Introduction to PET preform for exhaust injection molding machine accessories

PET bottles have strong applicability and are widely used in daily necessities, daily chemical packaging and other fields.So how is PET formed? At a certain temperature and pressure, the mold is filled with raw materials and processed by an injection molding machine into a preform with a certain thickness and height corresponding to the mold.

Polyethylene terephthalate (PET) is the main type of thermoplastic polyester, also known as Polytelene terephthalate in EnglishPETOr PETP (also known as PET), commonly known as polyester resin. It is a condensed polymer of terephthalic acid and ethylene glycol, collectively referred to as thermoplastic polyester or saturated polyester along with PBT. PET is a highly crystalline polymer with a milky white or pre yellow color, with a smooth and glossy surface. Good resistance to creep, fatigue, friction, and dimensional stability, with low wear and high hardness, possessing the toughness of thermoplastic materials; Good electrical insulation performance, less affected by temperature, but poor corona resistance. Non toxic, weather resistant, chemically stable, low water absorption, and resistant to weak acids and organic solvents.

Exhaust injection molding machineIt is a special injection molding machine that directly injects PET raw materials into products without drying them. The PET preforms directly injected by the injection molding machine are very good in terms of transparency and aesthetics.at the same timeSave a lot of electricity costs for enterprises and significantly improve product quality.
