HELM INSTRUMENTS

ABOUT THE COMPANY... Founded in 1962, Helm Instrument Company is the leading designer and manufacturer of process control systems, force transducers and software for the metalforming industries.  Helm introduced press load monitoring and signature analysis in 1968, in-die force sensing in 1972 and holds numerous patents on sensor designs, instrumentation and applications.  From our strategic location in the industrial Midwest, we supply and support our customers with a complete staff of representatives worldwide.

Automatic Die Monitoring

Misfeeds, pulled slugs, double hits, or broken punch assemblies cost time and money.  These abnormal conditions are eliminated with the Micron die monitoring system.  Non-contacting, proximity sensors monitor deviations in stripper position or die height to within 0.00004 inches (1/1000mm).

Signature Analysis Software

Analyzing the forming signature on a specific tool is critical to in-process quality control.  The Helm FirstMate® software provides two-way communication between the Helm force monitoring system and a lap-top or remote computer.  Available in Windows 3.1, 95 and NT operating systems, FirstMate will generate the necessary statistical data, graphical waveforms and downtime event reporting for real-time analysis of the production process.
