DURA Core Collapsible Cores
Introducing DURA CORE, an innovative collapsible core solution: a ground breaking two-piece spring collapsible core designed for precision and longevity. This advanced collapsible core features a unique sequential collapse mechanism, where the larger and smaller segments operate independently. This distinct design ensures stress-free movement of the smaller segments, significantly enhancing the life-span of the DURA CORE.
Utilizing our exclusive patented design, every DURA CORE purposefully eliminates interaction between the larger and smaller segments throughout the collapsing process. This ground breaking characteristic not only prolongs the core’s durability but also promotes the production of premium quality parts.

FEATURES
Patented Two-Piece Design
The two-piece design of the DURA CORE is an innovative feature that significantly enhances the usability and maintenance of the collapsible core in injection molding.
Effortless Disassembly: Simplifies the process, enabling quick access to each component
Easy Inspection and Cleaning: Offers enhanced accessibility for thorough maintenance
Rapid, Secure Reassembly: Ensures quick and correct reassembly after maintenance
Minimize Maintenance Downtime: Reduces maintenance time, boosting production
Additional Design Features
Short Safety Ring: A compact safety ring, securely mounted on a safe plate
Straight Core Pin: The straight core pin design is a key element in optimizing both manufacturing and cooling. By facilitating more efficient cooling, it leads to improved overall performance of the core, enhancing the quality of the molded parts.
Reduced Overall Length: The DURA CORE’s reduced length offers considerable space-saving advantages. This design aspect is particularly beneficial in minimizing the mold base stack height, leading to more compact and efficient mold designs.
Compact Footprint: The core’s space-efficient design allows for more cavities in the same-sized molds or the same number of cavities in a smaller mold, thereby maximizing production output per cycle.
Multiple Segment Options
Depending On Part Geometry
The DURACORE can be designed with diverse segment options, providing design flexibility to ensure sufficient collapse for undercuts. The number of segments required is determined by the part size, part shape and the undercut. We offer options of 8, 10, 12, and 16 segments to accommodate a broad spectrum of part sizes, with diameters ranging from 15mm to 150mm.
