Servo Power-Saving Injection Molding Machine (KWS Series)
Overview: Characteristic ▪ Clamp•Injection•Control•Servo motor control•Technical Parameter•Application
Characteristic:
» Linear guide for injection carriage could lower the wear and tear, and make the injection control precise and stable. (Optional)
» T slot mould platen
» Apply international famous brand electric & hydraulic components.
» The injection base is modularized and could choose different matching type in accordance with injection volume.
» Smooth the mold opening speed curve design, and add the speed command to reduce the machine vibration.
» It has excellent precision control with the weight error of finished product is about 0.7% to 0.4%.
» Adopted servo power-saving system which could reduce the energy consumption 40%- 70%.
Clamp:
» Hydraulic (optional), mechanical and electric triple inter-locked safety device, mould close is not realized when open any one of the safety door.
» Low pressure mould protection device, protect mould from damage due to any foreign objects.
» Use hydraulic ejector pin to adjust traverse, eject forward and backward pressure & speed, multi action available.
» Use high precise linear transducer to inspect position, multi-zone control mould opening stroke speed and position, accurately positioned.
» Strengthen moving platen wear resistance guide way.
» Centralized lubrication system guarantee uniform oil supply for every lubrication dots.
Injection:
» Injection unit applies double guide post support, equip with fast and strong dual-cylinder balancing injection structure.
» Optimized design screw set, achieve excellent plasticizing effect.
» Using high quality nitride alloy or chrome coated screw and nitride barrel.
Control:
» TFT LCD color display
» Using high speed DSP processor, time control precision reaches
» High precise displacement transducer system, control precision
» Using fuzzy prediction technology, temperature control precision
» Multi input/ output interface, the interface function can be setting as demand.
» With output programmable function
» Support USB and network interface (optional)
» Parameter data lock protection, with auto save function in case accident power off
» Big data storage capability 
Servo motor control:
» Excellent energy saving as compared with the traditional fixed pump injection molding machine, it saves energy 20%-80% under the same working condition.
» Excellent injection molding stability
» Fast response
» Low noise and quiet operation
» Constant oil temperature
