Product & Tooling Development of a Silicone Incontinence Device for the Medical Industry
Lenard Tool & Machine, Inc. (LTM) was contacted by a medical industry customer to provide a production molding solution for the silicone incontinence device highlighted here. LTM's pre-design work revealed that a unique reverse engineering approach would be necessary to create a high-performance mold system for the complex silicone device.
Design work started in earnest with analysis of customer-provided models, drawings, and molds. The silicone device would require steel insert pieces as well as supporting wirework, all coated in silicon casting. With consultation from the molder, LTM developed a horizontally oriented injection mold that utilized heated cavity plates and shuttling cores. Pre-hardened 420 stainless steel was selected for the cavity plates, with the cores constructed out of plated 1144 steel.
For fabrication of the production mold LTM utilized CNC-type milling and turning, electrical discharge machining (EDM) and gun drilling. These processes were followed by refinement through surface grinding and bead blasting, operating under tolerances of ±0.005." A comprehensive evaluation of geometrical accuracy and function concluded the fabrication phase.
Delivering in a speedy 6 months, LTM brought to the customer an efficient and cost-effective solution for production of the silicone incontinence device. The end-result was a high-performance injection molding system that had been born from the experience driven engineering foundation necessary for such a reverse engineering project.
Experiences such as this one are not exceptions at LTM; they are the rule. Tremendously high quality, long lasting, and financially smart production molding solutions are available to all. Contact LTM today to learn even more.
