New Dovetail Collapsible Core

Roehr has expanded its product line with the addition of the new Dovetail Collapsible Core
(DT Core).

The DT Core offers the following benefits:

·   Can be removed while the mold is
in the press

·  Gradual release from undercut

·   Large, robust segments

·   Compact height

·   Reliable shut-off with front half of mold

·   Customizable collapse angles

·   Shorter stroke on mold staging

·   Deeper undercuts

·   Taller parts

·   Constructed from high quality materials
including A2 steel.

“With our new Dovetail Collapsible Core technology, customers are able to design and build a mold that requires only “Mold Open, Mold Close” to operate,” explains Dave Helenius, senior applications engineer at Roehr.  “In most cases there is no need for special core pull circuits or even the common ejector plate sequence. The potential cycle time reduction is enormous. 

“Combine our Dovetail Collapsible Cores with our new, patent-pending quick lock system and customers are able to quickly remove the Dovetail Core assembly from the mold without removing the mold from the machine,” he continues.  “That’s impossible with a rack and gear mold.”

Roehr Application Partner: Custom Mold

Roehr continues to hear from mold builders about how their customers have benefitted by using Collapsible Core technology.  This account, provided by Custom Mold & Design in Minneapolis, MN, provides evidence of several advantages gained by a customer new to the technology. 

Mark Casey, a member of the management team at Custom Mold, told us about a customer that wanted not only to optimize cycle times, but there were concerns about space issues and press size as well. 

“Our customer requested a two-cavity unscrewing mold to fit into a specified press size but the part is large enough that there was a concern about fitting the mold, with rack and gears, into that press size,” explained Casey.  “So, knowing the benefits Collapsible Cores offered, we suggested using them for this project and the customer was willing to try them. 

“The part design was altered slightly, but the customer liked the simplification of it and, in the long run, it also resulted in less maintenance issues for them, not to mention a 20% improvement in cycle times versus an unscrewing system,” Casey continued.  “We were able to provide a lesser cost tool that runs more efficiently, requiring less maintenance and less downtime.  That’s significant.”
