A foot gold case and its production method, and tables including the gold case

Abstract

The invention relates to a pure-gold watchcase manufacturing method, comprising raw material melting, rough blank forming, stamping treatment and cutting treatment. The invention also relates to a pure-gold watchcase obtained by the above method, and a dial plate comprising the pure-gold watchcase. The dial plate also comprises an inner container, a movement, a graduated disk, a watch glass, a watch crown and an ear part. The inner container comprises an inner container body and a fixed part. The pure-gold watchcase is wrapped at the outer wall of the inner container. The movement is arranged inside the inner container. The graduated disk is arranged on the top surface of the movement in a covering manner. The watch glass is disposed at an opening of the inner container in a covering manner. With the gold content higher than nine hundred and ninety per one thousand, the pure-gold watchcase achieves good machining performance, allows surface treatment, has high strength and hardness and is adapted to normal knock and collision when used. The rejection rate in the pure-gold watchcase manufacturing process is low, and the production efficiency is high. The dial plate comprising the pure-gold watchcase has good waterproofness, and the strength of an outer shell of the dial plate is further enhanced, so the service lifetime of the dial plate is prolonged.

Description

technical field [0001] The invention belongs to the field of watches, and in particular relates to a pure gold watch case, a manufacturing method thereof and a watch including the pure gold watch case. Background technique [0002] Gold is a precious metal with excellent corrosion resistance. It also has good ductility and malleability, and is easy to process, so it is often used to make jewelry. Gold watches have both the decoration of gold and the practicality of watches, and are gradually favored by more and more consumers. Pure gold is gold with a gold content of not less than 990‰, which has good fineness and high value. However, due to the softness of pure gold, it is easy to deform and damage during machining or assembly, resulting in scrap rates in the production process. High, surface polishing is difficult; and in the process of daily wear, the pure gold part is easily damaged and deformed. At the same time, due to the softness of pure gold, the sealing of the di...

AI Technical Summary

Problems solved by technology

Pure gold is gold with a gold content of not less than 990‰, which has good color and high value. However, due to the softness of pure gold, it is easily deformed and damaged during machining or assembly, resulting in a scrap rate in the production process. High, surface polishing is difficult; and in the process of daily wear, the pure gold part is easily damaged and deformed

At the same time, due to the softness of pure gold, the sealing of the dial of the watch is not good, and the waterproof performance of the watch is usually poor, which cannot meet the requirements for the waterproof performance of the watch when it is worn normally.

Therefore, it is difficult to achieve mass production and marketing of pure gold watches

At present, the common gold watches are all made of 18k gold, but their fineness and value are far less than pure gold watches
