What is injection molding?
Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers that do not melt during the injection moulding of some lower-temperature thermoplastics, can be used for some simple injection moulds.

What is the performance of polyurethane (PU)?
According to different polymerization reaction products, PU is commonly divided into rigid polyurethane and soft polyurethane. Rigid polyurethane has high strength, good toughness, good thermal insulation, good waterproof effect, simple molding process and high production efficiency; soft polyurethane has good elasticity, good sound absorption, aging resistance, chemical resistance, etc., comprehensive The mechanical properties far exceed materials such as pvc.

Which parts of the car are used for polyurethane plastics?
Polyurethane foam is widely used in automotive interiors and vibration-absorbing parts, such as coating materials, polyurethane rigid plastic sheets, polyurethane elastomers, soft seat foam materials, decorative parts, sofa leather, car roof accessories; the most applications It is a variety of soft and hard polyurethane foam materials, which have vibration isolation, sound insulation, noise reduction, heat preservation and heat insulation; PU can also be made into polyurethane coatings, adhesives, and sealants for vehicles. The PU representative parts on the car include dashboard, rearview mirror, bumper, seat cushion, headrest, steering wheel, dashboard anti-vibration pad, pillar trim, front roof lining, window frame, roof and side roof Shelf decoration, door liner, sun visor, rear top shelf decoration, etc.
