Increasingly smaller medical devices require tighter tolerances that make extrusion process control more difficult. Photos courtesy of TEEL PLASTICS INC. As medical devices get smaller and tolerances ...

Continuous extrusion encompasses a class of metal forming techniques in which billet or feedstock is continuously forced through a die to produce long-sections of uniform cross-section. Unlike batch ...

Using a proprietary process, Microspec extrudes single- and multilumen bump tubing for minimally invasive applications. The proliferation of minimally invasive procedures has prompted engineers and ...

Editor?s note: The author, Donald E. De Laney, a consultant in polymer process rheology, worked with GE for 17 years and has worked with Dynisco over the past eight years. The plastics compounding and ...

A presentation at the Leistritz Pharmaceutical-Nutraceutical Extrusion Seminar explained how simulation tools benefit the development process. Twin-screw extruders (TSE) are used in multiple ...

The authors examine the influence of glass-transition temperature, melt viscosity, degradation temperature, and process settings. Hot-melt extrusion (HME) technology is prominent in the pharmaceutical ...

The hot melt extrusion (HME) process can be employed in the production of a wide range of pharmaceutical dosage forms, including capsules, tablets, lozenges and implants. HME is suitable for both ...

For decades, manufacturing plastic-bonded high explosives, or PBXs, has relied on legacy processes like slurry coating. In ...

We have a fascination with gloss. Think of shining shoes, polishing apples for the teacher, don’t touch my car, squeaky-clean and more. Somehow, shiny noses are the other way around, which is why we ...
