First, the level of technology is low, the quality of precision locknuts is poor, and the manufacture of high-precision locknuts is still difficult. The core technology and key products are still dependent on imports. Large processing allowance, serious energy consumption of the lock nut and raw material consumption, long processing cycle, and low production efficiency have become bottlenecks restricting the development of the industry. The level of the industrial level of the enterprise is an important measure for the selection of the HC fasteners. one.
Second, there are fewer companies with R&D capabilities in the entire industry chain, and there is not enough willingness for R&D. Precise locknuts are the product of a large number of production technologies and production processes. If there is not a certain amount of R&D investment products that have been stuck at the low end, they will be phased out by the tide of the times.
