About Shell moulding die
Shell molding is a type of sand casting in which molding sand mixed with a thermosetting resin is applied to a heated mold (pattern) and hardened into a thin shell-like form. This method is characterized by higher dimensional accuracy and a superior cast surface compared to conventional sand casting. A typical processing method involves blowing resin-coated sand onto a preheated pattern, hardening it to form a shell, and then bonding these shells together to create a mold. It is widely used for manufacturing relatively complex shapes and thin-walled castings such as automotive parts (e.g., crankshafts, camshafts), industrial machinery parts, and piping components, achieving high productivity and stable quality.
