Presses and automatic coil feeding lines
ROSTRA Stamping zajišťuje sériové lisování plechových dílů na klikových a výstředníkových lisech s lisovací silou od 50 do 800 tun.
Our production equipment can process parts of various sizes and shape complexity. For repeat series production we use automatic coil feeding lines that uncoil, straighten and precisely feed the sheet from the coil into the press tool.
Alongside automated stamping, we also use manual part loading, depending on the nature of the product.

50 tAlmost all presses have automatic coil feeding lines — a straightener with a coil holder that feeds directly into the press and advances the material in step with the stroke. The operator only changes the coil and monitors the process. The lines were purchased progressively in 2014, 2017, 2022 and 2023. The only press without a feeding line is reserved for a specific two-section tool where the operator inserts the stamping by hand.
Downstream operations
- Welding of automotive parts — our own certified welding cell since 2021
- Nut welding — technology introduced in 2008 for the PSA T75 project; we are preparing a new robotic welding cell with nut welding
- Marking laser (since 2023) — laser marking of tools and parts directly into the metal
- 3D measuring machine (since 2015) and mikroskop pro detailní kontrolu dílů
- 100% inspection of safety parts
Check our stamping capabilities
Enter the required press force, the press tool dimensions and the material feeding method. We will show you the presses that may match your requirements based on the technical parameters given.
Haven't found a suitable press?
The configurator result is indicative only. If you are not sure about the technical parameters or need an individual assessment, send us a drawing or technical specification.
Our process engineers will check whether it can be produced on our machinery.
Actual feasibility also depends on the tool design, the material, the dimensions and shape of the part, and the required production volume.
Send a technical enquiryFrom coil to stamping
See in 3D how a sheet-metal stamping is produced in a progressive press tool on an automatic line.
With each press stroke, operations take place simultaneously at the individual stations of the tool. The material passes through the stations one by one until the finished part is separated.
Diagram with an illustrative part. The animation shows the principle of stamping in a progressive tool. The actual arrangement of operations varies with the tool design and the part being produced.
- Coil and straightenerThe sheet is unwound from the coil, passes through the straightener, and the feeder advances it into the press tool in sync with the press stroke.
- PiercingIn the relevant station, holes are pierced according to the part design. The holes can also serve to guide the strip precisely in subsequent operations.
- Contour trimmingSuccessive cutting creates the required part outline. Depending on the tool design, the part remains attached to the strip until the final operation.
- BendingIn the bending stations, the sheet is formed into the required product geometry.
- Finished partIn the final station, the finished stamping is separated from the strip and moves on to further processing or inspection.
Quality under control at every stage of production
At ROSTRA Stamping, quality is part of the entire production process – from preparing and setting up the presses through series production to the final inspection of finished parts.
We produce components for the automotive industry, where precision, production repeatability and compliance with customer requirements are essential.
Precision measurement and modern metrology
To inspect the dimensions and geometry of stampings, we use 3D coordinate measuring machines, digital microscopes and other specialised measuring equipment.
The ROSTRA group's metrology equipment also includes an AI-assisted optical 3D scanner that enables non-contact measurement of complex shapes and comparison of the actual part geometry with the CAD model.
These technologies allow us to evaluate geometric deviations more accurately and verify that products conform to the technical documentation.
Inspection during series production
We do not check quality only at the start and end of production. We carry out inspections according to defined inspection procedures, capability analyses and regular product audits.
Process stability
We evaluate measurement results continuously. If we detect a deviation, we take action to keep the production process stable.
Quality is every employee's responsibility
The resulting quality is down not only to modern technology but above all to the experience and responsible approach of our employees.
From setters and press operators to process engineers and quality inspectors – everyone helps to ensure that our products meet the specified requirements.
