Custom Mold Tooling Design & Manufacturing Services












At Lenard Tool & Machine, Inc. we provide advanced tool design and manufacturing for the elastomer molding industry. Our experienced team can provide 2D and 3D CAD modeling, prototypes, testing, and technical support. We can design and manufacture compression molds, hot or cold runner injection molds, hot or cold transfer molds, LIM book molds, to run in vertical and horizontal molding presses. Our team can also add additional tooling options such as extrusion pin and die sets, demolding devices, and clicker die sets, just to name a few. A large range of materials are available for our tools that include pre-hard stainless steel cavity plates, 4140 pre-hard cavity plates, 1144 plates and cores, and H13, S7, 420 SS and 440 SS heat treated cavity inserts and cores. We can send out cavity plates, inserts and cores to be plated as well. Some examples of the materials that are run in our tools include Silicone, EPDM, Neoprene, Viton and natural rubber.
We offer many processes for tool manufacturing which include, blanchard and surface grinding, CNC milling, CNC turning, sinker and wire EMD, bead blasting and welding. Our product dimensions are all part and press specific and can range in length and width from 4" to 42" and 1/16" to 16" in height. At Lenard Tool and Machine we guarantee our product with quality checks during the design phase and tool fabrication to verify customer specifications, in addition to dimensional and functionality inspections. Our tolerances are part specific and can range between ±.0005" to ±.001". Our lead times are quoted on a job by job basis and emergency and rush services are available.
For more information on our tool design and fabrication capability, see the table below, or contact us directly.
