Product Description

According to the special optimization design of PET bottle embryo forming process, the ejecting force is greater and the ejecting speed is faster than that of the large ejector structure.
Equipped with high efficiency servo motor and imported high efficiency gear pump system, power saving and water saving can be up to 20% and 50%, and noise is lower.
The screw barrel structure specially designed for the PET special machine and the data of the corresponding working elements are seamlessly interfaced to realize the normal operation of lower plasticizing pressure, lower current and higher production capacity.
