Investment casting production process:

Investment casting is one of the manufacturing processes with a long history, can create parts with complex geometry and complex details. This investment casting process is beneficial to casting metal with high melting point temperature which can't be molded by gypsum or metal. Investment casting is popular because very intricate shapes with high accuracy can be made in this process.                                                                                   SIEG-HUAO is a professional steel investment casting supplier with advanced investment casting products and process.
