The year was 1975. While a student at Bucknell I had a little business on the side. It was called "Last Rush" and the slogan was "Use the right tool for the job." I made hundreds of "tubular items" and sold them to head shops and to people via mail order. I would...
Butyrate (CAB)
Do you need an off-the-charts bend of transparent tubing? How about a 14° 200" R (no tangents)? We received an interesting call this week. A school is preparing a model of a space station to be displayed at NASA. Our little part in this was to scale down a 12 ft...
Decades ago, Rodney Hunt Company, Orange MA and Waterman Industries, Inc., Exeter, CA began using our butyrate tubing to protect their stems from weathering. Butyrate (CAB) protectors provided clarity, UV protection, and fracture resistance without the weight and...
We are privileged to participate in a helical bend for a children's museum in Baton Rouge. More later as this develops. The helix (hexagonal) has a 96" radius and composed of (CAB) cellulose acetate tubing (4.125"ID). Model 1 and support circle.Ideas on...
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,...
For decades, Busada has been extruding sample core tubing for oceanographic research; and off-shore bottom sampling in the search for submerged oil reserves. The clear tubing may be removed intact from the pipe, preserving the original spatial relations of the sample...
VM Fiber Feeder is a global leader in fiber dispensing technology for asphalt, concrete, custom applications and an international fiber distributor. Recently they asked us to supply them an offset bend. Here is their pneumatic VM Fiber Feeder in action using our...
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....
Often in pneumatic conveyance, one needs to bring two lines together. In such cases, transparency offers obvious advantages; a transparent connector immediately shows a visual of the area most likely to jam. At Busada we have made various Wyes and other connectors for...
