[Case Study] Solved by changing material from MC nylon to urethane! Unusual noise and insufficient load in the gondola.
This is a case of material change for parts used in building maintenance gondolas. Previously, MC nylon was used, but it had issues such as abnormal noise occurring under load and failing to meet the required load performance. Therefore, the material was changed from MC nylon to urethane rubber. By utilizing the unique elasticity and excellent load performance of urethane, the abnormal noise that occurred under load was eliminated, and load performance was improved, contributing to the enhancement of the gondola's specifications.

Applications/Examples of results
Maintenance gondola The components used in the gondola require not only load performance to ensure safety but also the ability to suppress abnormal noise and vibration during operation. In this case, by switching from MC nylon to urethane rubber, we eliminated the abnormal noise that occurred under load and further improved the load performance. We achieved a specification upgrade from the conventional design. Urethane rubber can be selected based on hardness and material according to the application, allowing for material changes that consider multiple issues such as load performance, abnormal noise, vibration, and wear. We propose urethane materials tailored to the usage conditions for challenges such as "insufficient load performance with MC nylon" and "wanting to suppress abnormal noise under load."
