Method for printing patterns on outer surface of cookware

Abstract

The invention relates to a method for printing patterns on the outer surface of an aluminum cooker. The method comprises the steps as follows: carrying out sand blasting fluffing, cleaning, drying, primer coating and drying on the outer surface of a flat cooker blank, printing a designed pattern on a primer, carrying out high temperature drying and cooling, then covering the surface with pattern with a plastic film, forming with a mold, removing the laminated film on the formed cooker blank, coating celluloid paint, then drying, and finally milling the mouth and mounting a handle. According to the method, a manner of firstly printing and then forming is adopted, so that the patterns can continuously and integrally cover the side wall and the corners of the cooker and the outer surface of the cooker bottom, and the defects of a conventional process of firstly forming and then printing patterns that patterns on the side wall and the bottom of the cooker are printed separately, only simple patterns can be printed and curved surfaces of the corners cannot be printed are overcome; due to the automated, digital, direct spraying and orientated process, complex procedures of plate making, plate burning and multiple times of topping are omitted, and multicolor patterns and patterns with transition colors and gradient ramp can all be printed; and the method has the characteristics of being simple in operation, high in printing speed, high in production efficiency and good in pattern quality.

Description

technical field [0001] The invention belongs to the technical field of pattern printing on the outer surface of metal pans, in particular to a method for printing patterns on the outer surface of aluminum pans. Background technique [0002] At present, the methods of printing decorative patterns on the outer surface of metal pots and pans in China can be divided into two categories according to the process, screen printing process and transfer printing process. Screen printing: It is a kind of stencil printing, and the plate is made according to the pattern requirements. When printing, the special ink is placed on the surface of the plate, and through a certain pressure, the ink penetrates out of the holes of the plate and adheres to the surface of the product to form the required pattern or text. The screen printing process is the oldest printing process, which is only suitable for flat areas and simple patterns, and multi-color or complex patterns cannot be operated. Tra...

Problems solved by technology

Compared with the screen printing process, this process can print complex patterns but is only suitable for flat areas. It cannot be printed on the arc corners of the pot, and cannot achieve the effect of continuous patterns covering the entire outer surface, and basically relies on manual work. Operation, high skill requirements for operators, unstable quality, very low efficiency and high cost
