Is there a difference between die saving and die polishing?

Die saving refers to die polishing, and there is no difference between them.

Mould polishing is a process of polishing the surface of mould cavity with oilstone, sandpaper, polishing paste and wool wheel to make the working surface of mould bright as a mirror, which is called mould polishing.

Mold polishing has two purposes:

One is to increase the smoothness of the mold, so that the surface of the products produced by the mold is smooth, beautiful and beautiful.

The other is that the mold can be easily demoulded, so that the plastic will not stick to the mold and will not fall off.

Extended data

Polishing is a very important process in the mold making process. With the increasing application of plastic products, the requirements for the appearance quality of plastic products are getting higher and higher, so the surface polishing quality of plastic mold cavity should be improved accordingly, especially for the mold with mirror surface and high gloss surface, the requirements for mold surface roughness are higher, so the requirements for polishing are higher.

Polishing can not only improve the aesthetics of the workpiece, but also improve the corrosion resistance and wear resistance of the material surface, and also facilitate the subsequent injection processing, such as making plastic products easy to demould and reducing the production injection cycle.

Mould polishing is a polishing method to remove the convex part after polishing by cutting and plastic deformation of the material surface, and obtain a smooth surface. Generally, it is oilstone strips, wool wheels, sandpaper, etc. Both are adopted, and manual operation is the main method. For special parts such as the surface of rotating body, auxiliary tools such as turntable can be used, and ultra-precision grinding and polishing method can be used for those with high surface quality requirements.

Ultra-precision grinding and polishing is a kind of special grinding tool, which is pressed tightly on the machined surface of the workpiece in grinding polishing solution containing abrasive and makes high-speed rotating motion. This technology can reach the surface roughness of Ra0.008μm, which is the highest among all kinds of polishing methods. This method is often used in optical lens molds.
