Introduction to Plastic Profile Mold Information:

Plastic profile molds are the core part of extrusion production lines, and their technical status directly affects the stability of extrusion production, the quality of extruded products, extrusion production efficiency, and the service life of the molds themselves. Proper use and maintenance are very important.

Extrusion molds, especially when the extruded material is modified polyvinyl chloride, are generally made of materials such as stainless steel and quenched and tempered to 24 | | RC or above to meet their service life.

The working surfaces of mouth molds, shaping molds, and their parts should be smooth and free from defects such as bumps, scratches, burrs, attachments, and rust. The surface roughness Ra should be less than or equal to; =0.02μm。

The flow channel system of the die head should be smooth along the direction of the melt flow, avoiding sudden changes in cross-section and stagnant areas as much as possible.
