Product development
It makes no difference if you only have a preliminary idea, a sketch, or complete production drawings – our design engineers are capable of assisting with the design or modification of part or the entire construction, so that the final product fulfils the functional and aesthetic requirements at an affordable production cost. We will design and prepare all the required work accessories if necessary.
-
Product development
- Our product development is based entirely on 3D models. All materials used in the product’s composition, work operations and quality requirements are described in detail in the product’s composition notes, which ensures the required initial data for on-time and quality production in the future.
-
3D DesignWe use the Solidedge software and are able to read and process all files in the .stp format.
-
Technology developmentWe have developed technology that ensures we meet the required quality standard at the planned production quantities with the lowest possible costs.
-
Preparing, controlling and testing samplesWe will compile measurement protocols and conduct the functional and endurance tests of a component or product, if required.
-
Tools
- Metec has its own unit for designing and constructing tools as well as jigs. The unit permits establishing new products quicker and at a lower cost as well as ensuring a smoother production process in the future. More information about our tool production competences can be found here: link to tool production reference products
Component production
Tarmetec has the skills and the equipment for component production to specification using various laser cutting, forming, and cutting technologies.
-
Tube detail production
- One of our strengths is the production of tube components. The preparation of preforms takes place using a fully automatic laser cutting machine. The bending of tubes can be done using various bending machines with different characteristics. There are also different types of technological equipment used for processing tube ends.
-
LasercuttingWe cut work-pieces with the maximum diameter of 150 mm, wall thickness of 5 mm and length of up to 5.0 m.
-
BendingWe bend pipes of 12–80 mm in all kinds of radii, including a variable radius.
-
RollingWe achieve large bending radii of components on the pipe rolling machine. The maximum pipe diameter is 80 mm.
-
Finishing of pipe endsWe can widen and compress the pipe ends or otherwise shape them to join the pipes with other structural elements as required.
-
Sheet detail production
- We offer the choice between laser cutting technology and forming for preparing the preforms. The decision is made based on the complexity and quantity. The appropriate way to give details of a three-dimensional shape is a choice between a universal bending press or a specially prepared bending tool. The existence of different technologies for removing production waste, processing openings or threading is self-explanatory.
-
Laser cuttingWe cut regular and stainless steel and aluminium up to 15 mm. The maximum capacity of our fibre lasers is 6 kW.
-
FormingWe have several press brakes with the compressive force of 25–1,000 tonnes for manufacturing component work-pieces needed in larger quantities.
-
DeburringWe deburr work-pieces with special tools or equipment.
-
BendingFor bending operations, we can use sheet press brakes with a length of up to 3 m and compressive force of 200 t, as well as universal press press brakes with the compressive force of up to 1,000 t.
-
Machining
- Metec CNC, the daughter company of the Metec group, has several turning and milling machines with up to 5 axles for manufacturing different components or the post-processing of assemblies. We also have universal milling, turning and polishing machines for manufacturing components with smaller requirements. Additional information about machining can be found on the Metec CNC website (link).
Welding
We weld various types of non-alloy steel, stainless steel, and aluminium. We use manual arc welding stations, semi-automatic systems as well as multi-headed welding robots. The company is recognised as a certified provider of welding tasks according to the ISO 3834 – 2 standard.
-

Turning
Our production floor includes 13 turning benches, allowing for the manufacture of components with a maximum diameter of 350mm and a length of 600mm. The tool clip can be pre-loaded with up to 24 different cutting instruments, half of which also include either rotating or live instruments. Half of our turning benches have dual spindles (incl. those with dual spindles and dual tool clips), which allows a component to be worked on from two different sides without removing it from the machine and without interrupting the operator.
-
Turning
-
Turning bench for small-batch productionPrototypes and small batches are produced on our cycle-programmed turning bench.
-
Single-spindle turning benchTo ensure faster cycle times, we have developed many specialised solutions for attaching components in order to significantly reduce the standby time of our machines in between work cycles.
-
Dual-spindle turning benchThe horizontal production centre can operate two different components simultaneously and up to 24 different tools can be arranged in advance.
