In the evolving automotive industry, the demand for lightweight, durable, and cost-efficient plastic parts has never been greater. PENGHENG, a leading manufacturer of automotive components, meets this demand through advanced blow molding and injection molding techniques that ensure product strength, consistency, and efficiency in production.
Injection and blow moulding are complementary processes that, when combined strategically, provide unparalleled design flexibility and structural performance. At PENGHENG, we utilize injection blow molding to manufacture parts that require detailed shapes and precise tolerances—ideal for air ducts, fluid reservoirs, and housing components within the engine bay or HVAC system.
The process begins with injection molding a preform, which is then transferred to a blow mold where it’s expanded using pressurized air. This dual-step manufacturing process creates plastic parts with uniform wall thickness, superior dimensional stability, and high impact resistance. Unlike standard molding techniques, injection and blow moulding at PENGHENG enable us to create complex geometries while minimizing material waste.
Our facility is equipped with modern machinery capable of high-volume, repeatable production. We work closely with OEMs and tier suppliers to customize blow forming plastic parts to fit the specifications of various vehicle platforms, including electric and hybrid models. Our process reduces cycle times, supports lightweighting efforts, and promotes sustainability by lowering material consumption.
By mastering both blow molding and injection molding, PENGHENG has become a trusted partner in automotive innovation. We don’t just deliver parts—we offer engineered solutions for future-ready vehicles.
