General principle of forging

Forging is a massive forming process; the temperature of the workpiece is increased to such an extent that the deformation forces required are considerably less than would be needed to cold work it. The two most important forging processes are open-die forging (in which forming of the workpiece takes place locally and mostly using simple dies) and

Greenwashing vs Green Cycling

Every step of what we do involves the emission of CO2. Today more than ever before, the “carbon footprints” of products and services are right at the top of the priority agenda. In principle a good development, but there’s more to the matter here: the responsible handling of all natural resources. Ever more urgency can be heard, also on the

Guideline for a typical melt treatment

Melt treatment for a hypoeutectic AlSi alloy for the production of high quality castings: Melt charge (ingots or mixture of ingots and in-house scrap) Check temperature of melt Carry out deoxidation using suitable salt mixtures Take samples for analysis (spectrometry) Correct magnesium content Carry out grain refinement using TiB Carry out

General information about machining

The term machinability covers those properties that influence metal shaping processes that involve chip formation. The important machining techniques for processing aluminium-based materials can be divided into machining with geometrically defined cutting edges (turning, milling or drilling), machining with non-geometrically defined cutting edges
