Butyrate tubing (CAB) is known for its toughness, but when properly extruded it can compete even with cast acrylic in clarity. At Busada, we cater to the small order; we run in small lots and low screw speeds. Quality matters here, not throughput. We recently sent a...
Tubing Applications
We often fit bends to pneumatic (or other) systems from a distance. We ask the customers to send us as much information as they can provide. From that, we do our best to calculate OD, radius, and angle of the bend. Here is another example from last week. As you can...
A water treatment company needed a system to display its product in its showroom and for trade shows. The system required 4″ Schedule 40 Pipe that would be bent, coupled, threaded, and coupled with tees and wyes. It was challenging in a number of ways. We had to...
When a request for a custom air filter came in with an associated drawing we got to work. The original print imposed an untenable bend upon the 2″ OD butyrate tube, so we suggested mitering. After a bit of back and forth, we suggested another change. As this...
Over two years ago we received an inquiry from Glenn Stracher, a geologist at EGSC. He needed a plastics tube that could be fabricated and colored to function as a replacement piece for an instrument panel on a classic Chevelle restoration. Glenn gave us constant...
We received a beautiful panoramic virtual tour of the Roasting Plant’s restaurant in Michigan. The engineering here is a work of art. We provide tubing and bends in a Provista PETG formula that is NSF-compliant and FDA-approved. Click this link for a beautiful...
We were approached by a lighting manufacturer to form a suitable transparent casing and shell for an industrial light. Normally extruding this would be the answer, but the quantity needed did not justify the tooling. So, using a secondary fabrication process, we...
A well-known entertainment company contacted us about a special project. They wanted a large OD tube to move along the sides and corners of an amusement building. But, their print called for an 8″ OD tube on a 24″ radius. This required a...
We can bend to almost any design. Here, we received a challenge from a breakfast nook company for a three-dimensional bend on a 3.259 OD Tritan tube. Pictured here is the model, we cannot show the final piece. The drawing shows the challenge. Here is the result....
In July we received a print to bend tubing for a trade-show coffee roaster display. We had two weeks to meet a deadline. We elected to make the bends out of a 3″ OD butyrate tubing with a .125 wall. The bend radii were as tight as 8″ CLR. Dry ice worked as...
When the call came in to produce a large run of 6″ x 3.5″ Rectangular Butyrate Tubing in a short time, we got to work. From inquiry to drawing, design, tooling, and then to production it took 3 weeks. We were pleased with the results. Above, we see an...
We recently had quite a challenge from Metraflex regarding a transparent tight-radius 4” pipe 90° bend. They required a transparent 4” Sch 40 long-radius elbow to observe a metal fin in a fluid system. The pipe bend needed to maintain a tight tolerance for ovality as...
Recently we received a request for some “giant elbows, about a 15 ft. radius to load material up a silo. This was hard for me to comprehend— for these bends would be not only huge but bent three-dimensionally. When the prints and drawings came in this seemed...
Recently we had a request to make circular and helical small diameter bends for a lighting project. We designed special heaters for the project and made our prototypes with clear, transparent CAB (butyrate). The trick is proper annealing. We not only heat our bends to...
