Sprung Core Ø6x6,2x175

Since 1995, CUMSA has led the development of Sprung Core solutions for releasing small undercuts in injection molds.

The new PZ represents the culmination of more than three decades of innovation and continuous improvement, combining the key advantages of the PX and PW models into a single, optimized product:

• g6 tolerance precision
• Integrated head-regulation system for easier installation
• Compatibility with the AP Retractable Core Extension for larger applications
• Improved versatility and performance
• Lower machining requirements
• Compact system that takes up the space of an ejector pin

The PZ represents the natural evolution of our sprung core technology, delivering greater efficiency while simplifying selection and application.

The result is a more versatile, efficient, and cost-effective sprung core, engineered to meet today’s mold making challenges.
