Thermoplastics can be heated and cooled (or reshaped) multiple times. On the other hand, thermosetting materia... read more
Molding is a molding process in which the required material is placed in an open, heated mold cavity. The mold is then closed and pressure is applied to the mold with a large hydraulic press to make the material contact all areas of the mold. Presses are divided into mechanical and hydraulic types, ... read more
Compression molding process parameters The quality and performance of plastic parts is not only affected by the properties of plastic raw materials and the size of the mold structure, but also related to the formulation and control of molding process parameters. These are the three elements of moldi... read more
