How is quality control ensured?

Every batch undergoes rigorous validation including spectrometer analysis, X-ray flaw detection for porosity, CMM dimensional verification, and optional functional tests like salt spray resistance.

What is the optimal production volume for this solution?

This die-casting solution is most cost-effective for production runs exceeding 1,000 pieces, where the near-net-shape process significantly reduces secondary machining costs.

AI-Powered supplier vetting

SummaryThe supplier demonstrates manufacturing and customization capabilities across hardware, molds, rubber, plastics, non-ferrous metal alloys, communication equipment, and electronic products. It reports six production lines, peak-season fulfillment within 15 working days, valid manufacturing contracts with associated subcontractors, and quality, complaint-handling, corrective-action, and finished-product inspection procedures with records or instructions. Exporting has reportedly begun for two years, with both agency export and self-operated import/export capability, and markets including Southeast Asia, the Middle East, and domestic sales. However, the supplier reports no stock service, overseas warehouse, overseas showroom, or overseas agent/branch capability, and no available SDK. Evidence for certifications, financial credibility, and customer cases is insufficient; financial figures are omitted.

Supplier typeThe supplier appears to be a manufacturer with a broad scope covering hardware, molds, rubber products, plastics, non-ferrous metal alloys, communication equipment, and electronic products. Six production lines and valid contracts with associated subcontractors further support a manufacturing-oriented supplier profile.

After-Sales capabilityThe supplier has clear procedures and followed records for customer complaints and corrective/preventive actions. However, it reports no overseas warehouse, showroom, agent, or branch capability, so the evidence supports procedural service handling but not broad overseas after-sales infrastructure.

Production capacityProduction capability is supported by six production lines, peak-season fulfillment within 15 working days, documented finished-product inspection, quality assurance, and valid manufacturing contracts with associated subcontractors. The supplier also reports no in-stock service capacity, which limits inventory-based fulfillment but does not negate its manufacturing capability.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. Its business scope includes manufacturing and development activities across several relevant product categories, indicating broad customization coverage.

Product Q&A

Q:What materials are used for the heatsinks?

We primarily use ADC12 and A380 aluminum alloys. ADC12 offers exceptional fluidity for thinner fins, while A380 provides a superior balance of casting, mechanical, and thermal properties.

Q:What is the Minimum Order Quantity (MOQ)?

The Minimum Order Quantity is 10 pieces. This allows for flexibility for both small trials and larger production runs.

Q:What is the typical lead time for production?

The average lead time is within 15 workdays during off-peak seasons and within one month during peak seasons.

Q:Do you offer customization services?

Yes, we provide full OEM and ODM services. We accept 3D models (STEP, IGS, X_T) and offer DFM optimization, rapid prototyping, and customization from samples or designs.

Q:What payment terms are accepted?

We accept LC, T/T, D/P, PayPal, Western Union, and small-amount payments. Incoterms include FOB, CIF, CFR, and EXW.
