Non-standard custom fastener carbon steel investment casting products

The greatest advantage of metal investment casting is its ability to significantly reduce machining work due to the high dimensional accuracy and excellent surface finish of investment cast parts. Only minimal machining allowances are needed in critical areas of the part, and some castings may even require only grinding or polishing, eliminating the need for machining altogether. As a result, investment casting can save a substantial amount of machining equipment and labor time while drastically reducing metal material consumption. However, the investment casting process is relatively complex, requiring strict control at every stage to avoid defects such as porosity, gas bubbles, and inclusions, which can lead to casting failures. Surface defects in investment castings can greatly impact their mechanical properties and service life. Therefore, it is essential to enhance process control and quality management during production to minimize defective products and ensure consistent quality.
