DME S-Core Premium Collapsible Cores

The Next Level of Undercut Solutions

Featuring

  • Patented Safety Stops
  • Oval & Rectangular Designs
  • Wide Range of Diameters
  • Stackable

Advanced Solution to Molding Threads & Undercuts

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.

Advantages Over The Competition

The DME S-Cores can be manufactured in different versions

The DME S-Cores can be manufactured in multiple variations depending on part geometry.

6 Segments

Three (3) large and three (3) small slide segments each. Provides sufficient collapse for undercuts up to 600mm.

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.

12 Segments

The smallest possible collapsible core available. Design optimized for producing undercuts on diameters as small as 6mm.

DME S-Core With Patented Safety Stop

  • 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.

DME S-Core Retaining Rings

Want to produce more parts in a smaller space?

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 S-Core Adding Detail Made Easy

Flat bottom delivers easier assembly

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.

DME S-Core Styles Examples

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.
