CUMSA

The CU is a 100% mechanical mechanism designed specifically for parts with intricate geometries and difficult-to-eject undercuts. By eliminating external power systems, it offers a clean, reliable, and maintenance-free alternative that reduces risk while improving long-term mold performance.

Mounted directly on the cavity side of the mold, the CU allows for easy setup, adjustment, and inspection. Its modular design ensures compatibility with both new and existing slides, making it a versatile option for standard molds as well as fully customized configurations.

One of the CU’s key strengths is its movement flexibility. The system supports both straight and angled slide movements, enabling precise adaptation to complex part geometries. Available in a universal size, it simplifies sizing and integration across a wide range of applications.

Beyond simplifying design, the CU enhances production reliability. By preventing molds from remaining open, it ensures a smoother production flow while improving operational safety on the shop floor.

Compact, intuitive, and highly adaptable, the Cavity Undercut transforms how complex undercuts are managed. By reducing maintenance requirements and eliminating unnecessary systems, it minimizes downtime and extends mold longevity—proving that even the most complex challenges can be solved with smart mechanical design.
