Lamp Housing Gravity Die Casting For Hardware & Lighting Fixtures

Technical Advantages

Full In-House Manufacturing

Mold design and fabrication, gravity die casting workshop, T6 heat treatment, CNC machining, surface treatment, and inspection lab — all centralized under one roof. No outsourcing. From molten aluminum to finished and blasted part, we maintain full control over lead time, quality consistency, and batch traceability.

Design for Manufacturability (DFM) Support

Before tooling production begins, we provide a detailed DFM report covering mold filling analysis, solidification behavior, riser and gate design, and machining allowance optimization. For lamp housings like this 2.2 kg A356 component, we focus on heat sink fin thickness uniformity to ensure consistent thermal performance, wall thickness transitions between the fin array and mounting flange, and riser placement to eliminate shrinkage in thick sections.

Expertise in Complex Castings

We specialize in thermal-management and structurally demanding aluminum castings — such as lamp housings, heat sink enclosures, pump housings, and fluid-handling components. Our gravity die casting process delivers dense grain structure, superior internal soundness, and consistent mechanical properties, while T6 heat treatment enhances strength and dimensional stability for precision machining. We work with A356, A380, ADC12, and other standard or custom aluminum alloys to match your strength, thermal, and corrosion requirements.

Certified Raw Material Sourcing

We charge only certified primary aluminum ingots into our electric melting furnaces. Chemical composition is spectrometer-verified and adjusted in real time before casting. Degassing and fluxing practices ensure clean molten metal with low inclusion content — critical for maintaining consistent A356 thermal conductivity and surface quality across gravity die casting production.

Full Batch Traceability

Every production batch is identified by a unique heat number. Chemical composition reports, mechanical test records (tensile strength, hardness, elongation), T6 heat treatment charts, and dimensional inspection data are compiled into a traceable dossier — from ingot lot to finished lamp housing.

Extensive Alloy Expertise

We work with a comprehensive range of casting aluminum alloys — A356, A380, ADC12, A360 — and can tailor alloy selection to your specific requirements. Whether your application demands thermal conductivity for LED heat dissipation, pressure tightness for sealed enclosures, or corrosion resistance for outdoor exposure, we match the alloy and heat treatment to your needs.

Service Advantages

 Dedicated Cross-Functional Support

A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage and a single point of contact for all technical and commercial matters.

Fast Response & Transparent Communication

Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project. For lamp housings, first-article inspection reports including dimensional layout and material certification are provided before batch production begins.

After-Sales Support

Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support. Flexible MOQ with pilot order options available for new casting projects.
