Precision Multi-Station Custom-Engineered Metal Stamping Die for High-Volume Connector Parts

Precision Multi-Station Metal Stamping Dies for Connector Parts are custom-engineered tooling solutions designed for the high-volume production of electrical connectors, terminals, contact pins, lead frames, and other precision metal components.

The multi-station stamping die integrates multiple operations into one continuous production process. Depending on the connector design, individual stations can perform piercing, blanking, bending, forming, coining, embossing, notching, and cutoff operations. The metal strip is automatically fed through each station, allowing a finished connector component to be produced efficiently with consistent dimensional accuracy.

For connector applications, precise strip feeding and station-to-station alignment are critical. METS designs progressive and multi-station tooling according to the customer's part drawing, material characteristics, required production volume, press specifications, and tolerance requirements.

Our tooling solutions are suitable for copper, brass, phosphor bronze, stainless steel, carbon steel, and other conductive or spring materials commonly used in electrical and electronic connectors.

With in-house die design, precision machining, wire EDM, grinding, assembly, tryout, and stamping production capabilities, METS provides an integrated tooling solution from initial design review to production validation.

• Multi-station progressive tooling for continuous production
• Custom-designed for connector and terminal geometries
• Suitable for high-speed automated stamping
• Precise punching, bending, forming, and cutoff operations
• Optimized material utilization and strip layout
• Precision-machined die components
• Compatible with copper, brass, bronze, stainless steel, and other metals

Actual specifications are determined by connector geometry, material, strip layout, required tolerance, production volume, and customer's stamping press.

Connector components often combine multiple small features into a compact geometry. A suitable multi-station die can divide these operations into carefully controlled forming stages.

METS engineers develop the strip layout according to:

• Connector geometry
• Material width and thickness
• Feed direction
• Pitch requirements
• Scrap ratio
• Carrier design
• Forming sequence
• Production volume

The goal is to establish a stable material flow while maintaining accurate positioning throughout the entire die.

Punching stations create holes, slots, notches, and other critical features. For connector components, these dimensions can directly affect assembly and electrical contact performance.

Different stations gradually form the terminal or connector profile. Staged forming helps control deformation and reduces the risk of material cracking or dimensional variation.

For selected electrical contact applications, coining or localized forming can be incorporated into the tooling to achieve the required contact geometry.

The final station separates the completed connector component from the carrier strip, allowing continuous automated production.

METS is a professional metal stamping and tooling manufacturer established in Xiamen in 2006. The company specializes in mold design, mold manufacturing, and precision metal stamping for applications including automotive, electronics, electrical components, lead frames, and motor laminations.

Unlike a tooling-only supplier, METS combines die design, die manufacturing, die maintenance, and stamping production within its manufacturing workflow. This helps engineers evaluate tooling from both the die-making and production perspectives.

Critical die components are manufactured using precision machining and wire EDM processes to help maintain dimensional consistency.

Multi-station tooling allows several operations to be completed progressively as the strip moves through the die, reducing manual handling and supporting continuous production.

METS has experience with connector terminals, contact pins, electrical components, brass/copper stamping, and related precision hardware tooling.

Customers can work with one supplier for die development, trial production, stamping, inspection, and subsequent tooling support.

Each die is designed around the customer's:

• 2D drawing
• 3D model
• Material specification
• Tolerance requirements
• Press machine
• Production volume
• Connector assembly requirements

METS' existing tooling portfolio covers a range of electrical and electronic connector applications.

A progressive connector punch die was developed for contactor pin and terminal block components. The tooling supports multiple operations and precision features required for connector manufacturing. The published example specifies a 25-ton press, 0.5 mm material thickness, and progressive die construction.

METS has developed progressive tooling for brass, bronze, and copper electrical contact pins and terminal connectors. The published tooling example uses multiple cavities and is designed for punching and bending operations in conductive materials.

For electrical connector production, METS has supplied progressive tooling with WEDM and grinding processes, automatic strip feeding, and customized die structures. One published example specifies a one-row cavity and a 1,000,000-stroke mold life.

Our multi-station stamping dies can be developed for:

• Electrical connectors
• Automotive connectors

Our engineers analyze the connector geometry and develop the strip layout, station sequence, die structure, and forming strategy.

Approved tooling designs are manufactured through CNC machining, wire EDM, grinding, milling, and other precision processes.

The die is assembled and tested to verify feeding, forming, punching, cutting, and dimensional performance.

Trial parts are inspected against the customer's drawings and technical requirements.

After approval, METS can provide stamping production, tooling maintenance, process support, and subsequent engineering assistance.

Yes. METS provides custom tooling based on customer 2D drawings, 3D models, samples, and technical specifications. The die structure is developed according to the component geometry, material, tolerance, production volume, and press requirements.

Common materials include brass, copper, phosphor bronze, stainless steel, carbon steel, and other suitable strip metals. Material selection can be discussed according to the connector's conductivity, strength, spring characteristics, and forming requirements.

Yes. A multi-station progressive die can combine operations such as piercing, blanking, bending, forming, coining, embossing, and cutoff into sequential stations.

Tolerance depends on the part geometry, material, thickness, tooling structure, and inspection requirements. METS has published connector tooling examples with precision down to approximately ± 0.003 mm for suitable applications. Final tolerance should be confirmed during engineering review.

For suitable connector applications and compatible equipment, METS has published tooling capabilities of up to 600 SPM or more. Actual production speed depends on the material, part geometry, die structure, press, feeding system, and required quality.
