Custom Tight-Tolerance Brass Stamping Parts with Corrosion-Resistant High-Speed Progressive Stamping for Electronics

Precision-engineered conductive components designed for electronic devices, connectors, terminals, switches, sensors, relays, PCB assemblies, and other electrical applications.

METS specializes in the development and production of custom brass stamped parts, electronic contacts, terminal components, conductive plates, connector contacts, shielding components, clips, brackets, and precision hardware. Our integrated capabilities cover stamping die design, tooling manufacturing, precision stamping, secondary processing, inspection, and customized packaging.

Brass is widely selected for electronic components because it combines good electrical conductivity, mechanical strength, corrosion resistance, formability, and stable dimensional performance. Depending on the application, customers can select different brass grades, material thicknesses, hardness levels, and surface treatments.

METS is an integrated manufacturer specializing in stamping die design, die manufacturing, precision stamping, and metal component production.

Our factory combines engineering and production capabilities instead of treating tooling and stamping as completely separate processes. This allows our engineering team to consider the relationship between:

• Customer Drawing / Sample
• DFM Analysis
• Material & Process Evaluation
• Progressive / Compound Die Design
• Precision Tool Manufacturing
• Trial Stamping
• Sample Inspection
• Customer Approval
• Mass Production
• Final Quality Inspection
• Packaging & Delivery

This integrated workflow helps reduce communication gaps between tooling development and production and provides better control over critical dimensions.

Electronic components often contain small critical features where dimensional variation can affect assembly or electrical performance. METS's quality control process includes:

Verification of material grade, thickness, surface condition, and customer-specified material requirements.

Critical punch, die, insert, guide, and forming components are inspected during tooling development.

Initial stamped samples are measured against approved drawings before mass production.

Critical dimensions can be monitored during production, including:

• Part length
• Width
• Hole diameter
• Hole position
• Pitch
• Bending angle
• Contact height
• Material thickness
• Burr condition
• Surface condition

Finished parts can undergo dimensional, visual, quantity, and packaging inspection before shipment.

We can work with C26000, C26800, C28000, H62, H65, copper, phosphor bronze, beryllium copper, and other customer-specified copper alloys.

Tolerance depends on the material, part geometry, dimensions, tooling structure, and production process. METS's tooling projects include precision capabilities around ± 0.002-±0.003 mm for suitable tooling features, while finished-part tolerances are established according to the engineering drawing.

Yes. METS has experience with small electronic contacts, connector terminals, socket pins, and other precision stamped components.

Depending on the application, our brass stamping range can cover approximately 0.05 -3.0 mm. Existing METS projects include material thicknesses from 0.05 mm upward.

Yes. METS provides DFM analysis, progressive die design, tooling manufacturing, trial stamping, die adjustment, and production support.
