The Challenge: A Delicate Marking Problem
Our customer’s existing process for date coding film negatives used heat, which was inconsistent and risked damaging the delicate material. They needed a permanent, legible marking solution, but found that off-the-shelf equipment and high-tech marking systems were not a perfect fit. The challenge wasn’t just about marking; it was about protecting a fragile product while ensuring a reliable, repeatable result for a mission-critical process.

The Numberall Solution: Engineering a Tailored Process
While other companies might offer a generic machine and hope it fits, our process begins with understanding your specific problem.
Before providing a quote, we conducted extensive in-house testing using our customer’s film samples. Our goal was to find a process that worked perfectly. We tested stamping without heat, and our results proved that a clear, legible impression could be made without any distortion to the negative. This crucial discovery allowed us to develop a specialized, non-destructive solution that other technologies may have overlooked.

We understand that time is critical. Our process from preliminary quote to custom solution takes as little as two weeks, and we provide a response to your initial request within 24 hours.
The Custom-Engineered Components: Simplicity & Reliability
To create a machine that would work perfectly for this delicate application, we integrated our dependable, US-made components with a custom-engineered design:
- Custom Fixture & Pneumatic Automation: This is where our engineering truly provided value. We created a special fixture that used pneumatic gap sensors to automate the stamping cycle. The operator simply places the film, and the machine cycles automatically. This simple, elegant solution removed the need for complex electric switches, ensuring an efficient, foolproof process.
Model 136A Air-Operated Press: We chose this compact bench-top press for its reliability and controlled force. Unlike more complex, high-tech machines, the pneumatic operation was ideal for the fragile material.

Model 70P Numbering Head: This versatile head was a perfect fit for the repetitive nature of date codes, providing consistent character alignment and impression depth without constant operator adjustments.
