PEEK Funnel Tip

This Event Occurred in April of 2012

Molding a pipette-shaped part with a .015” wall x .372” long followed by a .008” wall x .100” is challenging enough by most mold and molding standards. Add to that molding these micro parts from VICTREX® PEEK 90G (polyetheretherketone) material, selected for its high strength properties needed by the customer, and the challenge is even greater. Now, how about doing this in a 4-cavity mold? An 8-cavity mold? Can a Cpk of 1.33 be achieved on this wall section? These are the challenges and questions Mold Craft set out to address when a customer came to them with this medical “funnel tip” component. However, this project could not have been accomplished successfully without Mold Craft’s partners in mold fill/material flow simulation, Meltflipper® technology and a molding press designed for micro molding.

Designing & Building Precision Injection Molds

Mold Craft created this small, thin-walled part with different surface finishes, special cavity inserts, and very tight tolerances. This part demonstrates Mold Craft’s Design for Manufacturing (DFM) capabilities, small pitch features within the cavity and ability to maintain tolerances as tight as ±.0001” resulting in crisp detail and interchangeable cavity inserts.
