Embodiment Construction

[0020] The present invention is described in further detail below.

[0021] The leather carving process includes the following steps:

[0022] Make corresponding convex and concave molds according to the selected pattern, and the convex and concave molds can be made of metal materials such as copper and iron;

[0023] The two-color PU leather with a temperature resistance of 120°C is selected. The two-color PU leather is purchased from Ningbo Comfort Company. It is a PU leather with one layer of light color and one layer of dark color. For example, two-color PU leather with dark background and light surface can be selected according to the pattern. Lay compound PVC on the back of PU leather, and punch it into semi-finished leather;

[0024] Preheat the punched semi-finished leather to 40-50°C with a heating plate;

[0025] Place the heated semi-finished leather on the punch and die;

[0026] Place the convex and concave dies in the hydraulic press for molding treatment. Th...

Abstract

The leather carving process includes the following steps: making convex-concave mold of the required patterns; adhering PVC layer to the back of two-color PU leatheret capable of resisting 120 deg.c temperature and cutting to the required size; heating the PU leatheret to 40-50 deg.c and setting on the convex-concave mold; mold pressurizing in a 5-10 ton press at 100-110 deg.c for 1-2 s; quick demolding; polishing to eliminate partial surface layer of the PU leatheret based on the pattern so as to form the color relief pattern. The said process can form two-color relief works with depth up to 20 mm.
