Surface Finishing Services FAQs

Can I order surface finishing together with CNC machining or sheet metal fabrication?

Yes. Surface finishing is available as part of our CNC machining, sheet metal fabrication, and 3D printing services, allowing you to receive fully finished parts from a single supplier.

Do you provide surface finishing as a standalone service?

Our surface finishing services are primarily provided for parts manufactured by Zhuohua Hardware, ensuring better quality control, compatibility, and delivery efficiency.

Which surface finish is best for aluminum parts?

It depends on your application. Type II anodizing is commonly used for decorative and corrosion-resistant finishes, while Type III hard anodizing is recommended for improved wear resistance and durability.

Which surface finish offers the best corrosion resistance?

Hard anodizing, electroless nickel plating, powder coating, and chromate conversion coating all provide excellent corrosion protection, depending on the material and operating environment.

Will surface finishing affect part dimensions?

Some finishing processes, such as anodizing, electroless nickel plating, and powder coating, add material thickness and should be considered during the design stage. Our engineers will recommend appropriate tolerance compensation when necessary.

Can you match specific colors?

Yes. Selected finishing processes, including anodizing and powder coating, can be supplied in various colors based on standard color systems or customer requirements.

Can multiple surface finishes be combined?

Yes. Certain finishes can be combined, such as bead blasting with anodizing or brushing with electropolishing, depending on the material and application.

What materials can be surface finished?

We support a wide range of materials, including aluminum, steel, stainless steel, copper, brass, titanium, and selected engineering plastics.

What is the typical lead time for surface finishing?

Lead time depends on the finishing process, material, and production quantity. Surface finishing is integrated into our manufacturing workflow to minimize overall delivery time.

How do I choose the right surface finish?

Simply provide your application, material, and performance requirements. Our engineering team will recommend the most suitable surface finishing solution based on function, appearance, durability, and cost.
