RTM speeds production of automotive composites

RTM speeds production of automotive composites

Out-of-autoclave processes, such as resin transfer moulding (RTM), as well as other fast curing epoxy systems, are accelerating the take-up of lightweight automotive composites as their rapid manufacture matches the mass production needs of this demanding industry. Klaus Ritter reports.

Corrosion-resistant heat exchangers feature pressure tubes made from DuPont PTFE

Corrosion-resistant heat exchangers feature pressure tubes made from DuPont PTFE

AlWaFlon pressure tubes supplied by Wallstein Ingenieur GmbH of Recklinghausen, Germany are made with DuPont Teflon polytetrafluoroethylene (PTFE). This enables them to resist the highly corrosive media present within the flue gas desulphurisation plants of coal-fired power stations. Unlike heat exchangers made of nickel-base alloys, these systems withstand a long-term exposure to aggressive acid mixtures.

Ceramic dielectric components enable next generation medical MRI systems

Ceramic dielectric components enable next generation medical MRI systems

Morgan Technical Ceramics is working with the University Medical Centre (UMC) Utrect in The Netherlands to design an antenna for the next generation of ultra high field medical magnetic resonance imaging (MRI) systems. Scientists have designed a radio frequency (RF) coil array element for use in MRI systems with increased magnetic strength, which will enhance the quality of images from MRI body scans.

Possibly not as well known to the consumer market as it is to its big commercial customer base, Foster Refrigerator is a byword for technologically and market leading refrigeration for the demanding foodservice, bakery and retail industries.

Perfect surfaces

Perfect surfaces

The National Facility for Ultra-Precision Surfaces in the OpTIC Glyndwr centre, St Asaph, North Wales, has emerged as one of the world's leading centres for the preparation of large surfaces of the order of one square metre to nanometre accuracy. An important aspect of this work has been the integration of both polishing and measurement within a single facility.
