Worksite Improvement Case Studies

Factory Equipment Hose Examples

Improving productivity by eliminating hose collapse and water leaks from couplings

The customer was using a tube with a cap nut pipe thread coupling for piping carrying recirculated cooling water around a dust cover injection molding machine. However, the tube would become unpressurized when the machine stopped, causing it to collapse. Water would then leak from between the tube and coupling when the tube was once again pressurized after starting the machine. Production would stop, resulting in issues interfering with work, such as production loss and the need to perform troubleshooting.

The customer decided to use HYBRID TOYORON Hose (which is built to resist collapse and retain its shape) and TOYOCONNECTOR (which prevents hose disconnections). The customer expected that using the former would allow them to increase the flow rate in order to increase the cooling ratio, while using the latter would help to standardize installation work. Since then, they have had no production issues and have been able to work without interference. They are extremely pleased with the products.
