Redefining the Standards of Size

Through a complete reengineering of the internal structure and precise optimization of component geometry, we have achieved further downsizing and weight reduction while maintaining the same processing force as the White model.

A Cam Unit True to Fundamental Performance

Because cam units are widely used for piercing applications, we focused on a design that firmly adheres to the fundamentals. Durability, precision, and operability are all refined to a high level, ensuring stable processing quality.

Benefits of Introducing VALCAM‑XS

Interference Avoidance & Reduced Design Burden

In areas where conventional cam units often interfere—such as the rear section in wheel‑arch regions or where rear‑clearance space cannot be secured when positioned behind the back‑door inner window—VALCAM‑XS enables feasible layouts thanks to its exceptionally short front‑to‑back length. Even in challenging tooling design locations, VALCAM‑XS provides a practical solution.

Contributing to Reduced Die Weight

Because the front‑to‑back dimension is significantly shorter than that of conventional cam units, the seating area for the cam unit can be reduced, enabling a more compact die design and ultimately lowering overall die weight. In piercing operations for door inners and body‑side panels—where many cam units are typically required—the lighter body of the VALCAM‑XS further contributes to reducing the total die weight.

Improved Workability and Ease of Maintenance

Thanks to a simple guide structure using a copper‑alloy bush, the VALCAM‑XS achieves a cam‑slider weight of just 1.3 kg, which is 35% lighter than the VALCAM White. The total cam‑unit weight is kept below 4.0 kg for all angles. This lightweight design, combined with a highly serviceable assembly/disassembly structure, makes punch alignment and maintenance operations significantly smoother, greatly reducing operator workload.

High Reliability Specialized for Piercing

By efficiently distributing processing forces and enhancing durability through an optimized design, the VALCAM‑XS maintains the same level of processing performance as the VALCAM White—despite its compact size. In addition, the combination of a simple round guide using a proven copper‑alloy bush and a V‑guide structure ensures stable guiding accuracy and smooth motion. Its rigidity and stability remain uncompromised even at a smaller size, allowing safe and reliable use of the extended mounting‑surface option.

Maximizing Productivity in Progressive Die Operations

Progressive stamping dies are widely used for the mass production of automotive structural components such as front pillars, center pillars, roof rails, and side sills, as well as a variety of metal parts for home appliances, electronic devices, and industrial equipment. By integrating multiple processes, including piercing, bending, and forming, into a single die, progressive dies enable highly accurate and efficient continuous production. VALCAM-XS is a dedicated piercing cam specifically designed to maximize space efficiency. Its compact design minimizes both overall length and shut height to the greatest extent possible, allowing easy installation even in the limited space available within progressive dies. The cam also provides exceptional flexibility for complex process layouts where interference avoidance is critical, contributing to more effective utilization of die space and reduced die design time. In addition, VALCAM-XS combines outstanding durability, precise operating performance, and excellent maintainability, making it a powerful solution for the high-volume production of automotive structural components and a wide range of other metal parts.
