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.
