In the production system of China's machinery manufacturing enterprises, there are mainly the following problems:
1. Cost management and control are difficult
The technology update speed of machinery manufacturing enterprises is faster and faster. The original product technology has not been accepted by the market for a long time. However, the renewal of technology requires cost expenditure, which is under great pressure for enterprises. The products of mechanical manufacturing are highly customized, which are basically assembled, manufactured, designed and produced according to orders. There are many specifications of products, and the production and procurement of raw materials are extremely complex, which is easy to cause additional costs; At the same time, in order to control the quality of products, it is also easy to increase costs. At present, China's mechanical processing enterprises do not have a good grasp of scientific cost accounting, so it is difficult to reduce costs, resulting in a lot of waste.
2. Production operation and production site
Due to capital constraints, the overall production concept of small and medium-sized machining enterprises in China is relatively backward, and the production and operation concept is difficult to meet the needs of market competition. Mainly reflected in: there is no perfect production control plan; The way of machine manufacturing enterprise planning without ERP; Production plan and purchase plan are not effectively combined; The complete set of parts is insufficient; Lack of accurate cost calculation; Inadequate cost control; A series of procedure documents have been formulated, but the effect of implementation varies from enterprise to manager; Management tools are relatively backward; The enterprise is still in manual decentralized management or microcomputer single management, etc.
3. Blind production leads to problems in product inventory and enterprise capital turnover
Most machinery manufacturing enterprises are high-tech enterprises, but domestic manufacturing enterprises are still seriously insufficient in core technology, which makes China's machining enterprises follow the trend of manufacturing, and there will be blind production. The products produced have been saturated in the market. If the products are produced blindly, it may lead to products that cannot be sold, which will lead to product inventory backlog, occupy a lot of funds, and lead to poor capital turnover of enterprises.
4. Problems in quality management
China's mechanical processing enterprises do not have a sound quality assurance system, and all inspection systems need to be further strengthened. The insufficient process control ability of quality will produce a lot of quality costs. The visual management, preventive management and post quality Countermeasures of quality need to be further strengthened.
