In a method for the further processing of a product (30) that is preferably prefabricated in large numbers, the product has a surface (31) for an additive multi-dimensional application of material. Information for the additive multi-dimensional application of material is input into a device in which the multi-dimensional application of material is digitised from this information and is deconstructed into elements that are suitable for the additive application of the application of material to the surface (31). The prefabricated product (30) is introduced into a device (I) for additive application of the material application such that the elements for the additive multi-dimensional application of material on the surface (31) are assembled in accordance with the information using an additive manufacturing method. Because the surface is an individualising surface (31) of the prefabricated product, and because the additive application of material is a multi-dimensional individualisation that is intended and suitable for individualising the product, and because at least one of the prefabricated products is identified by the information and is provided individually with the multi-dimensional individualisation (32), a method is provided by which products that are prefabricated in relatively large numbers can be further processed, individualised or personalised to meet individual demands. The prefabricated product (30) is equipped with an associated information carrier for receiving the information for individualisation that supports the method sequence.

In some embodiments, a tool includes, in an injection molding machine, a movable internal core configured to receive a molded plastic layer thereon, the molded plastic layer having a thickness. The tool also comprises an injection nozzle configured to inject plastic material over the movable internal core to form the molded plastic layer; an ejection plate connected to the movable internal core; and multiple, movable support plates each having a thickness. The multiple, movable support plates are located behind the ejection plate. A movable support plate of the multiple, movable support plates is configured to determine the thickness of the molded plastic layer.

A method of manufacturing a doorstep or a door scuff is provided. The method includes an ABS material injection step of injecting an acrylonitrile butadiene styrene (ABS) material to have a doorstep (or a door scuff) shape; a plastic plating step of plating an ABS material with plastic; and a PP injection step of fixing the ABS material plated with plastic in a mold, and injecting PP to the ABS material fixed in the mold so that the ABS material and a polypropylene (PP) material have a one-piece structure.

In a method for producing a resin molded body, a thermosetting resin member is formed by heating a thermosetting resin material that is a raw material of the thermosetting resin member to complete a curing. A nascent surface having a functional group is formed on at least a part of a sealed surface of the thermosetting resin member by removing a surface layer that is an outermost layer of the sealed surface via irradiation of laser light to the sealed surface. The sealed surface of the thermosetting resin member is sealed with the thermoplastic resin member by injecting a thermoplastic resin material to the thermosetting resin member having the nascent surface, the functional group of the nascent surface being chemically bonded to the functional group of the additive. The thermosetting resin member has an absorption of the laser light at or above 10% per 1 m.

The present application provides a functional key assembly with symbol showing function and its manufacturing method. Specifically, in this application, the symbol of the functional key is provided on the inner surface of the function showing component or outer protective plate, to eliminate the provision of the parting line. Being manufactured by over-injection molding, the protective plate is provided with a carved structure at its inner portion and a back component at its lower portion such that the image of the symbol of the function key is cast onto the surface of the protective plate through the carved structure in backlit environment and is invisible without back lit, immerging effect is thus achieved, as a result of which, the armrest plate is therefore artistically decorated and less costly to manufacture at the same time.
