Analysis of the rapid development of China's hardware and machinery industry
Analysis of the rapid development of China's hardware and machinery industry
With the increase of labor costs in China in the past two years, the price advantage of low- and medium-grade standard tool exports will gradually be lost, and the export volume will inevitably decrease accordingly. If tool companies continue to focus on the production of traditional standard tools, their sales volume will gradually shrink (some private small tool factories produce large quantities of traditional standard tools, and large tool factories gradually lose this part of the market due to higher costs and inability to compete) There will be no future. Therefore, China's hardware tools industry must change its concept, vigorously develop the production of high-efficiency advanced tools, replace foreign products with domestic advanced advanced tools, recapture this part of the market occupied by imported tools, and attach importance to after-sales

Competition in the die-casting mold manufacturing market is intensifying
Competition in the die-casting mold manufacturing market is intensifying
Die-casting mold manufacturers have intensified competition in the market. China's mold market competition is constantly intensifying, the mold technology content is constantly increasing, and more and more molds are high-tech products. It is understood that there are already four kinds of molds that have been listed in the "China High-tech Product Export Catalog" by relevant state departments. In fact, many molds have more technological content than these four molds, such as automotive component progressive molds, precision multi-station progressive molds, stamping molds for large and complex car parts, automatic automotive interior parts casting molds, and high strength. Plate hot-pressing molds, etc. With the development of high and new technology, more and more mold manufacturing enterprises have been
