Advances in engineering rely on the development of new materials. The materials must have improved properties, capable of being tailored to a specific application need, to fulfil the requirements of ...

Extrusion is a process used for creating a product (an extrudate) by forcing a material through a die or an orifice to form a shape, or alternatively an extruder is used to produce semi-finished or ...

BWE’s new SheathEx process is an extension of its Conform and Conklad continuous extrusion technology. The SheathEx machine extrudes a continuous and seamless aluminium tube (max. diameter 165mm) from ...

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 ...

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 ...

The authors compare three systems of single-screw extrusion using binary formulations for their suitability for producing pellets of various formulations and under various spheronization conditions.

IT has been known for the past two decades that in the extrusion of lead cable sheaths and pipe on the hydraulic press, the presence of oxides may result in the existence of irregularities in the ...

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 ...

LEAD is a very suitable metal for providing a watertight covering to an electric cable buried in the earth. The weight of the lead sheaths made per annum in Britain alone is 64,000 tons. Taking into ...
