Embodiment Construction

[0067] exist figure 1 In , the calender 1 for embossing comprises an infrared heater 2 which softens the continuous sheet material 7, or at least softens its surface. The sheet material 7 may be a plastic sheet, or a sheet made of one or more materials other than plastic, coated with a plastic. Sheet materials may include, for example, metal, reinforced fibers, or fabrics. The softened or molten plastic surface of the sheet material is then embossed by means of tempered embossing rollers coated with metallic glass. The embossing roll interacts with the second roll 3, creating an opposing pressure 7 on the sheet material passing through the nip. The calendering unit 1 also includes a cooling roll 5 which cools the counter pressure roll 3 and a cooling roll 6 which cools the sheet material.

[0068] exist figure 2 , the forming tool 20 is in the form of a cylindrical work roll of a polymer processing unit, as for example in figure 1 as described in. The forming tool 20 in...

Abstract

A forming tool (20) characterised in that it comprises a substrate (21) and a metallic glass layer (23) on at least the working surface (22) of the forming tool (20) whereas the forming tool is one of: a) a forming tool of an extrusion press; b) a die of a wire-drawing machine; c) a roll of a polymer processing unit.

Description

technical field [0001] The present invention relates to a forming tool and a method of modifying the surface of a workpiece or ductile compound, wherein at least one surface of the workpiece or ductile compound is in contact with the surface of the forming tool at least once, and to A method of texturing (or forming a structure) the outer surface of a forming tool. Background technique [0002] There are many types of forming operations in the materials processing industry. For example, in the metal industry, forming operations may include: [0003] • Extrusion process, which is defined as the process of giving a shape to a material, such as aluminum, by forcing the material through shaped openings in a die. The extruded material is produced as an elongated piece having the same shape as the die opening. [0004] The drawing (or wire-drawing) process, which is a process of thinning metal in which a thin rod is pushed or pulled through a single die or through a series of s...
