compression molding Hot press forming moulds maker

The main process for forming thermoset and thermoplastic parts is thermoforming. What is compression hot press forming mold?

Compression molding is a method that uses pressure and heat to form large parts. Generally, the hot press forming mold needs to withstand a constant pressure and maintain it for a period of time to form a part. First, the material is preheated and placed in the heated mold cavity. Close the mold, apply pressure to fill the cavity with the material, and maintain the heat and pressure until the molded material solidifies. Commonly used heating for thermoforming molds includes electric heating, steam/hot water heating and oil heating. Since hot press molding uses heat and pressure to change material properties, it is suitable for molding complex, high-strength compounds for custom applications. Generally, these parts are lighter than metals and have an equal or greater strength-to-weight ratio.
