Gift rulers are used for advertising and promotion. They are divided into Steel tape (steel tape) and leather tape (PVC plastic fiber tape). They are usually cute and compact. Tape measures are also called measuring tools. Eighty-five percent of the world's tape measures are exported from China.
2, the characteristics of the tape measure
(1) The tape measure is too deformed and will not fail
Why didn't it fail? The spring in the tape measure is very long, and its range from completely relaxed to fully tightened is very large. The entire stroke of the tape measure includes it, and there is a margin at both ends, so the tape measure will not fail.
(2) Pull one meter long and pull two meters long, there is no difference in tension
The spring of the tape measure is very thin, and the amount of deformation when it is tightened is also small, so the reaction force is very small, and the force change is not felt when the rule is pulled.
China's gear mold market is mixed
Looking at the status quo of China's gear molds, it can be described as mixed. The good news is that gear mold production has a certain foundation, and the development trend of plastic gears will bring more market space to gear molds. The worry is that the level of domestic production gear molds is still some distance from the world advanced level, and Under the trend of the gear industry, especially the plastic gear industry, the domestic response to market changes is not sensitive enough, and it is difficult for supporting research to keep up with market demand. At present, medium and low gear molds can be produced in China, and high-end gear molds rely on imports. There are not many factories specializing in gear molds in China. Most of them do gear molds by the gear factory. The gear factory often has a working section or a workshop to undertake this work.
