plastic moulding machine,
automatic injection moulding machine
■ The Clamping Parts
The new generation mold locking device and computer emulation optimized parameter makes motions of the moving plate, fixed plate and high rigidity toggle structure, the characteristic of high strength and anti-fatigue is secured. As compared with similar machines, it owns bigger internal spur between tie bars, mold space and mold opening stroke and may process plastic products of bigger size.
■ The Injection Units
Short and forceful double-cylinder injection system is used to ensure the steady injection motion.The strain free fixed mold plate and screw assembly with optimized design help to reach better plasticing capacity and effect. PID temperature control regulate the speed and pressure of injection, pressure keeping, smelting, back pressure and other motions to ensure the quality of formed products and continuation of production.Auto material preparation, drooling proof,and anti cold start lapse functions ensure the high efficent,simple and safe operations.
■ The Hydraulic Units
High efficiency, Energy-saving and high precise proportional pressure and flow variable displacement pump system make the out of the hydraulic system matching the required power for entire machine operation without loss of high pressure throttle and overflow energy. As comparedwith constant displacement pump, t saves power by 30%~60%.A motor with same power may be fitted with an oil pump of bigger displacement and thus accelerates the speed of machine.Besides, the low oil temperature will prolong the service life of sealing elements.
Buffer device is used in every mold opening and clamping oil way to ensure steady mold opening and clamping operation without any impact.Besides, differential mold clamping operation is fitted to ensure high production efficiency.
High Energy saving
Under the ideal working state, Power consumption is 40% less than that of variable displacement pump and 70% less than that of fixed displacement pump, save the cost effectively.
Precise control of low pressure & low flow, repeating precision is less than 0.5%. Weight error of the products is 0.4%~0.7%, with semi-close loop system nearly.
With steady capability, servo gearshift dynamical control system has equipped with pressure feedback device with high precision and sensitivity, which forms close-loop precision control, cycle time effectively shortened and improving production efficiency.
Oil temperature rise slowly
The system can restrain arising of oil temperature, so smaller oil cooling system can be used in the machine.
Control pressure and flow simply by inputting simulated voltage of pressure & flow into the computer.
Different from ordinary fixed pump injection molding machine, servo power-saving injection molding machine is working only when necessary. And working noise is less than LOG-A8 series, will be much quieter for your working area.

Hydraulic closed loop and motor speed closed loop is realized by control system with the features of high repetition, high linearity, high linearity, high efficiency, high precision, fast response, low rejection rate,low noise, low vibration and long service life, High-rigidity template design with T shot andordinary threaded hole facilitates the mold installtion. Oil filter equipment of high performance and high precision can keep the grease within NAS8. Color control system is adopted.
2. Injection Unit Features
2.1 Injection unit adopts duble-cylinder design, more higher injection pressure, more simpler structure and lower malfunction rate.
2.2 Enlarged-cylinder, adopting two -cylinder design,effectively prevent the adhesive-material leaking phenomenon because of the machine vibration or other reasons when the nozzle is under high-speed operation.
2.3 Adopting graphite bush, improving the wear-resistance, reducing the frequency of using lubrication oil effectively improve the cleanness of the injection part.
2.4 Injection cylinder adopts low-frictional seals, improving the response rate and improve the stability under the complicated processes of injection.
2.5 Bridge-style design, for different L/D plastic parts.
