Exterior décor panel for home appliance and apparatus of manufacturing the same

An exterior décor panel for a home appliance includes a metal sheet having a first surface and a second surface opposite the first surface. The metal sheet includes a first patterned portion having successive recesses formed in the first surface, where each of the successive recesses have a prescribed depth, and a second patterned portion having successive protrusions formed at the second surface, where the successive protrusions correspond to the successive recesses. The successive recesses are formed by applying a force to the first surface, thereby transferring the force to the second surface to form the successive protrusions.

Method for manufacturing a component of austenitic TWIP or TRIP/TWIP steel
11247252 · 2022-02-15 · ·

The present invention relates to a method for manufacturing a component of austenitic TWIP or TRIP/TWIP steel. A flat product (1) is deformed by achieving at least one indentation (16) on at least one surface of the flat product (1) in order to have in the deformed product (5) areas of a high strength steel embedded in a matrix of a ductile material. The invention also relates to the use of the component where areas of a high strength steel embedded in a matrix of a ductile material are required in the same component.

METHOD AND SYSTEM FOR VARYING THE GAGE OF METAL STRIPS

A variable thickness process and system for processing steel strips to obtain a profile with at least two different thicknesses along its width which includes at least one heating step, and at least one stretching step and one straightening step.

SURFACE TEXTURING OF DEFORMING TOOLS

A method of producing a deforming tool (2) having a structured embossing surface (4) which can be brought into contact with a surface of a substrate (1) for plastic deformation thereof (of the substrate), the method comprising: determining a target structure to be produced on the substrate (1); geometrically distorting the target structure, such that an “embossing image structure” is obtained; inverting the “embossing image structure”, such that the embossing structure for the embossed surface (4) is obtained; and producing the embossing surface (4) of the deforming tool (2) according to the embossing structure.

PROFILES

An elongate profile (1) having a first portion (2) and a second portion (3), the first and second portions (2, 3) being joined together at a first joining portion (JP1), the first and second portions (2, 3) being non collinear, the joining portion (JP1) comprising an array of raised or rebated formations (10a), each formation extending across the joining portion (JP1) in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive formations in an array (10A) and the pitch (P) between successive formations in an array being from 2 to 20 times, for example from 5 to 15 times, the thickness (G) of the flatlands.

Method for engraving aluminium surfaces

The invention relates to a method including very superficial embossing combined with superficial laminating, which involves a slight reduction in thickness, the method being applied to plates several millimetres thick and to aluminium sheets having a thickness of less than 0.3 mm, supplied, in either case, as independent plates or in a continuous roll.

EMBOSSING ROLL

An embossing roll (1) having a cylindrical surface (2) comprising a central portion (3) having an embossing pattern (10) and side portions (4a, 4b) arranged on each side of the central portion, which are free from embossing pattern, wherein circumferential buffer channels (5) are provided on each side of the central portion (3), between the central portion and the side portions, along the cylindrical surface (2) of the embossing roll.

Profiles

An elongate profile having a first portion and a second portion, the first and second portions being joined together at a first joining portion, the first and second portions being non collinear, the joining portion comprising an array of raised or rebated formations, each formation extending across the joining portion in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive formations in an array and the pitch between successive formations in an array being from 2 to 20 times, for example from 5 to 15 times, the thickness of the flatlands.

Method for obtaining a vertical or horizontal profiled element for the interconnection of plasterboard panels to walls and element obtained with such method
11761202 · 2023-09-19 · ·

A method for obtaining a vertical or horizontal profiled element for the interconnection of plasterboard panels to walls, in particular to plasterboard walls that can be applied to in-wall frames for retractable sliding doors or for the provision of drywall dividing walls. The method entails a continuous machining of a metallic lamina by punching or drawing or rolling obtained by using two rollers, one acting as a die and the other acting as a punch, so as to obtain on the metallic lamina a plurality of holes, which are uniformly distributed according to a series of mutually parallel rows.
