Hydraulic System

 •Compact space saving toggle mechanism design

 •Finite Element Anaalysis ensures all platens key structural components for their maximun  service     life and best moulding results

 •Advanced stress analysis softwar are applied to design of tie bars and screw

 •Stable mould closing ,opening and adjustment

 •The ejector cylinder plate together with movable platen form a single  piece   of   casting   .This  improves rigidity of both ejector cylinder support and the platen

 •Increased ejector stroke and robustness of cylinder support specific for long hollow plastic parts

 •BOSCH-REXROTH Proportional pressure valve adjusts the range of pressure increase the control  precision

 •Adoption of valve pump that matches with proportional flow valve and pressure valve, improves the control accuracy

•Individual pressure valve adjusts the range of pressure increase the control precision

•New design of hydraulic circuit ,easy for maintenance

•Saving about 30%-50% of electricity compared with standard fixed vane pump

•Low heat occurred in hydraulic system and 30% cooling water quantity can be reduced

•Bypass filter device will ensure the hydraulic oil in a high cleanliness

Control System

•8" TFT color LCD panel (10.4" TFT Color LCD Panel is optional)

•Multi-languages display

•Four stages of injection and hold pressure phase (can expand up to ten stages )

•proportional Pressure/ FLow/Clamping Motion Control /Backpressure control characteristic curve can be adjustable on screen, so it can provide the best matching with the hydraulic proportional valve

•Automatic screen saver function to prolong the service life of display unit

•Automatic mould height adjustment function to adjust the position of toggle system according to the thickness of mould installled

•Screw rotation speed detection,operator can adjust the screw speed to achieve the best plasticization speed for product

•120 sets of mould data storage

•PID closed loop temperature control, temperature setting ranges between 0°C-399°C

•Clamping and injection position controlled by linear transducers

•High performance 16 bits processing CPU with scan cycle time lower than allows mort precision function

•Actual injection curve display and machine action simulation diagram are provide,helps to have better understanding on machine status and operation

•Welltec specific printer interface(optional)

•26(2A) digital output use smart power FET with short circuit and overload curremt protect, 56 optical isolation digital input points increase the reliability of control system

•High intensity LED indicators for digital input and digital output status are used, for eray observation even in dark environment

Injection Unit

•Creative design of injection unit

•High flexibility to match and change different diameter screws

•Diagonal layout of carriage cylinder to balance the supporting force(Above 90F2v)

•Screw and barrel are made of high quality new mate-rials,improved their working life

•Anti-wear bushes replaced by copper by bushes, which improve the lubrication result

•Four-stage injection speed and pressure setting

•Four-stage holding pressure and speed setting

•Two-stage meltrring speed and pressure arial
