2. Customer needs

What problems did the customer encounter:

1. The material carrying method is varied 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 work without added value. The 5S on-site is poor and the production efficiency outside the line is too low;

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. It can meet flexible production, and the processing rhythm and variety of off-line auxiliary lines are many;

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.

Lean production line benefits:

The production balance rate has been greatly improved;

The space utilization rate of the site is saved and the floor space is reduced;

Optimize the 5S site for easy management and the overall look of the company;

The first mention is flexible, can be quickly switched, and quickly respond to the market;

Reduce personnel and achieve provincialization.
