Product Description

Clamping System:
High rigidity platen ensures even stress and less chance of deformation leading to high precision clamping.
Optimized tie bar design ensuring stable and speedy movement with less impact.
Lengthened distance between tie bar, mold thickness and opening stroke for more flexibility of mold use
Optimized lubrication system ensuring precision clamping and prolonging the life time of the clamping mechanism

Speedy differential clamping circuit satisfying special movement requirement.
Hydraulic driven gear mold adjustment for more speedy and safe mold change.
Low pressure mold protection
Choice of multi ejector mode
High precision imported linear transducer for more precise clamping and ejection position control.

Injection System:
Twin carriage cylinder ensures more even and stable injection (from K90VT-K200VT)
Fast response injection and sealing construction
Hopper slide guideway allowing more convenient and speedy material change
Nozzle temperature control by PID or percentage for easy processing
5 stage injection, 3 stage holding pressure& 3 stage plasticizing control satisfying different product requirements
Precise material temperature control ensuring product quality.

Adoption of imported Variable Displacement Pump:
Fast Speed: Adoption of high speed and high response variable displacement pump form Japan(Yuken/NACHI), Output capacity higher than normal piston pump of the same capacity by 15%-20%.
Power Savings: Can save power consumption by 25%-70% compared with normal piston pump.
Environment-friendly: Cooling water needed is 40%-60% lower than the machine installed with normal piston pump. High purified hydraulic oil can be used as long as five years.
Reliable: Long life of sealed parts and the overall hydraulic system because of the hydraulic oil.
Low noise disturbance: Compact hydraulic design enables more stable and peaceful machine operation.
