About Investment Casting
Investment casting, also called lost wax casting, is an old metal forming process. Generally, using wax as casting mold, when the mold shell is dried, melt and remove the wax to fill with molten metal, then formed casting by cooling. For the processing of various metals and high-performance alloys, investment casting has the characteristics of high accuracy, multiple structures and complete components, and is especially suitable for processing large quantities of high-precision and high-strength metal castings.
- Excellent surface finish
- High size accuracy
- Could cast metal parts with very complex structure
- Almost suit for any metal
- No flash
Investment casting can be made from various materials such as stainless steel alloy, cast iron, brass, aluminum and carbon steel. It can be widely used in aerospace, power generation industry, fluid chemical, auto parts, marine equipment, engineering machine, heat treatment, food & medical equipment, energy, metallurgy and other industries.
