A processing method of vacuum forming for leather products comprises: step 1, making mold; step 2, heating raw materials of the leather products to a specified temperature, putting on surface of the mold, staying in vacuum forming conditions, and forming patterns on surfaces of the raw materials of the leather products, the patterns being corresponding to those on the surface of the mold; and step 3, cooling the raw materials of the leather products, and molding into the leather products for later use, wherein the specified temperature is 150-200 DEG C, the vacuum forming conditions are a vacuum degree range between 350-700 mmHg. According to the invention, the method is simple in technology, molds are convenient to prepare, products can be molded for one time, simulation of finished products is strong, and production efficiency is high.

In the leather (5) used to cover the shift handle (1), at the small rigid part with small bending rigidity formed along the end edge (21) of the leather material (20), the back side of the leather material (20) The leather material (20) is folded back in contact with each other to form an overlapping portion (9).

A method of manufacturing a phylactery, the method including providing an initial stage phylactery workpiece formed of animal skin, cutting the initial stage phylactery workpiece to define a second stage phylactery workpiece, the cutting including forming at least outline cut lines, interior cut lines and incised lines, and folding the second stage phylactery workpiece along at least some of the incised lines to define the phylactery.

The invention relates to a method for preparing a leather watch strap, comprising the following steps: providing a leather product body; sequentially soaking the leather product body in a first treatment agent and a second treatment agent for ultrasonic treatment; and soaking the leather product body The leather product body is dried to obtain the leather product; wherein, the first treatment agent is a fluoroacrylate compound with a relative molecular weight of 200-400; the second treatment agent is a fluorocarbon-based trialkoxysilane , the relative molecular weight is 500-800. The invention discloses a leather watch strap and a watch. In the preparation method of the present invention, a structurally complete protective layer is formed on the surface of the leather product body, so that the leather product has good water resistance and has excellent antifouling, weather resistance, friction resistance, deodorization and self-cleaning properties.

An interior trim panel for a vehicle includes a leather layer defining a feature having a radius of less than five millimeters, and a backing layer adhered to the leather layer and providing a support structure for the leather layer. A method of forming the interior trim panel includes clamping the leather layer in a frame to securely fix the edges of the leather layer, positioning the leather layer between compression mold dies defining a complementary surface having a feature with a radius of less than five millimeters, and compressing the leather layer between the dies.

The invention discloses a single-formwork button making machine which comprises a mainframe. The mainframe comprises a punch and a fixing frame, wherein the punch is installed on a machine head, and the fixing frame is installed on an X-axis moving frame and a Y-axis moving frame and located below the punch. A working table top is positioned below the fixing frame. A bottom module for being matched with the punch is arranged at the position of the working table top corresponding to the punch. The bottom module is provided with a foot curling bottom die for curling fastener paw parts is arranged on the bottom module, and the fixing frame is provided with a locating hole for locating and fixing a formwork module. Modified parts of the single-formwork button making machine are fewer, and compared with a newly developed button making machine, the single-formwork button making machine greatly reduces cost, saves time and is simple to operate. After the combination with a matched formwork, production efficiency is greatly improved, the fastener position error is 0.1 mm, fasteners are fixed firmly and are vertical and uniform in attitude, the paw parts of fasteners are just completely embedded in leather, the tail ends of paws are fully curled, and the pass rate is almost 100%. A die is provided with 1200-1400 fasteners, and the fasteners can be made in only 5 minutes.

The invention discloses a vacuum adsorption molding method for realizing continuous production, which aims to improve vacuum adsorption molding production efficiency. In the method, a baking station and a molding station are separately arranged to form double stations; and rear-section leather can be heated at the same time when front-section leather is molded so as to realize the continuous production and avoid the problem that a single station of conventional vacuum adsorption methods makes sheet heating and vacuum molding required to be sequentially performed to cause a relatively longer period. The method has the advantages of greatly shortening a molding period and improving molding efficiency.

The invention discloses a method for shaping a case, with the combination of fore-and-aft shaping and lateral shaping, the bottom-case and one lateral of the box being an integral body, and the other three laterals of the box being an integral body. With a method of combining fore-and-aft shaping with lateral shaping, the center of the box is stable and it is not inclined to overturn, which reduces the accidental destruction; the integral fast degree of the case is increased; the external volume of the case is decreased; and it is beautiful.
