In our lives, digital products are our common products, and in the production of products, the use of digital product molds is also essential. In the appearance of the demand, the surface of the plastic mold cavity is often required to achieve the degree of mirror polishing, so that digital products have more practical performance.

Of course, in the production of optical lenses, lasers and other molds, the surface roughness is extremely high, and the polishing performance is also extremely high. Polishing not only increases the aesthetics of the workpiece, but also improves the corrosion resistance and wear resistance of the surface of the material.

Therefore, polishing is an important process for this type of mold. Different polishing techniques require different equipment. Complex polishing can polish complex shapes and can polish many workpieces at the same time to achieve high efficiency production.
