The three beam and four column structure, optimized by computer design, is simple, economical, and practical. The hydraulic control system adopts a plug-in valve integrated system, which is reliable in action, has a long service life, small hydraulic impact, and reduces connecting pipelines and leakage points. Independent power control system, reliable operation, intuitive action, and easy maintenance. Adopting button centralized control, with two operation modes: adjustment (jog) and single operation (semi-automatic). It can achieve two molding processes of fixed distance and fixed pressure, and has performance such as delay. The work pressure and travel time can be adjusted within the specified range according to the process requirements.
