We are a reputable manufacturer specializing in precision-machined thermal management components for battery packs. Unlike traditional stamping or brazing methods, our cold plates are produced using high-precision CNC machining, which offers superior dimensional accuracy, tighter tolerances, and greater design flexibility. This process allows us to create complex internal flow channels optimized for maximum heat transfer efficiency.
Our company is dedicated to designing, manufacturing, and distributing high-quality cooling solutions suitable for cylindrical cells, prismatic cells, and pouch cells. For this specific product line, we focus on CNC machined cold plates that deliver exceptional flatness, consistent wall thickness, and reliable leak-free performance — critical requirements for EV battery thermal management.

Q: Are you a trading company or a manufacturer?
A: We are a manufacturer with over 10 years of hands-on experience in precision machining and thermal management solutions.
Q: What makes CNC machining better than stamping for cold plates?
A: CNC machining offers superior dimensional accuracy, flexible channel design, faster prototyping, and no upfront tooling cost. It is ideal for custom or medium-volume production where performance matters most.
Q: What are your payment terms?
A: Standard terms are 30% deposit by T/T, with the remaining 70% balance paid before shipment.
Q: How long does it take for samples and mass production?
A: Sample lead time is typically 10–15 working days (no mold required). Mass production takes approximately 20–30 working days after sample approval.
Q: Do you offer OEM/ODM services?
A: Absolutely. We provide full OEM and ODM services, including custom channel design, material selection, and surface treatment.
Q: Can I get a sample for testing?
A: Yes, we gladly provide samples for quality evaluation. Sample costs may apply for customized designs.
Q: Is it possible to place a small trial order?
A: Yes, we accept sample orders and small batch runs. Our team can also assist with design optimization based on your thermal requirements.
