Excellent Molding Stability

  The servo driving system has its pressure and flow under closed loop control; and compared with traditional injection molders, its molding repetition precision is improved substantially.

Constant Oil Temperature

  The servo motor output hydraulic oil proportionately to prevent excessive heat.It can achieve substantial water saving even without cooling.

Rapid Response

  The servo driver features rapid response whose rapid starting time is improved by 50% compared with traditional injection.

Substantial Energy Saving

  Under the same conditions, it can save 20%-80% energy compared with traditional constant delivery pump injection molders.

High Performance Environmental Protection

  The complete machine features low operating noise, and even quieter during low-speed operation.
