Metal Gathering Machines

Resistance Heating and Upsetting Machines are designed for use in drop forging and valve industry. Generally upsetting can be applied to almost any application calling for the gathering of stock material to enable a component to be produced with the minimum of press works. The perfect “grain-flow” obtained, together with extremely short heating times the upsetting machine is ideal for a variety of jobs and almost in all cases no external or additional heat is required for the subsequent forging operations.

These machines are employed for the production of a wide range of shapes and sizes such as formation of beads, bulbs, collars, stops and flanges on rods as well as tube stock as required in the manufacture of parts like valve heads, bolt heads, control rods, bobbins etc.

A typical application of this machine is to produce upset blanks for the subsequent manufacture of engine valves.
