Sheet metal forming allows for making more or less complicated subassemblies or complete mechanical casings, from sheets of various thicknesses, of different types, depending on the purpose, operating conditions or construction assumptions. It is possible to apply one or several technologies using dedicated machines, tools and instruments. In justified cases, it is possible to combine several types of materials together.
We have machines and competences that allow us to make use of the following technologies as part of sheet metal forming: cutting, laser cutting and punching, sheet metal bending, spot welding, PEM assembly, fusion welding, riveting and thread forming.
After sheet metal forming, we can perform powder coating and applying inscription.
In addition, we offer galvanizing and multi-colour anodizing, chemical treatment of stainless steel sheets (etching, glass blasting, electro-grinding) and engraving of inscriptions.
Examples of solutions
Mounting brackets are functional and useful retail equipment. They are used to mount devices used by the cashier such as a monitor, a fiscal printer, or a payment terminal.
They are made from precision steel piping, steel sheet, and plastic connectors using laser cutting, bending, milling, and powder coating. The final assembly and picking take place on an assembly line. Assembled and complete brackets are packed and dispatched to customers. Thanks to the brackets, all devices are kept in one place in locations convenient for both the cashier and the customer. They improve working comfort and ergonomics. They can be delivered in any custom configuration selected from several sizes. You can pick the right monitor, printer, or terminal bracket and other equipment.
Audio valve amplifier
A professional, valve, stereo audio amplifier. High-quality materials were used in its production.
The casing is made from chromium-nickel sheets and tube, using the technology of: laser cutting, plasma welding and proper surface grinding, welding or pressing of PEM’s for fixing electronics. The casing also contains turned and milled elements, which were made in accordance with the assumptions of the visual design.
The electronic subassemblies have been assembled and soldered manually to minimize acoustic interference. Testing and tuning was performed using professional music modules generating analogue signals. The final technical acceptance was carried out in a professional listening room on the premises of the company.
Made of the appropriate class of aluzinc steel sheet, with the use of: mechanical punching, edge bending on CNC controlled machines. Severe dimensional tolerances and durability and stability of the entire structure were additionally ensured by instrumented bench work (including riveting).
Subassemblies of the casing of passenger information display panel
Made of hot-dip galvanized sheet, 2 mm thick and supplemented with PEM’s, using the following technology: laser cutting, edge bending, pressing PEM’s, riveting and powder coating. Maintaining dimensional tolerances of each of the mounting points of separate panels, with external dimensions of the panel ranging from 1000 to 2000 mm, was ensured by using special equipment. The casing was powder coated which ensures a smooth texture and resistance to external weather conditions in order to meet the aesthetic requirements of the casing.
Subassemblies for hanging the external LCD / LED display
Made of aluminium sheet 4 mm thick, using technology of: punching, edge bending and welding of reinforcements and brackets. Maintaining the dimensions and angle of bending at each point of each element over 2000 mm long and the strength of the connection of welded elements and pressed into the essential element was ensured. This is essential in the further assembly process with a given display screen. Resistance to various atmospheric conditions during operation is ensured by powder coating, with a powder paint appropriate for these conditions.
Brackets that fix LED display elements
Made of 5 mm thick aluminium sheet and pressed screws with metric thread of different diameters, using the following technology: laser cutting, bending, assembly of sleeves on eccentric presses and plasma welding of positioning brackets. They ensure a very strong connection and are additionally protected against adverse weather conditions by powder coating with appropriate paint.
Control panel of the AC/DC converter
Made of aluminium sheet 4 mm thick, using laser cutting technology and other edge and hole machining technologies: automatic milling, precise chamfering, threading, drilling. The appropriate visual effect was achieved by grinding of the panel surface and powder coating using a smooth paint.
Shielding covers – fixing of various PEM’s for assembly of electronics PCB’s
Made of chromium-nickel sheet metal and connection elements fastened with high precision. The following technologies were used: laser cutting, edge bending and assembly of connection elements. High accuracy and aesthetics were ensured. The presented fragment presents different methods and types of PEM’s.
Shields for electronics PCB’s
Made of chromium-nickel or aluminium sheet, using the technology of: laser cutting, edge bending, assembly of various pressed PEM’s, from different material. The material class of the PEM’s must be compatible with the class of the sheet for which is used. Resistance to very difficult operating conditions, protected with chrome hardening or electro-cut.
Made of hot-galvanized sheet steel, 2 mm thick, using the technology of: laser cutting, edge bending, gas welding and powder coating. Dimensional repeatability was achieved by using dedicated positioning devices for reinforcing brackets in the welding process and resistance to external atmospheric conditions through the use of a suitable powder paint.
