1. What kind of steel is suitable for making mirror molds
1. This kind of steel is widely used in molds with high strength and high hardness requirements.
Heat-resistant alloy steelHeat-resistant alloy steel refers to the steel grade that operates in harsh environments such as high temperature, high pressure, and strong corrosion, and its main characteristics are good tensile resistance, corrosion resistance, toughness, hardness and other properties.
2. The materials commonly used for mirror molds are SKD1SKD6NAK8S136 and so on. These steels have the hardness, toughness, and wear resistance to meet the manufacturing requirements of most molds. SKD11 is a cold work die steel with excellent machinability and grindability, and is often used in the manufacture of cutting dies, scraper dies, etc.
3. For molds with high standard requirements, S136 steel is recommended S136 steel is an internationally used mold steel, which has excellent wear resistance, corrosion resistance and toughness. S136 steel is more expensive to make, however, the price is worth the investment for manufacturers who have higher requirements for mold quality.
4. Stainless steel: Stainless steel has excellent corrosion resistance and high temperature strength, and is suitable for manufacturing molds working in humid or high temperature environments. Commonly used stainless steels are SUS42SUS440C and S136. These steels have high hardness and wear resistance, are able to resist corrosion and oxidation, and maintain the surface finish and accuracy of the mold.
5. High-quality steelHigh-quality steel usually has excellent mechanical properties and processing properties, not only high hardness, but also high wear resistance and thermal stability.
Therefore, high-quality steel is usually the best material for making mold mirrors.
6. S-STAR corrosion-resistant mirror plastic mold steel, the manufacturer brand of Daido Special Steel Co., Ltd. in Japan. The steel belongs to martensitic stainless steel, which has high corrosion resistance, high mirror polishing and small heat treatment deformation, and is used to make corrosion-resistant mirror precision plastic molds.
