How accurate are Defu’s stamping presses?
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.
What is the maximum pressure of your hydraulic presses, and how stable is the pressure system?
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.
Can the press frame withstand long-term high-pressure operation?
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.
What are the advantages of your key components and manufacturing processes?
Defu uses premium international components such as Schneider relays (France), Mitsubishi/Siemens PLCs (Japan/Germany), Yuyi clutches (Italy), Siemens motors (Germany), and NSK/NTN bearings (Japan). Our production process includes advanced laser tracking, in-machine inspection, and hundreds of quality checks such as brake angle, tonnage, and rigidity testing to ensure every machine meets the highest quality standards.
What safety features are included, and are they reliable?
The automatic die height adjustment system offers 0.1 mm precision and is safe, convenient, and reliable. Our presses are equipped with high-sensitivity clutch and brake systems, dual solenoid valves, and overload protection devices to ensure safe and accurate slide operation.
How skilled is your after-sales team, and how fast is your response?
Defu offers direct and fast consultation channels for both equipment and technical support. We provide customized solutions, complete with machine configurations, performance specs, and professional quotations. Our sales engineers will guide you through model selection and ensure you make informed decisions.
Is the equipment easy to operate?
Yes. Our machines are user-friendly and come with operator training to ensure safe and efficient use.
