Backward Extrusion

แปลว่า(english) Forcing metal to flow in a direction opposite to the motion of a punch or die.

Butt end

แปลว่า(english) The residual portion of an extrusion billet that is not forced through the die at the end of the extrusion cycle.

Billet container

แปลว่า(english) The part of the extrusion press into which the billet to be extruded is placed.

Bolster (die block)

แปลว่า(english) A “tool” or reinforcing part which supports the backer-which, in turn, supports an extruding die against the pressure of extrusion.

BACK-UP RING

แปลว่า(english) A fabric or plastic device that is used with an o-ring or other gasket to prevent extrusion of the o-ring or gasket into an adjacent space or crevice

Billet 2

แปลว่า(english) A solid semi-finished round or square product that has been hot worked by forging, rolling, or extrusion. An iron or steel billet has a minimum width or thickness of 1 1/2 in. and the cross-sectional area varies from 2 1/4 to 36 sq. in. For nonferrous metals, it may also be a casting suitable for finished or semi-finished rolling or for extrusion.

Backer (back-up plate)

แปลว่า(english) A “tool” or reinforcing part, which presses against the outer surface of an extrusion die, supporting it against the pressure of the extruding metal. The backer has an opening larger than the die aperture, allowing the extruded product to emerge without marring its soft surface.

Billet

แปลว่า(english) (1) A semi-finished section hot rolled from a metal ingot, with a rectangular cross section usually ranging from 16 to 36 in., the width being less than twice the thickness. Where the cross section exceeds 36 in., the term “bloom” is properly but not universally used. Sizes smaller than 16 in. are usually termed “bars”; a solid semi-finished round or square product which has been hot worked by forging, rolling, or extrusion. (2) A semi-finished, cogged, hot rolled or continuous-cast metal product of uniform section, usually rectangular with radiused corners. Billets are relatively larger than bars.
