2. Customer needs

What problems did the customer encounter:

1. The material carrying method is varied; the tooling return line is too long and the flexibility is poor; the production line is more traditional; the space utilization rate is not high;

2. The flow of people, logistics, and detours lead to a large number of incidental operations without added value. The 5S on-site is poor, and there are too many WIP products on site;

3. Information transmission depends on information, information records are written, and information is lagging;

4. The material distribution method is a typical one-time large-volume delivery method. Once an abnormality occurs in a material, it will cause batch errors.

5. There are a large number of incidental work with no added value during the operation.

Lean production line analysis:

1. Designing the layout and quantity of lean production lines according to TT;

2. The line body meets the requirements of flexibility and expandability, and can be continuously upgraded to meet the production needs of different products and different processes;

3. The lean production line equipment is modularized, and the lean production line can be assembled freely to improve the efficiency and longevity of the equipment;

4. According to PQPQ (order quantity, process path), classify the line body.
