Superior Thermal Management for Extended LED Lifespan
LED lighting heat dissipation failures cost replacements. Our custom aluminum die casting optimizes fin density and airflow channels, reducing junction temperature
Every precision die casting part undergoes CNC machining, ensuring exact fitment with LED modules, drivers, and housings-eliminating rework
Street & High Bay Lighting That Works in Harsh Environments
Unlike extruded profiles limited to simple shapes, our high-pressure die casting enables intricate internal channels, mounting bosses, and integrated features
Our OEM heat sink manufacturer capability combines heat dissipation fins, mounting brackets, and wire channels into a single custom aluminum die casting part, cutting procurement and inventory costs.
As a direct small-to-medium aluminum die casting factory, we control mold making, casting, CNC, and finishing in-house

AI-Powered supplier vetting
SummaryNingbo Beilun Jiawei Machinery Co., Ltd. is identified primarily as a private Chinese manufacturer/factory in Ningbo, Zhejiang, with business activities covering non-ferrous metal casting, mold production, mechanical-part processing, hardware, plastic-product, metal-material, and auto-part products. The supplier demonstrates customization, ODM, and OEM capabilities, including customization from samples, designs, and full specifications, and reports new products within the past year. Production evidence includes six production lines, but the factory does not continuously reconcile quantities for each batch or mass-production order. Written procedures and records exist for supplier-service assessment, corrective and preventive actions, and customer complaints. Overseas-service infrastructure is limited: no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported. Financial information is represented only by reporting years, without sufficient evidence to assess...
Supplier typeThe supplier is identified as a Manufacturer/Factory and private owner in China, while another record describes the company nature as a trading company and its type as Combined. Its stated business scope includes casting, mold manufacturing, mechanical-part processing, and hardware-related manufacturing and sales, indicating a mixed manufacturing and trading structure.
After-Sales capabilityThe supplier has written procedures and records for service-capability assessment, corrective and preventive actions, and handling customer complaints. However, it reports no overseas warehouse, showroom, agent, branch, or offline trade-show participation, and the stated number of countries offering overseas services is zero, indicating documented service processes but limited overseas service coverage.
R&D capabilityThe supplier reports new products within the past year and provides ODM services, demonstrating product-development activity. It also reports no available SDK, but SDK availability is not sufficient by itself to negate the broader evidence of R&D and ODM capability.
Production capacityThe supplier is identified as a factory with six production lines, and its business scope includes casting, mold manufacturing, mechanical-part processing, and hardware-product manufacturing. A stated weakness is that the factory does not continuously reconcile quantities for every batch or mass-production order, which may affect production-control reliability.
Customization capabilityThe supplier explicitly provides customization from samples, full customization, and customization from customer designs. It also reports ODM availability, giving direct evidence of broad customization and original-design manufacturing capability.
Client casesThe supplier reports providing OEM services to well-known brands, which is direct evidence of at least one type of customer experience. However, no customer names, products, project details, or verifiable case records are supplied, so the breadth and strength of its customer portfolio cannot be established.
Product Q&A
Q:What is a die cast aluminum heat sink for LED lighting?
A:
A die cast aluminum heat sink is a thermal management component manufactured through high-pressure die casting using ADC12 or A380 aluminum alloy. It absorbs and dissipates heat generated by LED chips, preventing overheating and ensuring optimal light output and longevity in LED downlight, street light, and flood light fixtures.
Q:Why choose die casting over extrusion for LED heat sinks?
A:
Die casting enables complex 3D geometries, integrated mounting features, and internal cooling channels that extrusion cannot achieve. For custom LED lighting heat dissipation solutions, die casting offers greater design freedom, tighter tolerances, and lower per-unit costs at medium-to-high volumes.
Q:What aluminum alloy is best for LED heat sink die casting?
A:
ADC12 aluminum alloy is the industry standard for LED heat sinks due to its excellent castability, thermal conductivity, and cost efficiency. A380 and A360 are alternatives offering better corrosion resistance or higher purity for anodized aluminum finishing applications.
Q:Can you provide custom aluminum die casting for my LED fixture design?
A:
Yes. As an OEM heat sink manufacturer with in-house mold design and CNC machining capabilities, we transform your LED fixture specifications into production-ready precision die casting parts. We support custom fin geometries, mounting interfaces, and surface treatments including anodizing and powder coating.
Q:What surface treatments are available for die cast aluminum heat sinks?
A:
We offer anodized aluminum finishing (Type II/III), powder coating, electrophoresis, sandblasting, and chemical conversion coating. Anodizing enhances corrosion resistance and thermal emissivity while providing aesthetic options in black, natural silver, or custom colors for architectural LED lighting.
