Hydraulic press clamping

Mold clamping is divided into two steps. Before the male mold does not touch the molding material, it needs low pressure (1.5~3.0MPa) fast, which can shorten the cycle and avoid product changes; when the male mold contacts the molding material, start to slow down the closing speed , Switch to high pressure (15 ~ 3MPa) and slow speed, so as not to damage the inserts and allow the mold air to escape.
