Cooling grill injection mold is a tool for producing plastic products; It is also a tool to give plastic products complete structure and precise size. Vehicle cooling grille tooling is also a processing method used in mass production of parts, which is mainly used in industrial field. The process of radiator grille mould is to inject the heated and melted material into the cooling grill injection mold cavity from high pressure, and after cooling and curing, the molded product is obtained; According to the cooling grill injection molding characteristics, it can be divided into thermosetting plastic mold and thermoplastic plastic mold.

1. About Radiator Grille Mould Processing
Cooling grill injection mold processing is a key process to produce plastic parts, and it is also a complicated process. It involves many links such as design, material selection, manufacturing, testing and maintenance.
The processing of vehicle cooling grille tooling is to add plastic into the cooling grill injection mold first, then the radiator grille mould rotates continuously along two vertical axes and heats it. Under the action of gravity and heat energy, the plastic in the vehicle cooling grille tooling is gradually and evenly coated, melted and adhered to the whole surface of the radiator grille mould cavity, cooling grill injection molded into the required shape, and cooled and shaped.
High-quality radiator grille mould can significantly improve production efficiency and product quality.
