Sheet metal punching – efficient, precise and versatile

Punching is a key process in sheet metal working – wherever precise contours, high quantities and repeatable results are required. Special tools are used to punch, pierce or shape sheet metal to produce functional or ready-to-assemble parts.

At BVS Blechtechnik, punching is not just a classic manufacturing step – it is a highly efficient process that has been perfected through automated machines and tailor-made tool technology. Whether complex loudspeaker grilles with multiple perforations, gills, threaded passages or other functional elements: the benefit lies less in the number of units produced than in the cost-effectiveness of recurring geometries and special contours.

Advantages of punching at BVS:

High throughput thanks to short cycle times and modern machine technology
Cost-effective production of complex structures (e.g. slotted bridges or special contours)
Consistent results with minimal material loss
Optimised for series production, assemblies and system components

Depending on the component geometry, punching is used as a stand-alone process or in combination with other processes such as laser cutting or bending – for a result that is technically, economically and functionally impressive.

Stamped parts – precisely manufactured, versatile in application

Stamped parts are metal components that are produced by controlled punching or breaking through sheet metal – often in large quantities and with high repeat accuracy. They are used in a wide variety of industries, such as electrical engineering, medical technology, sensor technology and automotive engineering.

At BVS Blechtechnik, the quality of a stamped part begins with the selection of materials: sheets with thicknesses ranging from 0.5 to 3 mm are stamped, regardless of the material. Whether stainless steel, aluminium, steel or coated sheets – the decisive factors are the combination of the right tools, experience in process management and a clear understanding of the requirements for the component.

Even small differences make a big difference here:
✔ Minimal burr formation
✔ Warpage control
✔ Material-friendly punching
✔ Precise hole geometries
✔ Clean edges

Advantages and limitations of punching – and how BVS utilises it

Punching is one of the most efficient processes in sheet metal working – especially for series with recurring geometries. It enables:

✔ High cycle rates and short production times
✔ Low unit costs thanks to automated processes
✔ High precision and repeatability
✔ Option to combine with forming, threading or surface treatment

However, not every geometry can be punched. Very fine contours, extreme material thicknesses or variable individual pieces are often better achieved by laser cutting or a combination of both processes. BVS therefore analyses each project individually – and recommends the best solution in terms of both technology and economy.

Consistent quality – even with large quantities

When it comes to large series, it is not only speed that counts, but also reliability. That is why BVS uses a clearly defined quality system to ensure that every part is dimensionally accurate, functional and visually appealing:

Digital order control and seamless process documentation
Tool maintenance and regular inspection cycles
Integrated visual and dimensional inspections during production
Many years of experience in dealing with critical tolerances

The result: reliable quality from the first to the last component – with demonstrable advantages in terms of delivery time, costs and further processing.

FAQs about sheet metal punching at BVS Blechtechnik

For which applications is the punching process particularly suitable?

The punching process is ideal when precise holes, openings or special deformations need to be made in metal parts in a cost-effective manner. It is mainly used in series production with recurring geometries – for example, in housings, carrier plates or sheet metal parts for machine and equipment construction.

Which punching tools are used at BVS – and how flexible is the operation?

BVS uses high-quality standard punching tools that are individually adapted to the requirements of the component. For complex or non-standard geometries, several laser punching combination machines are also available, offering maximum flexibility in terms of shape, material and batch size.

How does BVS ensure that no undesirable deformations occur during punching?

Precise tool guidance, material-specific cutting parameters and continuous quality controls reduce deformation to a minimum. Each metal is processed with the appropriate punching tool – this ensures that dimensional stability is maintained even with thin sheets and filigree holes. Should warping and process-related deformation occur nonetheless, BVS is able to compensate for this through straightening operations.
