pet plastic water bottle making injection molding machine 500ml pet mould preform production line cost in China

Clamping system: Faster response, steable and high rigidity.

Injection system: Accurate and flexible, lower rejection rate.

Control system: omputer and simple operation,molding data memory system.

Power system: Energy saving, high efficient and precise.

Metal parts: The thickness of our frame, metal plate and wallboard are thicker than other company.

Ceramic heating loop: Uniform heating, better thermal insulation properties so good for production.

Visiable lubrication system: on time clean, avoid cast steel parts abrasion and broken.

Oil treasure: Filter of hydraulic oil, good for pump and valves.

Long working life: Imported spare parts and updated version.

Aftersales service: Professional & timely.

.Due to new toggle design with optimized kinematics.

Take 200-ton clamping unit for example
Vm: Moving speed of movable platen
Vo: Moving speed of oil cylinder

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 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

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.
