A can for packaging food, comprising a metal can body and a diaphragm lid (16) formed of lidding material which comprises a multilayer structure with at least an aluminum layer of from 6 to 90 microns thickness and a bond layer for fixing the lid (16) directly to the can body. One method for forming the can forms the lidding material by using an outwardly extending curl (20) at one end of the metal can body as the draw die. Lidding material which is carried by the body maker punch is drawn around the curl of the can body draw die so as to form the lidding material into a cup shape.

A manufacturing method of a member according to an aspect of the present invention is a manufacturing method of a member including a specific three-dimensional tubular portion, the manufacturing method including: a U-forming step of performing U-forming on metal material sheet using a U-forming die and punch including a U-forming punch to manufacture a U-formed article having a recessed cross-sectional shape; and an O-forming step of causing side end portions of the U-formed article to abut each other by an O-forming die to form abutting portions, in which a forming condition ratio a=Du/Do is set to 0.85 to 0.95.

This invention relates to a solenoid housing and to a method for providing a solenoid housing having the base, wall, center pole, and flange integrally connected as a single piece. The instant invention provides for mounting protrusions and window for electrical leads as an integral part of the housing and manufacturing process.

An apparatus for manufacturing a prismatic can includes a die configured to support a bar-shaped slug, a punch arranged on a horizontal axis of the die to reciprocate in a left and right direction so as to press the slug supported on the die, and a connecting rod between a driver configured to generate power and the punch to transmit the power generated by the driver to the punch. A cross-section of an edge of the punch in a direction of the die has a rectangular shape corresponding to a bottom surface of an impact can to be manufactured, and upper and lower areas of the punch are provided in an asymmetrical shape based on a horizontal axis center line.

An apparatus for forming and sealing an adjustable duct member for use in an air handling system. At least one work station accommodates a tapered work piece. A repositionable die is positioned relative to the work piece, and a cutting and forming assembly cooperates with the repositionable die to cut the work piece and form a coupling bead to reconnect the members together. A sealing assembly cooperates with the first repositioning die to seal the coupling bead in the first and second members. The work station includes an insertion channel having predetermined dimensions to accommodate at least a portion of the work piece. A clamping assembly is associated with the insertion channel to securely hold the tapered work piece at the predetermined position during the cutting and forming and sealing operations.
