Black ABS Plastic Frame Injection Molding | Lighting System Bracket

Product Description

OVERVIEW Custom black ABS plastic frame / bracket produced by single-shot injection molding for lighting system applications. This structural component is designed to hold, support, and align LED modules, light bars, diffusers, lenses, or wiring harnesses within a lighting assembly. It combines dimensional stability, impact resistance, and a consistent matte/smooth black finish for professional OEM integration. MANUFACTURING SPECIFICATIONS • Material: Black ABS (Acrylonitrile Butadiene Styrene), standard or flame-retardant grade available • Process: Single-shot injection molding • Structure: Frame / support bracket with mounting holes, snap-fit features, ribs, and locator bosses • Color: Custom black formulation with uniform color distribution and minimal weld-line visibility • Dimensional Tolerance: ±0.05mm standard; critical alignment features controlled as required • Wall Thickness: Optimized to prevent warpage, sink marks, and stress concentration • Surface Finish: Smooth or textured finish depending on lighting assembly requirements • Tooling: Single-cavity or multi-cavity tooling available for prototype and volume production KEY ADVANTAGES • Stable Support Structure: ABS provides good rigidity and impact strength for long-term fixture support. • Precise Alignment: Mounting holes, slots, and locating features help secure LED boards, lenses, or diffuser panels. • Lightweight Alternative: Replaces metal frames in non-load-critical lighting applications to reduce weight and cost. • Consistent Black Appearance: Uniform pigmentation reduces color variation between shots. • Design Flexibility: Supports snap fits, clips, ribs, standoffs, and integrated cable-routing features. • Cost-Effective Production: Single-shot molding simplifies tooling and maintains repeatable quality. TYPICAL APPLICATIONS • LED panel light frames • Strip light / light bar mounting brackets • Backlit signage support structures • Automotive or appliance interior lighting frames • Commercial lighting housings and internal brackets • Display, indicator, and illumination system components DESIGN NOTE For lighting frames, wall thickness and rib design are balanced to avoid warpage that could misalign optical components. Gate location is selected to minimize flow marks on visible surfaces and to maintain flatness of mounting planes. If the part operates near heat sources, FR-ABS or heat-resistant ABS grades can be evaluated during DFM review. QUALITY ASSURANCE Dimensional check of mounting holes, slot pitch, and flatness. Visual inspection for sinks, flash, short shots, and color consistency. Functional fit-check with mating LED/diffuser components available. FAIR and CMM inspection provided on request.
