DME was founded to help streamline the manufacture of plastic injection molds. In 1942, Ted Quarnstrom began Detroit Mold Engineering (later to become DME Company) to provide mold bases in standard sizes, ready for machining of the cavity. This innovation empowered the skilled moldmaker to practice his craft more efficiently and the concept of the standard mold base was born. DME is focused on one thing - to help make moldmakers, molders and mold designers produce better parts. Every DME product cuts costs, reduces time-to-market or improves the finished molded product (sometimes all three). Today, the DME product line encompasses a wide range of products, including: Mold bases, DME standard, custom-machined, Edge and MoldBasics series, plus Master Unit Die (MUD) quick change(tm) mold systems and components

U.S. injection molders are still pretty green when it comes to processing the new crop of renewably sourced biopolymers. These biologically derived polymers made from PLA, PHA and starch-based resins are attracting growing market interest as materials with no ties to petrochemical-based thermoplastics.
Five new sizes have been added to the standard line of collapsible cores from D-M-E Co., Madison Heights, Mich.
Interlocks that ensure accurate alignment and guidance of the mold halves are new additions to the line of D-M-E Co., Madison Heights, Mich.
The accepted ground rule for balancing melt flow in multi-cavity injection molds is to achieve equal flow distance from the injection point to each cavity.
Injection mold cost savings, greater molding productivity, and better part quality are promised for a new ejection system that does away with conventional ejector plates, housings, pins, and risers. This approach is said to reduce mold height, shorten mold-open times by at least 10%, enable better optimization of mold cooling—not to mention eliminating ejector marks on parts.
WEB EXCLUSIVE D-M-E Co., Madison Heights, Mich., has formed a strategic alliance with Futaba Corp., a major Japanese supplier of mold bases and components.
A new ejection system that eliminates the ejector plate, reduces mold height, leaves no ejector marks on parts, shortens cycle time, and allows better optimization of cooling lines comes from D-M-E Co., Madison Heights, Mich.
A cold-runner system designed for liquid silicone rubber as well as high-temperature-vulcanizing silicone rubber and other elastomers is being introduced in North America by D-M-E Co., Madison Heights, Mich.
