Force plotting allows companies like yours to determine how much force was required to perform a process. Using a LabVIEW-based system with force and positional feedback, Innovative can create force profiles to identify assembly issues or missing components. This technology is typically integrated with a servo slide and a separate linear encoder.
For example, on one of our machines, the force resolution was so fine that we were able to detect flash on plastic molded parts when they were pressed together.
This system used a servo-slide with a linear encode and a force transducer.
The product was compressed and the force vs. distance was recorded every 1 micron.
The limit boundary’s allowed the test system to detect incorrectly placed springs, excessive material flash and a minimum “snap” force that was critical to the product function.
The green and blue lines are the limit windows. This example shows a bad part where the white sample data exceeds the boundaries
This is an example of a good part force profile
Small zero-clearance die sets punch out foils, membranes, screens that can be heat staked during placement.
Our technique to deal with highly charged materials is to never loose control of the material. We hold the parts with vacuum as they are punched
