Injection plastic mold polishing technology is very important for manufacturing plastic molding tools. It not only affects the quality of the mold but also plays a vital role in the quality of plastic parts.

In general, mold polishing serves two main purposes. First, it ensures easy and smooth demoulding of the plastic material. In addition, the smooth mold surface improves the aesthetics of the workpiece. It also helps to improve the wear and corrosion resistance of plastic surfaces. Often, effective plastic mold polishing techniques reduce injection cycle times. Mold polishing is a critical process in plastic manufacturing. So getting it right is crucial. The following tips will help you get the most out of your injection mold polishing process:

Before machining a new type of cavity, you must make sure to check the surface of the workpiece for any dirt. Cleaning with kerosene or another suitable solvent will ensure the proper functioning of the stone-cutting function.

Polishing a rough mold surface should start with the hardest part and then the easiest. Some dead corners can be difficult to sand. Therefore, the deep bottom part should be sanded before moving to the sides and flat surfaces.

Multi-component workpieces are best polished individually before polishing the assembled workpiece.

Use a whetstone to polish rough lines on large sides or flat workpieces. Check straight steel plates for undercuts and unevenness. Thus, you can ensure the easy release of parts and prevent any damage to them.

Applying sandpaper or saw blades to the edges of the contact surfaces will help achieve the desired protection.
