Pressing or joining is one of the most common manufacturing operations. Leaks, unwanted noise and other defects found downstream on production lines are often due to missed issues during the pressing process. That makes utilizing the right press monitor critical.

Sciemetric applies advanced digital process signature technology to monitor every step of the press force operation to catch defects accurately and reliably, as they occur.

sigPOD adds intelligence to your press-fit operations

Sciemetric’s sigPOD delivers an unbeatable combination of price, functionality, and performance far beyond the typical window and postage-stamp analysis of other press-fit monitoring systems. It uses unique digital process signature analysis software to capture, analyze, and store thousands of data points from each pressing operation to deliver the most accurate real-time defect detection.

sigPOD works with any hydraulic, servo electric, air over oil, and mechanical presses.

Finds part issues

  • Incorrect orientation
  • Cracked
  • Over-size
  • Under-size
  • Improper insertion
  • Tolerance stack-up

Identifies process or machine issues

  • Bad alignment
  • Improper lubrication
  • Wrong ram speed
  • Loose fixtures
  • Damaged seals
  • Low hydraulic pressure

Digital signatures provide greater accuracy in force distance monitoring

Sciemetric force distance monitoring technology is based on digital process signatures, or waveform analysis, which analyzes all the critical points of an operation to determine a pass/fail decision. Signature analysis provides a visual representation of the process.

The force distance waveform is a combination of force vs. time and distance vs. time measurements.


The combined press signature provides a visual overview of the key measurement parameters.

Variations in the repeatable curve are indications of problems. Only Sciemetric enables the reprocessing and overlay of signatures to determine the root cause of issues. For example, looking at a population of signatures, the chatter seen can be attributed to spikes in force caused by the rocking of the pin being inserted during the operation.
