Standard Features
With deep experience and in accordance with PET preform characteristics, we have improve a lot to be fit for PET preform production.
Professional PET screw and barrel with L/D 1: 23 have higher mixing and plasticizing abilities. High torque screw driving system ensures screw's injection speed.
Big channels for cooling water regulating meet requirements for mold cooling.
Large eject force ensures multi cavity PET performs to be taken out efficiently.
PID controlled barrel with exact temperature.
We supply all PET preform and bottle production "Turn-Key" solution.

Continuous casting slabs or primary rolling slabs are used as raw materials, heated by a stepping furnace, and dephosphorized by high-pressure water, and then enter the roughing mill. The rough rolling material is cut through the head, tail, and then into the finishing mill, and computer-controlled rolling is carried out. After the final rolling, it will go through laminar cooling (computer-controlled cooling rate) and take-up by the coiler to become a straight hair coil. The head and tail of straight hair curls tend to be tongue-shaped and fish-tailed, with poor thickness and width accuracy, and often have wavy, folded, tower-shaped and other defects on the edges. The coil is heavier and the inner diameter of the steel coil is 760mm. (Generally used in the pipe-making industry.) After straightening the hair through the cutting head, tail cutting, trimming and multi-pass straightening and smoothing finishing lines, and then cutting or re-rolling, it becomes: hot rolling steel plates, flat hot rolled steel coils, slitting tapes and other products. If the hot-rolled finishing coil is pickled to remove scale and coated with oil, it will become a hot-rolled pickled coil.
