Herstellungs- und Dienstleistungenprogramm

Aluminium alloys are melted in gas and holding electric resistance furnaces. The aluminium alloy is modified and de-gased through FDU device in foundry. Piston casting is carried out through the gravity based casting into metal permanent moulds in a fully robotic casting machine and in a few mechanized casting machines. In the case of small-scale orders, piston casting takes place in the manually operated casting machines, as well. The requisite mechanical properties of piston castings are further attained either by a one-stage or two-stage heat treatment. Our piston machine shop is equipped with automatic and semi-automatic CNC machining lines. Their application guarantees the attainment of the required shapes and dimensions of the surface curve, piston pin hole and other main piston dimensions during the piston machining. The following types of piston surface finish are made by the company itself or in cooperation with external providers: * hard elox * phosphate coating * tin coating * surface sliding layer (on molybdenum basis)
