Custom Electronic Metal Stamping Parts
Techsun manufactures custom electronic metal stamping parts for OEMs and component suppliers, including electrical terminals, conductive contacts, connector metal components, EMI shielding covers, grounding clips, spring contacts, and precision hardware.
Electronic components often require more than dimensional accuracy. Contact geometry, material temper, burr direction, and surface condition can affect electrical connections, spring behavior, shielding interfaces, and assembly fit.
We manufacture parts to customer drawings and specifications, with engineering support for material selection, stamping feasibility, tooling development, and production planning.

Electronic Metal Stamping Parts We Manufacture
Techsun produces custom stamped components for electrical connections, electromagnetic shielding, grounding, and mechanical assembly. Our manufacturing experience includes the following component groups.
Electrical Terminals, Contacts & Connector Components
We manufacture stamped electrical terminals, conductive contacts, and metal components for connectors and electronic assemblies.
Depending on the part design, important features may include contact area geometry, insertion-related dimensions, forming accuracy, burr orientation, and specified plating surfaces.
Material grade and temper are reviewed according to the component’s electrical and mechanical requirements. For spring-type contacts, forming consistency and the specified contact geometry are particularly important.
EMI Shielding Covers & Metal Enclosures
Techsun manufactures stamped EMI shielding covers and metal shells for electronic assemblies.
These components may require accurately formed edges, retaining tabs, mating features, and consistent contact interfaces. We review the drawing requirements that affect fit and mechanical contact with the surrounding assembly.
The electromagnetic shielding performance of the finished product depends on the complete design, material properties, electrical continuity, and installation conditions.
Grounding Clips & Spring Contacts
We produce custom grounding clips and spring contact components for electronic equipment.
Material temper, bend geometry, contact features, and springback are considered during tooling development. These factors help maintain the specified shape and fit of the component during repeat production.
Where contact force or repeated deflection is critical, the required acceptance criteria should be defined by the customer and verified through suitable testing.
Electronic Equipment Brackets & Fastening Hardware
Techsun also manufactures stamped brackets, retaining parts, and fastening hardware used in electronic equipment assemblies.
These components are produced according to customer drawings, with attention to hole positions, formed features, material thickness, and the specified surface finish.
Manufacturing methods are selected based on the component design and production requirements.
Critical Manufacturing Requirements for Electronic Stamped Parts
The manufacturing requirements for an electrical contact differ from those of a shielding cover or a mounting bracket. Techsun reviews the functional features identified in customer drawings before selecting tooling and inspection methods.
Contact Geometry & Burr Orientation
For electrical terminals and connector contacts, the location and condition of stamped edges may affect mating surfaces and component insertion.
We review contact dimensions, critical edges, punch direction, and allowable burr conditions according to the drawing. Where required, tooling design and secondary operations are planned to meet the specified edge requirements.
Springback & Formed Contact Features
Spring contacts and grounding clips may require controlled bends and formed features.
Material temper, bend radius, forming sequence, and tooling adjustment influence the final component geometry. These factors are considered when evaluating manufacturing feasibility and dimensional consistency.
Shielding Interfaces & Assembly Fit
Stamped shielding covers rely on accurately formed features to fit their intended assemblies.
Retaining tabs, contact edges, cover dimensions, and mating surfaces are reviewed against the customer drawing. Shielding effectiveness is a product-level requirement and must be evaluated under the specified test conditions.
Plated Surfaces & Critical Dimensions
Electronic terminals and contacts may require specified plating on functional surfaces.
The material, plating type, coating thickness, and dimensional requirements should be reviewed together. Plating can affect finished dimensions and surface characteristics, so the drawing should clearly identify critical areas and acceptance criteria.
Material & Plating Considerations
Electronic stamped components are manufactured from materials selected for their electrical, mechanical, and forming characteristics.
Copper & Copper Alloys
Copper stamping and selected copper alloys are used for conductive terminals, contacts, and connector components. Conductivity, temper, strength, and forming requirements should be considered when specifying the material.
Brass
Brass stamping is used for selected electrical contacts, terminals, and connector metal parts. The appropriate grade depends on the required combination of formability, conductivity, and mechanical properties.
Stainless Steel
Stainless steel may be selected for shielding components, grounding hardware, spring-type parts, and mechanical brackets where its material properties meet the application requirements.
Aluminum & Carbon Steel
Aluminum and carbon steel may be used for selected electronic equipment hardware and structural components, depending on the part design and surface requirements.
Plating Requirements
Tin, nickel, silver, gold, and other specified finishes may be considered for suitable electronic components. The choice depends on contact requirements, corrosion resistance, wear conditions, and the customer’s technical specification.
Techsun evaluates material and finishing requirements during drawing review and coordinates applicable finishing processes according to the agreed project scope.
Tooling, Production & Quality Control
Techsun supports custom electronic stamping projects from drawing review through tooling development and production.
Our engineering team evaluates part geometry, material thickness, critical dimensions, forming requirements, and estimated production volume to select a suitable manufacturing approach.
For appropriate components, in-house stamping die development and progressive die stamping production can support repeatable manufacturing. The tooling process is planned around the features identified as critical in the approved drawings.
Inspection Priorities by Component Type
| Component Type | Key Inspection Considerations |
|---|---|
| Electrical terminals & contacts | Contact dimensions, formed features, burr condition, specified plating requirements |
| Connector metal components | Mating geometry, critical dimensions, insertion-related features, surface condition |
| EMI shielding covers | Formed profiles, retaining tabs, mating edges, assembly fit |
| Grounding clips & spring contacts | Bend geometry, formed dimensions, contact features, material condition |
| Electronic brackets & hardware | Hole positions, bend angles, surface condition, dimensional conformity |
Inspection methods and acceptance criteria are established according to customer specifications. Where electrical, spring-force, or shielding performance testing is required, the test method and acceptance limits must be agreed before production.
