Advanced Solution for Moulding Threads and Undercuts
DURA CORE is an innovative collapsible core solution: a groundbreaking 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 lifespan 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 groundbreaking characteristic not only prolongs the core’s durability but also promotes the production of premium quality parts.
DURA CORES, with their compact design and shorter safety ring, enable effortless cleaning and maintenance. The innovative construction enhances cooling, reduces the overall length, and results in a more compact footprint. Ultimately, the DURA CORES lead to the creation of smaller, simplified molds and elevate part quality.
The DURA CORE’s two-piece design drastically reduces collapsible core maintenance, a common challenge with traditional spring collapsible cores. For threading or undercut applications, the DURA CORE stands out as the superior choice, offering efficiency, quality, and reliability.
