· Production Process Introduction
- Design & Engineering: Collaborate with our team to finalize CAD designs, tolerances, and specifications for your custom cold plate assembly.
- Raw Material Selection: High-grade aluminum plates are inspected for material composition and thermal conductivity before production.
- CNC Machining: Multi-axis CNC mills machine the coolant channels, sealing grooves, and mounting holes on both plates.
- Deburring & Cleaning: All sharp edges are removed, and parts are thoroughly cleaned to prepare for assembly and finishing.
- Assembly & Testing: Plates are mated and tested for leak-proof integrity, followed by surface treatment (if required).
- Quality Control: 100% dimensional inspection using coordinate measuring machines (CMM) and pressure testing for leak-proof performance.
· Packaging and Shipping Methods
- Packaging: Each cold plate assembly is individually wrapped in anti-static foam or plastic sleeves to prevent scratches. Bulk orders are packed in sturdy export-grade cartons with internal dividers for maximum protection. Custom branded packaging is available upon request.
- Shipping: We offer flexible global shipping options, including sea freight, air freight, and express courier services (DHL, FedEx, UPS). All orders include full tracking information, and we support EXW, FOB, CIF, and other Incoterms as required.
· Frequently Asked Questions (FAQ)
Q: What is your minimum order quantity (MOQ)?
A: Our standard MOQ for custom components is 10 pieces. For prototype or low-volume orders, we offer production runs starting at 1 piece to support your project development.
Q: What is the typical lead time for orders?
A: Standard orders are processed and shipped within 15–25 business days after payment confirmation. Complex or high-volume orders may require 25–40 business days, depending on design complexity and quantity. Expedited production is available for urgent orders upon request.
Q: Can you work with my custom CAD designs?
A: Yes! Our engineering team works directly with your CAD files (STEP, IGES, DWG, etc.) to ensure parts are machined to your exact specifications. We also offer design support to refine concepts for manufacturability and thermal performance.
Q: Do you provide quality certifications?
A: All products are manufactured under ISO 9001 quality standards. We can provide material test reports (MTR), dimensional inspection reports, and compliance documents upon request.
Q: Is this cold plate assembly suitable for high-power applications?
A: When manufactured from high-conductivity aluminum (1050/1100) with optimized channel design, this component can effectively dissipate heat in moderate to high-power applications. We can also recommend design modifications (e.g., increased channel density or integrated fins) for extreme thermal environments.
