Experimental and numerical investigation of peel test specimen using bi-injection molding process

Abstract

Injection moulding is the most common modern process of manufacturing thermoplastic parts because of its high productivity and manufacturability to develop various geometries and complex shapes. It’s typically used to combine thermoplastics with another thermoplastic or with an elastomer to create color differences or hard and soft areas respectively.The work presented in this article focuses to optimize the processing conditions for bi-material components in well-defined geometry and functional properties. The rheo-kinetic behaviours of elastomer rubbers using Carreau-Yasuda and Isayev-Deng models with the thermal dependence assumed by an Arrhenius law were identified by the rheological tests. The bi-injection process is simulated through a finite element codes (Cadmould® 3D). The simulation results are compared to the experimental ones with good agreements with the experimental results.
