In PET bottle recycling machines, a bottle is brought into the machine along an infeed conveyor belt. This belt grabs the bottles and protects the user from getting too close to the crushing mechanism. For one manufacturer the welded endless extruded urethane belting they were using in their machines was not as high performing as they had expected.

To achieve the performance and long service life that they required, they needed a belt with better stability and friction to move the bottle consistently. As leaders in innovative belting solutions, at Megadyne Belt Corp, we were able to engineer a product to meet their exact requirements.

During the development process, we provided the client with a selection of higher quality materials and samples to choose from. Once material selection was complete, the re-engineered belting solution was constructed through spin casting and slitting. The finished product is composed of a dual Durometer polyurethane material with dimensions of 24″ in length, 1-½” in width, and 1/8″ thick. With better tension and an increased surface coefficient of friction the performance of the machine was significantly improved.

Megadyne Belt Corp improved on the existing design by providing this client with a belting solution that increased and improved the machine’s functionality and performance. Our expertise and knowledge enabled us to exceed the client’s expectations. To learn more about this project, please feel free to contact Megadyne Belt Corporation of America today.

  • Company using an extruded urethane belt that is welded endless to receive bottles into machine; required improved efficiencies
  • Client needed a truly endless belt that had better friction and stability
  • The Megadyne Belt Corporation of America solution was a spun cast, dual Durometer belt that had better tension and increased surface COF.
