DETAILED DESCRIPTION OF THE INVENTION

[0023] The detailed description of the invention is intended for purposes of illustration of the preferred embodiments of the invention only and is not intended to limit the scope of the disclosure.

[0024] The present invention relates to a production method of worktop (1) suitable for use in home appliances. The said worktop (1) is produced by means of melamine impregnated decorative paper covered plates, glass surface plates, fiberboard plates, epoxy surface plates, laminate covered plastic plates, high temperature-resistant plastic plate or melamine impregnated plastic plates. Single piece worktop (1) is produced by injection molding all required lateral surfaces (top surface and/or side surfaces and/or bottom surface) of plate suitable to the product type with or without a fitting.

[0025] In the present invention, composite, plastic, plastic-derived, glass, stone and similar one piece materials, melamine impregnated decorative paper covered plates, glass surface plates, fiberboard plates, epoxy surface plates, laminate covered plastic plates, high temperature-resistant plastic plates or melamine impregnated plastic plate and/or a combination thereof are used as a plate (2). The same plate (2) element can also be produced by performing plastic injection molding to the back portion of a melamine impregnated decorative paper.

[0026] At this stage, individual or combinations selected from the group of cross-linking agents suitable to the raw materials, maleic anhydride combinations, strength-increasing additives, thermoplastic elastomers, SBS (Styrene Butylene Styrene), SEBS (Styrene Ethylene Butylene

[0027] Styrene), maleic anhydride containing homo- and/or co- and/or terpolymers (polypropylene, ABS, polypropylene and ABS mixtures), adhesion-improving additives and cross-linking additives are used to improve adhesion quality of the raw material and provide a sufficient level of adhesion. This makes it possible to obtain a main body of plate (2) for the worktop (1) out of composite, plastic, plastic-derived, glass, stone and similar one piece materials, melamine impregnated decorative paper covered plates, glass surface plates, fiberboard plates, epoxy surface plates, laminate covered plastic plates, high temperature-resistant plastic plates or melamine impregnated plastic plate and/or a combination thereof. After creating the plate (2), worktop (1) frame (3) is injected to the edges of the plate (2). At this stage, two different processes can be applied to create a frame (3). The first process is based on the principle of taking the frame (3) out of injection together with the plate (2) without fittings. The other process is based on taking the frame (3) out of injection together with the plate (2) with fittings in a more ready-assembled manner. The method of the present invention, various injection molding processes can be applied to the frame (3) which can be produced by above two processes. Conventional injection molding, physical foaming (microcellular foam injection molding), chemical foam injection or a combination thereof can be applied. Microcellular foam injection molding is different from conventional plastic injection molding in that it expands microcells inside the plastic and provides up to 20% savings in weight in grams by reducing the density of plastic solution with homogenized supercritical fluid-gas mixture. In such injection applications, plastic materials including but not limited to polypropylenes, carbon fiber-reinforced polypropylenes, talk-reinforced polypropylenes, glass fiber-reinforced polypropylenes, ABS (Acrylonitrile Butadiene Styrene), carbon fiber-reinforced ABS, talk-reinforced ABS, glass fiber-reinforced ABS, polyester group polymers, PA 6, PA 6.6 and their carbon fibers, glass fiber and talk-reinforced structures, maleic anhydride containing homo- and/or co- and/or terpolymers or polymer mixtures (polypropylenes, ABS, polypropylene and ABS mixtures), maleic anhydride combinations, polycarbonate/ABS or a combination thereof are used. During injections, core and cavity molds are used. The said core and cavity molds help to produce the plate (2) in one piece and generate pressure output thanks to placement of the plate (2) and raw material flow. After the injection process, if required, laser and etching processes and also adhesion-improving operations can be performed on the surface of the worktop (1).
