Surface Finishing Treatment for both Metal & Plastic Parts

Surface Finishing Treatment

Surface finishing refers to different processes used to alter the surface of a manufactured product to give it a distinct or desired look and feel. Different techniques are used to improve the appearance, adherence, solderability, resistance to corrosion, hardness, conductivity and many other characteristics of industrial components.

3Q Machining offers a high quality surface finishing service for all components and parts regardless of the machining method used in producing them. We have some skilled experts who only handle finishing assignments so the quality of work done on your products is of exceptional quality. If you desire a perfect finish for your prototypes and other manufactured components get in touch with our customer services team for a quick and accurate quotation.

What surface finishings are Available?

aluminium as machined

As Machined / As Milled

The original finish left on the part by CNC machining is called the “as machined surface”. After simple deburring treatment, small processing lines can be seen with the naked eye, but it still has a smooth touch. If surface roughness is Ra/RMS 125, additional finishing can be done to reduce roughness at an added cost. Increasing the surface finish requirement to 63, 32 or 16 RMS will add cost as the feed rate may need to be reduced or additional post-processing may be required. 

As Machined surfaces provide the best dimensional accuracy and are the first choice for parts with tight tolerances.

Sand Blasting

Sandblasting is a reductive surface treatment in which a pressurized gun fires a stream of abrasive glass beads at the part to remove thin layers of the surface. This process creates a consistent matte/sand finish on the part and is often used to remove knife marks or imperfections. If your part has features that require tight tolerances on parts of the surface, mask off surfaces or holes that do not require blasting before blasting.

Titanium CNC Machining

High gloss mirror polishing

Sanding & polishing is one of the most common finish for prototyping. Sanding is very basic process to remove cutting marks or the printing marks, in order to get smooth surface. Get ready for further finish such as sandblasted, painted, chromed…

Started from rough sand paper, when you reach 2000 sand paper the part surface are smooth enough for high gloss polishing to obtain shiny surface or mirror look, transparent such as light guide, lens.

Painting

Painting is a very flexible way to create a different surface appearance.

We can achieve:
Matt or Glossy Texture; Soft Touch ( Rubber painting)
