Custom Copper‑Alloy Thermal & Connecting Components for North‑American Energy‑Storage System Integrator
Custom Copper‑Alloy Thermal & Connecting Components for North‑American Energy‑Storage System Integrator
Project Overview
Client: North‑American energy‑storage system integrator
Material: Copper alloy C11000
Tolerance: ±0.012 mm
Surface Treatment: Anti‑oxidation passivation
Service: DFM consultation → Prototype machining → Material certification → Batch production & cross‑border shipment

Challenge
The customer required copper alloy connecting and heat‑dissipation parts for their commercial energy‑storage cabinets. Copper material tends to deform during high‑speed machining, causing unstable dimension consistency in mass batches. In addition to tight mechanical requirements, components must resist oxidation under large temperature fluctuation. Every shipment needs complete material certificates and dimensional inspection reports for North‑American compliance audit. Previous suppliers could not keep stable dimensional repeatability, resulting in high rework rate.

Our Solution
Our engineering team optimized the machining path to release internal stress of copper alloy, reducing deformation risk during processing. We adjusted cutting speed and tool selection specially for soft copper material. All finished parts go through professional anti‑oxidation passivation treatment to meet long‑term working condition requirements. Each production batch is fully sampled and inspected; we provide CMM test reports, material mill certificates for customs and customer quality audit.

Result
Prototypes passed customer’s full‑set reliability test at first trial. Batch‑to‑batch dimensional consistency meets project specification. Zero field failure after parts assembled into energy‑storage cabinets. Chenrong Precision became one of their qualified long‑term suppliers for copper precision components.

Client Testimonial
“Copper parts are always tricky for mass production. Chenrong understood our pain points from the very beginning. They deliver consistent quality and supply all required compliance documents. Communication works well despite time‑zone gap. We are satisfied with their service for energy‑storage hardware.”
