• Electroplating

  The electroplating (also electroplating) is a process from surface and layer technology for electrochemical deposition of metals on metallic or metallized surfaces using an electrolyte and direct current. The galvanic coating usually serves to protect the workpieces from corrosion or to increase the wear resistance of their surface. The method is particularly often used for coating steels with metals of a suitable property profile. Such metallic coatings have a wide field of application since they obtain the metallic appearance of the workpieces and the electrical conductivity.

• Extrusion

  The extrusion is a forming process which is mainly used for thermoplastics. The plastic is pressed through a shaping opening as a viscous mass under high pressure and high temperature. Extrusion is one of the most widely used processes in the plastics processing industry and, thanks to its wide range of advantages in terms of efficiency, has gained great importance in the production of plastic parts. An extruder is used for extrusion, which is also referred to as a screw press. In principle, a distinction is made between the single-screw extruder and the twin-screw extruder.
