Prototype Injection Molding for Critical Function Testing
The Challenge Our customer was developing an In Vitro Diagnostic (IVD) cartridge that required assembling a valving component to the cartridge to control fluidic flow for the assay. Standard means for assembling these types of valves into disposable IVD cartridges includes fasteners, ultrasonic welding, laser welding, heat staking and other secondary processes. The goal for this customer was to design a valve retaining feature that could assemble the valve to the cartridge by simply snapping the components together. The Collaboration Once the part was designed, the customer came to us to mold prototypes to prove out the concept. If standard
Micro Molding Requiring Material Specification And Simulation
A client approached us because they had not received acceptable parts with other prototype molding vendors. Issues included accuracy and surface finish of the 0.013” wide “teeth” features. We have extensive experience with micro-molding and molded similarly challenging features in the past, so we quoted mold fabrication and molding. There were three keys to success on this project: material selection, molding simulation and mold fabrication
