In recent years, is known as the mother of China's mold industry has grown, more and more manufacturers saw great potential for development of cement covers mold industry, have added to the production of cement covers mold the tide in the past, but the development of the industry The situation was a bit slow somewhat awkward touches people, then the cause embarrassment generated by what you do? The first step in the production of cement covers mold design reasonable mold designers improve quality the most important step, so we might want to choose the best strength of the structure of the program, designed to reasonably steel mold manufacturer, full consideration of technical parts Claim. The problem we face to come, most of the companies to develop relatively weak. On the one hand is the low proportion of professional designers and technicians uneven level is not high enough, on the other hand the proportion of business investment in research and development of small U-shaped channel steel mold manufacturers, they only consider the immediate interests, without considering the enterprise long-term development.
