PET is a Common Seen Resign Material

PET is a common seen resin material in daily life. The melting point of PET is around 245 degrees Celsius. Existing methods for achieving high temperature applications with PET involve the complicated insertion of premoulded neck into the preform mould and the body is then moulded in PET. This in turn is blown into an oversize bottle which is transferred to an oven at 220 to 230 degrees Celsius for 30 seconds producing up to 40 percent crystallinity and causing the bottle to shrink to smaller than the final size. A second blowing step then gives a container of required dimentsions with high crystallinity and capable of withstanding 90 degrees temperatures.

PET bottles are with features of high strength, good transparency, non-toxic, anti-penetration, light weight, high production efficiency, so it has been widely used.

PET plastic molding process can beĀ  plastic injection moulding, extrusion molding, blow molding, coating, bonding, machining, plating, electroplating, vacuum metallization, printing and so on.
