PET Injection Molding machine

• BaIanced double injection cylinder technology makes screw to have evenly distributed force during fast injection,
• Fivestar Hydraulic motor with big torque,
• Ensure the excellent plastic molding condition.
• Research and develop different screws according to difierent iniection condition, suitable for the progressive demand and greatly improve the injection quality.
• 5-point twin toggle clamping system by modular optimization software designing. Strong clamping with rapid and stable, tomeet the strict clamping condition.
• Mould height adjustment by hydraulic driven gear system with rapid and stable.
• Automatic mould height adjustment as per the setting clamping force(optional).

 Injection moulding machine Adopting Europe technology,hydraulic unit adopts proportional pressure and flow control,the pressure and the speed can be adjusted,stable movement curve and gentle shock,the computer is imported from Industry family. The LCD displaying screen with high clarity has Chinese and English language to use. Close-loop PID temperature control with the advantage of high precision. The operating table of the injection moulding machine have two safety, one is machine safety, another is electrical safety, that ensures the operators’s  safety.

 1.  PET material because of its exceptional performance, are generally used two-step molding process, by the preform injection molding machine to produce a 24-hour After cooling, the internal molecular structure of their re-arranged in an orderly manner, and blowing for the next step to create good conditions, so that more excellent blowing performance products. Such as the famous Coca-Cola Company is currently using this technology. Its production processes are as follows:

  PET materials→Dryer→Injection machine(with Chiller)→Bottle Proferms

  2. Cap on in the injection molding machine is completely automated production, its production process is as follows::

  PP/PE material→load material→dry→heat material →injection→cooling molding  →preforms→caps
