ELASTOMER COMPOSITES. Composites between thermoplastics and elastomers are still a special field of multi-component injection moulding. The system supplier Rico can draw on its 10 years' experience in the construction of such moulds and complete systems. At K2004, a complete production cell producing PA and LSR sealing membranes is displayed. The mould technology joins "hot" PA to "cold" LSR elements for high-quality mass production.
