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

\u003cdiv id=\"abss0001\"\u0026gt\u003cp id=\"spara0123\"\u0026gtInjection moulding is the most \ncommon modern process of manufacturing thermoplastic parts because of \nits high productivity and manufacturability to develop various \ngeometries and complex shapes. It’s typically used to combine \nthermoplastics with another thermoplastic or with an elastomer to create\n color differences or hard and soft areas respectively. The\n work presented in this article focuses to optimize the processing \nconditions for bi-material components in well-defined geometry and \nfunctional properties. The rheo-kinetic behaviours of elastomer rubbers \nusing Carreau-Yasuda and Isayev-Deng models with the thermal dependence \nassumed by an Arrhenius law were identified by the rheological tests. \nThe bi-injection process is simulated through a finite element codes \n(Cadmould® 3D). The simulation results are compared to the experimental \nones with good agreements with the experimental results.\u003c/p\u0026gt\u003c/div\u0026gt
