Zhonghanda machines thin-wall housings, lens barrels, heat sinks, camera parts and wearable device components with attention to cosmetic surfaces, small features and assembly fit.
Precision aluminum, copper, stainless steel and plastic parts for compact electronic products, optical devices and thermal assemblies.
01 / Industry challenge
Visible housings and optical brackets need consistent machining marks, controlled edges and finish-ready surfaces.
02 / Industry challenge
Compact electronics parts often combine thin walls, pockets and small threaded features that can distort during machining.
03 / Industry challenge
Heat sinks, copper inserts and aluminum plates must balance heat transfer, weight and assembly fit.
Representative part families and machining concerns for this application market.
Milled aluminum housings with datum faces, pockets, threaded holes and black anodized appearance requirements.
Turned sleeves, rings and precision threaded components for optical assemblies.
Thermal plates, fins and conductive features machined from aluminum or copper.
Lightweight brackets and frames with cosmetic surfaces and repeatable assembly features.
Material Options
Material recommendations are selected around strength, weight, corrosion resistance, conductivity, appearance and assembly requirements.
Selection logic
Operating environment and cleaning requirements
Feature geometry, wall thickness and tool access
Surface finish, documentation and inspection plan
Application material notes
Material recommendations are matched with part function, finishing route, inspection level and batch repeatability.
Common for lightweight housings, brackets and anodized visible parts.
Useful for thermal spreaders, conductive inserts and heat-transfer details.
Used where insulation, weight reduction or non-metallic contact surfaces matter.
A clear production workflow helps global buyers reduce communication gaps, control risk and move from drawings to finished CNC parts with confidence.
Manufacturing workflow
Review CAD files, drawings, tolerances, material grade, finish requirements and manufacturing risks before quoting.
Select CNC milling, turning, grinding, EDM, finishing and inspection routes around geometry, quantity and lead time.
Machine parts with controlled setups, tooling, fixtures and in-process checks for critical dimensions.
Coordinate anodizing, plating, polishing, blasting, coating, marking and other secondary processes when required.
Complete final checks, prepare inspection evidence when requested, protect parts and arrange export shipment.
