We are an established thermal management solution provider with deep expertise in stamping, vacuum brazing, and surface coating technologies for liquid-cooled cold plates.
Our core business centers on designing, producing, and delivering high-performance heat exchangers tailored for energy storage battery packs utilizing cylindrical, prismatic, and pouch cells. The 104S series features an epoxy powder-coated finish on a stamped and vacuum-brazed aluminum substrate, marrying the economic benefits of precision stamping with the robust, hermetic joints achieved through vacuum brazing, plus enhanced surface protection via epoxy coating.
We deliver comprehensive thermal regulation solutions, including serpentine tube assemblies for cylindrical formats (18650, 21700), liquid cooling panels for prismatic modules, and channel plates for pouch configurations. The epoxy-coated 104S cold plates are engineered specifically for large-scale deployment in energy storage and high-power EV battery modules.
We look forward to leveraging our technical capabilities to build a lasting partnership with you, recognizing that dependable thermal control is paramount in energy storage and electric vehicle performance. Our core competencies include:
In-house die development — Rapid prototyping and precision tooling for stamped components, ensuring swift first-article validation.
Flexible geometries — Cold plates can be formed in diverse stamped profiles to accommodate varying pack architectures and spatial constraints.
Engineering support — Our seasoned R&D team offers professional consultation on design feasibility, thermal simulation, and manufacturing optimization.
Integrated solutions — Beyond heat exchangers, we supply complementary insulation layers and thermal interface pads, delivering a complete thermal management package.

A: We are a direct manufacturer with more than a decade of hands-on experience in stamping, vacuum brazing, coating, and thermal management system integration.
A: Vacuum brazing yields clean, high-strength, leak-proof joints without flux residues or oxidation, making it ideal for mission-critical applications such as energy storage and EV battery cooling.
A: We typically require a 30% deposit via T/T, with the remaining 70% settled prior to shipment.
A: New die development and complimentary sample production (up to 5 kg) generally require 15–20 days. Following sample approval, mass production is typically completed within 25–30 days.
A: Yes, we offer full OEM and ODM capabilities, encompassing custom stamping dies, brazing process parameters, and coating specifications.
A: Certainly. We welcome sample requests for quality verification and thermal performance testing.
A: Yes, we accommodate trial orders and provide design assistance to support your initial validation phase.
