Project: Machine Improvement to Enhance PPM Speed and Reduce Breakdowns. Improve machine performance to increase Parts Per Minute (PPM) speed and minimize machine downtime caused by breakdowns and alarms. The root cause is the use of tools with unsuitable dimensions that are difficult to control, leading to frequent stoppages for correction which Analyzing the dimensional inaccuracies of existing tools causes alarms and breakdowns, and improving the machine for achieving universal compatibility of machine components across all production models enhances flexibility

The result. After the machine improvement, enabling compatibility with all dimensions, the occurrence of alarms decreased from approximately 20 times per shift to only 3 times, based on data collected over a 3-month period.

Project: In addition, the PPM improvement project continued by collecting data on other machine-related issues and analyzing the root causes using the 5 Whys methodology. Subsequently, cross-functional collaboration was initiated with several related departments to implement corrective actions.

• Managed control and improved all production processes in order to achieve the target / KPI as planned
• Optimized company resource usage to be more proper and efficient (4M: Man, Machine, Material, Method).
• Exhibit data about Line balancing in the process.
• Generate Monthly production planning.
• Coordinated and led Kaizen and innovation activities to enhance production.
• Study how employees work, using knowledge in motion and time study.
• Preparation document about the production, such as Work instruction, Q-point, Non-Conformance Report, Corrective Action Report, etc.

Project: Line balance by 7 waste and ECRS tool to reduce the setup time for jig and fixture on machines for each model, minimize cycle time in production, streamline production process steps, reduce manpower requirements, and eliminate the use of unnecessary machinery by optimizing certain production steps to be performed on a single machine.

The results show that after implementing Motion changes in production and incorporating Karakuri and optimizing the Balance Process, the setup time for machines was reduced by 3 hours per production model. Additionally, the number of workers required per machine was reduced from 3 to 2 for 5 machines, and the number of unnecessary machines was decreased by 2

Project: Treatment of Machine Coolant to Extend Its Service Life. Develop a coolant treatment system to extend the usable life of machine coolant, currently requiring replacement every 3 months at a high cost. The frequent replacement is due to contamination from oil in the workpiece, causing coolant degradation, which negatively impacts workpiece dimensions and the health of machine operators.

The results show implemented coolant treatment system yielded the following outcomes:

• Extended the lifespan of coolant tanks from 3 months to 8 months per tank.
• Reduced coolant replacement costs by approximately 200,000 THB.
• Decreased the risk of employees developing allergic reactions or skin rashes caused by contaminated coolant.
• Enabled the sale of recovered contaminated oil at 2,000 THB per tank per month.

• Control and improve the Automated Storage and Retrieval System (ASRS).
• Service support when there is a problem with the machine or related issues that need to be analyzed and resolved for various branches in Thailand.
• Develop applications to deliver products that meet standards and are convenient to customers and employees.
• Documented technical processes and supported team operations.
