Embodiment Construction

[0077] exist Figure 1A A metal strip 1 is schematically shown in , which is divided into segments 2 indicated with dashed lines 3 . Dashed line 3 indicates a reference point placed on the strip. Furthermore, when cut from the strip, each segment 2 or blank is provided with a unique identification code to enable tracking of the segment 2 or blank both at the metal manufacturer and at the manufacturer of the product made from said blank.

[0078] A phantom representation of the product 4 to be made from the segment 2 is shown in the figure, in this case an exterior door panel for a vehicle.

[0079] In the enlarged view of section 2, the product is indicated with a dotted line representing the product after it has been formed from a blank, which is usually after it has been formed in a stamping device. Also shown schematically in the enlarged view are different textures applied to the surface of the blank, respectively texture 5 and texture 6, texture 5 being an optimized visu...

Abstract

The invention relates to a metal substrate provided with surface textures wherein different texture patterns are provided over predefined surface areas of the metal substrate and wherein the differenttexture patterns are tailored to predefined surface properties of a product which is to be made out of the metal substrate as well as to a method for applying such surface textures on the metal substrate.

Description

technical field [0001] The present invention relates to a metal substrate provided with a tailored surface texture, wherein the surface texture is tailored to predetermined surface characteristics of a product to be made from the metal substrate, and to a method for applying such a custom texture. Background technique [0002] In the finishing of (coated) metal strips, the metal strip is leveled and / or temper rolled. Leveling is used to control the shape and form of the strip, and temper rolling is used to improve the mechanical properties of the metal strip by elongating the strip. The surface quality of the strip is also improved in terms of appearance, surface texture and surface functionality (functionality). Using the temper rolling step, texture can be transferred from the work rolls to the surface of the strip for certain functions such as but not limited to metallic strip appearance, better adhesion of paint, tribological properties, and improved forming characteri...
