Precision Injection Molding
Huashuo provides high-performance automotive plastic injection molding services for battery housings, sensor enclosures, and other regulated automotive applications, guaranteeing dimensional stability and assembly interface consistency.
Huashuo manufactures housing assemblies, equipment structural components, and functional internal plastic parts.
With strict tolerance control capabilities, we support high-volume injection molding production, enabling scalable manufacturing from pilot validation to mass production.
Insert Molding Technology
Insert injection molding integrates metal inserts with plastic structures, enhancing the mechanical strength and long-term stability of precision automotive injection-molded parts.
We manufacture wiring harness connector housings, pressure sensor assemblies, and ignition switch structural components.
Our high-precision insert positioning ensures stable metal-to-plastic interface bonding, supporting repeatable batch production.
Two-Color Injection Molding
Two-color injection molding sequentially injects two distinct materials within a single cycle to produce integrated components, enhancing functionality, durability, and assembly efficiency.
Huashuo frequently employs two-color injection molding for automotive interiors, electronic housings, sealing components, and control interfaces.
Combining rigid plastics with elastomers or specialty materials ensures part durability under demanding automotive conditions such as high temperatures, UV exposure, and mechanical stress.
Materials Used in Automotive Injection Molding

General Automotive Plastics
PP and ABS offer excellent processability, impact resistance, and chemical stability. They are commonly used in automotive interior and non-structural components such as instrument panels, door trim panels, and center console structures.

Engineering Plastics for Automotive Systems
PC and PC/ABS offer outstanding dimensional stability, high impact resistance, and heat resistance, making them widely used in automotive electronics and lighting components, electronic control system housings, and similar applications.

High-Performance Engineering Plastics
PA6, PA66, and PBT feature high mechanical strength, wear resistance, and thermal stability, commonly employed in automotive structural parts, engine compartment components, cooling system parts, and structural assemblies.

Advanced Automotive Polymers
PPS and PEEK are suited for high-performance and high-temperature automotive environments, offering outstanding heat resistance, chemical resistance, and long-term durability. They are the optimal materials for fuel system components and high-temperature connectors.
