Three-beam four-pillar structure, computer-optimized design, simple, economical, and practical. The hydraulic control system adopts a plug-in valve integrated system, which is reliable in operation, has a long service life, and has low hydraulic impact, reducing connecting pipelines and leakage points. The independent electrical control system is reliable in operation, intuitive in operation, and easy to maintain. It adopts centralized button control and has two operation modes: adjustment (jogging) and single-cycle (semi-automatic). It can realize two forming processes: fixed stroke and fixed pressure, and has functions such as delay. The working pressure and stroke can be adjusted within the specified range according to process requirements.
