In mold factories, CNC machining centers are mainly used for processing key mold components such as mold cores and inserts, as well as copper pins. The quality of the mold core and inserts directly determines the quality of the formed part of the mold.

Factors affecting the demolding slope of injection molded products

1) The size of the demolding angle depends on the performance of the injection molded product, the geometric shape of the product, such as the height or depth of the product, wall thickness, and the surface condition of the mold cavity, such as surface roughness, processing patterns, etc.

2) Hard plastics have a larger draft angle than soft plastics;

3) The shape of the injection molded product is more complex, or plastic parts with more forming holes require a larger demolding angle;

4) If the height of the injection molded product is large and the hole is deep, a smaller demolding angle should be taken;

5) The wall thickness of injection molded products increases, the force of the inner hole wrapping the core is greater, and the draft angle should also be taken larger.
