Applications
Which electronics projects we take on
Electronic components are defined by function—managing heat, controlling EMI and maintaining precise connector alignment. Customers come to us for heat sinks and cooling plates, shielded enclosures, RF housings and connector hardware machined from conductive and thermally efficient metals, with critical dimensions controlled to drawing requirements.
Why machine electronics parts with Tongyong
From functional prototype to production batches
We machine thermal-management, shielding and connector components for electronics using CNC milling, turning, 5-axis machining and EDM in aluminium, copper and stainless steel. Engineering review helps balance thermal performance, EMI control, fit and manufacturability before production begins.
Electronic components must manage heat, control EMI and maintain reliable mechanical interfaces. We use production-grade materials and controlled inspection to support prototypes, low-volume batches and repeat production.
ISO 9001 Quality Management
A documented quality management system supports consistent process control, inspection and traceability for applicable projects.
Prototype to Production Support
We support one-off prototypes, low-volume batches and repeat production according to project requirements.
Broad Machining Capabilities
CNC milling, turning, 5-axis machining, Swiss-type turning, EDM and surface finishing for electronic metal components.
Flexible Project Support
Project planning is adapted to part complexity, quantity, material and inspection requirements.
Experienced Engineering Support
Our team reviews drawings, materials, tolerances and functional requirements to support manufacturable electronic components.

Common questions
Electronics machining FAQs
Can you machine copper and aluminium for thermal parts?
Yes — high-conductivity aluminium and copper for heat sinks, cooling plates and busbars, machined for thermal performance and fit.
Can you hold micron tolerances?
Critical features from around ±0.01 mm, verified by CMM and kept consistent batch to batch.
Do you make EMI shielding and RF housings?
Yes — shielded enclosures, RF and microwave housings with cavities and walls held to tight tolerance.
Prototypes and production?
Both — from functional prototypes to repeatable production batches.
What files do you need?
A 3D model (STEP / IGES) plus a drawing for critical dimensions, tolerances and finish.
