This is an example of improvement due to a change in the manufacturing method of urethane parts used in fluid control equipment. Traditionally, urethane was cast-molded to create blocks, which were then subjected to machining. However, since the air (bubbles) inside the product generated during the casting process could not be detected until machining was performed, defects were discovered after processing, resulting in losses of materials and processing man-hours. Therefore, the manufacturing method was changed from cast molding to press molding. This suppressed the generation of internal air and implemented dimensional adjustments using molds. This resulted in improved yield and reduced manufacturing costs.

This is an example of a material change for the paper feed roller used in printers. Previously, foam urethane was used, but issues with paper feeding occurred depending on the type of paper used, making stable transport a challenge. Therefore, the hardness and material of the urethane were changed to match the material and surface condition of the paper being used. By optimizing the friction characteristics with the paper, the issues with paper feeding were resolved, achieving stable transport.

• Plastic bearings

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.

This is a case study regarding the selection of wheel materials in the development of new AGVs. During the development phase, we were considering wheel materials that could withstand the load conditions required for the AGV. However, conventional general-purpose urethane rubber could not meet the necessary load requirements, making material selection a challenge. Therefore, we proposed a special urethane, 'SL-1195P,' which is specialized for load-bearing performance. By utilizing its high load-bearing capacity and excellent rolling performance, we adopted it for the AGV wheels, successfully meeting the load requirements set during the development phase.

• Plastic bearings

This is a case of changing the material of urethane rollers used in a food factory. In an environment where water is constantly applied, hydrolysis occurred with the conventional ester-based urethane. Additionally, mold developed on the surface of the rollers, posing hygiene issues. Therefore, the material of the urethane was changed from ester-based to ether-based, which has excellent hydrolysis resistance. By adding an antibacterial agent, we were able to suppress deterioration due to hydrolysis and the growth of mold, achieving stable use in harsh wet conditions.

• Plastic bearings

This is a case of material change for the fingertip components of a robot hand used in an automobile manufacturing line. In robot hands that grip metal parts such as automobile components, the edge of the parts repeatedly contacts the rubber, causing the silicone rubber used at the fingertips to wear out and requiring replacement approximately every two weeks. Therefore, the material was changed from silicone rubber to wear-resistant urethane rubber. This change significantly reduced wear caused by repeated contact with metal parts and greatly decreased the frequency of replacements. In actual usage conditions, it has been operating without issues for over a year since its introduction, contributing to reduced maintenance labor and stable operation of the production line.

• Plastic bearings

This is a case of changing the material of the tray used to set the objects being blasted in a wet blast device. Previously, synthetic rubber or metal was used, but the surface of the tray gradually wore down due to the repeated flow of a mixture of water and blast media. This particularly caused the area around the holes to be eroded, resulting in an increase in hole diameter, which led to the problem of the set objects falling. Therefore, the material of the tray was changed to highly wear-resistant urethane rubber. By suppressing wear from the blast media and preventing the expansion of the hole diameter, the longevity of the tray and stable blasting processing were achieved.

• Resin processing machine

This is a case of urethane rewrapping for wheels used on ceiling cranes in a factory. Previously, ester-based urethane was used, but due to prolonged use, hydrolysis progressed, causing the urethane to deteriorate to the point of crumbling. Therefore, the material was changed to ether-based urethane suitable for the operating environment, and rewrapping was carried out. By enhancing resistance to hydrolysis, the deterioration of urethane was suppressed, achieving a longer lifespan for the crane wheels.

The wheels of high-speed roller coasters, which operate at speeds of 140 km/h and experience gravitational forces of 4G to 6G, inevitably suffer from internal damage due to heat buildup when made from standard polyurethane, leading to delamination or a decrease in surface hardness, resulting in a sticky state. Therefore, by adopting "VULKOLLAN," we developed wheels with extremely high load-bearing capacity, wear resistance, and heat resistance that can withstand high-speed rotation and heavy loads. Please take a look at our website.
