Sheet metal working in perfection and variety
Parts made of thin sheet are like a business card for your products. Whether as modern and functionally designed design elements of machine cladding or as important technical components, which must fulfill the highest characteristics of clock frequency and wear resistance.
Our modern and automated sheet metal fabrication, combined with the right surface treatment, will make a significant contribution to your customers' love to work with their products daily. Our sheet metal specialists will gladly advise you in order to get the best out of the high-tech sheet metal product together with you.

From prototypes to series of tens of thousands, we manufacture everything on our Trumpf laser systems. By combining punching and laser processes on one machine, we can reduce the throughput time for demanding parts to a minimum.
Here are some highlights that inspire:
- Fully automatic Stopa sheet metal warehouse with up to 300 storage spaces
- Processing of metal sheets up to large format (1'500x3'000 mm)
- Numerous alloys and sheet thicknesses always in stock, reserved for your express orders
- Laser processing up to material thickness of 25 mm
- Expertise in machining structural steel, stainless steel, aluminum and copper alloys
- Laser cutting, punching, bending and tapping, all in one production process!
- On our list of machines in the download area you will find many additional information about laser and punching. For all further information, we look forward to your call.


For cylindrical shapes, we have various round and profile rolling mills available, where we can bring both flat sheets and profile bars in all materials quickly in shape and the desired length.
Internally we can roll in the following dimension, for larger dimensions we have external partners:
Profiles: 15 mm thick and 100 mm wide
Sheets: 15 mm thick and 1'800 mm wide
Mostly these parts go directly into the further processing by welding or mechanical processing.

You want both small and medium series and large quantities ready to install from a single source? No problem, on our stamping machines we produce series of up to several hundred thousand pieces per year and undertake the complete post-processing, such as trowelling and surface treatments. You can benefit from our decades of experience in stamped parts production and enjoy the following services:
- Advice on the structural design of the stamped and bent parts
- Advice on the choice of materials and the surface treatment
- Express production of prototypes and sample series
- Tool design and manufacturing (everything in-house)
- Heat treatment such as solution annealing, nitrocarburizing or hardening
- Surface treatments such as silvering, gold plating, etc.
- Picking and just-in-time delivery


Our 230-ton CNC press brakes quickly and accurately shape even the toughest materials up to 3'000 mm in length.
Efficient software integration enables us to optimally shorten set-up times and bending times.
With the SPI Sheetmetal Data Editor we are able to simulate the bending processes already in the CAD system and provide you with optimal advice during the design phase.

No compromises are made in terms of surface quality. With visible parts we guarantee a 100% scratch-free surface, so that the parts can be used without painting. We achieve this by using foiled metal sheets or where this is not possible by means of subsequent grinding and polishing processes.
Trowalisieren
In our own Trowalisieranlage we are able to remove by means of vibratory grinding sharp edges, oil and solvent from the parts surface and prepare them for the further process steps. This method is particularly suitable for smaller stampings with various bends and complex geometries.
Grinding master
With our surface grinding system, we give your products the desired finish and perfect surface finish. Depending on the requirements, various sanding belts and polishing wheels are used, which can be converted within a very short time.

Cladding for special printing press
With Aartech, the customer has found the ideal partner for the highly complex production of moldings for the graphics industry.
The flawless surface of the shuttering is just as challenging as the tight manufacturing tolerances.
In addition, specially designed packaging ensures that the components can be transported between the individual manufacturing processes right through to the customer without damage or contamination.


Extractors for laser systems
Extractors are used in flatbed lasers for the rapid removal of process exhaust gases.
We manufacture extensive sheet metal assemblies for the market leader in the field of laser systems and deliver them just-in-time to the customer's respective assembly plants in Switzerland and abroad.
Our services start with the engineering of sheet metal assemblies, flat machining, folding, assembly of mechanical and pneumatic components up to the provision of export packaging.
