All Defu presses are manufactured in strict accordance with Japan’s JIS 6402 Grade-1 precision standard. Each machine features a high-rigidity frame design, welded with high-quality steel plates, shot blasted, and stress-relieved to ensure long-term dimensional stability and accuracy.

Defu offers hydraulic presses with pressures up to 10,000 tons. The entire hydraulic system uses cartridge valves, known for their simple structure, reliable operation, and leak-free performance—designed to support high-pressure, high-flow operations with excellent heat dissipation and minimal energy loss.

Yes. Our machines are engineered with high-rigidity frames using premium steel, stress-relieved for dimensional stability. Components such as the crankshaft, gear set, and connecting rods undergo hard oxidation and grinding treatments to ensure high durability and long-term precision. The optimized structure includes high-alloy steel, double crankshafts, and wide working centers with localized linkage support.
