The engraving or etching of company names, trademarks, patterns and words on the bell case, the bottom cover, the buckle, the band and the ring is indispensable for the bell. In order to meet the different needs of the market and customers, the manufacturer has introduced different types of engraving methods for customers to choose, such as stencilling engraving, etching and laser engraving.
According to the manufacturer interviewed, each carving method involves different steps and has its own features. The use of oil steel or chrome steel stencils to carve patterns of steel engraving is very traditional engraving methods. According to one of the manufacturers interviewed, the word height on the steel seal is generally 0.9 mm, but the most delicate is only 0.5 mm. In addition, through the treatment of the electric furnace, steel printing can be enhanced to create clear and textured effect of the concavo-convex words and patterns, so gradually popular.
Etching is another method of engraving that can produce a more detailed and smooth effect. However, this approach is somewhat less environmentally friendly because it involves chemical liquids. However, the manufacturer is careful to ensure that each etching process, i.e. from drawings or real plates, screen film, etching to oil is properly done. The etching lines on the bottom cover are only a few microns deep, while the etching of the ring is deeper.
Based on the different styles of clocks and watches, the carving design of clock parts also needs to be constantly modified, so customers require fast delivery time and flexible production process. The birth of laser engraving helps manufacturers and customers solve these problems. Among the manufacturers interviewed, two were engaged in laser engraving business, one was to provide laser engraving services, the other was to produce laser engraving machines. Two manufacturers also agree that laser engraving can help produce high quality and stable products.
First, laser engraving can be applied to any material, be it stainless steel, copper, aluminum, alloy, ceramic, silver or plastic. Second, laser engraving is fast and reliable. For example, a straight line can be carved at a speed of 1,500 millimeters per second, and when the pattern is confirmed, the engraving machine can operate 24 hours a day, ensuring fast delivery. In addition, laser engraving is computerized, and you can control every engraving to be absolutely the same, smooth and detailed. The most subtle laser engraving font is only about 1.064 microns. Also, laser engraving is environmentally friendly and economical without chemical materials and contaminants.
