More options more capabilities. The New DME Collapsible 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.

The DME S-Cores can be manufactured in multiple variations depending on part geometry.
Three (3) large and three (3) small slide segments each. Provides sufficient collapse for undercuts up to 600mm.
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.
The smallest possible collapsible core available. Design optimized for producing undercuts on diameters as small as 6mm.
The DME S-Core Rack System allows for cores to be placed closer together by utilizing a common retaining ring. This is an important feature when space in the mold is limited. This allows designers to create smaller molds to run on smaller presses – saving time and money. Rack systems can be made with up to 8 cores and a minimum spacing of 30mm, however this is dependent on the size of the product being produced and the required under cut depth.
DME can provide the DME S-Core ready to install with the complete thread or undercut detail already machined in, however in some cases customers like to complete this detailed work. The new DME S-Core is designed with a flat bottom. When the core is positioned flat it is at location “zero” or “molding position” allowing for ease of setup to perform final machining or EDM.
NOTE: Manufacturing fixture available upon request at no additional cost when purchasing all DME S-Cores.
When designing your mold base for a given product many of the choices of materials and components are based on the expected life cycle/required part count of the mold. If the mold is to be ran for years to come or you are simply trying to maximize the cycles between PM, adding DLC (Diamond-like-carbon) coating to your DME S-Core you will obtain a superior component that will last. DLC is an amorphous carbon layer that provides a very high hardness and an extremely low friction coefficient providing the following benefits: extends the life of the core, reduces the resins ability to adhere to the core and protects the core from corrosion caused by exhaust gases.
Up to 8 cores can be racked as close as 30mm apart depending on part size. Providing less footprint required ultimately reducing the overall mold base/press size required.
