Liquid aluminum filled ring punch

The traditional cylinder punch has a low service life, which is easy to cause the metal liquid to pour backward, aggravate the barrel loss, and can not complete the production task well on the large-tonnage die-casting machine. It is difficult to use it to produce products with large volume, complex structure and thin wall, resulting in high scrap rate and rising production costs of enterprises.

The new type of ring punch, especially the ring punch above 130 in size, the expansion force of the ring and the pressure of aluminum liquid will make the ring close to the inner wall of the pressure chamber all the time, achieving a high sealing state, greatly improving the production qualification rate of complex structure and thin-walled products.
