Ebalta UK has launched a manufacturing technique, Fibretemp, that is suitable for use in big moulds with a large surface area. Additionally the company has also developed two cast-to-size materials — ebablock 170 and ebablock 1820 — which can be used for applications in mould and tool-making, design, foundry markets and composites such as prepeg tools.

The Fibretemp process involves the electrical heating of a composite mould, which allows the production of composite parts, either through the use of a resin infusion system, resin-filled carbon-fibre prepreg or standard wet lay-up procedures. It does not require any post-curing or heating in an oven or autoclave.

The company said that the process results in shorter demoulding times and less energy usage.

Cast-to-size materials ebablock 170 and ebablock 1820 can be cast in bespoke dimensions and shapes, the maximum sizes of which are dependent upon the material used. They can then be machined by the customer to the final size required.

Key product features

  • During the Fibretemp process, the area to be heated is positioned close to the surface of the tool

  • Carbon laminates used in Fibretemp have a thickness of 5mm
  • Composite moulds for laminating resins include LH 26, LH 28-1 and LH 30
  • Large moulds tend to have a sandwich structure
  • Cast-to-size blocks are cast in-house
  • Ebalta’s full range includes 20 polyurethane and epoxy cast-to-size materials, such as ebablock 105, 185, 708, EP138, M007, PW920 and W, as well as accessories such as colour-matched putties and repair compounds
