Preform Injection Molding Machine

Shenzhen J&D group has specialized in manufacturing the PRT injection machine since the 1980s. Based on the experience of the preform mould, we have special designed the PET injection machine for preform mould. Our products include separated pressure holding system-25:1 PET specialized screw, double-pump hydraulic system-guarantee a better plastify performance and a shorter injection period. Besides, there is an outside mould cooling system.

PLC control unit: JND series adopts the most advanced technique. This high-property system builds the operator a good way to communicate with the machine. United operation attitude and logical structure make the machine friendlier to operate.

PET injection unit: improved length to diameter rate (25:1), longer machine base and powerful motor higher the PET plastify performance and guarantee the PET preform quality. The stronger top cylinders automatically move out the finished product.

Mould locking unit: the new generation toggle mould locking device and computer emulation optimized toggle parameter makes motions of the moving plate fast and steady. When combining the box type moving plate, fixed plate and high rigidity toggle structure, the characteristic of high strength and anti-fatigue is secured.

Auto mould thickness adjust unit: the mould thickness is adjusted by the gear driven by the hydraulic motor. It is suitable for all different thickness mould. And the photocell detector guarantees high precision.

Hydraulic unit: high efficiency, energy saving and high precise proportional pressure and flow variable displacement pump system makes the hydraulic output match the required power for entire machine operation without high pressure throttle and overflow energy loss.
