Used plastic injection machines
Machine location: China
Machine packing: wooden case
PID temperature control enables accurate control of material pipe temperature
Alloy material with anti-wear and corrosion resistance can be selected for pipe screw
There are three kinds of screw for customers to choose, the screw length / diameter ratio is 20:1 (standard)
Double cylinder injection mechanism, made of high strength mihanna cast iron, strong and powerful
Six stage injection, six stage pressure maintaining and three stage feeding back pressure control
The injection system can be rotated to facilitate the maintenance of screw and tube
The screw can be released before or after feeding
It has the function of setting the error range of injection quantity and abnormal detection function, screw automatic release and automatic cleaning pipe function
It can save 10% – 20% electricity and reduce the ambient temperature of the workshop
Our used machines
Mold locking system:
This series of injection molding machines with crankshaft structure are used for plastic injection products with precise electronic and high firing rate
The formwork and large column are designed by CAE analysis, with strong rigidity and minimum deformation
Adjustable low-pressure mold protection device, accurate and high protection sensitivity, can avoid foreign body damage to the mold
The mould fixing hole, thimble hole and mould positioning ring on the template are all made according to international standards (EUROMAP, JISSPI)
It adopts inclined plate optical positioning ruler, which has long service life and fast switch, and is not easy to be damaged
The stroke, demoulding force, jacking speed and ejection speed can be adjusted by hydraulic pressure ejector, and the demoulding times can also be preset
Triple safety protection device for electric hydraulic machinery
Automatic mold adjustment system can achieve high and low pressure automatic setting of mold closing
Four movable safety doors with large visual range and easy maintenance
Hydraulic mechanical hardware system:
Under ideal conditions, it can save energy by 40% compared with variable displacement pump system and 70% compared with quantitative pump system, which can effectively save energy cost.
It adopts LCD full color screen microcomputer made in Taiwan, with a reaction speed of 2.0ms and excellent stability
The pump and valve parts imported from Japan are adopted, the reaction speed is as high as 20Hz and the service life is long
The screw material pipe group made in Taiwan can be customized according to the product requirements of customers
Oil seals made in Japan and Germany are used to ensure stable molding without oil leakage
The pressure of each molding stage and the back pressure of feeding can be read directly by the pressure gauge
It adopts closed loop oil pressure system design, equipped with PQS high-speed servo valve, flow reaction time of 35m / s, pressure reproducibility of less than 0.5%, suitable for high-precision injection products (this servo valve can be optional).
The servo power unit has closed-loop control, good stability and precision, which is two levels higher than the original pressure flow proportional valve
The system pressure and flow feedback control greatly improves the stability of the oil pressure system.
High flow logic pressure relief valve reduces the loss in the pipeline, with obvious switching and good low pressure effect.
The automatic alarm feedback device can set the oiling mode according to the actual lubrication requirements. In case of oil leakage or insufficient pressure in the oil pipe, the alarm will be displayed automatically to remind the operator to check the pipeline, effectively protect the lubrication function of the crank hand, and extend the service life of the crank hand (the full-automatic yellow oil lubrication system of the crank hand can be optional).
Removable oil tank for easy maintenance and repair
Prolong the service life of pump, motor and hydraulic oil by more than one time
