Emsil Group is capable of manufacturing complex products based on our Customer's drawings and specifications. Over the years we have expanded our capacities and capabilities into manufacturing most if not all process steps. Today, these capabilities allow us to manufacture turnkey projects at our 3 production sites and also provide additional services through our extensive network of collaborators. ​The industries in which we are active are: vacuum, energy, oil & gas, naval, aerospace and metallurgy. ​Types of products we manufacture Glass coaters and packaging machines in the vacuum industry Baseplates and chassis for the oil & gas and energy industries Winches and crane components for the naval industry Pressure vessels from carbon steel and stainless steel PROJECT MANAGEMENT DESIGN & ENGINEERING CUTTING ASSEMBLING & WELDING PRESS BREAKS FOR BENDING ROLLING MACHINING HEAT TREATMENT SURFACE TREATMENT FINAL ASSEMBLY & AUTOMATION CUSTOM PACKAGING & DISPATCH

By applying surface treatments on outer ring contact surfaces, it is possible to improve certain mechanical characteristics such as the hardness. By doing this, we can increase wear resistance while decreasing the friction coefficient. With certain treatments it is possible to achieve high resistance to specific chemical agents. The table below shows a small sample of examples of such surface treatments and their resulting technical characteristics.

Plasma systems from Diener electronic have long since established themselves in a wide range of industrial sectors. With the Tetra 45 low-pressure plasma system, you can rely on modern and future-proof cold plasma technology in a vacuum. The chamber volume of approx. 45 litres of this plasma system offers enough space to serve series production / automation. Low pressure plasma treatment is a proven technique for controlled ultra-fine cleaning, adhesion enhancement (activation and etching) and coating of thin films on substrate surfaces. Plasma is generated by applying high-frequency voltage in the vacuum chamber. In the process, the process gas introduced there is ionised. Fields of application: VOC-free cleaning of organic residues Activation before painting, gluing, potting, ... Etching of PTFE, photoresist, oxide layers, ... Super-hydrophobic and -hydrophilic coatings

Plasma systems from Diener electronic have long since established themselves in a wide variety of industrial sectors. With the PlasmaBeam DUO atmospheric pressure plasma system, you can rely on modern and future-proof plasma jet technology under atmospheric pressure. Due to the treatment width of 8 - 10 mm, substrates can be precisely treated locally. PlasmaBeam technology can be used for inline processes. With the help of robots, 2 or 3-dimensional surfaces can be treated. PlasmaBeam enables local surface cleaning without masking the rest of the surface. For example, cleaning before wire bonding and various processes in the electronics industry. Furthermore, the PlasmaBeam is suitable as a pre-treatment device for the following processes: Gluing, bonding, printing, laminating, soldering, welding, flocking. The following surfaces can be treated with PlasmaBeam: Plastics, rubber, metal, glass, ceramics, hybrid materials.
