Advantages
- Power system can provide the amount of the energy which the servo motor injection molding machine needs in order to avoid energy loss.
- With new machine structure, HXM injection machinery is "the new break-though" of hydraulic injection molding machine
New Molding Clamping Structure
Adopting the internal rolling type five support crank web clamping structure, clamping part of servo motor injection molding machine is greatly optimized. In this structure, the cast connected-structure conrod and mould are reinforced by FEA (finite element analysis), which increases rigidity and precision of clamping part.
New Power Structure
The new power structure consists of servo motor, servo driver, pressure sensor, rotary encoder, gear pump and servo system.
