Die steel is mainly used to produce cold stamping die, hot forging die and die casting die steel. There are many kinds of materials used in the manufacture of mould, and the most widely used one is mould steel. In practice, the selection of section steel is generally divided into two situations, one is designated by the customer, the other is self selection. So, how to choose the die steel? What is the basis?
(1) Related to product requirements
There are some very high transparent products, such as optical lenses and glass lenses, which need steel with good polishing performance, such as S136. If the selection is wrong, the steel late mold will be cast into a mirror, and obvious material grain will be found, which can not be polished, so the mold production products do not meet the requirements.
(2) Related to the properties of plastic materials
For example, PVC plastics produce corrosive acid gas in the production process. If ordinary steel is used, the mould is easy to rust and corrode. Therefore, 2083, s136h and other corrosion-resistant steels should be selected.
(3) Related to die life
Even if the same brand of steel, the price will be different. Although the material quality with high price will be better, if the mold life does not need to be very high, you can choose relatively cheap steel.
How to select die steel reasonably is a complex system engineering, and the main work related to die manufacturing center link, die life and cost. We can select the die steel according to the above three preliminarily selected die steel, of course, we can also select the appropriate die steel according to the assignment function, function process, metallurgical quality, versatility and use requirements of die steel base.
The above is a detailed introduction to the material selection requirements of Shandong mold making. For more information, please click http://www.jnhjgs.cn
