Surface refinement

In the modern metalworking industry, surface finishing plays a decisive role in not only making products aesthetically pleasing, but also increasing their functionality and durability. Whether for industrial applications, architecture or consumer goods, high-quality surface finishing is a must.

Why is surface refinement important?
Metals are naturally susceptible to corrosion and mechanical wear. A professional surface finish protects the material from environmental influences such as moisture, chemicals or UV radiation. It also improves electrical conductivity, heat dissipation and can improve friction properties, depending on the process chosen.

Surface finishing: What techniques do we offer?

Wet grinding
Wet grinding involves combining an abrasive with a special grinding fluid. This reduces heat development and minimises the risk of material deformation and grinding burn. This process is particularly suitable for the finest surface finishes and polished finishes.

Dry grinding
In dry grinding, the abrasive is used without liquid. This method is generally more efficient and quicker when removing coarse irregularities or old coatings. This procedure is often used for preparatory work before more detailed post-processing is carried out.

Deburring
Deburring involves removing sharp edges, burrs and unevenness that can occur during cutting, punching or milling. It not only improves the aesthetics of the parts, but also prevents injuries and improves the functionality and durability of the products. There are different deburring techniques depending on the material, size and shape of the workpiece and the specific requirements of the end product.

Powder coating
A ‘colour powder’ is applied electrostatically to the metal and then baked at a high temperature. This process is environmentally friendly and offers a wide range of colours and surface effects.
Advantages: Durability – Aesthetics – Functionality

What options do our surface systems offer?

Our services as an integrated system provider also include a broad spectrum of surface finishing. Decorative sanding takes place on our dry sanding machine or our wet sanding machines after the sheet metal parts have been punched or lasered. Depending on the desired surface structure and specified surface standard, we select the appropriate grit sizes of the grinding belts. We round off any sharp edges on our deburring machines. In between, we degrease and clean possible residues on the fully automatic pre-treatment plant, where the parts are simultaneously given corrosion protection.

The sheet metal parts receive a “fresh” paint on the fully automatic powder coating line. Whether for protection, refinement or as a design element, with the huge selection of RAL, NCS or special colours, the products shine in a high-quality look and colour scheme. First, ferrous metals are pre-treated by means of iron phosphating. Aluminium parts pass through the bath for pickling degreasing. The chemical baths are dosed automatically and are therefore constant, which is regularly checked by our painters. After rinsing, dripping, no-rinse coating (a colourless passivation) and drying of the adhesive water, the actual powder coating takes place. Using self-teaching programming, the painting robots apply the required amount of powder evenly to the workpieces. For smaller quantities, our specialists take the spraying process into their own hands.

Finally the baking in the oven takes place. Depending on the powder used (smooth, fine or coarse-structured powder), the metal now has a surface that not only looks good, but is also protected from the weather and is impact and scratch-resistant.

With individual external refinements, your housings or components get that special touch. We print your logo, descriptions, design elements and necessary inscriptions on your products using the screen printing process. You provide us with your printing data, and we create the screen printing film and the negative stencil for the screen. Our experienced staff manually ducks the ordered markings on all surfaces (powder coated, painted, anodized, chromated, ground or raw material).
