Computer mouse case injection molding machine manufacturer plastic
for sale mould production line in China
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.
The machine use the high-performance servo dynamic control system,
the oil pump as the power source, having the characteristics as
follow: high response,saving energy, low noise, high-control
precision, and have the breakthrough in the prefect connection of
the electrical servo and hydraulic drive system.
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.
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 70dB, will be much
quieter for your working area.
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.
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.
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.
