Foam Mould

According to different stamping materials designed by different stamping molds, basically through a number of steps of stamping to complete a product or semi-finished product operations.

Different steps require different shapes and specifications of tungsten carbide punches, which are designed to support the production of customized shaped punches for stamping molds. Cemented carbide shaped punches can be categorized according to the different shapes and uses:

1. Guide punch also called guide punch referred to as the guide punch, according to the needs of the press can have a variety of shapes, there are A-type B-type HB-type TAPP-type T**P-type and so on.

2. The mother punch needle also called mother punch referred to as mother punch, in the top of the punch there is a small protrusion, do not know what the name comes from, perhaps because of the protrusion at the top of the punch it. Letter punches can be divided into standard type A type JS ** type and other models.

3. There are also tooth extraction punching needles, checking tips, hexagonal punching needles, oval punching needles, molding punching needles, fan-shaped punches, shaped punching needles, high-speed steel punching needles, tungsten steel punching needles and so on.

Cemented carbide punches customized focus also designed to the precision and consistency of the product, its physical parameters are as follows:

1, CO content: 10%-20%.

2, Density g/cm3: 14.0-14.5.

3、Hardness: 87-92.0HRA.

4、Grain size: 0.6-1.2um.

5、Flexural strength: 4000MPa.

6、Modulus of elasticity GPa: 490.

7、Thermal expansion coefficient 10-6/0C: 5.4. 8、Carbide punches external dimensions specifications customized according to drawings, precision requirements to ± 0.002.
