We frequently are asked to make UBends (180°) bends. In a UBend, the offset is twice the radius, and keeping the offset is the trick. In thermoplastics bends the tubing tends to pull in or out (memory) and work as a thermometer with radiant heat. Our process minimizes movement of the bend offset. For example, we were asked for an offset
Our process minimizes movement of the bend offset. For example, we were asked for an offset of 55.625" with a 4.75"OD bend.
Here is a UBbend at use in a test machine for puck conveyance.
By the way, compare the transparency of Busada 200 tubing bends to clear PVC Bends.
As pictured to the right, clear PVC is blue and cloudy as compared to our transparent butyrate (or Provista PETG) bends.
