Over molding of plastics with elastomers is common, but due to limitations of TPE materials, their use in microfluidic applications have been limited. Recent developments in TPE materials have given certain TPE materials properties similar to silicone. Silicone has attractive properties for microfluidic applications, but as an over molding material, its drawbacks have limited its use. Design solutions for over molded valves, pumps and reservoirs using TPE materials that solve problems associated with elastomeric valves and pumps made with other methods and elastomeric materials are described. Solutions are presented to issues including leaking, sealing and assembly. A basic design for a normally closed valve and expandable reservoir that is made possible by overmolding with the new elastomers and would not be possible to manufacture with any other method is illustrated in detail. Previously, normally closed valves have been difficult to develop and/or costly to implement, but by using this over molded design they add only nominal, if any, cost to the part. Exchanging fluids between fixed volume reservoirs without creating a void or adding pressure and /or bubbles to the system has always been a problem. Expandable reservoirs eliminate these challenges because they do not add any dead air in the system, reducing the risk of bubbles, additionally they can be used to dissipate, equalize and capture pressure generated by a user or a pump.
