    Frequently Asked Questions (FAQ)

    What industries can benefit from using this hydraulic machine?
    This hydraulic machine is highly versatile and widely used in the metal processing industry (for cold/hot extrusion, forging, stamping, bending, and flanging), the plastic products industry (for hot pressing molding of basins, drums, toys, and pipes), and the powder metallurgy field (for pressing metal/ceramic powders into mechanical parts, electronic components, and cutting tools).
    Can the working pressure and stroke parameters be customized or adjusted?
    Yes. The working pressure, pressing speed, empty fast down, and deceleration stroke range can all be conveniently adjusted to meet specific process requirements.
    What are the design advantages of the four-column structure?
    The three-beam four-column structure is compact and robust. The four columns are made of high-strength alloy steel with a chrome-coated surface for excellent anti-wear performance. The four-column guidance ensures precise and stable movement of the movable cross beam.
    What ejection functions does the under-cylinder system support?
    The lower built-in cylinder provides efficient ejection processes, featuring multiple functions such as ejection, delay, and automatic return, which greatly simplifies the demoulding and removal of finished workpieces.
    What daily maintenance routines should be followed?
    Operators should inspect the equipment daily. This includes verifying that all connections are secure, checking that lubrication is adequate, ensuring there are no leaks in the hydraulic system, and promptly cleaning any dust or debris from the machine's surface.
    What is required for the regular maintenance of the hydraulic machine?
    Regular maintenance involves replacing the hydraulic oil periodically, cleaning the oil tank, checking the wear status of hydraulic components (such as oil pumps, cylinders, and valves), and replacing any worn parts to keep the system running normally and reliably.
