Abstract: The performance advantages of the newly full-hydraulic internal circulation two-platen injection molding machine were investigated deeply and comprehensively. The application prospects were also forecasted. Thanks to the use of internal circulation cylinders in the injection molding machine, the hydraulic system is greatly simplified. Mold-moving and mold-locking are actuated by different cylinders respectively which not only balance the force and velocity but obtain excellent mold-locking properties and high molding stability. The injection molding machine was equipped with servomotor which drives quantified pump in order to save energy and lower noise. The newly full-hydraulic internal circulation two-platen injection molding machine will be the next generation injection molding machine.

Abstract: This paper introduces the basic theory and significance to study injection molding defects. By virtue of the visualization experimental equipments, generation processes of several typical defects are directly observed and recorded. The generation mechanism of these defects is analyzed. Finally future study plan is advanced.
