Silicone Punch & Die Unit

Lenard Tool & Machine, Inc. (LTM) was approached by a Medical industry customer to formulate a complete production system for the silicone part highlighted here. LTM would have to develop a production methodology that was capable of producing the silicone product with maximum efficiency and performance.

LTM utilized CAD/CAM software and the consultancy of a molder as the foundational work of the design phase. An A2 full hard punch, mated with an A6 full hard die, was selected to cut the silicone part from .030" sheet stock material. Although a simple design, LTM's experience and talent dictated that such a production method would be cost efficient and allow for high yield rates.

LTM fabricated the silicone part punch and die unit utilizing CNC milling, center-less grinding, along with surface grinding to provide excellent dimensional precision. A comprehensive evaluation of the geometry and operation of the unit helped guarantee an extended and long-lasting production system.

In only 8 weeks from conception to completion, LTM facilitated the needs of this customer with a well-engineered solution. The punch and die unit provided an efficient and cost-effective production system that would remain useful for years to come. Contact LTM today to learn how you can tap into this class-leading reserve of engineering talent.
