Problems solved by technology
The production method includes press molding and vacuum plasma sintering, the process conditions are complex, and the pressing process of the metal powder is easy to change the positional relationship of the metal material to be inlaid with respect to the blank, so that the effect of gold intercalation varies greatly between different batches of products. Therefore, it is not easy to control the product quality and reduce the qualified rate of the product

Abstract
The invention provides a metal working process. The metal working process comprises the steps that a metal sample is fixed to a blank and then subjected to sintering treatment to form a metal product.According to the metal working process, one metal product does not need to be subjected to grooving and inlaying processing to be combined with another metal product; and the blank containing metal particles and an organic binding agent is used as a substrate to fix the metal sample, and then the temperature of sintering treatment is controlled to be higher than the thermal decomposition temperature of the organic binding agent and lower than the critical melting temperature of the metal sample and the critical melting temperature of the metal particles, so that the metal product is obtainedafter the organic binding agent is removed through the sintering treatment. The working process is simplified. Meanwhile, as the organic binding agent in the blank is removed in the sintering treatment process, the binding force between the metal samples is enhanced in the gathering and binding process of the metal particles in the blank, and the percent of pass of products can be increased.
Description
technical field [0001] The invention relates to the technical field of metal processing, in particular to a metal processing technology. Background technique [0002] The interlaced gold process refers to the process of inlaying and firmly attaching metal materials on the surface of the utensils to make the surface smooth, and the boundary between the two materials is obvious and the texture is clear, so as to achieve a good interlaced gold effect. The traditional gold-staggered process is usually to embed the material into the surface of the pre-grooved utensils by forcing, extrusion, etc. In order to make the material and the utensils fit tightly and achieve a good gold-staggered effect, the processing technology is very high. . [0003] The Chinese patent application with the publication number CN110435346A discloses a method for making gold-silver craft ornaments. The method uses metal powder as the base material, puts the metal material to be inlaid in the metal powder...
