A large bronze medal is a commemorative or artistic medal made primarily of copper.

1、 The production process of the large copper seal is as follows:

Design

Determine the theme: Determine the theme of the bronze medal according to the needs, such as historical events, cultural celebrities, natural scenery, etc.

Creative conception: Designers create creative ideas, draw sketches, consider the layout of patterns, color matching, three-dimensional sense, etc.

Computer drawing: Convert sketches into computer graphics for precise design and adjustment, ensuring the clarity and accuracy of patterns.

Carving mold

Making the original mold: Based on the design pattern, use carving tools to carve the original mold on the metal material. The quality of the original mold directly affects the final effect of the large copper seal, so experienced carvers are needed for fine production.

Remaking working mold: By using methods such as electroplating and die-casting, the original mold is transformed into a working mold. The working mold can be used multiple times for mass production of large copper stamps.

casting

Smelting copper material: Heating the copper material to a molten state to ensure the purity and fluidity of the copper liquid.

Casting molding: Pour the melted copper liquid into the working mold, wait for the copper liquid to cool and solidify, and then take out the preliminarily formed large copper seal.

Processing and processing

Polishing: Polish and polish the large copper seal to remove burrs and defects on the surface, making the seal surface smooth and flat, presenting a metallic luster.

Coloring treatment (optional): According to design requirements, the large copper seal can be colored, such as electroplating, baking paint, etc., to increase its artistic effect.

Quality inspection: Conduct strict quality inspection on the large copper seal to ensure that its size, pattern, quality, etc. meet the standard requirements.

2、 The characteristics of the large copper seal:

Thick Material: Large copper seals are usually made of thicker copper material, which has a certain sense of weight and gives people a calm and atmospheric feeling.

Exquisite craftsmanship: The production of large copper seals requires multiple complex processes, such as carving, casting, polishing, etc. Each process requires exquisite skills and strict quality control.

High artistic value: The design and production of large bronze plaques often incorporate elements of art, history, culture, etc., and have high artistic and collectible value.

Strong commemorative significance: The large bronze medal can serve as a carrier to commemorate major events, figures, or activities, and has strong commemorative significance.
