Injection transfer moulding (ITM) is a combination of the well known injection moulding and transfer moulding processes. By ITM the melt is not injected into the cavities directly, but first is led into a so called transfer chamber. In a second process step the melt is transferred into the mould cavities by a piston / cylinder system. Although the ITM process provides many advantages compared to conventional injection moulding, ITM has until now only been used for processing crosslinkable plastics. Research work at the Institute of Plastics Processing (IKV) made the ITM process accessible for the processing of thermoplastic materials by use of a newly developed mould. A main advantage of the new technology is the low injection pressure necessary to fill all cavities uniformly due to the short flow paths. Plastics processed by ITM are exposed to lower shear stresses. Herewith the ITM process allows the production of parts with lower inner stresses and reduced shrinkage and warpage. This paper discusses the mould technology, the course of the ITM process as well as the resulting part qualities. In addition, a first comparison of the ITM process to conventional moulds with hot runner systems is given.
