We received a request for a Tritan oval tube that would be used as a robotic casing. The challenge was that the tube had to fit within the wall grooves of a machined cap. Rectangular tubing, due to the extrusion process can develop stresses along its major axis....

When a pneumatic fiber transfer system required a large bell in a short space, we had to get creative. The system was in need of a bell that would transfer the fibers at high speed from a 3-5/8″ ID up to a 5 1/2 ID in about 12″ in length. That type of bell not only...
Rectangular tubing bend orientation can be confusing. Many simply call the two options the “hard way,” and the “easy way.” We designate two planes of rectangular-tube bending: Y, (around the Major axis) or X= around the minor axis. Our rectangular bends are used, by...
Butyrate, being a cellulosic, is friendly to most fabrications. The days are past when one could purchase butyrate fittings such as elbows and tees, nevertheless, butyrate pipe can be connected to metal or PVC pipe by means of compression fittings, slip fit and O-ring...
In any pneumatic tubing system, the installer must choose not only the pathway of the tubing, the radius of the bends, and airspeed, but also support. One can support the tubing by many means but sometimes the engineer needs to accommodate for a long span. In cases...
Is butyrate an antistat? We get this question often, and the answer is 'at times' and 'no.' Every winter we receive calls asking for help with static buildup in pneumatic systems. Lower humidity brings an increase in static electricity. In pneumatic systems, you can...
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. 3. I like to...
Rectangular transparent tubing formed in an extrusion vacuum system has some inherent problems in clarity. For one, the vacuum sizer heads need extra length to combat the vacuum's tendency to round the tube. This tends to introduce draglines and chatter marks. We have...
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...
Here above we have an example of a larger OD tight-radius-bends. This one is a 4.750 OD tube bent on a 13" center-line radius. You will notice that the right side of the bend has an extended tangent and the accuracy of the bend is measured by the inside wall...
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...
2) Transparency So how do scientists measure clear plastic? The boundaries between ‘transparent’ or ‘clear’ and ‘translucent’ or ‘opaque’ are often highly subjective. What is acceptable for one observer is not necessarily acceptable for another. One test for measuring...
Quite often our customers ask us for bends without tangents. Mostly it is for aesthetic reasons, but often enough it is for a particular process need. Such bends bring a special challenge. Thermoplastics' bends, due to the requirement of secondary heating, have...
A Spanish museum contacted us to see if we could fix a work of art. The actual artwork is an elaborate set of collars that connect small-diameter tubing bent on a tight-radius circle. They sent us a sample of an acrylic tube. Acrylic is famous for cracking, crazing,...