-
Milling
Our production floor has 7 milling benches that can process components up to a size of 1500 x 700 x 500mm. The tool clip can be pre-loaded with up to 30 different cutting instruments. While using different turntables, components can also be turned along an axis during processing, that is, they can be tilted.
-
Milling
-
Milling benchThe tool clip can hold up to 30 tools.
-
5-axis guided production centreThe technological apex of milling benches features 5 simultaneously guidable moving axes.
-
Finishing and assembling
We have a wide range of different technologies at our disposal that give stainless steel and ferrous metal products the required aesthetical appearance and corrosion protection.
-
Surface finishing
- Surface finishing is usually one of the last work procedures before the final assembly of the product. There is a great danger of damaging components while in transport. Components must be packaged very carefully and stored is such a way so that they do not damage one another. These activities involve additional monetary expenses. Metec has therefore created its own surface finishing capacity and placed the unit immediately preceding the final assembly line to keep better control over the costs and quality of the process.
-
Electro polishingWe carry out electrochemical polishing of stainless steel components and assemblies with the maximum dimensions of 1.0 x 1.0 x 4.0 m.
-
EtchingIn acid baths, we process structures within the maximum dimensions of 3.0 x 1.0 x 1.0 m.
-
Shot peening of stainless steelWe automatically shot-peen stainless-steel components and structures with stainless steel shots to remove corrosive parts or layers and to improve their visual appearance. The maximum dimensions of structures are 1.0 x 1.0 x 2.0 m.
-
Shot peening of steelAutomatic steel shot peening is used to remove dross, rust and other oxidized layers from the surface of steel products to ensure better paint adhesion and corrosion protection. The maximum dimensions of structures are 1.3 x 1.3 x 2.5 m.
-
Mechanical grinding and polishingBy mechanical grinding or polishing, we give stainless-steel structures the required appearance.
-
Galvanised surface finishingWe commission our collaborative partners to perform galvanic coatings.
-
Powder coatingOur coating line consists of 3-level pretreatment (neutral dipping, degreasing and protective Qxcilan layer) and the coating area, where we can process components with the maximum dimensions of 1.2 x 2.0 x 3.0 m.
-
Wet paintingWe are able to wet-paint structures with a maximum length of 3 m and a weight of 500 kg. To prepare component surfaces, we use a 3-level pretreatment on the powder-coating line.
-
Assembling
- We assemble and perform the end-product functional testing for mechanical, hydraulic, and electronic components (also including ESD).
-
Mechanical assemblyWe carry out the mechanical assembly of both stainless steel and ferrous metal structures.
-
Assembly of electrical componentsWe install electrical components and connect them with wiring. We ensure that static electricity does not damage the components. We conduct a functional final review to ensure that all driving gears, light fittings and control packages are in working order.
-
Assembly of hydraulic and pneumatic componentsThe composition of many of the products we manufacture also include hydraulic and pneumatic components We install the assemblies and check their operability
Control and logistics
80% of the products prepared by Metec are final products, which means they are not prepared as inputs for other production companies but are ready for final use. Under these circumstances, there are no final external quality checks on the quality of our work, which means there is a heightened demand on our internal control procedures. The client can choose delivery of goods to their central warehouse or directly to other locations throughout the world.
-
Quality control
- The production process undergoes quality control from the moment the purchased components arrive. We register all cases of non-conformity in the different production process stages. We are then capable of establishing the more critical process parts and can direct more control resources into the problematic sections. We will perform as agreed with the client for specified operations or the final product 100% control according to an established methodology.
-
Measurement laboratoryWe have numerous fully digital and programmable measuring devices and equipment for inspecting components or products with different accuracy classes and sizes. All measuring devices are calibrated on a regular basis.
-
LaserscannerWe are able to create a realistic 3D image of the ready-made product and compare it to a computer-generated model.
-
Functional final control70% of our production includes final products, i.e. products ready for package removal and for use by the end-user. Therefore, we check the working order of all product functions before issuing them from the factory.
-
Logistics
- We have good cooperation partners whose assistance we can use to find the most suitable means according to speed and cost for sending different quantities of products to every corner of the world.
