Compared with other media, gas model entered China late, but it developed quite rapidly. No matter from coastal open cities, or from megacities to ordinary cities, from ordinary cities to relatively prosperous township markets, we can see them everywhere. What is extremely disproportionate to this is that most cities in China have no professional manufacturers specializing in manufacturing and producing gas molds. According to the social demand for the development of gas mold industry and the actual development of our factory over the years, I think there should be at least 3-5 gas mold companies in each county, city and district (county-level unit). Only in this way can we meet the growing demand of the gas mold market. Therefore, the gas mold industry in China is like a new sun with a very broad market prospect, and it is a "sunrise industry" and a "green industry" in 2 1 century.
