Problems solved by technology

The problems of mosaic technology are: inlaying is manual operation, complicated operation, time-consuming and labor-intensive, and requires high professionalism of operators, so it is difficult to apply it quickly and on a large scale. In relation to the support strength, mosaic technology cannot be used
The electroplating process can achieve rapid and large-scale application, but it has the problems of high pollution and high energy consumption

Embodiment 1

[0034] A process for processing metal graphics and text on the surface of a metal handicraft, comprising the following steps:

[0035] (1) Firstly, use 3D drawing software to establish a spatial structural shape model, and use a 3D printer to print the model into a wax model. The thickness of the wax model is 0.5-1mm, preferably 0.6-0.8mm.

[0036] (2) Using metal powder paint as raw material, the pattern coating is partially processed on the surface of the wax model by spraying, cooled and solidified in an environment of 0°C, and the thickness of the pattern coating is 0.02-0.08mm. The metal powder coating is composed of copper powder (gold powder) and low-temperature wax (melting point at 55°C, commercially available) mixed in a volume ratio of 1.5:1. The low-temperature wax is heated and melted and mixed with copper powder to form a metal powder coating. Use while it is hot .

[0037] (3) Put the wax mold processed in step (2) into the mold cavity (such as a conventional r...

[0045] A process for processing metal graphics and text on the surface of a metal handicraft, comprising the following steps:

[0046](1) Firstly, use 3D drawing software to establish a spatial structural shape model, and use a 3D printer to print the model into a resin mold. The thickness of the resin model is 0.5-1mm, preferably 0.6-0.8mm.

[0047] (2) Using metal powder paint as raw material, the text coating is formed on the surface of the resin mold by hand-painting, cooled and solidified in an environment of 4°C, and the thickness of the text coating is 0.02-0.08mm. The metal powder coating is composed of gold powder and low-temperature wax (melting point at 65°C, commercially available) mixed at a volume ratio of 2:1. The low-temperature wax is heated and melted and mixed with gold powder to form a metal powder coating for use while it is hot.

[0048] (3) Put the resin mold processed in step (2) into the mold cavity (such as a conventional circular mold cavity) as an i...

Embodiment 3

[0056] A process for processing metal graphics and text on the surface of a metal handicraft, comprising the following steps:

[0057] (1) Firstly, use 3D drawing software to establish a spatial structural shape model, and use a 3D printer to print the model into a wax model. The thickness of the wax model is 0.5-1mm, preferably 0.6-0.8mm.

[0058] (2) Using metal powder paint as the raw material, the graphic coating (both pattern and text) is partially processed on the surface of the wax model by spraying, and cooled and solidified in an environment of 0°C. The thickness of the graphic coating is 0.02-0.08 mm. The metal powder coating is composed of copper powder and low-temperature wax (melting point at 60°C, commercially available) mixed in a volume ratio of 2:1. The low-temperature wax is heated and melted and mixed with copper powder to form a metal powder coating for use while it is hot.

[0059] (3) Put the wax-based or resin mold processed in step (2) as an inner mold...

Abstract

The invention discloses a process for processing metal graphics and text on the surface of a metal handicraft, which includes the following steps: (1) First, use three-dimensional modeling and 3D printing. (2) Using metal powder paint as raw material, spraying or hand-painting is used to process the graphic coating on the surface of the model, and then cool and solidify; (3) Put the model processed in step (2) into the mold cavity as an inner mold, Then pour gypsum slurry into the mold cavity, the gypsum slurry is naturally solidified to obtain a gypsum mold, and the gypsum mold is heated to remove the inner mold. (4) Directly pour the molten metal into the pouring port of the uncooled plaster mold, keep it for 3-8 minutes after the casting is completed, and then put it directly into the water to remove the plaster to obtain the product. The invention is relatively simple to operate, requires less professionalism of operators, has low energy consumption and less pollution, is also suitable for handicrafts with complicated shapes, and can be applied quickly and on a large scale.

Description

technical field [0001] The invention relates to the technical field of handicraft production, in particular to a process for processing metal graphics on the surface of metal handicrafts. Background technique [0002] Metal handicrafts are handicrafts made of gold, silver, copper, iron, tin and other metal materials, or mainly made of metal materials and supplemented by other materials. They have a thick, vigorous, luxurious, elegant and fine style. The earliest metal crafts in China are copper crafts unearthed from sites such as the Majiayao Culture, Dawenkou Culture and the later Qiaojia Culture in the middle Neolithic period. Gold handicrafts appeared in the Shang Dynasty. During the Warring States Period, there were handicrafts made by combining various metal materials and metal and non-metal materials (jade, colored glaze). The Han Dynasty was able to produce exquisite filigree weaving, stacking and inlay products. The Tang Dynasty was the heyday of metal handicrafts...
