Snake lines – When the melt enters the mold cavity from the gate, it produces a jet effect and appears like a snake on the surface of the product, so it is called a serpentine flow line. 2. Wave lines – The flow of the melt in the mold cavity is not smooth, sometimes fast and sometimes slow.

Nettet11. nov. 2024 · Plastic injection mold polishing is a technique that helps to obtain smooth mold surfaces. It does this by removing the convex parts of the mold through plastic deformation and cutting. Generally, mold polishing techniques use wool wheels, whetstone strips, and sandpaper for manual polishing.
