Yongzhu Casting: Premium Aluminum Die Cast Solutions for the Lighting Industry
What kind of road lighting die castings does YONGZHU Casting produce?
With over 20 years of experience in high‑pressure die casting, Yongzhu Casting is the partner of choice for precision roadway lighting components.
We deliver customized solutions tailored to your design challenges, uphold ISO‑certified quality with full traceability from molten alloy to finished part, and maintain competitive lead times through 24/7 production and optimized logistics.
Choose Yongzhu Casting for die‑cast parts that not only meet but exceed industry demands.
Trust Yongzhu Casting for durable die‑cast luminaires. Our A380A and ADC12 alloys endure rigorous salt‑spray and outdoor testing with full metallurgical analysis. We hold ≥ 1 mm wall thickness and ≥ 0.6° draft angles for precise tooling and robust strength.
Yongzhu Casting’s unified process merges mounting bosses, conduit entries, and heat‑sink fins into one casting, cutting up to 30% of machining time. Every part meets NFPA and IES LM‑79 standards, verified in our labs for electrical safety and light output.
Our cast‑in fins ensure superior heat dissipation to extend LED lifespan, while UV‑stable powder coatings or anodized finishes resist UV and road‑salt. Slip‑fitter brackets and pole adapters withstand winds up to 150 km/h, confirmed by finite‑element testing.
What Our Customers Say
Our 180 W roadway luminaire shifted from a sheet‑metal box to a one‑piece die‑cast shell with cast‑in fins. Weight fell from 5.4 kg to 4.3 kg, and junction temperature during LM‑80 test dropped 10 °C. Lumen‑maintenance now projects L90 at 69 000 h.
Die‑cast swivel yokes from Yongzhu replaced welded steel arms on our 2 kW sports‑flood modules. After 1 000 h IEC 60068‑2‑64 random vibration at 25 m above roofline, no cracks or aim drift. Installation torque screws cut from 12 to 4.
Architectural uplights for a seaside casino needed 1 500 h ASTM B117. Yongzhu’s die‑cast body with 120 µm polyester exceeded 2 000 h with < 2 mm creepage. winning that tender added us$ 4.7 m revenue.”
Our previous sand‑cast housing required machining and still failed ingress. Yongzhu delivered a die‑cast body with cast‑in cable glands; it cleared IP69K jet‑spray and ATEX Zone 2 flame‑path inspection without re‑work, saving six weeks on type approval.
A topology‑optimised die‑cast fin pack lowered LED board temp from 92 °C to 78 °C on our 30 000‑lm factory high‑bay. That moved efficacy to 158 lm/W, qualifying us for a utility rebate worth US$ 1.1 M across 22 warehouses.
Six clip‑on extrusions became one die‑cast housing with cast‑in PCB bosses. Assembly time per luminaire fell from 3 min 40 s to 1 min 48 s. At 400 k units/year, labour savings top 8 700 hours annually.

Lighting industry customer concerns
What makes aluminum die cast parts ideal for lighting fixtures?
Aluminum’s thermal conductivity of ~273 W/(m·K) and high strength‑to‑weight ratio ensure efficient heat dissipation and durability, while die casting delivers thin walls (≥ 0.89 mm) and tight tolerances (±0.05 mm) for complex shapes.
How does aluminum die casting improve thermal performance in LED fixtures?
The high conductivity of aluminum rapidly channels heat away from LEDs, preventing lumen depreciation and extending fixture life.
What is the typical lifespan of aluminum die cast lighting components?
With corrosion‑resistant alloys and powder‑coat finishes, lifespans exceed 20 years in outdoor applications under normal conditions.
Can aluminum die cast parts withstand harsh outdoor conditions?
Yes—die‑cast aluminum alloys exhibit excellent corrosion resistance, especially when combined with appropriate coatings, ensuring longevity in urban and coastal environments.
What lighting sectors benefit most from die cast components?
Roadway, industrial, commercial, residential, and entertainment lighting all leverage die cast parts for precision, durability, and thermal management.
How precise are aluminum die cast housings for lighting applications?
Die casting routinely achieves dimensional tolerances of ±0.05 mm and surface finishes down to Ra 0.8 µm, critical for lens sealing and aesthetic quality.
What design limitations exist with aluminum die casting for complex shapes?
Minimum wall thickness is generally 0.89 mm with draft angles ≥ 0.6°; extremely deep cavities may require specialized tooling.
How does aluminum alloy selection affect lighting component performance?
Common die cast alloys like A380 balance cost and performance, while higher‑strength alloys (e.g., A356) improve fatigue resistance for dynamic fixtures.
What are the sustainability benefits of using aluminum die cast parts in lighting?
Aluminum is infinitely recyclable without property loss, and high scrap‑return rates (>90%) reduce environmental impact.
How does the cost of aluminum die casting compare to other manufacturing methods?
At volumes above 10,000 pcs, die casting often undercuts machining and fabrication by 20–30% per unit due to reduced labor and material waste.
What is the typical production volume for aluminum die cast lighting parts?
Economical for runs from 5,000 to millions of units, supporting both short‑run prototypes and large scale OEM contracts.
How quickly can custom aluminum die cast parts be delivered?
Standard lead times: 8–12 weeks for tooling, then 2–4 weeks for production batches.
Are aluminum die cast lighting components recyclable?
Yes—recycled aluminum comprises up to 75% of die casting feedstock, saving 95% of the energy needed for primary aluminum production.
How does aluminum die casting impact the weight of lighting fixtures?
Lightweight aluminum (2.7 g/cm³) reduces fixture weight by up to 30% compared to steel, easing installation and lowering shipping costs.
What finishing options are available for aluminum die cast lighting parts?
Powder coating, anodizing, wet paint, and plating ensure corrosion protection and customizable aesthetics.
How do you ensure corrosion resistance in aluminum die cast lighting components?
Choice of alloy, post‑cast heat treatment, and sealant‑compatible coatings (e.g., epoxy‑polyester powder) prevent oxidation.
Can aluminum die casting accommodate integrated mounting features for lighting?
Yes—complex bosses, ribs, and flanges can be cast in one operation, reducing secondary machining.
What tolerances can be achieved with aluminum die cast lighting parts?
±0.05 mm for critical dimensions; ±0.1 mm for general features, ensuring reliable assembly.
How does the global LED lighting market trend affect demand for die cast components?
The market reached USD 94.5 billion in 2024 and is growing at 10.4% CAGR, driving demand for precision cooling housings and heat sinks.
