Deposition molded product, deposition molding method, and deposition molding apparatus

Abstract

A lamp (1) is produced by a first injection step of molding a lamp body (2) and a lens part (3) using a movable mold (9) and a stationary mold (10), a deposition step for deposition to form a film (2b) on the lamp body (2), and a second injection step of integrating the lamp body (2) and the lens part (3) with the aid of a resin material (6). In this case, an electrical connection site between a bulb (4) and a terminal (5) is masked without using any specialty masking material. A bulb (4) is incorporated in a step between the first injection step and the deposition step, and, in this incorporated state, deposition is carried out, whereby a film (4c) is formed on the surface of the front end of the bulb (4) and a part hidden behind the film (4c) is masked to ensure electrical insulation.

Description

technical field [0001] The present invention relates to the technical field of a film-forming molded body, a film-forming method, and a film-forming apparatus used for lamp bodies and signs for vehicles. Background technique [0002] Generally, in such a film-forming molded article, for example, there is a molded article such as a vehicle sign plate, which is coated on the surface of the member with a material having an effect such as a coloring effect or a reflection effect, and improves its pattern design performance. As a manufacturing method, for example, there is a method in which the surface of the formed component is coated with a decorative chrome plating film (for example, refer to Patent Document 1). [0003] However, at present, hexavalent chromium used in electroplating is a substance harmful to the human body and causes a problem of public nuisance due to environmental pollution, so it is subject to regulation, and dechromation is required. [0004] As a counte...

Problems solved by technology

[0005] However, in this technique, after the injection-molded base material is taken out from the injection molding device, it is placed in a vacuum evaporation device to form a film, and then, after the film-formed base material is taken out of the vacuum evaporation device, it is set in a In the injection molding device, the injection molding of the resin material on the film-forming surface requires a large number of processes, labor and time, and not only poor work efficiency, but also in the process of taking out, setting, and transporting from one device to another. On the surface to be filmed, and then increase scratches or dust on the surface that has been filmed, or the hands will touch the surface and adhere to oil stains. For these reasons, it is impossible to manufacture the expected film-formed product, and there is a risk of causing defects. products, the problem of poor yield
