Product Description

Compliance requirements for presses vary across industries, and international customers often verify specific certifications based on the application scenario. For example, presses used in the automotive parts industry (used with forging presses and deep-drawing hydraulic presses) must comply with the IATF 16949 automotive quality management system, ensuring traceability throughout the equipment's production process (e.g., serial numbers of key components and maintenance records). Presses used in the aerospace parts industry must be certified under the AS9100 aerospace quality management system, meeting even higher standards for accuracy and stability (pressure control accuracy ≤±0.5% F.S., displacement accuracy ≤±0.02mm).

For customers in the EU market, presses are also required to provide "Energy Efficiency Certification" (compliant with the EU ECODESIGN Directive), achieving an energy efficiency rating of A and a noise level of ≤85dB (measured at 1 meter from the equipment during operation), complying with the limits for daily noise exposure under the EU Noise at Work Directive (2002/44/EC). For customers in the North American market, compliance with OSHA (U.S. Occupational Safety and Health Administration) safety requirements is required. Detailed equipment operating manuals (including safe operating procedures and risk warnings) must be provided, and operator training materials must comply with OSHA training standards to ensure safe operation.

Different forming equipment has significantly different pressure requirements. Automatic hydraulic cold forging presses must possess precise pressure regulation capabilities. For metal forging applications (such as automotive axle forging and hardware tool blank forming) using forging presses, international customers require presses with rated pressures ranging from 1,000 to 30,000 kN, with a pressure control accuracy of ≤±1% full scale (FS) to ensure stable pressure output during the forging process. For example, when forging an automotive axle, the press must maintain a constant pressure of 25,000 kN to prevent cracks caused by pressure fluctuations (the crack rate must be ≤0.1%).

For deep drawing applications (such as deep drawing of stainless steel sinks and forming automotive fuel tanks) using hydraulic deep drawing presses, customers are particularly concerned about "dynamic pressure response." The press is required to maintain a pressure regulation response time of ≤50ms during the deep drawing process (drawing speed 0.1-0.5m/s). The pressure can be adjusted in real time based on the drawing depth (for example, 5000kN at the beginning of the drawing, reducing to 3000kN at the end of the drawing). This prevents metal sheets from cracking due to excessive pressure or wrinkling due to insufficient pressure (the scrap rate must be ≤0.3%).

For powder metallurgy forming applications (such as automotive brake pad pressing and carbide tool forming) using powder compactors, customers have stringent requirements for pressure uniformity. The pressure distribution error of the press is required to be ≤±2% to ensure that the powder is evenly compressed in the mold (density deviation ≤±1%) and avoid defects such as delamination and looseness in the pressed parts (the qualified finished product rate must be ≥99.5%). At the same time, it supports multi-stage pressure settings (such as pre-pressure 500kN, main pressure 2000kN, holding pressure 1500kN), adapting to the "pre-pressure - main pressure - holding pressure" process of powder pressing to improve the density of the pressed parts (density ≥95%).
