Seal-less vacuum venting for injection moulding: Experimental evidence of faster, cleaner and more energy-efficient production

Key Points

To validate the effectiveness of seal-less active vacuum venting in macro-scale injection moulding processes.
Implemented experimental validation of active vacuum venting in macro-scale injection moulding.
Measured cycle time, sink mark depth, and energy consumption across different venting strategies.
Conducted statistical analysis to compare active venting with passive venting methods.
Cycle time was reduced by 23%, achieving 96.9 cycles/hour with active venting.
Sink mark depth decreased by over 65% compared to no venting, improving product quality.
Energy consumption was reduced by 15% even with the vacuum generation in use.

Abstract

• Seal-less active vacuum venting validated for macro-scale injection moulding. • Cycle time reduced by 23% with novel active venting, increasing productivity to 96.9 cycles/h. • Sink mark depth reduced by over 65% relative to no venting. • Energy consumption reduced by 15% despite vacuum generation. • Statistical analysis confirms AVV superiority over passive venting strategies.
