Abstract

The present invention relates to a manufacturing method of fan blade with wood texture. The method mainly includes the following processes: extrusion forming, trimming, heat transfer printing, coating and drying. The extrusion forming and trimming procedures are performed on a foaming plastic material with better ductility to obtain a rough plate (10). A rough plate is then placed on a displaceable transfer-printing platform (2). A wood texture on the transfer printing thin film (22) is pressed and printed on the rough plate (10) by a heated PU roller (21). The rough plate (10) with the wood texture on the surface is coated with UV clear lacquer and dried by the irradiation of a UV drier (4) to obtain the fan blade with wood texture.

Description

Type 1285706, cutting, and heat transfer have wood textures, and the first trees are used to destroy the application of wood because of the low naturalness. Therefore, the fan blades are for the real mode. Therefore, the skin is first, that is, The environmental protection of the slashing of the eucalyptus tree is directly limited by the wood chips and can not be applied to the wooden stickers. The technical field of the whole system is related to a method of making a fan blade with wood grain, printing, painting and baking. Dry production methods. Especially the hooligans and the design style of ordinary furniture, but more advocating the character of self-level furniture. In addition to some direct direct display of its wood grain processing, so that it can have the texture of the wood grain, there is a surface texture representation applied by the industry to various types of installations, thereby adding five, invention description (1) According to the invention, the invention adopts the method of pressing and extruding the fan blade [previously, according to the prior art, the texture of the present invention is a high-grade home, and the veneer can be directly coated, so that the texture on the same shape is only the skin with the missing shape. The use of the chopping source is the speed at which the trees should be planted, and the fan blades are placed on the large curvature. In addition, the surface of the manually operated blade is naturally protected by the restriction pattern forming technique. The balance of the speed of the trees to be protected. The technology of the work is the full application of the skin itself. The application of the skin to the movable wood veneer can cause the original and the system. In fact, the problem is caused by the fact that the wood is made. Therefore, it is not suitable for the current words. Therefore, there is still a need for it, and it is often necessary to neatly apply the time of the affixing and the production of wood grain. The use of wood veneer is the stage of planting the raw material of the wood. The plant is continued to be applied to the wind. Also
