Products used in this application:
In this plastic injection molding application, we look at how a simple plumbing modification can greatly improve the response time.
We are controlling air pressure into a bottle mold in a plastic injection process. A remote sense tube is plumbed in to the process to improve response time. The speed of response was improved by nearly 3 seconds (from 3.680 seconds to 0.880 seconds), filling a 20-gallon air volume to 5 psig.
The remote sense line provided the volume booster with feedback further downstream. This had two profound effects on the pressure:
1. Pressure was much more stable during the entire process.
2. Pressure was achieved much quicker in the bottle mold itself.
