PET injection molding

Injection molded PET parts

We process polyethylene terephthalate PET and PET compounds by injection molding for a wide range of industries and mechanical applications. As an injection molding solution provider and expert, our priority is to develop custom molded parts and meet our customers' needs.

Injection molding of PET compounds 

Polyethylene terephthalate (PET/PETP) is a thermoplastic, semi-crystalline polymer with very high dimensional stability, excellent wear resistance and low coefficient of sliding friction. Other characteristics of polyethylene terephthalate (PET) are its good chemical resistance and low moisture absorption. PET plastic is well suited for injection molded parts with high demands on dimensional accuracy and surface quality.

PET processing technology

We process PET at our injection molding sites. Our engineering knowledge and experience guarantee our customers excellent product properties of the PET molded parts.
Gentle processing of PET materials during the injection molding process is critical.  This ensures the desired mechanical properties of the molded part, including short dwell times of the material in the cylinder and the avoidance of overheating and thermal damage.
Prior to this, good drying of the material is of paramount importance. As PET material has a certain water absorption, it absorbs a lot of water during transport, storage and use. This must be removed before the pellets are used, otherwise the properties will change during injection molding.
Our state-of-the-art material drying systems ensure optimum preparation of the material and the necessary residual moisture and supplies the injection molding machines automatically.

Pet injection molding solutions - application examples

Improved efficiency and lower friction losses in mechanical applications with PET injection molded parts - our expertise in injection molding thin-walled and dimensionally stable PET parts such as rings, sliding elements, washers or bushings improves the durability and running conditions of applications. 
Wear-resistant PET molded parts are also used in clutches, bearings or gears in industrial applications such as mechanical engineering and automotive, or in the food industry for guide rails, stop units, rollers and grippers.
