Component designers no longer need be constrained by the limitations of injection molding tool design. The exact fitting, in the optimal layout for the process or product concept, is available with a line of Build-a-Part bondable components, designed for use with gases or liquids. The Build-a-Part system is based on combining interchangeable components, joining junction blocks and luer, hose barb, or threaded features to create the desired configuration. The features are bonded to the junction blocks using commonly available adhesives such as cyanoacrylates or solvents such as acetone. Junction blocks and features may be bonded together to create multi-port, multi-axis products that receive and redirect fluid flow in whatever direction the designer desires.
