Whether it's for aerospace, automotive, medical, or various other industries, this process offers unparalleled accuracy and quality. Here are the detailed and refined basic steps involved in the investment casting process, which can help you better understand how these remarkable components come to life.1. Wax Pattern CreationThe investment casting journey commences with the meticulous creation of wax patterns. Highly skilled artisans carefully inject premium wax material into precisely engineered aluminum molds. These molds are designed to replicate the exact shape and dimensions of the final product with remarkable precision. The resulting wax model serves as the fundamental blueprint and foundation for the entire subsequent casting process. It's crucial to note that the quality and accuracy of the wax pattern directly impact the final outcome of the metal component.2. AssemblyIn the assembly stage, the individually crafted wax patterns are meticulously and carefully attached to a central wax sprue. This assembly is commonly referred to as a pattern assembly or a wax tree. The central sprue plays an indispensable and pivotal role as it will act as the essential channel through which the molten metal will eventually flow, filling the intricately shaped cavities of the wax patterns. This step requires great attention to detail to ensure proper alignment and secure attachment of the wax patterns to the sprue.3. Shell BuildingOnce the pattern assembly is complete, it's time to embark on the transformative shell-building stage. In this complex and delicate step, the pattern assembly is repeatedly dipped into a high-quality ceramic slurry. Multiple layers of refractory materials are gradually applied, but it's of utmost importance to ensure that each layer is completely dry before adding the next one. This painstaking process results in the creation of a robust, durable, and thick ceramic shell that envelops the delicate wax patterns, providing the necessary structure and protection for the subsequent steps.4. DewaxingAfter the ceramic shell has been fully formed, the critical step of dewaxing comes into play. The entire assembly, now encased within the ceramic shell, is placed into a specialized furnace and subjected to high temperatures. This heating process causes the wax inside the ceramic shell to melt and drain out, which is why investment casting is also commonly known as "lost-wax casting." The end result is a hollow ceramic mold with precisely defined cavities that are an exact replica of the original wax patterns, ready to receive the molten metal.5. Burnout/PreheatingFollowing the dewaxing process, the ceramic mold undergoes a burnout stage, during which it is exposed to extremely high temperatures. This burnout process serves several important purposes. It ensures that any residual wax is completely removed from the mold, hardens the ceramic structure, and prepares the mold for the upcoming pouring process. Preheating the mold is essential as it helps the molten metal flow more smoothly and fill the cavities evenly, reducing the risk of defects. Once the preheating is complete, the mold is in the optimal condition to receive the molten metal.6. PouringThe pouring step is the core and most crucial part of the entire investment casting process. Molten metal, carefully selected to meet the specific metal grade requirements of the component, is meticulously poured into the preheated ceramic mold. The metal flows rapidly into the intricately shaped cavities, filling every corner and crevice of the mold. As the molten metal cools and solidifies within the mold, it takes on the exact shape and dimensions of the original wax patterns, bringing the desired metal component to life. Precise control of the pouring process is essential to ensure the quality and integrity of the final product.7. Shell RemovalOnce the metal has fully solidified, the ceramic shell that once protected the casting needs to be removed to reveal the final metal component. Vibratory methods are commonly used to break away the ceramic shell, carefully unveiling the intricately crafted metal casting hidden within. This step requires careful handling to avoid damaging the delicate metal part.8. Cut-offAfter the shell has been removed, the individual metal castings are separated from the central sprue using specialized saws or cutting tools. This separation process is carried out with precision to ensure a clean and accurate cut, leaving the metal component ready for further processing.9. FinishingThe final step in the investment casting process involves performing any necessary finishing operations to meet the specific requirements of the component. Depending on the application, various finishing techniques may be employed. For instance, heat treatment might be necessary to enhance the mechanical properties of the metal, such as its strength and hardness. CNC machining can be used to achieve more precise dimensions and tolerances. Shot blasting is often utilized to clean the surface and achieve a fine, smooth finish, while polishing can be done to obtain the desired bright and attractive surface appearance. Investment casting is a truly remarkable manufacturing process that combines skill, precision, and advanced techniques to produce high-quality metal components that meet the most demanding standards across a wide range of industries.Materials We Cast MaterialCarbon SteelDuctile IronAlloy SteelStainless SteelManganese SteelMaterial Grade/DesignationZG200-400ZG230-450ZG270-500ZG310-570ZG340-640Q235QT350-22LQT400-18QT400-18LQT450-10QT500-7QT600-3QT700-2QT800-2QT900-2QTD800-10QTD900-8QTD1050-6QTD1200-3QTD1400-1ZG20Mn, ZG30MnZG40Mn, ZG20Mn2ZG35CrMnSi, ZG40CrZG35CrMo, ZG42CrMoAH36,EH36,FH36Q420qE,Q500qE16MnDR09MnNiDRZGD410-620ZGD535-720ZGD650-830ZGD730-310ZGD840-1030ZGD1030-1240ZGD1240-145006Cr19Ni10022Cr19Ni1006Cr17Ni12Mo2022Cr17Ni12Mo206Cr18Ni12Mo2Cu2015Cr21Ni26Mo5Cu212Cr1330Cr1368Cr17022Cr1210Cr17019Cr19Mo2NbTi022Cr23Ni5Mo3N022Cr25Ni7Mo4N05Cr17Ni4Cu4Nb07Cr15Ni7Mo2ALZGMn13-1ZGMn13-2ZGMn13-3ZGMn13Cr2Q355BQ460C30Mn2Cr1040Mn18Cr3ZGMn18Cr2 StandardAISI - American Iron and Steel InstituteASTM - American Society for Testing and MaterialsDIN - Deutsches Institut für NormungBS - British StandardsANSI - American National Standards InstituteJIS - Japanese Industrial StandardsAFNOR - Association Fran?aise de NormalisationAS - Standards AustraliaASME - American Society of Mechanical EngineersEN--European NormGB--National Standard Chinese2014/68/UE (PED)NoteApart from the above materials, we can cast based on customers' specificationsPackaging & ShippingPackagingRust Prevention Treatment: The surface of the cast steel parts is sprayed or smeared with high-quality rust preventives to form a dense anti-rust film, effectively preventing rust during transportation and storage.Buffer Protection: For parts prone to bumps, buffer materials such as foam boards and sponges are used for wrapping to prevent collision damage during transportation.Outer Packaging: Small cast steel parts are packaged in sturdy wooden boxes, and the inside is filled with stuffing to ensure that there is no shaking during transportation; large cast steel parts are fixed with customized metal frames or wooden frames, and if necessary, container transportation is adopted to ensure transportation safety.ShippingLogistics Selection: We have established long-term cooperative relationships with several well-known logistics enterprises.
