Metal Finishing Services

Alongside manufacturing parts and components in-house, we can also apply a range of coatings to the finished products to protect them against the elements, make them more hard-wearing, or more aesthetically pleasing.

Anodizing Treatment

Anodizing is the process of creating a strong, protective layer on finished CNC machined parts by immersing them in a conductive solution and using a high voltage to achieve the desired layer thickness to increase the durability of the parts (as well as achieve aesthetic benefits). Weimi offers various types of anodizing including sulfuric acid anodization 5-20 microns thick (to increase strength), chromic acid anodization 2-5 microns thick (to improve appearance), and oxalic acid anodizing up to 60 microns thick (to improve corrosion resistance and provide electrical insulation), hard anodizing 250-300 microns thick (to improve wearability), and porcelain anodizing 6-20 microns thick (to improve surface texture).

Brushing, Polishing & Sandblasting Services

Alongside the anodizing treatment, we can provide a number of different decorative surface finishes including high shine, straight-line brushing, random brushing, corrugated brushing, and rotary (radial) brushing. Sometimes we may also recommend sandblasting and polishing prior to anodizing to improve surface texture for optimum results and prolonged wearability.

Black Oxide Coating Finish

It is common to apply a black chemical coating surface treatment to improve rust prevention as the oxide film on the metal surface can isolate air from the material and prolong its lifespan. The black coating treatment usually takes around 40-80 minutes (depending on the size of the item being coated) and uses high heat to achieve a matte or silk finish with a light sheen.

Electroplating Treatment

At Weimi, we have over 15 years of experience in manufacturing and we’ve perfected our electroplating methods to ensure a smooth and flawless finish, every time. We offer the following electroplating and surface treatments: zinc plating / galvanising (for rust prevention), nickel plating (both electroplated and electroless nickel plating), chrome plating (for hardness and heat resistance), titanium plating, vacuum coating, copper and precious metal plating, and more.

Silkscreen Printing

Silkscreen processing technology allows us to create opaque, long-lasting prints such as logos, text, colourful patterns, and more on machined parts. The process supports a large range of colours and shades, so you will not be limited in your designs in any way! While designs can be simply decorative, we can also use this method to provide instructions or warnings on mechanical parts and components. All printed content has good resistance to sunlight, acids, and alkalis, as well as being eco-friendly.

Surface Spraying Treatment

In order to extend the longevity of products that will be exposed to the elements, we recommend powder spraying the components and parts to protect them from sunlight, rain, and wear. Electrostatic spraying (also known as powder spraying) can produce a thick 100-300 micron coating with just one spray (unlike conventional methods that produce this result after 4-6 coats). The spray gives a protective, corrosion-resistant layer to metal surfaces and Weimi’s unique process ensures all unused powder can be 98% recycled, making our treatments environmentally-cautious.
