For the food industry, we manufacture hermetically sealed housings that reliably protect sensitive electronics from water, cleaning agents, and aggressive chemicals.
Our laser welding processes produce pore-free, visually flawless seams that meet even the most demanding hygiene standards. Each assembly undergoes 100% leak testing to ensure safety and reliability. The design is specifically optimised for high-volume industrialisation, with an annual production output of around 12,000 units.
These high-precision carrier assemblies are used in semiconductor testing systems.
They consist of multiple layers that must be precisely aligned and perfectly flat to ensure reliable testing results. A spring layer provides secure mechanical fixation of the SMD components during operation. We employ laser precision cutting, laser welding, and laser marking (including DMC codes and serial numbers) to ensure maximum accuracy and full traceability. More than 30,000 units are produced annually in series production.
The stainless steel mechanical actuators we manufacture are used in SMD assembly systems and other precision equipment.
They must adhere to extremely tight tolerances and function reliably even at high cycle speeds. Using laser precision cutting, a process-stable bending process, laser welding and mechanical finishing, we ensure that the components are durable and precise. Series production comprises over 20,000 units per year.
For optical sensors, we manufacture precise, hermetically sealed assemblies that protect sensitive components while ensuring optimal optical transparency.
All laser weld seams are polished, and each housing undergoes 100% leak testing to guarantee integrity and performance. This process ensures reliable operation even under demanding conditions. Annual production exceeds 20,000 units.
The laser-welded copper contacts we produce ensure optimum conductivity and stable electrical connections.
Selective removal of the nickel layer achieves excellent weld seam quality, while heat generation for surrounding plastic parts remains minimal. Areas of application include battery controllers, power distribution units and energy systems. Series production comprises more than 5,000 units per year.
For a leading customer in the electronics industry, we manufacture around 20,000 fluid sensors each year. These components demand the highest precision and consistent quality. As a contract manufacturer, we handle the entire process chain — from pre-assembly of the sensors and housings to laser-based hermetic sealing and polishing of the weld seams.
The greatest challenge lies in processing the delicate sensor structures. The sensor housing has a diameter of only 6 mm. Our laser welding technology ensures not only a completely hermetic connection but also a uniform and visually appealing weld seam. Each sensor undergoes thorough visual and leak testing to guarantee flawless functionality and long-term reliability.
Cooling rib profiles are used in the electronics industry. With an annual production capacity of 1,000 units, the sophisticated aluminum assembly includes sawing, laser welding, machining and laser marking.
A special feature of our production process is the creation of a non-porous aluminum weld seam. This is crucial for the quality and reliability of the cooling rib profile. We meet the highest surface requirements, as the end product is a visible part for our customer.
In the production of stationary energy storage systems, we handle all steps of sheet metal and welded assembly manufacturing. Individual parts are produced through laser cutting, bending, and the pressing of standard components. These parts are then pre-assembled into welded subassemblies and prepared for the next step: welding the cell terminals.
To achieve optimal welding results, the cell terminals are laser-cleaned before the cell connectors are welded using laser technology. For each production batch, the weld seams undergo quality control through destructive metallographic testing. Subsequently, the complete welded subassembly is joined and assembled into a functional battery module. Finally, each battery module undergoes voltage and insulation testing to meet the highest safety and reliability standards.
The carrier assemblies for test systems are manufactured for the electronics industry. The production process starts with a 100% incoming goods inspection of the individual parts to ensure quality and compliance with the specifications. This is followed by the welding of the individual parts. We fulfil an annual volume of around 30,000 units.
To identify the products, we label each item with a DMC code and an item number. This is followed by a 100% outgoing goods inspection to ensure that each product meets the required quality standards.
Special features in the production of these carrier assemblies are the welding of several layers to form one component and the insertion of plastic layers between the sheets that must not be affected by the heat input when welding.
Our range of services for housings for electric motors includes various processes such as laser cutting and bending, heat conduction welding, pulsed welding, pickling and laser marking. The project also includes extensive process development, including a component design suitable for welding and various clamping concepts. We produce an annual volume of 20,000 units here.
One special feature: welding processes in the vicinity of electronic components require minimal heat input in order to avoid damaging the electronic components. The enclosures comply with protection class IP69K, which protects against the ingress of dust and water, even during high-pressure or steam jet cleaning.
Our services for optical apertures include various manufacturing processes, including laser welding, laser ablation, laser fine cutting and geometry measurement using a confocal microscope.
The optical apertures are specially developed for use in the electronics industry and have an annual volume of 650 units.
A special feature is the reduction of the starting material from 150 µm to a residual thickness of 25 µm. Depending on the specific product requirements of our customers, the removal can also be carried out as a bevel, whereby a thickness tolerance of +/- 3 µm is maintained.
Our services for the mechanical actuation systems include laser welding and a sophisticated clamping concept for positioning the spring. The annual production capacity in this product category is 80,000 units.
An integral part of our quality management process is the 100% inspection of the spring position using a camera system. This ensures that every product meets our strict quality requirements.
Our strengths here are the handling of particularly fine and difficult to access welding points as well as a precise procedure to optimally position the spring.
We produce around 4,000 flexible shims a year for our customers for use in the semiconductor industry. Our range of services includes laser fine cutting, chemical and mechanical processing and mechanical machining.
Flexible shims are characterized by precision in scaling. This also applies to a high length and width ratio, which enables flexible contour selection. We also offer our customers a wide range of materials. Shims can be manufactured in a thickness range from 0.01 to 2.00 mm.
