Research of Injection Molding Parameters with Acrylonitrile Butadiene Styrene Composition Recycled Against Mechanical Properties

Abstract

Abstract Injection molding is the most common method for mass manufacturing plastics product. The process is influenced by injection parameters, i.e.: melting temperature, injection pressure and holding pressure. The recycled material of ABS combined with pure material on 10%:90%, 20%:80% and 30%:70%. Both can affect the mechanical properties as evidenced by tensile and impact test. The ability to resist the load of tensile is obtained from the yield point, whereas the ability to resist the load of the impact is obtained from the potential energy that be able to be received. Based on the best parameters, the optimal value is generated from 10% ABS recycled, i.e. 45,87 [J] for impact strength and 34,08 [N/mm2] for tensile strength, then the optimal value is generated from 20% ABS recycled, i.e. 45,40 [J] for impact strength and 34,40 [N/mm2] for tensile strength, and then the optimal value is generated from 30% ABS recycled, i.e. 45,17 [J] for impact strength and 34,80 [N/mm2] for tensile strength.
