(2) Tungsten steel hard alloy punches, such as tungsten steel punches, can be used to pass through longer and finer holes;
(3) The tungsten steel punch pin is also called the center. It is a conical metal rod assembled on the lathe or grinder to support the workpiece and make the workpiece rotate around it, but it is totally different from the tungsten steel punch of plastic mold accessories;
(4) Plastic mold tungsten steel punch pin can also be used in the mold, it can play a stable role, is called core pin.

1. Drawing, cutting
The raw materials that have passed the test are drawn into a
desired diameter size by a wire drawing machine, and then cut into
a rod-shaped punching pin blank of a fixed length.
2. Heat treatment
Before the heat treatment, the punching blank is firstly
straightened on the straightening platform with a dial gauge, and
then placed in a high-frequency electric furnace or a salt bath
furnace to be heated to 800-1300 degrees Celsius for 2 to 5
minutes. After oil quenching and hardening, the tip hardness of the
quenching heat treatment can reach Hv590-800. Then the low
temperature tempering treatment is carried out.
3. Grinding processing
The punching pin is clamped on the spring collet of the machine
tool, and the grinding forming process is separately performed
according to the angular requirements of the various needle bases
of the punching pin.
4. Polishing
Polishing is to clean the surface of the oil, rust, etc., and clean
the surface.
5. Inspection, storage
According to the required index, the qualified ones can be packed
into the warehouse.
BG has strict quality control system from the raw material incoming
to finished products outgoing. Our mould parts are guaranteed high
precision,high polished and long service life.
