Integrated finishing for custom parts

Surface Finishing

BGCNC coordinates secondary finishing directly with your parts manufacturing project—from process selection and supplier matching to quality checks and delivery. Keep finishes, dimensions, and production batches aligned without managing a separate finishing supplier.

One project

Manufacturing and finishing coordinated through one team.

50+ partners

A proven manufacturing network across Dongguan and China.

Engineering-led

Recommendations matched to material, application, and cost goals.

A single point of coordination

Finishing built into the parts project

Surface treatments can affect appearance, corrosion resistance, fit, and final dimensions. We coordinate finishing alongside machining and fabrication so requirements are considered before production—not passed between disconnected suppliers at the end.

Our engineers review material, geometry, application, quantity, and target cost to recommend a manufacturable route. Depending on the part, this may include anodizing, plating, passivation, electropolishing, powder coating, blasting, polishing, or heat treatment.

Specification alignment

Clarify finish type, color expectations, coating thickness, masked areas, and inspection needs before work begins.

Dimensional awareness

Review threads, mating surfaces, tight tolerances, and other features that may be affected by finishing.

Appearance and durability

Coordinate visual requirements and functional performance, including corrosion and wear resistance.

Batch consistency

Manage production handoffs and quality checks to support consistent results across parts and repeat orders.

Process planning at a glance

Match the finish to the part and its purpose

Finish selection depends on the base material, functional needs, visual standard, and production plan. Use this overview as a starting point; final process suitability is confirmed against your drawing and requirements.

Project attribute Coatings & plating Conversion finishes Mechanical finishes Thermal treatments
Material Selected metals and fabricated components, subject to coating compatibility. Material-specific treatments for aluminum and stainless steel, among others. Metal and fabricated surfaces evaluated for the required texture or appearance. Suitable alloys assessed against performance and dimensional requirements.
Process Coordinate coating or plating type, coverage, thickness, masking, and finish. Review treatment specifications, surface condition, and functional requirements. Align surface preparation and texture with appearance and application needs. Plan treatment and any required secondary machining or inspection.
Applications Components needing corrosion protection, wear performance, or a defined appearance. Parts requiring material-appropriate surface protection or cleanliness. Enclosures, brackets, panels, and parts with specified surface appearance. Components where material properties or service conditions guide treatment.
Lead time Quoted with manufacturing and finishing steps considered together. Depends on specifications, supplier capacity, and inspection requirements. Planned around surface preparation, production volume, and batch schedule. Confirmed for the selected route, quantity, and any follow-on operations.
