As an important part of the industrial system, machinery manufacturing industry plays an important role in the global economy. With the increasingly fierce market competition and the acceleration of technological progress, how to improve production efficiency, reduce costs and ensure product quality has become the main challenge faced by enterprises. In this context, "chain" and "lean manufacturing" have become effective ways to solve these problems.

First, the role of the chain

1. Material flow: in the process of mechanical manufacturing, every link from raw material procurement to finished product delivery involves material movement. The concept of "chain" is not only limited to physical connectors, but also refers to the logistics links in the whole supply chain management. By optimizing these links, materials can reach the designated location quickly and accurately, and the inventory cost can be reduced.

2. Information transmission: In addition to physical materials, information is also an indispensable part of manufacturing. Efficient communication mechanism can ensure the smooth docking between the upper and lower processes and adjust the production plan in time to cope with market changes.

3. Quality control: Every working procedure is the key to the final quality of products. By strictly monitoring each link and establishing a feedback mechanism, quality problems can be effectively prevented and the overall level can be improved.

Second, the core concept of lean manufacturing

Lean manufacturing originated from Toyota production system, and its core lies in eliminating waste, continuous improvement and pursuing perfection. Specific performance in the following aspects:

1. Value stream analysis: identify and optimize the whole process from customer demand to product delivery, and remove non-value-added activities.

2. Pull production: arrange production and supply according to actual demand to avoid overproduction and overstocking.

3. Standardized operation: formulate unified operation specifications to reduce variation and improve work efficiency.

4. Full participation: Encourage employees to put forward suggestions for improvement and form a bottom-up innovative atmosphere.

Third, the advantages of the combination of chain and lean manufacturing

Integrating the idea of "chain" into the practice of lean manufacturing can enable enterprises to maximize the use of resources while maintaining flexibility. For example, by building a stable supplier network (that is, supply chain), we can better predict market demand and flexibly adjust production capacity; With the help of advanced information technology platform, promote information sharing among internal departments and with external partners, and accelerate the decision-making process; Implement total quality management to ensure that each node can meet the expected standards, so as to provide customers with high-quality products and services.

In a word, chain and lean manufacturing are two sharp tools to promote the development of machinery manufacturing to a higher level. Only by constantly exploring the best combination between the two can we be invincible in the global competitive environment.
