A medical/safety industry customer approached Lenard Tool & Machine, Inc. (LTM) to create a production mold for the manufacture of the silicone mouthpiece highlighted here. LTM utilized its fully developed suite of design and fabrication talent to construct a molding solution capable of accurately casting the mouthpiece.

LTM worked closely with the customer while producing initial mold prototypes in a CAD/CAM environment. A horizontally-oriented injection press mold was formed, featuring heated cavity plates and an ejection system capable of moving the plates and mold cores. 420 pre hard stainless steel was specified for the material, giving exceptional surface hardness and wearability properties to the mold. Input and approval from the molder was implemented during the design phase.

LTM fabricated the production mold design through a series of material removal procedures. CNC-type milling and turning were the primary processes, followed by refinement through surface grinding and bead blasting. LTM's excellent skill in mold tooling allowed for required casting wall thickness of 0.050" and tight tolerances of ±0.001." Subsequent validation of dimensional accuracy as well as functionality ensured that the final product would render high-performance operation.

Completing the project in a speedy 8 weeks, LTM resolutely satisfied the customer's need for a molding solution. The end product was cost-efficient with the ability to recreate the complex shape of the silicone mouthpiece with high precision.This project is one of many that exemplify LTM's excellent talent in the design and fabrication field, delivering high quality production molding solutions to all customers.
