What Is The Production Process Of Plastic Bottle Caps?

Generally speaking, the production process is roughly divided into two types: the compression molding cover production process and the injection molding cover production process.

1. The production process of the compression molding cover

The suction machine sucks the mixed material into the barrel of the compression molding machine, and after heating the barrel to a semi-molten plasticizing state, it is quantitatively extruded into the mold cavity, and the upper and lower molds are clamped, compressed, cooled, shaped, and removed. Then, through cutting ring and padding, the production of compression molding cover is completed.

2. The production process of injection molding cover

The suction machine sucks the mixed material into the barrel of the injection molding machine, heats it in the barrel to a molten and plasticized state, injects it into the mold cavity, cools and molds in the cavity, and demolds it, and then goes through ring cutting and padding. , to complete the production of injection caps.
