Intrusion moulding

Xanthos and co-workers [12] did some research in which LDPE was melt blended with either automotive shredder residue, carpet hacking residue or mixtures of the two and prototype blocks were intrusion moulded from them. These blocks were evaluated for use as a wood substitute for the building industry by conducting tests to determine their short-term and long-term mechanical properties, flammability, thermal conductivity and heavy metal and total organic carbon leaching behaviour. The performance of these prototypes was compared with that of wood and the composites containing carpet residue were found to be favourable as replacements for wood thermal barrier components in a steel-based stud assembly.

The Remaker, built by Kleindiant in Germany, employs an intrusion moulder. The screw-plasticised mixture is injected at a relatively low pressure through a large diameter gate into aluminium moulds mounted on a conventional press. This machine is very effective for small flexible items but cannot handle mixtures containing PVC because of the relatively long dwell time in the machine. 

Working on the basis that necessity is the mother of invention a new anti-intrusion shell product from RocTool would appear to satisfy a number of needs. The shell, using reformulated conductive polyester composite material, incorporates a smart card within the moulding which, in the event of threatened integrity, can transmit information. Typical product applications include the transport of hazardous or sensitive materials, protection of electronic equipment, security of buildings, the ensuring of system integrity in IT systems and for double protection in an alarm system.
