Investment casting, which is also known lost wax casting or precision casting, refers to the formation of ceramic around the wax patterns to create a multi or single part mold to receive molten metal. This process utilizes an expendable injection molded wax pattern process to achieve complex forms with exceptional surface qualities. To create a mold, a wax pattern, or cluster of patterns, is dipped into ceramic material several times to build a thick shell. De-wax process is then followed by the shell dry process. The wax-less ceramic shell is then produced. Molten metal is then poured into the ceramic shell cavities or cluster, and once solid and cooled, the ceramic shell is broken off to reveal the final cast metal object. Precision investment castings can achieve exceptional accuracy for both small and large casting parts in a wide range of materials.
2- What Are The Advantages of Investment Casting?
✔ Excellent and smooth surface finish
✔ Tight dimensional tolerances.
✔ Complex and intricate shapes with design flexibility
✔ Capability to cast thin walls therefore a lighter casting component
✔ Wide selection of cast metals and alloys (ferrous and non-ferrous)
✔ Draft is not required in the molds design.
✔ Reduce the need for secondary machining.
✔ Low material waste.
