When Bayer came to us with a rush project for a children’s learning display we faced a daunting challenge. We needed to take clear, transparent CAB 4″ OD tubing and bend it into complex 3D shapes. This was necessary to conserve space and allow the display...
Coupling
Busada transparent sleeves can be coupled in many ways: solvent bonding, solvent spot welding, axial slit and clamping, radial slit and clamping, and heat expansion. In situations where attractiveness surpasses utility, we recommend small conical set screws. They are...
Some of our customers prefer sleeves, some prefer metal compression couplings. So, here is a shortlist of the pros and cons of both. Call the shop if you have any questions. 540-967-2882 Transparent Sleeve Compression Metal Coupling PVC CouplingFlexible...
1. Solvent-welding butyrate tubing requires, well, a solvent (acetone alone will do it), some butyrate resin, a jar, and a brush. 2. We can provide you with some “fines,” or you could cut some of the tubing scraps and generate some clean butyrate sawdust....
Today we had a request for an expanded sight glass/coupler. This is an easy blog to write because we don’t have any idea what this is being used for. Yet, it made a nice picture and it’s just one more for the record. We made this by a special process we...
Sometimes our customers need to couple dissimilar plastics tubing. Most often they couple provista (PETG) tubing with butyrate (CAB) sleeves. We recommend this technique. It is simply using the molding shrinkage of a heated tube to form a compression coupling. After...
The nomenclature of bells and flares varies throughout the industry. We follow a simple definition. 1) A flare is a sloping conical expansion of a tube. Flares assist in funneling an object or carrier into the pneumatic tube system. Flares are usually defined by ID,...
This week our challenge was to make a simple funnel flare– 3” ID tube to a 4” ID tube. The trick was to do it without tooling. The cup manufacturer company wanted only three flares to put at cup entrance points of its pneumatic transport system. Busada makes all...
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...
Nature loves logarithmic spirals and so do I. Back in my junior year of high school, I had a fabulous earth-science teacher who taught us how to do scientific research on foraminifera growing around heat “enrichment” zones from power plants in the Northern...
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...
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...
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...
The Knock Knock children’s museum in Baton Rouge is set to open this August. We are delighted to have participated in one of the principle attractions, the pneumatic tube carrier exhibit. Designed by Zaphod Beeblebrox, the helix consists of a a spiral of 60...
