h2>Types of Wax:</h2>
<p>Investment casting is an oldest manufacturing. It is the proven technology to economically produce metal forms with low tolerance parts, complex geometries and superior surface finish, for achieving these it is very important to use superior waxes at every stages of casting.<br />It has been used in various forms from decades; earlier beeswax was used to form patterns necessary for the casting process. Today, more advanced waxes are used which are as follows,</p>
<ul>
<li>Filled Pattern waxes</li>
<li>Un-filled or Non-filled Pattern waxes</li>
<li>Runner waxes</li>
<li>Water-soluble waxes</li>
<li>Repair Waxes</li>
<li>Sticky waxes</li>
</ul>
<h2>Filled Pattern Waxes:</h2>
<p>Filled pattern waxes are having excellent flow properties and consistent dimensional stability with superior surface finish. <br />It is suitable for manual as well as automatic production system. It is designed for big to small wax pattern production, It makes special for wax pattern production of Aerospace Parts, Automobile Components, Valve and Impeller Components, General Engineering and other industries.<br />There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>Filled pattern wax FPWE.30 (Colour: Green)</li>
<li>Filled pattern wax FPW.E40 (Colour: Green)</li>
</ul>
<h2>Unfilled / Non – Filled Pattern Waxes:</h2>
<p>Unfilled pattern waxes are the blends used in filling even the most complex dies, producing sharply defined patterns. And they are used in automotive, golf club and hardware applications like gears, decorative castings.<br />This waxes have exceptional flow properties, hence the wax is suitable for critical and precision applications. It works perfectly on both manual and automatic production systems. Also it has dimensional consistency which makes this wax suitable for mass production.<br />Speciality of this wax is simplicity in recycling and sustaining physical properties after dewaxing, these waxes are widely used in automotive, golf club and hardware applications like gears, decorative castings and other industries.<br />There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>Non Filled pattern wax NFPW.B200 (Colour: Blue)</li>
<li>Non Filled pattern wax UPW-E145 (Colour : Green)</li>
</ul>
<p>Runner waxes have excellent mechanical strength, low viscosity and melting point which ease use in assembly of pattern wax.<br />While dewaxing lower melting helps runner melt first and drain out of the ceramic mould and passage for the thermal expansion of the Wax Patterns which results in cracks free moulds. It has Good operational Soldering strength for avoiding part broken while handling the assemblies and shells.<br />There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>Runner Waxes UVERCON (Colour: Olive Green)</li>
</ul>
<h2>Water Soluble Waxes:</h2>
<p>Water Soluble waxes are widely used for making internal intricate cores of the wax patterns. These cores should be placed in wax pattern die. After wax pattern injection, these soluble cores should be dissolved in acid and water solution bath. Surface finish and productivity of these soluble cores is very good.<br />These waxes are leached before assembling of pattern on runners. There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>SOLCAST</li>
</ul>
<p><i>Note: It is an improvised version of regular soluble wax and is fortified with the solubility busters, these special type of accelerating molecules improves the solubility of the wax. This wax has proven better results when used with water mixed with mild acids.</i></p>
<h2>Repair Waxes:</h2>
<p>Repair waxes are paste type wax used to cover the surface defects of the wax patterns. This wax is widely used for repairing the surface defects of the wax pattern, like cavitations, flow lines and non-fills.<br />There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>REPAIR WAX (Colour: Red)</li>
</ul>
<h2>Sticky Waxes:</h2>
<p>This is a glue type wax. Sticky Wax provides a very strong joint which reduces the assembly time and makes the process hassle free.<br />There are different products which are highly efficient in this category, namely:</p>
<ul>
<li>STICKY WAX (Colour: Pale Yellow)</li>

