Craftsmanship manufacturing, exploration of daily life

——2KM MUCOMAC Company's regular technical observation and exchange and strategic summary on-site meeting

I. Concept practice: craftsmanship is integrated into manufacturing genes

> Craftsmanship is at your fingertips, innovation is in the morning and evening

The company insists on integrating "lean manufacturing" and "technical exploration" into daily life, and organizes the competent departments/supervisory technical teams to go deep into the production line every week/monthly/quarterly to achieve:

✅ Quality co-governance: managers "immerse" to inspect the details of the finished product (such as micron-level precision components, surface treatment processes)

✅ Problem response in seconds: on-site discovery, on-site discussion, on-site project establishment.

✅ Experience feedback design: production line practice directly drives R&D standard upgrades

2. Normalized practice path

| **Link** | **Core actions** | **Output value** |

| **1. On-site observation** | - Supervisors lead the team to spot check key processes (such as welding/painting) - Focus on "blind corner problems" (such as yield fluctuations caused by micro-vibration of equipment) | Expose real bottlenecks and break the "report filter" |

| **2. Technical confrontation** | - Engineers demonstrate the effect of process parameter adjustment on the spot - Cross-functional debate on optimization solutions (such as material cost vs. life cycle) | Stimulate collective wisdom and make decisions more pragmatic |

| **3. Instant summary** | - Whiteboard records the root causes and countermeasures of the problem - Claim the person responsible for the research on the spot | Knowledge is accumulated without time difference, and responsibility is transferred without gaps |

| **4. Forward-looking deduction** | - Combine industry trends to predict technical gaps (such as low-carbon processes) - Sand table deduction of future production line intelligent transformation paths | Let today's improvements serve tomorrow's strategy

3. Growth point of craftsmanship culture

1. Standard evolution, talent forging field

- Convert on-site experience into the "Golden Manual of Nissan Production and Manufacturing Process"

- Establish a "defect atlas library" to warn of potential risk points

4. Future improvement direction

| **Dimension** | **Action plan** | **Milestone** |

| **Intelligent penetration** | Pilot AI visual quality inspection in feasible production lines or sections | Achieve missed detection rate ≤ 0.001% |

| **Green manufacturing** | Develop degradable processes to replace chemical electroplating

| **Craftsmanship inheritance** | Establish "Craftsmanship Studio" to cultivate more young people to love craftsmanship and become inheritance mentors

5. Supervisor’s Summary Sentences

> **“Craftsmanship is not a slogan, but a daily struggle against 0.01%” **

> **“The production line is the best innovation laboratory, and problems are the truest teachers” **

——Require all employees:

- Write the “on-site-discussion-iteration” closed loop into the job DNA.

- Demand yourself with user-level standards (for example: “blind test” N times before product delivery)

6. Long-term Action Table

| Project | Responsible Person | Key Actions | Nodes |

| Production Line Transformation Plan | Wang XX | Complete Supplier Technical Assessment | 2025.8.30 |

| Craftsmanship Micro-class Development | Li XX | Record 10 “Details Determine Life and Death” Practical Classes | Continuous Updates |

| All-staff “Finding Faults” Action | All Staff | Submit 1 Process Optimization Proposal Every Month | Permanent Mechanism |

> 2KM MUCOMAC Company has long used this framework to emphasize **normalization, immediacy, data-based, security, and standardization**, transforming "craftsmanship" from an idea into mass-producible competitiveness, and deeply integrating the craftsmanship soul into daily life and production, and casting it into the DNA of mechanical equipment, which can make users happy and feel at ease, and can also continuously improve and inherit process technology, achieve mutual benefit and forge ahead!
