  • Publication number: 20250050563
    Abstract: A method for producing an object having a microstructure. In the production of the objects, use is made of injection molds which have a counterstructure to the desired microstructure of the object, wherein the counterstructure of the injection mold can be obtained by laser structuring. The material and the objects produced therefrom have proven to be surprisingly robust, hard-wearing and slip-resistant, making them particularly suitable for the production of handles for power tools. A material which includes at least one thermoplastic elastomer material, wherein a texture depth of the material is in a range of from 250 to 400 ?m, preferably in a range of from 300 to 380 ?m, and more preferably about 325 ?m. In yet another aspect, the invention relates to use of the material as a surface material for power tools.

  • Patent number: 11858109
    Abstract: Side handle for an electric hand-held power tool, wherein the side handle has a grip region designed to be gripped by a user, and a clamping unit, by which the side handle can be releasably fastened to a machine neck of the hand-held power tool, wherein the clamping unit has an operating element, by which the clamping unit is able to be clamped and unclamped, wherein the operating element, when the clamping unit is in the clamped state, is substantially flush with the surface of the grip region. The operating element is preferably in the form of a clamping lever.