<h2>Water Soluble Waxes:</h2>
<p>Water Soluble Waxes are widely used in investment casting industry and are used to achieve internal cavity in a casting and perfectly suited for making hollow items.</p>
<p><strong>General Properties</strong></p>
<ul>
<li>Water soluble wax is special product used for manufacturing of soluble cores to create critical internal shapes</li>
<li>Water soluble waxes can be used for any type of core configuration</li>
<li>Water soluble fibers contained formulations can increase strength and resistance to cracking</li>
</ul>
<p><strong>Advantages of water soluble waxes</strong></p>
<ul>
<li>Water soluble waxes are ease to inject like any other waxes</li>
<li>They have good surface finish</li>
<li>They have ability to produce many types and shapes of cores dimensions</li>
<li>They have excellent dimensional stability.</li>
<li>They can be easily leached from the patterns.</li>
</ul>
<p><strong>How to use water soluble waxes</strong><br />Water soluble waxes are different to other wax products. They are high in viscosity and have different melting characteristics. Here are some points below which will help you in using a water soluble wax-</p>
<h2>1. Melting of wax.</h2>
<ul>
<li>Melt the wax in a tank till it gets thick liquid</li>
<li>While melting the wax should be continuously aggregated or stirred using mixing tools</li>
<li>Entrap of air should be avoided while aggregating the wax</li>
</ul>
<h2>2. Producing of water soluble cores: Use of water soluble cores should be done with care</h2>
<ul>
<li>Care must be taken while filling injection tank and avoid air trap in tank while filling.</li>
<li>Injection temperature should be perfectly set to achieve good surface finish of cores</li>
<li>Die chilling is very important to increase productivity and avoid shrinkage of cores.</li>
<li>For better die release of the core, oil base die release agents or Greece can be used.</li>
<li>Injected Water-Soluble Cores must be stored properly avoiding contact with heat and Moisture.</li>
<li>Finished Water Soluble Cores can be used for Wax Pattern Production by placing the Soluble Core in to the tooling before injecting the wax.</li>
<li>Injected Wax Patterns should be allowed for complete solidification.</li>
<li>Water-soluble core should be leached out from the wax pattern with the help of mild acidic water. When the core material comes in contact with acid, dispersing of the core is started. To accelerate this process there should be light stirring of the acid bath. Also the acid should be replaced once it lost its strength.</li>
<li>After complete leaching of the core, wax patterns should be inspected properly and used for the production.</li>
</ul>
<h2>DISPOSAL:</h2>
<ul>
<li>Cores can be removed by immersion in a 10% solution of hydrochloric acid</li>
<li>Citric acid may be substituted but this will increase the wax removal time</li>
<li>A separate technical advice sheet is available on leaching of water soluble wax products</li>
<li>Wash patterns in clean water after removal from tank</li>
<li>To prevent deterioration of surface patterns should be stored in an airtight container</li>
<li>Any residues should be neutralized with a suitable material and then disposed of with normal foundry waste</li>

<h2>Filled and Unfilled Pattern Waxes:</h2>
<p>Wax blends have been used for pattern making in Investment Casting process from decades. Initially the wax blends were unfilled or straight Pattern Waxes and they are blend of Paraffin Wax, Micro Crystalline Wax, Natural Waxes like Carnauba and resins, These waxes tends to shrink while solidification due to a pure wax blend.<br />The shrinkage of the Unfilled Wax is depend on wax temperature, tooling temperature, wax solidification rate and wax injection pressure.<br />To avoid the shrinkage of the heavy or thick cross section of wax patterns, wax chills are generally used, Wax chills are placed in to the wax cavity before wax pattern injection. These chills should be injected previously of the wax patterns and after Wax Pattern Production, there are chances of occurring chill marks on the wax pattern surface.<br />Filled Pattern Waxes are having different types of filler materials mixed in the base to avoid surface shrinkage defect also to accelerate the solidification. <br />Filler materials are solid cross linked polymer are in free-flowing powder condition and mix homogeneously with the base pattern wax. <br />While solidification of the wax patterns, Filled Patterns solidify fast compared to Wax Patterns produced by Unfilled Pattern Wax because it remain in solid form in the molten wax. <br />Filler Waxes are preferred for high productivity, better consistency and improved pattern quality and it has limitations of recycling. <br />Below mentioned are comparison of unfilled and filled pattern waxes,</p>

Measuring the Melting Point Of Waxes Used in Investment Casting
May 06, 2021
Measuring the Melting Point Of Waxes Used in Investment Casting
The melting point of wax is important to both the wax supplier and the investment casting foundry.
The melting point of wax is important to both the wax supplier and the investment casting foundry. Wax manufacturers run tests as a part of quality control and wax development; foundries run tests on incoming waxes to determine melting time injection temperature and autoclave. Various organizations have testing methods that are applicable to the investment casting industry such as ASTM1 {American Society for Testing Materials), and ICl2 (Investment Casting Institute). One problem that arises, however, is that melting point means different things to different people. The melting point is usual1y defined as the temperature at which a substance makes a transition from the solid or semisolid state to the liquid state. In the investment casting industry, there are other terms that are sometimes used synonymously, including congealing point, dropping point, drop melting point, and softening point. Each of these terms, however, has a very specific definition. The congealing point is defined by the ASTM D938 method as “the temperature at which molten petroleum wax, when allowed to cool under prescribed conditions, ceases to flow.” The dropping point is defined by ASTMD566 as “the temperature at which the wax passes from a solid to a liquid state.” The drop melting point is defined by AS”TM 0127 as “the temperature at which material becomes sufficiently fluid to drop from the thermometer.” and lastly, the softening point is defined by ASTM E_8 as “the temperature at which a disk of the sample held within a horizontal ring is forced downward a distance of 1 inch, under the weight of a steel ball as the sample IS heated at st> C (9t>F’) per minute:” The Investment Casting Institute’s Determination of a Softening Point has a similar definition with the exception that it specifies the heating rate of 4° F per minute. Compounding the problem of determining melting point is the fact that a wax can have many “melting points,” depending on which test method is used. For this reason, an experiment has been conducted to compare some of the different test methods currently available for determining melting points. Goals of the experiment were to determine which test gave the most reproducible results, which test methods were most applicable, and to compare the results of one test with those of another. Saffroshine is a 25-year young company, manufacturing Pattern Waxes for Investment Casting Industry. Inert and Stable compositions compatible with various production and dewaxing processes. Better dimensional consistency and consistency of the Pattern Waxes. We are an Indian Manufacturing Company supplying to various Investment Casting Foundries in India and Overseas.
