Abstract
The objective of this study was to manufacture thermoplastic elastomer tubes by a novel water assisted injection moulding technology and to experimentally investigate the effects of various processing parameters on the moulded parts quality. Styrene-ethylene/butylene-styrene (SEBS) compounds based thermoplastic elastomers were used for all the experiments. Experiments were carried out on a lab-developed water assisted injection-moulding system, which included a water pump, a water injection pin, a water tank equipped with a temperature regulator, a pressure accumulator, and a control circuit A porous type water injection pin was designed and made to mold the parts. After moulding, the lengths of water penetration as well as the hollowed core ratios in molded tubes were measured. The effects of different processing parameters on the hollowed core ratios were determined.
