As an internationally recognized manufacturer of die set guidance systems, Lempco serves major industries including canning, electronics, automotive, appliance, plastics, computer, and specialty items. The flagship product is the Rotainer®, a precision-designed ball cage that minimizes tracking.

Danly / IEM

Danly, incorporated in 1923, revolutionized manufacturing with a standardized guide post die set. Danly's "interchangeability" method, for the first time, made it possible for the die designer to layout their die with absolute certainty that they would fit in the Danly die set specified. Danly/IEM continues to set the standard for die and mold components. The Danly/IEM product set includes a wide range of guide posts, bushings, die springs, wear plates, cams, and other diemakers' supplies.

Lamina began as a lamination die manufacturer in 1938 and has since evolved into exclusively manufacturing die and mold components. Lamina is intimately familiar with die and mold makers' needs and objectives. Precision machined bushings, guide posts, wear plates, and cams comprise the core products. However, Lamina distinguishes itself with its hydraulic motors and equipment products. These products affirm Lamina's goal to fully support die maintenance.

Dayton Progress

Dayton Progress is the youngest of the companies, forming in 1946 as the Dayton Die Insert Company. In its first decade, Dayton introduced a standardized, engineer-focused punch catalog and the Firm Delivery Schedule. This delivery schedule was the first to bring speedy, "Just-In-Time" parts arrival to the punch industry. Dayton continues to lead the punch and die market with a complete selection of catalogs and technical brochures to help designers select the right die components. In-depth training programs are presented by knowledgeable Dayton field sales engineers.
