Knowledge Compilation on Injection Molding Services for Automotive Products
Injection molding of automotive products is a demanding and large-scale field within the plastics industry. This document compiles information on the injection molding of various automotive products.
Common categories of automotive products manufactured through injection molding directly impact the driving experience and aesthetics.
1. Instrument Panel: Large, complex components, often utilizing two-color injection molding, soft-touch injection molding, or combined with IMD/INS in-mold decoration technology to enhance texture.
2. Door Trim Panels: Also large components, involving the combination of various materials and processes.
3. Center Console/Sub-instrument Panel: Integrates multiple functions, such as cup holders and storage compartments, resulting in complex structures.
4. Air Vents: High demands on appearance and movement mechanisms.
5. Seat Components: Headrests, armrests, side panels, etc.
6. Steering Wheel: Often uses overmolding, with a metal or hard plastic base layer and an outer layer of soft TPU or TPE.
7. Decorative Strips: Such as imitation wood grain and imitation carbon fiber trim strips, extensively using IMD/INS technology.
8. Buttons/Switches: High demands on dimensional accuracy and surface wear resistance.
