Sheet Metal
Surface Finishing

Choosing the right surface finish to protect your parts’ surface, durable, and rust-resistant, and improve the appearance of sheet metal parts. At Xinprototype, surface treatments that meet the end-use metal parts’ needs.

as machined sheet metal prototype

As Machined

The surface of the sheet metal parts is like the raw material itself. Just cutting or bending with the shape. Suitable for internal or non-cosmetic parts.

anodizing sheet metal

Anodizing

Protect the surface, scratch-resistant, and available in multiple colors. Many of consumer electronics and housing sheet metal parts choose anodizing as the surface treatments.

powder coated sheet metal panels in black finish

Powder Coating

Popular in industrial enclosures and outdoor equipment due to its durability, wear-resistance, and corrosion-resistance. Regular color black, grey, and white, and available custom colors.

Custom painted sheet metal parts with matte finish

Painting

Support custom color or painting according to your Panton code. Smooth touch and cosmetic appearance. The appearance has matte, semi-gloss, and gloss finish options.

plating sheet metal

Plating

Steel parts with zinc plating for rust prevention. Most of the time, brass or copper parts will be electroplated with nickel or tin to protect the surface and also maintain the conductivity.

polishing sheet metal

Polishing

Creates a mirror-like surface that highlights the quality of your products, making it look precise and luxurious. Parts with high appearance requirements will choose this kind of surface treatment.

Other Available Finishes:

Brushing for directional metallic texture. Clear alodine for corrosion resistance. Sandblasting for silver matte finish. Passivation and black oxide for steel corrosion resistance. Silk screening-printing for logos and label marks. Laser Engraving for permanent markings for logos and labels. If you don’t find the surface in this list, contact us immediately. We provide custom surface treatments as per your requirements.

Sheet Metal Fabrication Solutions

From one-piece prototype to low-volume production, Xinprototype provides multiple processes to fit your project demand at different stages. In here, you’ll find out a reliable partner for custom sheet metal parts.

laser cutting sheet metal parts

Laser Cutting

A flat metal sheet has the same thickness and can be cut to any complex contours. No MOQ, no molds. Custom sheet metal components as per your drawings.Suitable for sheet parts with many of holes, irregular edges, or any shapes cut in the same plate.

CNC bending sheet metal box enclosure

CNC Bending

Provide the possibility to produce precision metal parts of complex enclosures. This is one of the main processes of sheet metal manufacturing. Multiple bends on a single metal part, to create 3D shapes like a ladder, a cover, and box enclosures. The part of the size range from small 5mm up to 2800mm.

Sheet metal prototyping for design validation

Sheet Metal Prototyping

In the early stage, requesting 1–20 metal parts is used as a prototype to test the design or trial assembly. 5–8 days fast production time, quickly validate results, and evaluate projects. Using the same materials as the final production, the prototype has the same appearance and properties.

Low-volume sheet metal production parts

Low-Volume Sheet Metal

Batch production without the stamping tool. The sheet metal manufacturing parts are suitable for direct use as finished products. 2-4 weeks leading time.Ideal for 50–10,000 pieces projects, where without tooling investment, and expect to keep parts quality are consistent.
