Details


1. High-fficiency mixing PET screw with ceramic heater highly increase the plasticizing speed and shot weight, lowers the plasticizing temperature and AA value, also lowers the shrinkage of preform, while achieves better transparency.

 


 
The design of the PET screw injection molding machine is very important to the preform injection molding process. Usually, the screw used in PET injection is of poor quality and is easy to cause problems. Therefore, the PET injection machine must have its own special screw. Because PET is a heat-sensitive material, it is easy to form high-temperature molecular chains, which will reduce the molecular weight, produce acetaldehyde, and reduce the quality of the preform.

In the tube, it is mainly through the rotation of the screw compressor that the ester particles are sheared and melted. If the screw is compressed and sheared Excessive heat generation may cause thermal cracking of PET. Therefore, the PET injection screw should be designed for low shear, and the goal is to melt crystalline PET polyester pellets. The compression ratio is too high or too short will cause the compression of the large shear length; while the screw compression ratio generated by the low shear heat is insufficient, the polyester pellets may not be completely melted, so the preform crystals are atomized, and the feed tube cannot be completely eliminated The air is easy to cause bubbles in the preform.

 

 
2.  With pin valve interface, special pine valve control system, more process adjustment.
 

 

3. Increasing ejector force and ejector stroke, adapts with PET preform drawing.


 

4. The servo motor control system can save energy by 30%~50%. And the variable pump control system can save energy by 20%~30%.
