Surface finishing of machined aluminum components

Services

Finishing Add-Ons Services

Finishing services are available as part of our machining projects. Bead blasting, polishing, ultrasonic cleaning, and water-based paint with oven curing are completed in-house. Anodizing, passivation, plating, and powder coating are arranged through approved finishing suppliers, allowing machining and finishing to be managed under a single project.

Finishing Coordination

Finishing Coordinated Through Your Machining Supplier

Surface finishing often involves processes that are not performed within the same facility as machining. We manage both in-house finishing operations and approved external processes as part of a single manufacturing project, helping ensure consistency from machining through final delivery.

Single Project Ownership

Machining, in-house finishing operations, external finishing processes, and final inspection are managed under the same drawing and purchase order. Customers work with a single supplier throughout the project.

Dimensional Planning Up Front

Finishing requirements are reviewed at quotation. Where coating thickness may affect critical dimensions, machining allowances and tolerances are evaluated before production begins.

Inspection Throughout the Process

Parts are inspected after machining, before external finishing when required, and again before shipment. Drawing requirements remain the reference point throughout the manufacturing and finishing process.

Operational Mechanics

How Finishing Is Managed

Surface finishing requirements are reviewed during quotation and managed as part of the overall manufacturing process. The following steps help ensure machining, finishing, and inspection remain aligned throughout the project.

How Finishing Is Managed — ① Drawing Review & Process Planning

① Drawing Review & Process Planning

Finish specifications are reviewed during quotation. Where coating thickness may affect critical dimensions, machining allowances and tolerance requirements are considered before production begins.

How Finishing Is Managed — ② In-House Preparation

② In-House Preparation

Bead blasting, polishing, ultrasonic cleaning, and water-based paint with oven curing are completed in-house according to drawing and finish requirements.

How Finishing Is Managed — ③ External Finishing Coordination

③ External Finishing Coordination

Processes such as anodizing, passivation, plating, and powder coating are completed through approved finishing suppliers. Drawings, finish specifications, masking requirements, and inspection criteria are provided as part of the process documentation.

How Finishing Is Managed — ④ Final Inspection & Packaging

④ Final Inspection & Packaging

Finished parts are inspected for dimensional compliance, finish quality, and any specified coating requirements before packaging and shipment.

For Your Incoming QA

Documentation You Can Hand to Your QA

Production records, finishing documentation, and inspection notes can be provided with shipment where required. The goal is simple: your receiving team should be able to see what processes were performed, who performed them, and what was checked before shipment.

Drawing & Finish Specification Record

The approved drawing, finish requirements, masking instructions, and any agreed dimensional considerations are retained as part of the production documentation and can be referenced during incoming inspection.

Finishing Traceability

For outsourced finishing operations, the process performed and the finishing supplier used are recorded as part of the project documentation. Relevant references can be provided when required.

Inspection Record

Critical dimensions and finish-related requirements are checked before shipment and recorded against the drawing requirements. Inspection notes can be included with the production documentation package.

Common Questions

Frequently asked about finishing add-ons

Is surface finishing offered as a standalone service?

Finishing is provided as part of our machining projects rather than as a standalone service. Customers ordering machining work can include finishing requirements in the same project, and we manage both the in-house and external steps under one drawing and purchase order.

Which operations are performed in-house, and which are arranged externally?

Bead blasting, polishing, ultrasonic cleaning, and water-based paint with oven curing are completed in-house. Anodizing, passivation, plating, and powder coating are arranged through approved finishing suppliers and managed against drawing requirements.

Does anodizing or plating affect part dimensions?

Coating thickness can affect critical dimensions, particularly on fit features. Finish requirements are reviewed during quotation so machining allowances and tolerances can be planned before production begins, rather than discovered at incoming inspection.

Do you provide inspection or test reports for finished parts?

We do not generate lab-style inspection reports. Production records, finishing documentation, and inspection notes recorded against the drawing requirements can be provided with shipment when required.

Can customers specify a particular finishing supplier?

Yes. If you have an approved finishing supplier or specification, it can be incorporated into the project plan. Otherwise, finishing operations are routed through suppliers we have worked with previously.
