HOT FORMING/PRESSING

Hot forming is a process of sheet metal forming that is also known as hot stamping or press hardening. All forming processes run above the recrystallization temperature of the metal used. During the hot forming of the sheet metal, the material recovers and softens. This enables high equivalent strain despite low forming forces. With our furnaces, pressing machines and in-house made tooling we are able to press vessel heads and other 3D formed segments.

SPINNING

The method for producing the dished heads is either via a spinning process or pressing and flanging process (or a combination of the two) the steel disc is spun on a hydraulic lathe which is then pressed to a tool. The tool can be set to have both the knuckle and spherical radius.

WELD EDGE PREPARATION

Edge preparation consists of removing material along edges of metal surfaces. You must prepare edges for welding when parts and assemblies require certain strength. To achieve full welding penetration, you must cut the edges of the metal.

This is done by flame cutting, grinding or machining.

Size and shape of edge preparation or groove depends on what material is used and joint design.

SURFACE TREATMENTS

Several surface treatments are possible that alter the surface of a manufactured item to achieve a certain property. We can offer pickling, polishing and sandblasting. Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminum alloys. The process of polishing involves using an abrasive belt on the surface to change the finish of the metal. Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.
