Other Collapsible Cores
THE DME S-CORES CAN BE MANUFACTURED IN DIFFERENT VERSIONS. The DME S-Cores can be manufactured in multiple versions depending on part geometry. The DME S-Core Dovetail Cores allow for: simplified smaller molds, faster cycle times, improved part quality and reduced mold maintenance over traditional devices. It also helps reduced mold maintenance over traditional unscrewing devices. Making it a better choice for your threading or undercut application. More options more capabilities. The New DME S-Core is a dynamic design that can be produced in 6, 8 or 12 segments enabling parts to be produced as small as 6mm and as large as 400mm. The length and depth of the part feature dictates the number of segments required to release the undercut. DME Engineers will review each part model and design a DME S-Core for your specific application. Each DME S-Core utilizes patented safety stops preventing the folding segments from touching each other during ejection or over travel. This results in a longer lasting collapsible core that produces higher quality parts.

DME S-CORE WITH PATENTED SAFETY STOP
6 Segments Three (3) large and three (3) small slide segments each. Provides sufficient collapse for undercuts up to 600mm.
DME S-Core Safety Stop protects the folding segments from colliding when fully opened or over traveled.

Collapsed for Ejection
12 Segments The smallest possible collapsible core available. Design optimized for producing undercuts on diameters as small as 6mm. 8 Segments Four (4) large and four (4) small slide segments each. Used for intermediate (medium) undercuts. DME S-Core’s can be designed in Oval and Square shapes to compensate for part deformation/shrink.
• Unlike other products on the market, the DME S-Core has safety stops built into the corners of the folding segments to prevent them from colliding with one another in the event of over travel. • The safety stop is incorporated in all of the folding core segments in the head area (between the three retaining rings). • Folding segments are made from 420 stainless steel and the center guide is made from H13. • Safety stops come standard on all DME S-Cores.
