Sheet mettle

Article Abstract:

The use of plastic sheeting is becoming increasingly popular in applications previously associated with toughened plate glass. Obvious examples include walkways, bus shelters and street advertising hoardings. The toughness and lightness of acrylic or polycarbonate sheet materials makes them useful for several safety applications. GE Plastics has developed the latest polycarbonate sheet, Lexan XL10, a thermoformable range that is virtually unbreakable. The plastics industry is aiming to replace glass in other areas, including automobile windshields.

Moulding shows its mettle

Article Abstract:

Metal injection molding may finally be approaching acceptability and wider use. The technique uses fine metallic powders, less than 10 micrometers, mixed with a wax/polymer binder and injected under pressure into a mold before it is cooked and sintered. The process yields good surface finish, near-net shape and high production rates, but problems with consistency and continuing pressure from competing processes have limited its market penetration.

Smart fluids

Article Abstract:

Electrorheological fluids (ERF) which are suspensions of electrically conducting or semiconducting materials in non-conducting liquids are being applied in the automobile industry. Carl Schenck AG of Darmstadt, Germany, has come up with a new type of pumps using ERF developed by Bayer AG. These pumps which do not require the usual mechanical valves, will be utilized as components of the power steering of motor vehicles.
