Servo Injection Moulding Machine 400 Ton , Horizontal Injection Molding Machine
LOG-400S8 Injection Molding Machine
1. LOG Injection Molding Machine Details
■ 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 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 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, it 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.
■ The screw unit
LOG afford universal screw for large customers, in order to meet diverse needs of injection; also for different plastic types and porcess product feature, to design special screw to satisfy customer's demand.
such as : UPVC/PMMA/PA/PC/CP/PPS/PET screw.
■ The Mould Adjusting Units
The automatic mold adjusting device driven by hydraulic motor adopts gear coupling drive, features steadiness, high-efficiency and saving mold loading time.
