Plasticizing & Injection System
The plasticizing and injection unit are optimized by German technical consultants.
Screw speeds down before plasticizing over, injection piston is easy to be disassembled.
3 separate injection zones with pressure and speed adjustable, 3 dwell zones with pressure and speed adjustable.
Finite element stress analysis for all key parts ensures the max. rigidity of the parts.
3 separate clamping zones with pressure and speed adjustable; low pressure and high pressure adjustable protection device; multi-degassing motion setting, precise clamping stroke.
Electric and Hydraulic Control System
Specialized industrial computer and software control; all electric and electronic components are internationally famous brands.
Original German proportional flow rate valve, pressure valve, and direction valve guarantee the machine with smooth movement, no inner leakage, no wrong movement.
High quality oil pipe, connector, world famous sealing parts, endurable, and without outer leakage.
Temperature Control System
Advanced close-loop temperature control method guarantees the temperature precision +-1.
Non-evenly distributed heating power for upper and lower heating plate, improves the mould cavity temperature evenness.
Separate heat transfer oil system for plasticizing barrel and injection barrel to realize different temperature control and ensures precise temperature control.
