    Copper increases efficiency in injection moulding

    Replacing traditional steel moulds with those made from copper alloys could make injection moulding of plastic packaging more productive, according to research led by UK-based Copperplas International Ltd. Project Aimtech aims to reduce cycle time and improve finish quality to increase competiveness with the rapidly developing Chinese supply chain. Copper alloy moulds are five to six times more thermally conductive than steel for injecting molten plastic at high pressure.

  • Modelling negative thermal expansion

    Scientists have devised a model to minimise thermal expansion on a structures such as bridges and fuel cells. By having at least one component that has a different thermal expansion coefficient from the rest, researchers can display thermal expansion.
  • Corrosion Management in the Power Industry: Current Problems and Future Challenges - meeting report

    This was a very successful meeting, held in London in April 2007, attracting a total of 33 delegates from a wide range of UK manufacturers and utilities. The workshop included...

    Materials Resource Centre opens

    MADE, the materials and design node of the Materials KTN, has opened a Materials Resource Centre in central London.
  • Graphene exists in the free state

    Scientists have attempted to prove that a 2D gauze of carbon atoms, called graphene, can exist in the free state. The material has potential for use in the manufacturing of micromechanical switches and electronic transistors, and more immediately as a substrate to aid transmission electron microscopy.
  • Europe’s first state-of-the-art waterjet machining centre

    Europe's first state-of-the-art centre will explore waterjet machining as a viable alternative to using laser processing for 3D parts for the aerospace industry. Waterjet technology has erosive properties for cutting materials such as glass, polymers and metals, and uses grit and water rather than toxic chemicals.
  • The first ever liquid transistor

    The first ever liquid transistor has been created, according to a team of researchers at the University of Cincinnati, USA. The new device can directly convert charge-related information from the liquid state into conventional electronic signals, for advances in biotechnology and flat panel displays.
  • Non-reflective coating for optical devices

    A material that has almost the same refractive index of air has been created, by positioning low-reflective silica nanorods onto a thin film of aluminium nitrate. The result is an innovative coating that reflects virtually no light allowing researchers to potentially reduce the negative effect on the performance of optical components and devices.
  • Energy efficient bearings from SKF

    Bearings from SKF, based in Sweden, use 30% less energy as a result of design innovations relating to surface topography, raceway profiles, optimised internal geometry, a special polymer cage, lower friction grease and, for tapered roller bearings, an optimised set of rollers. This will be exploited in heavy industry, wind energy and conveyors and extruders for materials processing.
