Finishing – Mechanical

In addition to our anodizing and other chemical finishing services, we offer mechanical finishing, such as buffing, brushing, bead blasting and tumbling. Each finishing technique generates different types of surface textures – from rough or patterned to a mirror finish.

If your product design requires a final surface finish, improved surface quality, or to prepare for various final cosmetic finishes, consider the following types of mechanical finishes to enhance your products look and feel.

Buffing

After extruding your components, we can create this attractive cosmetic surface finish that replicates polished chrome.

Brushing/Sanding

This finish is cosmetically appealing and looks like stainless steel. Brushing/sanding is beneficial for blending extruded die lines and covering imperfections. It is available in a wide range of textures. This secondary operation provides a perfect solution to your aluminum extrusion surface finish needs.

Bead Blasting

Bead blasting produces a unique granular appearance and comes in a range of textures. We work closely with a partner supplier to perform this operation for you, further simplifying supply chain management.

Tumbling

A tumbled finish on your components  shows a galvanized appearance. The degree of shine, spangled, or matte grey appearance, however, depends on the type of media (abrasive material) and the amount of tumbling time used.

There are a variety of tumbling media available, including ceramic, plastic, or synthetic media. Different media will have a different affect on the finished look and feel of your components.

We can tumble your entire part to eliminate swirl marks that occur from normal end-brush deburring machines. Tumbling also eliminates flow lines from the extrusion process. This type of mechanical finishing can serve multiple purposes such as deburring, washing, and polishing.
