Our fiber laser makes us competitive and efficient in the market due to its flexibility and high quality processing method. The machine cuts formats up to 3000 x 1500 mm, max 20 mm in carbon steel and 20 mm in stainless steel.

The technology offers incredible possibilities in terms of design, capacity and material selection. Laser technology is also capable of cutting shapes and forms that no other method could achieve.

Laser cutting is used for both thin and thick materials. The advantage of using laser technology for cutting thin and hard materials is that there is no risk of the material breaking under the pressure of punching tools.

With laser cutting, it’s much easier to cut straight, fine lines and complex contours. The technology is capable of rapid changeovers or dimensional changes, making production very flexible. The material does not need to be reworked, which saves a lot of time, and because the cut is narrow, no expensive metal is lost.

In conclusion, laser cutting provides speed and high precision.

Punching

Forming, threading and some bending

Punching is a method of making holes in relatively thin material. A tool (punch) with the desired shape of the hole is pushed through the material under counter-holding pressure from a die. The punch and die have ground edges with the same contour as the punched object, which ensures that no breakage occurs around the cut surface.

Our punching machine provides a very high process speed and the processing time is very short. The machine offers extremely fast punching and the possibility to shape, thread or perform some bending. Material thickness processed is up to 4 mm in stainless steel and up to 8 mm in carbon steel and aluminium.

Edge pressing

Edge pressing is the method mainly used when forming sheet metal parts, as this technique is designed specifically for thin metals. The technique is also called edge bending and is a subcategory of bending – one of modern industry’s most widespread and flexible techniques for bending metals of all kinds into all kinds of shapes. Thanks to the adaptation of this technology to thin sheet metal parts, the flexible design of the sheet metal can now be fully exploited.

Materials
Steel, aluminium and galvanised steel
Max part size
H1300 × L2000 × W600 mm

Our powder plant is equipped with an advanced pre-treatment to provide state-of-the-art rust protection. The products are treated with Oxsilan for the best possible corrosion protection with a much lower environmental impact.

As a partner to several large industries, both in Sweden and abroad, Preform AB has specialised in powder coating that can meet high demands.

Our finishing facility has a 5-step wash and a modern Wagner paint booth, offering high flexibility, fast colour changes and short set-up times. We coat steel, aluminium and galvanised steel. Of course, the surface treatment is chrome-free.

If your product requires a different type of coating, e.g. zinc coating, we also arrange this through our partners.
