scope:

General

The requirements of this standard apply only to those horizontal hydraulically powered presses that extrude metals by means of applying sufficient pressure to an individual metal billet, confined within a container, to force the metal to be extruded through the configured openings of a die. The horizontal hydraulic extrusion press, hereafter referred to as a press, is a hydraulically powered machine that functions to extrude metals horizontally either by the direct or indirect process. It includes components necessary to handle and process metals from the loading mechanism through the platen exit or external butt shear. Components include control systems, hydraulic power systems, main force application cylinder and ram, auxiliary hydraulic and pneumatic cylinders that move components that are an integral part of the extruding machine, material loading mechanism, material pressure containment device, tooling used to apply forces to and form the material, tool handling equipment that function with the press operating cycle, shearing mechanisms, and process and equipment lubricating devices.

Exclusions

Specifically excluded from this standard are hydrostatic extrusion presses, vertical extrusion presses, laboratory presses used to develop extrusion techniques for new materials and products, and extruding machines of unconventional design.
