Product info

Rotational plastic bumper is a plastic bumper that is integrally formed using rotational molding technology, using imported polymer materials
Ethylene is the main raw material, and the material is uniformly coated and formed by rotating and heating the mold.
The product has no welds or splices, with good overall structural integrity and smooth appearance lines.

Integrated molding: seamless overall, uniform structural strength, and no welding weak points
Material selection: High toughness imported PE is used to prepare excellent impact resistance and rebound performance,
Imported polyethylene is the main raw material, and the material is uniformly coated and formed by rotating and heating the mold.
The product has no welds or splices, with good overall structural integrity and smooth appearance lines.
Surface treatment: After forming, the surface is smooth and can be directly sprayed or treated with leather lines.

Process features: Imported polyethylene (PE) material is used to produce automotive fuel through integrated rolling molding
Box. Complex irregular surfaces can be designed according to the chassis space of the vehicle model, fully utilizing the structural space of the vehicle
No need to splice welds, eliminating the risk of leakage.

Key process: Mold design: Based on the 3D data of the chassis, the mold is opened to accurately reserve the positions of the oil pump port and pipeline interface
Embedded preset: fix the metal threaded embedded part in the designated position in the mold and integrate it with the body after molding
Wall thickness control: Accurately control the wall thickness of each part through rotation speed and heating time to ensure the structure
Structural strength; Cooling demolding: Control the cooling rate to prevent deformation and ensure dimensional accuracy.
