Micro overmolding is becoming more important with the rapid development and applications of microproducts in bioengineering, electronics and other areas in recent years. This paper presents our findings in studying polymer interfaces in micro channels of a micro mold during overmolding process. The bonding strengths between polycarbonate (PC) and thermoplastic polyurethanes (TPU) were examined and compared under different overmolding conditions. Results show bonding behaviors in micro channels are not only affected by temperatures, they are also influenced by surface roughness.
