Silicone Dental Wedges

Lenard Tool and Machine, Inc. (LTM) was approached by a dentistry customer to develop a molding solution for the assorted silicone dental wedges highlighted here. The mold design was derived through reverse engineering of the customer-supplied wedges. LTM worked closely with the customer as well as the molder to ensure that the intricate geometries were fully integrated into the design. A CAD prototype of a four-cavity family mold was created, and submitted to the molder for input and approval. The mold was then fabricated and submitted to the customer for additional review. Further revisions added cavity inserts that widened the variety of varying wedge models that this molding solution would produce.

Fabrication utilized a series of processes to create the mold. CNC milling was the primary construction method, along with surface grinding and bead blasting. 420 stainless pre hardened steel was selected as the mold material, offering important qualities of high hardness and excellent wearability. The synergy of these factors resulted in a mold with precise casting abilities and dimensional tolerances of only ±0.001." Fabrication concluded with a comprehensive validation of proper operation and dimensional accuracy.

A well-engineered design, coupled with quality tooling and a quick delivery time of only 3 months gave the customer a convenient, long-lasting, and cost-efficient injection molding solution. LTM displayed a stellar capability in answering a customer's needs in the conception and delivery of this project.

The strongly defined characteristics highlighted here show that LTM has class-leading skill in formulating comprehensive answers to the production questions its diverse customers bring. Contact LTM today to learn how you can take advantage of these services and more.
