When choosing cosmetics soft packaging hose production steel what is most important and the most decisive factor

Forming method can choose from two types of basic materials
1. Hot working tool steel, it can withstand the die casting, forging and extrusion of relatively high temperature.
2. Cold work tool steels, it is used for cutting and shearing, cold, cold extrusion molding, cold forging and powder extrusion forming.
plastic: some plastic produce corrosive by-products, such as PVC plastic, long shutdown caused by condensation, corrosive gas, acid, cooling/heating, water, or other factors, such as storage conditions also can produce corrosion, in these cases, it is recommended to use stainless steel material of cosmetics cosmetics packaging hose production die steel.
cosmetics cosmetics packaging hose production mold size: large size cosmetics cosmetics packaging hose production mold often use pre hardened steel, the hardened steel is often used in small size cosmetics cosmetics packaging hose production mold.
cosmetics cosmetics packaging hose production mold using the number of times: long-term use of cosmetics cosmetics packaging hose production mold should use high hardness steel, the hardness of 48 - 65HRC； Medium long time use cosmetics cosmetics packaging hose production mold should use hard steel, the hardness of 30 - 45HRC。
