[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0018] In response to the demand for handle or steering wheel covering, the designer of the present invention innovatively proposed an integrated bionic leather suede manufacturing process for the handle or steering wheel surface, which can integrally form a bionic leather suede texture layer during the foaming process, eliminating the covering process and effectively saving costs.
[0019] like Figure 1 and Figure 2As shown, a manufacturing process of an integrated bionic leather suede for a handle or a steering wheel surface in this embodiment includes the following steps:
[0020] Step 1: die-casting the skeleton, using the raw materials to die-cast the handle or steering wheel skeleton;
[0021] Step 2: foaming, placing the skeleton in step 1 in a foaming mold, wherein the surface of the mold cavity is photoetched with a bionic leather texture, and then injecting a foaming material into the mold, wherein the foaming material foams in the mold, and after the foaming is completed, a bionic leather texture layer is formed on the foamed surface of the skeleton;
[0022] Step three: assemble, take out the foamed frame and assemble it into a complete handle or steering wheel.
[0023] In the step 2, the surface of the mold cavity is photolithographically patterned with a bionic leather texture using a femtosecond technique or a picosecond technique of a photolithography machine.
[0024] The bionic leather texture includes a plurality of dense points with different depths and diameters, and the diameter of the dense points is greater than 50 nm.
[0025] The foaming material is AB material, TPE or silicone rubber.
[0026] The bionic leather texture processing technology on the mold cavity surface is as follows: step one, using 3D software programming to edit the texture according to the shape; step two, using a photolithography machine to perform a first texture processing on the mold cavity surface according to the texture in step one, with a processing depth of 0.004mm; step three, changing the processing depth to 0.002mm, and performing a second photolithography processing on the same area according to the same texture; step four, performing a third photolithography texture processing on the same area again according to the same texture, with a processing depth of 0.002mm. By performing three layers of progressive photolithography with the same texture but different depths, the bionic leather texture layer after foaming can be made more delicate.
[0027] The spot diameter of the photolithography machine is 1 um.
[0028] The present invention solves the defects existing in the background technology, and has the following beneficial effects: the present invention is an one-piece bionic suede manufacturing process for the surface of a handle or a steering wheel, through the bionic suede texture on the surface of the foaming mold cavity, and forms a bionic suede texture layer on the surface of the handle or steering wheel in an integrated manner during the foaming process, thereby increasing the feel of the handle or steering wheel, preventing slipping and cold, and replacing various genuine leather or leather outer layers covering the surface of the handle or steering wheel, while omitting the most complicated coating process, making the manufacturing process simpler, environmentally friendly and energy-saving, and reducing the cost of the entire process.
