• Hybrid press
• In-plant design & fabrication
• Wood chip dehydrator

• Design　based on analysis

  In conventional structural analysis (two-dimensional frame calculation),
  the design is performed at the representative cross section to be analyzed,
  but FEM analysis makes it to be possible to model the frame structure and
  to be able to point out the stress conditions to inform it to designer.

  Control imagination

  

  ■Features

  ■Servo valve control realizes the precision ±0.05mm of slide stop position.

  ■Power saving compared to past press by adopting variable pump.

  ■Cushion is controlled seperately.

  ■Slide 2 ponit pallarel control is adoppted for long size eccentric forming.

  ■The total solution of press machine and automation is our proposal.

• In-plant design & fabrication

  ■Design

  Rationalization design　based on press frame F.E.M Analysis

  • 

  • 

  each oil pipe matches its original fabrication drawing.
  Pipe drawing makes it possible for quick change and on piping work out of manufacturer.
  Also, piping routine is designed with 3D-CAD, it is possible for the convenience of maintenance.

  • 

  • 

  Kawasaki original hydraulic control based on abandant know-how on over 2000 presses.

  • 

  ■Fabrication

  Strict quality and delivery management
  Steel blanking, welding, maching and assembly are performed in one plant to improve the realiability of our press machine.
