Problems solved by technology

[0002] In the prior art, the conventional steps of making leather embossed boards are as follows: 1. Computer scans the leather-like pattern; 2. Then the film is released; 3. Spray the photosensitive liquid on the steel plate and take it to the photosensitive frame for photosensitization; 4. Wash the pattern with God's water; 5. Corrode the pattern with nitric acid; 6. Polish and polish; 7. Send a layer of hard chrome plating, and the embossed board is finished. The disadvantage of this method is that the pattern of the embossed board is Straight, without radians, it is difficult to make several different depth patterns on the same steel plate, because it needs to use corrosive chemicals. Therefore, it is not safe and environmentally friendly to use this method to make embossed plates

Embodiment Construction

[0013] Provided is a method for making a leather mold embossed board, the method comprising the steps of:

[0014] 1) Scan the skin sample with a laser three-dimensional copying machine to obtain the unit pattern of the skin sample. The unit pattern can generally be 1-500 square millimeters in size.

[0015] 2) Input the scanned data into the computer, and use the program in the computer to process the scanned pattern into a program that can be output to drive the engraving machine;

[0016] 3) Use the processed computer program to drive the computer engraving machine to carve leather-like patterns on the acrylic board;

[0017] 4) According to the ratio of adding 5-20 grams of silicone oil per 100 grams of silicone rubber, and 1-10 grams of coagulation water per 100 grams of silicone rubber, pour the silicone rubber with better fluidity on the acrylic plate with the pattern carved. According to the size of the embossed board area, one or several pieces of silicone molds with...

Abstract

The process of making embossing plate of leather mold includes the following steps: obtaining the leather sample pattern with one laser copying machine and treating the scanned pattern in a computer to obtain program for driving engraving machine; carving the pattern on an acryl plate with a computerized engraving machine; pouring silica gel with added 5-20 wt% silicone oil onto the acryl plate to obtain silica gel mold; coating the mold with 1000-3000 mesh silver powder and setting in a electrolytic bath to plate copper for 1-5 days so as to make copper plate with the corresponding pattern; combining the copper plate onto steel plate in the same size with molten tin; polishing and cleaning the copper plate; and plating one layer of hard chromium to make the embossing plate. The process is simple and can make high quality embossing plate.

Description

technical field [0001] The invention relates to a leather mold embossed board, in particular to a method for making a leather mold embossed board. Background technique [0002] In the prior art, the conventional steps of making leather embossed boards are as follows: 1. Computer scans the leather-like pattern; 2. Then the film is released; 3. Spray the photosensitive liquid on the steel plate and take it to the photosensitive frame for photosensitization; 4. Wash the pattern with God's water; 5. Corrode the pattern with nitric acid; 6. Polish and polish; 7. Send a layer of hard chrome plating, and the embossed board is finished. The disadvantage of this method is that the pattern of the embossed board is Straight, without radians, it is difficult to make several patterns with different depths on the same steel plate, because corrosive chemicals are required, so it is not safe and environmentally friendly to make embossed plates by this method.
