Fill alloy - Import export

The bending of aluminum profiles used in curtain wall systems is carried out with a patented system by filling with a special alloy. During this process, the cross section is not only calendered with millimetric precision, but it also meets all the perpendicular tolerances, avoiding any kind of deformity deflection or "twisted effect", thus maintaining the perfect geometry required.

In the metal industry, die-casting is a manufacturing process of high precision. After heating to a liquid state, the alloys are filled mechanically and under high pressure into a steel form. At DGS Druckguss Systeme AG, the common metal alloys are aluminium and magnesium. The process is used for the production of great quantities of the same part (serial production) which are constant in shape and with a refined surface finish. In the die-casting process, it is possible to realize a mass production very economically and with high dimensional accuracy. In 1910, casting of the metals lead, zinc and tin became common in Europe. This manufacturing process became known in America under the name of “injection casting”. More and more the term was substituted with “die-casting”. The first production companies in Switzerland were Injecta in Teufenthal in 1920 and Bühler in 1925, which has now become DGS Druckguss Systeme AG. Since then, the process has been developed continually to constantl
