Automotive Door Panel Assembly

Designed for vehicle interior acoustic and aesthetic integration, this door panel assembly features a large-scale curved body with functional recesses for storage and speaker mounting. The structure combines a black textured main substrate with an orange accent trim plate and simulated gold stitching details, creating a premium cabin appearance while providing necessary enclosure for internal wiring and mechanisms.

Manufacturing such oversized coverage parts requires strict control over surface flatness and contour tolerances to ensure seamless fitment with adjacent interior components. Key processing challenges include maintaining dimensional stability across the large open areas to prevent warping, ensuring uniform seam gaps between the dual-color sections, and preserving the integrity of thin-walled speaker grille structures without sink marks or deformation during formation.

Leveraging SLA stereolithography 3D printing and vacuum casting equipment, high-fidelity prototypes can be produced for rapid design verification and fit-checks before mass production tooling. For engineering plastic injection molding runs using materials like ABS or PC, the facility utilizes precision CNC machining centers for mold fabrication and coordinate measuring machines to validate critical mounting points and surface profiles against OEM specifications.
