Below are the introductions of a part of our customized products:

Electro-Permanent Magnetic Chuck EEPML Series
Used on Linear Guideway high precision or high accuracy oblong shape workpiece drilling, grinding machining…etc.


  • Structure of Electro-Permanent Magnetic Chuck, 1-3 seconds control fo power ON & OFF. No electric power supply required to keep the chuck ON.
  • EEPM Chucks can be connected and one controller can be control muti-EEPM Chucks.
  • Linear guideway or long strip workpieces can be fully clamped by EEPM Chucks for increasing grinding accuracy.
  • It could be used for long time and never get temperatures to affect the accuracy of workpieces.


  • Suitable for small, medium and large of linear guideway high precision or long strip workpieces. 
  • Using induction block can be increased the precision of linear guideway grinding.

Electro-Permanent Magnetic Chuck EEPM-PIM Series

Quick Mold Change Systems for Plastic Injection Machine


  • Electro-Permanent Magnetic system: 2~10 seconds control for power ON & OFF. No power supply required to keep the magnetic chuck on, Safety in case of power failure. Never get temperatures and deformation mold.
  • Magnetic force depends on the mold needs, with 3 sizes pole can choose.
  • Magnetic chuck is dual poles (N/S poles), no magnetize machine frame and equipment relative parts.
  • The clamping force is distributed consistently along the whole mold surface reduce product burs and increase mold duration.
  • Significantly reduce mold setting time up to 70%; shorten delivery time, increase efficiency and productivity.
  • Improve the strength and parallelism of machine movable/ stationary plate and machine frame.
  • Increase clamping area by 20%, perform clamping on all molds shapes, reduce burrs and the amount of mold maintenance.
  • Can be used with a working temperature up to 120℃, higher product safety.
  • No oil working environment, stable quality, applying for high working specification of germfree/dustfree.
