tungsten steel produces precision tungsten steel back mold inserts for customization, PTJ tungsten steel processes precision tungsten steel back mold inserts, tungsten steel back mold punches, tungsten steel back mold cores and other tungsten steel inserts.
Tungsten steel back mold inserts are often used in precision stamping dies, mainly due to their good physical properties. Tungsten steel material itself has good and stable physical properties. Its wear resistance, corrosion resistance, high hardness, and high strength make it very widely used. It is the core working component under certain extreme working conditions, and the mechanical resistance of tungsten steel processing After grinding tungsten steel mold parts, the good performance and long service life of the mold inserts after grinding tungsten steel mold parts are effective ways to improve industrial production efficiency. The modern manufacturing industry’s demand for the use of high-performance mold products has become an important dependence on improving production efficiency and promoting economic development.
The size specification of the tungsten steel back mold insert is: Φ18*Φ15.33*Φ12.11*Φ12.07*Φ6.44*Φ6.4*64.85. There are many requirements for the outer diameter of the stage difference of the hanging platform, and the row and position tolerances are required to meet the fit.
PTJ tungsten steel processing precision custom-made tungsten steel back mold inserts, the used tungsten steel material parameters are as follows:
1. Grain size um: 0.6-1.2,
2. Cobalt content Co%: 8-15,
3. Density g/cm3: 14.45-14.8,
4. Hardness HRA: 87-92,
5. Bending strength Mpa: 3200-4500,
6. Young’s modulus Gpa: 570-620,
7. The dimensional accuracy of the finished inserts behind the tungsten steel requires a tolerance of ±0.002.
