Additional services and operations

Time and cost savings? Having bending and additional processes carried out by one party, saves valuable time and transport costs. It also means that curved constructions and/or semi-finished products delivered by Kersten Europe are ready to construct (install).

This means Kersten Europe is able to provide a total concept, from custom advice to engineering, prototyping and compiling a curved construction.

Kersten Europe works efficiently: for example, by carrying out everything under one roof, limiting residual materials to a minimum and saving on time and costs with the deployment of an off-line programming system.

Plate cutting

Cutting out sheet cut-outs

Gross plates are first cut to size and then rolled or set.  We cut sheets in various alloys with a surface of up to 16 x 4.5 meters and a thickness of 250 mm. The cutting is done on our cutting machines which are equipped with oxy fuel and plasma burners. The rotating 3D cutting head, if desired, applies complex welding edges in a uniform movement.

We aim to divide the gross sheet material as efficiently as possible, and if possible, making multiple unfolded patterns from one gross sheet. This restricts the number of residual materials to a minimum. Our engineers calculate exactly how much material is needed, taking into account any excess length.

(3D contour) cut to size

After the products are curved, any excess length is removed using robot technology. These advanced robots realize (complex) 3D contours and/or bevels in the same movement. Holes and cut-outs can also be cut. This highly accurate process results in significant cost savings compared to conventional techniques. Off-line programming makes it ideal for small and medium series.

As well as 3D cutting of cylinders, cones, tubes and pipes, our robots make complex cuts in profiles such as IPEs, HEAs and UNPs. For custom cutting of stainless steel, Kersten Europe uses advanced plasma and autogenous cutting robots.

Drilling and milling

Save time and money by performing both bending and machining under one roof. For mechanical processing, we use modern CNC technology for things such as drilling and milling.

Welding procedures

Welding is carried out by a team of experienced, certified welders using modern welding equipment. This ensures the best end result. Kersten Europe expertly performs welding activities on ferrous and non-ferrous alloys, varying from a simple longitudinal seam to a complete welded construction, including bottoms and accessories. It is also possible to have the activities inspected by a specialized body for being destructive (DO) or non-destructive (NDT).
