China JKS Upper Cylinder Frame Hydraulic Machine Suppliers - Ideal for Automotive, Jewelry, and Electric Appliance Factory Use
Product Features
The machine frame adopts high-quality steel and carbon dioxide gas protection welding, ensuring high rigidity and high compression strength.
The overall steel plate welding frame-type structure provides excellent stiffness, compressive strength, and strong resistance to off-load.
Features fast non-load running speed and quick pressure rise after mold closing (usually taking only a few seconds to reach rated pressure).
The work table moves from upper to lower positions, improving workpiece precision and ensuring operator safety when pressing sizable workpieces.
Pressure, stroke, and holding time can be easily adjusted to match specific pressing process requirements and adapt to different workpieces.
Equipped with a lower built-in, bottom-mounted oil tank/cylinder, making oil changes, system cleaning, and maintenance highly convenient.
