Grey Cast Iron Semiconductor Accessories Industry knowledge
In semiconductor manufacturing, wafer handling is a critical part of the production process. The thin, delicate wafers must be handled with extreme care to avoid contamination, scratching, or damage. Grey cast iron components are used extensively in the frames and mechanical parts of wafer handling equipment, such as wafer transport systems, wafer bonding equipment, and wafer inspection tools. These components need to provide stable support while maintaining precise alignment during complex manufacturing processes. The high thermal conductivity of grey cast iron is particularly beneficial in this application, as it allows for efficient dissipation of heat generated during wafer processing. At Yancheng Longwan Machinery Co., Ltd., the company’s molding lines and advanced casting techniques ensure that every grey cast iron component produced for wafer handling systems meets the stringent tolerances required for such critical applications.

Automated systems and robotic arms have become increasingly vital in semiconductor fabrication plants, where precision, speed, and reliability are required for material handling, assembly, and packaging.
