Influencing factors of plastic mold making

Influencing factors of plastic mold making

1. Parting surface

When the mold is closed, the concave mold and the convex mold cooperate with each other.

2. Structural parts

They are sliders, inclined tops, straight top blocks, etc. of complex molds, respectively.

3. Mold accuracy

Including card avoidance, precise positioning, guide posts, positioning pins, etc.

4. Pouring system

It is located between the nozzle of the injection molding machine and the cavity, and is composed of the main channel, the runner, the gate and the cold material cavity.

5. Others

Plastic shrinkage 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 molds and injection molds, the matching of process and structural parameters of the molding machine should also be considered.
