PETG Bends

Busada makes long-radius sweeps (bends) in CAB (butyrate), Provista, Polycarbonate, and PVC, but recently completed its first PETG bend. The bend was on a 24″ Radius with extended tangents. All bends are made to order, with a 10 point check to see that degree, radius, transitions, arc lengths, and end-to-end dimensions fall within tolerance. We also maintain a .125″ flatness tolerance as well as clarity passes. PETG is notorious for a quick transition temperature, and missing the proper bend point by just a few seconds will visibly pock the tubing. We maintain quartz heaters, and tight heating controls and alarms. Our technique has been evolving for over 50 years, and we consider our bend makers artisans in their trade.

If you need a bend, we can bend any bend between .5″OD to 10″OD, any angle up to 180Deg and any radius up to 110.”
