Guide To Suppliers

It is no secret that electric and hybrid vehicles are taking pole position in the future of the automotive market.

A leading global pharmaceutical company is using a low friction, impact-resistant grade of Delrin acetal homopolymer resin for two components in a new insulin pen.

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.

Using IMHP (In-Mould Hold Pressure) technology from DuPont, hold pressure is applied using a separate mechanism integrated within the mould during the screw-dosing phase. This parallel arrangement of two injection moulding phases can help reduce cycle time. The actual time saving is largely determined by the degree of crystallinity of the processed material and the shot volume.

Pressures to save weight and costs in the automotive sector are leading to innovative plastic replacements for more traditional metal components. In this recent application a moulded glass reinforced nylon was chosen in preference to die cast magnesium for the housing of an electronic air suspension system controller
