Steel making plastic commonly used are molding. The hardness of the steel is the direct factor that determines the strength of the mold. Learn about the types of steel used for plastic molds.
What is steel making plastic ?
Steel for molds used in the production of molds. Due to the variety of molds used. So Fengyang also diversified the properties, range of materials used by the steel to meet the needs of customers. We manufacture steel according to the standards as follows:
DIN1.2083,1.4021,1.4028,1.2344,1.2343,1.2379,1.2312,1.23738,1.2085,1.2360,1.2581,1.2316,1.2085,1.2510,1.2367,17CrNiMo6,34CrNi3Mo, 36CrNiMo8, 718, 718V, WB36, …

How to choose the best plastic molds
Choosing high-strength steel to increase mold life means increasing the cost of molding. This means that cost increases lead to higher costs. Therefore, depending on the requirements, we should choose the type of steel suitable for plastic mold.
For molds that do not require high precision, molding materials should be S50C, S55C, and Nak80 … these materials are reasonably priced, easy to find and easy to work with. For high-precision molds, plastic material containing abrasive materials such as glass requires high-strength steels such as SKD11, ELMAX, SKH51 …
If you are designing molds that require high durability. In order to minimize the cost of molding, it is best to divide the mold into two parts and use two different types of steel. You can use low hardness materials, soft prices. The core of the mold should use materials with high hardness to meet the technical requirements that mold prices are greatly reduced.
Refer to some special types of steel at FENGYANG:
Types of steel difficult to find in the market, is the strength of the company. There are two types of steel: cold rolled steel and hot rolled steel.
