A manufacturing method of a plate member, in which a strip material can be positioned with respect to a die all through stamping operations using a pilot hole formed in an initial phase of the stamping operations. The plate member is manufactured by a press machine in which a progressive stamping die having a plurality of stations is placed. The manufacturing method comprises: forming an oval pilot hole 14 in an uncoiled strip 13; and stamping the uncoiled strip 13 by a plurality of operations while bringing a pilot pin 17 into contact with an inner edge of the pilot hole 14 at the operation before the pilot hole 14 is displaced, and at the operation after the pilot hole 14 is displaced.

A frypot of a commercial deep fat fryer includes a foam deck and a front wall that is a downward extending vertical face of the frypot. The foam deck and the front wall are formed by sheet metal that has a radius bend between the foam deck of the frypot and the front wall. The radius has a bend radius of between 0.25 inches and 1.5 inches.

A sound-absorbing non-combustible ceiling material and a method for manufacturing the same are disclosed. The method (S100) for manufacturing the sound-absorbing non-combustible ceiling material installed in a ceiling of a building includes a panel processing step (S1000) of processing each of a first panel including a metal and a second panel absorbing a sound wave; and a panel attaching step (S2000) of attaching the first panel and the second panel. The first panel includes a plurality of openings, and the first panel and the second panel are coupled by an adhesive layer to form the sound-absorbing non-combustible ceiling material.

A press ram for a fine blanking press comprises a ram plate section configured to carry a fine blanking tool and at least two guide sections positioned on opposing sides of the ram plate section. The ram plate section comprises an upper surface, a lower surface, and two opposing side surfaces. The at least two guide sections of the ram plate section are configured to guide movement of the press ram relative to a press frame during a fine blanking process. The at least two guide sections extend in a vertical direction to a level that is higher than the upper side of the ram plate section.

A method for optimising an energy-absorbing strap includes the steps of: (1) producing a single metal sheet, including a first connecting portion, for connecting to one of a support bracket and a fixed part of a vehicle, and a second connecting portion, for connecting to the other of the support bracket and the fixed part of the vehicle; and (2) producing a weakening in the single metal sheet to separate the first connecting portion from a tearable portion; bending a portion of the single metal sheet to produce a bent portion that interconnects the second connecting portion and the tearable portion, the second portion being bent back around in relation to the tearable portion; wherein the steps are selected to produce a desired energy-absorbance profile.
