Aluminum liquid filling type ring punch
Traditional cylindrical punches have a short lifespan and are prone to causing metal liquid backflow.
2023/02/11
The contact area between the steel ring and the inner wall of the melting cup is small, and the hardness of the copper ring is low
2020/08/03
The lifespan of traditional cylindrical punches is low, which easily causes metal liquid backflow
Beryllium bronze punch
Beryllium copper (beryllium bronze) has high strength, wear resistance, high temperature resistance
Solved the problems of ordinary punches being prone to cracking and wear caused by low pressure, gravity, and high pressure casting of non-ferrous metals in the country.
The steel punch (H13) has high hardenability, high toughness, and excellent resistance to thermal cracking.
Traditional pressure injection melting cups are prone to deformation and cracking during production and use, as well as issues such as corrosion pits at the bottom of the material inlet, conical inner holes, and scratches.
