Enclosures & Covers
Define wall and rib geometry, gasket zones, mounting datums and cover interfaces. Mark cosmetic surfaces and provide any specified ingress or leakage test requirements.
Protection & thermal control
Metal Components for Electronics
Cast and machined enclosures, heat sinks and housings for electronics, with defined thermal, sealing and mounting interfaces.
Enclosures · Thermal interfaces · Mounting
Metal Parts for Electronic Assemblies
Connect the component drawing to the enclosure, circuit board and mating hardware. Identify thermal, sealing, electrical contact and mounting requirements before selecting the production route.
Heat Sinks & Thermal Housings
Identify the thermal path, contact faces, cooling features and mounting pattern. Define flatness, surface condition and the interface requirements used by the assembly.
Frames & Connector Housings
Provide connector locations, board or hardware mounting points, threads and mating references. Coordinate clearances, grounding contacts and coating boundaries.
Thermal · Sealing · Contact · Appearance
Coordinate Functional Surfaces & Finishes
Identify which surfaces transfer heat, seal, make electrical contact or define appearance. Agree component inspection separately from any specified assembly-level thermal, ingress or shielding test.
| Feature group | Define on the drawing | Agree for acceptance |
|---|---|---|
| Thermal contact surfaces | Contact areas, flatness, surface condition, mating references and coating restrictions. | The inspection condition of contact faces and the scope and responsibility for any specified thermal validation. |
| Sealing & enclosure joints | Gasket zones, sealing faces, cover interfaces, threads and assembly references. | Dimensional checks and the method, setup and acceptance criteria for any required ingress or leakage test. |
| Grounding & shielding interfaces | Electrical contact zones, masking boundaries, mating surfaces and specified coating build. | Contact-surface inspection and the scope, assembly condition and acceptance method for specified electrical or shielding tests. |
| Cosmetic & mounting features | Cosmetic zones, finish references, connector positions, mounting patterns and assembly stack-up. | Appearance limits, protected features and dimensions checked after finishing or insert installation. |
Geometry, interfaces & production demand
Select the Manufacturing Route
Review enclosure geometry, material, quantity and design maturity together. Include the machining, masking and inspection needed to deliver the final interface condition.
CNC Machining
Review prototypes or machined production parts against stock form, access and workholding. Identify thin sections, pockets, connector openings and critical contact faces.
Review manufacturing route →Die Casting
Review alloy, wall and rib layout, draft and tooling for the proposed enclosure or housing. Coordinate parting features with cosmetic, sealing and machined surfaces.
Review manufacturing route →Casting + Finish Machining
Combine the cast housing with machined mounting datums, sealing faces, contact areas and threads. Agree allowances, masking and the final measurement condition.
Review manufacturing route →Finishing, inspection & delivery requirements
Surface Finishing
Define coating build, masked contacts, sealing faces and cosmetic zones together with the final dimensions.
Review requirements →Quality Planning
Agree dimensional checks, surface acceptance, specified test methods and required inspection records.
Review requirements →Product Assembly
Specify inserts, fasteners, mating checks, handling protection and packaging for finished contact and cosmetic surfaces.

Application context & review inputs
Prepare the Electronics Component Review
Show how the metal part interfaces with the board, cover, connectors and thermal or sealing elements. Identify the surfaces whose condition must be preserved through machining, finishing and assembly.
Drawing package checklist
- Controlled 2D drawing and 3D model with revision.
- Board, cover and connector references with critical mounting dimensions.
- Thermal contact areas, sealing zones and operating environment.
- Material, finish, grounding contacts, masking and cosmetic limits.
- Order quantities, schedule, specified tests and required records.
Electronics application notes & review sequence
Application context
Metal electronics parts can provide protection, heat spreading, grounding, shielding, mounting, and cosmetic structure. Enclosures, heat sinks, covers, frames, and connector housings often combine thin walls with machined interfaces.
Engineering priorities
Review thermal path, wall and rib layout, gasket or sealing zones, connector locations, grounding contacts, coating and masking, cosmetic limits, ingress or leakage tests, flatness, thread strategy, and assembly stack-up.
Process Planning
We compare geometry, quantity, material, design maturity, secondary operations and inspection requirements before recommending CNC machining, die casting, or a combined route.
Project Information
Provide the CAD model, controlled drawing, order quantities and annual demand, operating environment, critical interfaces, finish, tests, documentation, packaging, and any customer-specific quality requirement.
Coordinate the Review Steps
1. Define functional requirements
Capture the operating environment, interfaces, load, quantity, material condition, and acceptance criteria and records.
2. Select the manufacturing process
Compare material, stock or casting form, machining access, secondary operations, finishing, and production risk.
3. Verify critical characteristics
Inspect the agreed characteristics with suitable equipment, methods, sampling, and controlled records.

Before You Send the Drawing
How should coating and grounding areas be coordinated?
Identify cosmetic zones, grounding contacts, sealing faces, threaded features, masking boundaries, coating build, connector interfaces, and the acceptance method on the drawing.
What application information should I share?
Describe interfaces, operating environment, loads, failure risks, demand, critical features, finish, tests, documentation, cleanliness, and packaging.
When should customer-specific quality requirements be provided?
Include applicable standards, approvals, validation, documentation, traceability and change-control requirements with the RFQ so their scope and availability can be confirmed before order acceptance.
