High-Precision Copper
& Brass Stamping for
Critical Applications.
Specializing in Intricate Geometries & High Conductivity copper components. Expertise in C1100 Copper, Brass, and Beryllium Copper — from multi-compartment RFI/EMI shielding cans to precision spring contacts and seamless sensor housings. DFM optimization for complex forming. Secondary operations: Tin, Silver, and Nickel Plating for superior solderability and anti-oxidation.
Industry Expertise.
We speak the language of your industry — understanding the specific conductivity, purity, and precision requirements that copper demands.
Electronics & Semiconductor
We produce EMI/RFI shielding cans and micro-shell enclosures with wall thickness down to 0.08mm on shells as small as Ø3mm. Tolerance: ±0.01mm. All parts shipped with material test reports confirming IACS ≥99.9%. Tin, silver, or gold plating coordinated in-house.
Technical Capabilities.
Material Mastery — The Right Alloy for Every Application
We specialize in the full copper alloy spectrum: C11000 Oxygen-Free Copper (99.99% pure, maximum conductivity), C26000 Cartridge Brass (70/30, optimal deep drawing), C17200 Beryllium Copper (highest strength-to-conductivity ratio), and C21000 Gilding Metal for decorative applications. Our engineers recommend the optimal alloy for your specific conductivity, strength, and formability requirements.
Micro-Drawing — Precision at the Smallest Scale
We produce extremely small, deep-drawn copper shells for micro-sensors, miniature connectors, and precision electronic components. Our micro-drawing capability achieves wall thicknesses down to 0.08mm on shells as small as Ø3mm — a capability that requires specialized tooling, controlled blank-holder forces, and deep experience with copper's work-hardening behavior.
Surface Treatment Hub — One-Stop Plating Service
Copper parts almost always require surface protection. Our in-house and partner plating services cover: Tin plating (optimal solderability, RoHS compliant), Silver plating (maximum conductivity for high-frequency applications), Gold plating (corrosion resistance for connectors), Nickel plating (barrier layer, wear resistance), and Passivation. We coordinate all post-processing so you receive a finished, ready-to-assemble part.
12-Hour DFM — Copper is Expensive, Waste is Not Acceptable
Copper's work-hardening behavior demands precise blank geometry and draw ratio control. Our free DFM analysis optimizes your blank size, identifies the correct draw ratio to prevent corner thinning, and confirms the appropriate temper to achieve your mechanical requirements without cracking. Quote and DFM feedback within 12 hours.
Our Track Record in Copper.
Zero Material Contamination
Copper purity is non-negotiable for electrical and medical applications. Our dedicated copper production lines use separate tooling, lubricants, and handling procedures to prevent cross-contamination with ferrous metals. Every batch is accompanied by a material test report confirming alloy composition and purity.
Engineering-Led — We Understand Work Hardening
Copper work-hardens rapidly during deep drawing — increasing strength but reducing ductility with each forming stage. Our engineers calculate the precise number of drawing stages and intermediate annealing cycles required to achieve your final geometry without cracking. This knowledge is the difference between a successful part and a scrapped tool.
Cost-Efficient Tooling — Zhejiang & Guangdong Ecosystem
We leverage the manufacturing ecosystems of Zhejiang and Guangdong — China's two premier precision tooling regions — to offer lower-cost, high-precision molds. Our tooling partners have been producing copper stamping dies for 15+ years. Lower tooling costs mean faster ROI on your product development investment.
