Recently we were given the challenge to produce a tight radius bend to replace a metal fruit chute (peaches). The bend needed a 6" ID and a tight 12" radius. We were able to accomplish this by flaring a 5" ID tube to 6.5" ID and bending the tube 3D to come under the...
Provista (PETG)
For top-of-the-line clarity in bends, nothing comes close to our Provista (PETG) line with monitored air packing. For clarity one has to control the packing material. This method was developed for a line of retail-coffee-house bends. Nothing is clearer, and this...
I have enjoyed my time corresponding with Carey Parks. We talk colors, engraving, music, and the lot. Butyrate and Provista (PETG) have specific acoustic properties and it is something that I would like to study further. For example, Onda Corp. has some data on...
We have been making bends for The Roasting Plant as they build new and upgrade existing restaurants. They and their engineers from Advanced Design (FL) have tight tolerances and every bend is different. We extrude Provista tubing (PETG) and coat it with our ACS...
Provista (PETG) tubing, when properly extruded and polished is superior to cast acrylic in every way. When flame polished, it is spectacular for clarity. The picture above shows how a Provista tube shines when flame polished. This 6" OD tube, FDA approved and NSF...
Problem: We had a challenge to produce a 4"CLR bend in our 1-1/2" pipe in clear, transparent, Provista (PETG). Provista is very clear, has NSF approval for food contact, no odor, and very good chemical resistance. But, it has a very short transition temperature in...
We recently filled an order with specialty bends for Provista (PETG) UVO. This clear, transparent conveyance system is UV stabilized and FDA/NSF approved. We also supplied sleeves for the order. In order to maintain NSF standards, the sleeve is thick-walled. This...
We are delighted to be supplying The Roasting Place with its new line of Provista (PETG) tubing. Their design team has been searching for a more aesthetic and functional tube for their coffee-bean pneumatic transport. Provista UVO not only has FDA, but NSF compliance,...
Often our customers need a specialized rectangular tube, but not enough to justify the expense of tooling and an extrusion run. Our answer is to fabricate from round. Recently, a customer needed a simple 4" x 5" rectangular tube and bend. By secondary fabrication...
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,...
Problem: Extrude a heavy-walled small diameter pneumatic tube; in this case the wall area composes 75% of the tubing area. The difficulty comes in maintaining wall uniformity while eliminating “lensing,” uneven cooling, uneven shrinkage (curling) and chatter lines....
