What factors will affect the production process of plastic molds

Plastic mold is a combination mold used for compression molding, extrusion molding, injection molding, blow molding, and low foam molding. The coordinated changes of convex and concave molds and auxiliary forming systems can process a series of plastic parts with different shapes and sizes. What factors will affect the production process of Plastic Molds?

1. Parting surface
When the mold is closed, the concave mold and convex mold are mutually matched.

2. Structural components
They are sliders, slanted tops, and straight top blocks for complex molds.

3. Mold accuracy
Including card avoidance, precise positioning, guide pillars, positioning pins, etc.

4. Pouring system
Located between the injection molding machine nozzle and the mold cavity, it consists of a main flow channel, a splitter channel, a gate, and a cold material cavity.

5. Other
Plastic shrinkage rate and various factors that affect the dimensional accuracy of products, such as mold manufacturing and assembly errors, mold wear, etc. In addition, when designing compression and injection molds, the matching of process and structural parameters of the molding machine should also be considered.
