What are the subtle quality defects caused by a newcomer over-tightening screws?

basic information

Proposal for Solutions | Visualizing the Difference Between "Over-tightening" and "Proper Tightening" in a Video to Share Sensations It is important to convey the degree of tightening not through "sensation" but through "visualization." To achieve this, education that demonstrates the difference between proper tightening and excessive tightening through video is effective. ● Prepare comparison videos of proper tightening and excessive tightening ● Introduce examples of deformation and cracking of components due to over-tightening ● Quantify the degree of tightening and explain the importance of torque management This will clarify "how much force should be applied when tightening," helping to prevent quality issues before they occur.

Introduction Steps | Establishing Tightening Education on the Shop Floor STEP 1 | Collect past quality defect cases and analyze the causes Identify patterns of defects caused by over-tightening screws. STEP 2 | Create comparison videos of appropriate and excessive tightening Using actual work footage, create educational materials that are visually easy to understand. STEP 3 | Incorporate videos into new employee training and have them watch before OJT Establish a flow of video viewing → practice → feedback to enhance educational effectiveness.

Introduction of Success Case | Visualization Education of Tightening Torque Significantly Reduces Quality Defects In an assembly factory for housing materials, cracks and deformations of components due to over-tightening of screws were frequent. New workers did not understand the appropriate tightening torque, resulting in dozens of quality defects occurring each month. To address this, visualization education of tightening torque was introduced. Specifically, training was conducted using comparison videos of proper tightening versus excessive tightening. As a result: ● Quality defects decreased by 70% compared to before the introduction ● New workers' understanding improved, leading to prevention of recurrence ● Training time was shortened, enabling more efficient instruction The visualization education of tightening torque led to a significant reduction in quality issues and an improvement in training efficiency.
