Electromagnetic Chuck By Xinpu Construction Machinery (Yantai) Co., Ltd

Product Features

Special Magnetic Circuit Design: Features a high air-gap magnetic flux density, aluminum wire coils, and wear-resistant, impact-resistant rolled high-manganese steel coil protection plates. The design ensures lightweight construction, low energy consumption, high lifting capacity, and long service life.
Advanced Insulation System: The insulation structure is optimized with vacuum drying and vacuum resin impregnation, enhancing both electrical and mechanical performance of the coils. The insulation material achieves a special-grade C heat resistance rating.
Control Flexibility: Typically operates with a constant voltage control system, but can be upgraded to a strong magnetic control system for even greater lifting capacity.
Simple & Reliable Structure: Suitable for various lifting equipment applications.
1. Suction Force
Electro-permanent Chuck: Delivers extremely strong holding force (16 kg/cmA ) with uniform and adjustable magnetic distribution, ideal for heavy-duty roughing and precision machining.
Standard Electromagnetic Chuck: Weaker and uneven magnetic force, unable to meet high-demand machining requirements.
2. Machining Precision
Electro-permanent Chuck: Maintains holding force without continuous power supply, eliminating heat generation during operation and preventing workpiece thermal deformation. The strong, uniform magnetic field ensures high precision even on protruding surfaces.
Standard Electromagnetic Chuck: Requires continuous power, leading to heat buildup, workpiece deformation, and reduced magnetic force over timea compromising precision.
3. Operational Performance
Electro-permanent Chuck: Continuous operation for over 20 hours/day without failure or maintenance.
Standard Electromagnetic Chuck: Loses holding force after ~6 months of use, requiring frequent repairs and part replacements.
4. Work Efficiency
Standard Electromagnetic Chuck: Requires extensive workpiece repositioning (40%-50% of total processing time), with frequent alignment errors and high scrap rates.
Electro-permanent Chuck: Features auto-assisted positioninga press a button for 0.3-second clamping/release, drastically improving productivity.
