Precision Brass Stamping Parts with High Electrical Conductivity for Custom Connector Geometry

Precision Custom Brass Stamping Parts for Electrical Connectors are engineered for manufacturers requiring reliable electrical conductivity, accurate dimensions, stable contact performance, and consistent production quality.

METS specializes in the OEM and ODM manufacturing of precision brass stamped components for electrical connectors, terminals, contact plates, connector housings, contact springs, socket pins, grounding clips, and other conductive hardware. Using advanced progressive stamping, compound die stamping, precision punching, bending, forming, and secondary processing, we produce both simple and complex brass components according to customer drawings, samples, CAD files, or technical specifications.

Brass is widely selected for electrical connector components because it provides a practical combination of electrical conductivity, mechanical strength, corrosion resistance, machinability, and formability. Depending on the application, we can work with different copper alloy specifications and provide customized hardness, thickness, geometry, and surface treatment.

Our engineering team works closely with customers from tooling design and prototyping to stamping production, inspection, surface finishing, and final delivery. This integrated manufacturing approach helps reduce tooling communication issues and provides better control over dimensional consistency and production efficiency.

For connector manufacturers, electrical equipment suppliers, automotive electronics companies, and industrial component manufacturers, METS provides a complete solution from custom brass stamping die development to high-volume precision stamped parts production.

Our precision brass stamping components can be used in a wide range of electrical and electronic assemblies.

Precision stamped brass contacts are used for connector terminals, contact plates, socket contacts, connector pins, and conductive components.

Brass stamping is suitable for crimp terminals, wire-end terminals, quick-disconnect terminals, and other cable connection components.

Customized brass contact blades and terminal plates can be designed for PCB connectors requiring stable electrical contact and precise assembly.

Applications include automotive terminals, sensor contacts, fuse clips, electrical control modules, and wiring systems.

Brass stamped components can be integrated into switches, control systems, terminal blocks, industrial connectors, and electrical equipment.

Suitable for small electrical contacts, battery terminals, grounding components, switching components, and internal conductive hardware.

One of METS's key advantages is the combination of stamping die design, die manufacturing, tooling validation, and precision stamping production within one manufacturing workflow.

METS was established in Xiamen and specializes in mould design, mould manufacturing, and precision metal stamping for electronics, automotive components, electrical products, LED components, lead frames, motor laminations, and other industrial applications.

Our engineering team can support the complete manufacturing process:

Customer Drawing -> DFM Analysis -> Die Design -> Tool Manufacturing -> Trial Stamping -> Sample Approval -> Mass Production -> Inspection -> Packaging -> Global Delivery

This integrated process helps customers simplify supplier management and improve communication between tooling development and production.

METS uses precision machining and EDM technologies for stamping die components. Existing METS projects demonstrate fine dimensional control for electrical connector tooling, with some tooling applications designed around very tight tolerances and high-speed progressive stamping.

Quality control can be implemented throughout the manufacturing process:

• Incoming material inspection
• Tooling component inspection
• First article inspection
• Dimensional inspection
• Projector / optical inspection
• Stamping process inspection
• Surface finish inspection
• Final inspection
• Packaging inspection

For precision electrical connector parts, we focus particularly on critical dimensions, hole position, pitch, burr control, contact geometry, plating quality, and overall consistency.

• Die Design Expertise: A high-quality stamped connector starts with a properly engineered die. Our engineers consider material properties, forming sequence, strip layout, burr direction, material utilization, tolerances, and production efficiency during die development.
• Progressive Stamping for High Volume: Progressive dies integrate multiple operations into one continuous stamping process. This is particularly suitable for electrical terminals and connector components requiring consistent dimensions and high production efficiency.
• Custom Engineering Support: Customers can provide a 2D drawing, 3D CAD file, physical sample, or preliminary specification. Our engineers can evaluate the part structure and recommend an appropriate stamping and tooling solution.
• Flexible Surface Treatment: Electrical connector components can require different surface finishes depending on conductivity, corrosion resistance, solderability, contact performance, and assembly requirements.
• From Prototype to Mass Production: METS supports projects ranging from prototype and trial orders to repeat production and large-volume manufacturing.

For electrical connector applications, METS manufactures customized brass terminals using precision progressive stamping.

Typical requirements:

• Brass material
• High dimensional consistency
• Multiple punching and forming operations
• Stable contact geometry
• High-volume production
• Optional surface plating

The progressive tooling approach allows multiple operations to be completed within one production sequence, making it suitable for repeat production.

METS has manufactured brass electrical contact components including socket pins, electrical contact plugs, and connector-related stamped parts. One existing product example uses brass material, progressive/single-hit stamping, approximately 0.75 mm thickness and a stated ±0.02 mm tolerance.

For automotive and industrial electrical applications, brass and copper alloy stamped components can be customized according to the required contact structure, assembly method, material specification, and surface finish.

The product design can be optimized for crimping, soldering, riveting, press-fitting, or housing assembly.

When sourcing electrical connector components, the quality of the stamping die directly affects part consistency, burrs, dimensional stability, material utilization, and long-term production efficiency.

METS combines tooling engineering + die manufacturing + stamping production + quality inspection to provide a single-source manufacturing solution.

Instead of purchasing a stamping die from one supplier and outsourcing production to another factory, customers can work with one engineering team throughout the project.

• Engineering Consultation -> Review drawings and samples
• DFM & Tooling Analysis -> Recommend stamping structure and production method
• Die Design & Manufacturing -> Develop customized progressive or compound tooling
• Sample Production -> Trial stamping and dimensional verification
• Mass Production -> Stable repeat production according to approved specifications
• Quality Inspection -> Dimensional and visual inspection
• Packaging & Delivery -> Customized packaging and international shipment

Every electrical connector has different electrical, mechanical, dimensional, and assembly requirements. METS provides flexible customization options for your specific project.

For purchasing engineers, product designers, and electrical connector manufacturers, the most important factors are not simply the unit price of a stamped component. Tooling reliability, dimensional consistency, material stability, production repeatability, delivery control, and engineering communication all influence the total project cost.

METS therefore focuses on the complete manufacturing process rather than only supplying individual stamped parts.

We can work from:

2D Drawings -> 3D CAD Files -> Physical Samples -> Technical Specifications -> Existing Tooling

Our engineering team evaluates the product structure before production and communicates critical dimensions, material selection, tooling requirements, and manufacturing considerations with customers.

For new connector projects, we can also help evaluate whether progressive stamping, compound stamping, or another forming method is more suitable according to production volume and part geometry.

For electrical connector components, dimensional accuracy is closely related to assembly performance and electrical contact reliability.

Our inspection process can focus on:

• Overall dimensions
• Hole diameter
• Hole position
• Pitch
• Bending angle
• Material thickness
• Burr direction and condition
• Contact geometry
• Surface condition
• Plating condition
• Assembly fit

METS's existing electrical stamping projects emphasize professional engineering, precision tooling, dimensional inspection and quality control throughout production.

Finished brass stamping parts can be packaged according to the customer's product structure and assembly requirements.

Available packaging options include:

• Bulk Packaging
• Plastic Bags
• Trays
• Tape & Reel
• Vacuum Packaging
• Cartons
• Wooden Cases
• Customized Labels

For export orders, packaging can be selected according to transportation method and component sensitivity.
