Custom-made products need manufacturing that can fully take the client's requirements into consideration, with technological capacities that can ensure the freedom of creativity and economy. When these conditions meet with the highest expertise of the employees in respect of the work processes, such as welding or pre-assembly, this will result in a value added that will have a truly durable value in the market. It is such a manufacturing that you can find at STAKOTRA, regardless at which premises the production takes place. Certain elements of the manufacturing process can be found at both premises without any limitation.
Blasting / preparing
Depending on the depth of processing, basically all raw materials (sheet, profile, pipe) are cleaned of dirt, rust and all pollution by an automatic blasting equipment.
We have all the necessary machinery to perform cutting of the raw materials. Cutting torches and plasma cutting tables, cold cutting saws for cutting profiles and special CNC-controlled cutting torches for 3D shaping of pipe ends with preparation for weld.
We can roll, arch and bend sheets, profiles and pipes. Our specialty is 3D bending of pipes, which is essential for the manufacturing of track for roller coasters.
The fitting of products starts with the basis. That is why we use precision fitting tables and equipment in our plants. It is only in this way that we can produce large components with very tight limits of tolerance.
Welding is unquestionably one of our strengths and will remain to be so. The faultless welding of geometrically complicated components with dynamic load, with a very high demand of precision and in various material qualities, is performed practically as an artistic performance. Doing the appropriate non-destructive tests in-house is almost self-evident.
We are able to perform machining of products of up to 50 tons per piece and achieve the tolerances required by our clients. We have several horizontal machining equipment (max. size/piece: 14,500x2,900x1,600), vertical lathes (max. size/piece: D7,000x2,900) as well as smaller auxiliary machines.
Direct blasting before painting is performed in special booths manually. We can achieve in this way SA 2.5 surface cleanness level and the paint adhesion specified by our clients which we apply on the surface using airless technology. Our own paintshops can be heated, of course, and comply in all respects with the relevant environment protection regulations.
We often produce complicated pieces, which would be too risky to deliver without test assembly. Or, in other cases, it is much more economical to perform assembly on the site of installation if certain larger parts are already assembled and even tested in our plant environment. For such operations, we have several assembly halls, including one, which is 120 m long and has an inner height of 12 m.
packing / loading
The usual method of packing is wooden pallet and plastic strapping. But special pieces often need special packing. So we also regularly pack components in containers and in vacuum foil. For smaller components of high value, we make wooden boxes.
Transportation takes place on public roads in 90%, from the manufacturing facility to the final destination (motorways are within 2 km from our plants), but we have already arranged ship transportation on the Danube to Hamburg. If necessary, we can also deliver our products by rail.
