1.2738 is used as mask mold
To cope with the problem of mask shortage, many mask factories extend the demand for mask mold. However, do you know which material is a suitable one for the mask mold manufacture? 1.2738 may be the ideal one.
S136 steel and the OT718H are also a suitable material for mask mold. which part do the 1.2738 works on the mask mold manufacture .It is used as the melt spray cloth mold. melt spray cloth is the core of the mask producing. So you shall choose the right steel material for it. As we know, 1.2738 is commonly used as a tool for steel and mold steel. Our Otai company has many 1.2738 plates of steel in storage, many mask manufacturers bought the 1.2738 and s136 from our company.
Why 1.2738 steel is used as mask mold?
1.2738 is based on P20 steel. Adding 0.9% to 1.2% Ni so that its toughness, plasticity, and corrosion resistance have been significantly improved. It is a widely used international plastic mold steel. Its comprehensive mechanical properties are good, quenched high, can make a larger cross-section of steel. It has a more uniform hardness, and polishing performance, mold surface finish is high.
When using the steel to manufacture the mold, the general first to adjust the treatment. the hardness of 28-35HRC (i.e. pre-hardened), and then by cold processing into a mold. It can be used directly. In this way, not only to ensure the use of mold performance but also to avoid heat treatment caused by mold deformation. Therefore, the steel species is suitable for the manufacture of large and medium-sized plastic molds.
The mask mold produced by Otai company has the good properties of cutting and embossing. the storage is limited, anyone wants it, please hurry up contact me.
