Is NAK80 good steel to make mirror polish mold

NAK80 is  good high polish and mirror gloss mold steel, it is very common used on mirror polish mould. 

In our daily life, there are a lot of plastic mold products, all of which are made of high-gloss surface, but the plastic mold has high light. Is there any special attention to the selection of materials? Plastic mold highlights can both make the product high-end and reduce the cost of the product.
However, when making molds, there must be requirements on the selection of materials. The choice of poor steel can not be achieved, the effect of high light, and the life of the mold will also have an impact. Generally, the plastic mold high light will choose NAK80 material,  NAK80 is pre-hardened mirror-finished mold steel, has been pre-hardened to HRC38-41 without heat treatment. The mirror finish is up to 12000-15000. Can be used for large plastic molds with large-area mirror polishing, such as: lamp molds, all kinds of transparent plastic products.because its material density is relatively high, it is very suitable for high light, and the high light energy can be as smooth as a mirror. There will be a lot of materials for the molds, but companies that are generally not proficient in plastic molds will generally have errors in the selection of materials. Generally, in selecting suppliers, we must first look at the scale and equipment of the factory, as well as the comprehensive factors of the company's overall experience.

More common plastic mirror steel that can be mirror polished.

1. S136-D, anti-corrosion and anti-rust, high mirror polished mold steel. Hardened and hardened to HRC48-52, mirror polished up to 18000. Can be used for anti-corrosion optical grade mirror polishing plastic molds, such as: PP, PVC plastic materials.
2. 2083, Saskatchewan 2083 is a high-Cr-containing stainless steel with a Cr content of up to 15 or more. It has excellent wear resistance.And polishing performance is good. After quenching, it is more wear resistant.
   Suitable for electrolytic etching, suitable for acid plastics and molds that require good polishing.Steel properties:Good acid resistance, good polishing, easy processing,Steel name:Plastic mold steel,Factory state: B210-245,
3. Sulfur-free 8407, wear-resistant long life, mirror polished plastic mold steel. Hardened and hardened to HRC48-52, mirror polished up to 12000-15000. It can be used in precision, long-life plastic molds with complex shapes.

Mirror polished steel, in addition to the three mold steels described above, there are many steel numbers, such as: S136, HPM38, S-STAR, M333, M300, 2083, 8418, 2344, SKD61, DAC, DHA1, 8433, LG... …and many more. Each steel mill has a different name for its own steel number, which is difficult to cover.
