Integrated Thermal Housing: Combines structural protection and heat dissipation in one die cast aluminum part.
Custom Fin and Pin Designs: Optimized fins, pins, or cooling channels increase surface area for better heat transfer.
Design and Development Support: Our engineers help with concept design, DFM, mold flow, and prototype validation.
Build to Drawing: We produce strictly according to your 2D and 3D drawings, tolerances, and specifications.
Multi Industry Applications: Suitable for PCB, power management, EV battery, solar, inverter, telecom, IGBT, LED, data center, energy storage, charging pile, medical, and industrial automation.
Lightweight and Hard Surface: Aluminum die casting reduces weight, while anodizing or hard coating improves surface hardness.
Excellent Heat Dissipation: High thermal conductivity alloy and optimized geometry reduce hot spots and extend service life.
Corrosion Resistant Finish: Anodizing, powder coating, and other surface treatments protect against harsh environments.
Prototype to Mass Production: Low MOQ, fast sample lead time, and stable batch quality for your projects.
Cost Effective Thermal Solution: Die casting reduces parts count, assembly steps, and total system cost.

AI-Powered supplier vetting
SummaryThe supplier is a Foshan-based manufacturing factory with broad metal-processing equipment and extensive customization capabilities. It reports ISO9001:2015 certification, documented finished-product inspection instructions, OEM and ODM services, and 17 years of export experience, with exports representing 51%–70% of total sales. Production capacity is supported by valid contracts with associated subcontractors and 15 qualified service suppliers, while standard lead time is one month in both peak and off-season. Key limitations include no in-stock capacity, overseas warehouse, or overseas showroom; no new product information in the past year; no available SDK; incomplete written records for service assessment, corrective actions, and complaint handling; no recent regular fire drills; and no Fortune 500 customer collaboration evidence.
Supplier typeThe supplier is identified as a factory located in Nanhai District, Foshan, with manufacturing-related business activities covering construction manufacturing, glass-fiber-reinforced plastic products, new materials, building materials, hardware, furniture, and design services. This indicates a manufacturing-oriented supplier with a relatively broad stated business scope.
CertificationsThe supplier reports an ISO9001:2015 certificate in both its sustainable-development-related information and management-system certification information. The provided slices do not specify the certificate’s scope, issuing body, or validity period, but they explicitly confirm certification holding.
After-Sales capabilityThe supplier accepts multiple quotation and payment terms, has a service-capability assessment record, and reports one-month average lead times in both peak and off-season. However, complaint handling and corrective/preventive action procedures lack written records, and the supplier has no in-stock service, overseas warehouse, or overseas showroom capability, indicating limitations in service infrastructure and documented execution.
Production capacityThe supplier lists CNC, die casting, grinding, lathe, milling, polishing, punch, and spark erosion equipment, has valid manufacturing contracts with associated subcontractors, and reports 15 qualified service suppliers. It also has 17 years of export experience and one-month average lead times, supporting substantial production and fulfillment capability.
Customization capabilityBoth manufacturing and R&D-related information explicitly lists full, minor, flexible, design-based, and sample-based customization, and the supplier provides OEM and ODM services. This directly supports a broad ability to adapt products to customer designs and samples.
