TECHNICAL KNOWLEDGE CENTER
Practical guidance for vacuum-based composite manufacturing.
Process guides, measurement notes and quality documentation resources developed around the real-world use of vacuum in resin infusion, vacuum bagging and advanced composite manufacturing.
DVS RESOURCE LIBRARY
From vacuum integrity to instrument traceability.
These resources are intended as practical technical guidance. Where a customer process, drawing, specification or quality system defines a requirement, that controlling documentation takes precedence.
PROCESS GUIDES
Vacuum process verification
Practical methods for checking bag integrity, troubleshooting leaks and choosing useful measurement points.
How to Perform a Vacuum Drop Test
A step-by-step approach to stabilizing, isolating and monitoring a vacuum system before comparing the result with the controlling process requirement.
Read guide → PROCESS GUIDEFinding Vacuum Bag Leaks Faster
A systematic troubleshooting method for perimeter seals, pleats, fittings, hoses, valves and other common leak sources.
Read guide → PROCESS GUIDEGauge Placement on Large Vacuum Bags
Considerations for gauge location, long hose runs, multiple measurement points and repeatable vacuum verification on larger parts.
Read guide →TECHNICAL NOTES
Understanding vacuum measurement
Clear explanations of the concepts behind vacuum readings and gauge specifications.
Digital vs. Analog Vacuum Gauges
A practical comparison of readability, resolution, operator interpretation and process use.
Read note → TECHNICAL NOTEUnderstanding inHgV
What inches of mercury vacuum means, why the number increases as vacuum deepens and how atmospheric pressure affects interpretation.
Read note → TECHNICAL NOTEResolution vs. Accuracy
Why these two specifications are different and why both matter when evaluating a vacuum gauge.
Read note →QUALITY & DOCUMENTATION
Traceability and verification
Documentation behind the DVS-G build record, serialized components and final functional verification.
DVS-G Component Traceability
How serialized sensor assemblies, supplier documentation and finished gauge serial numbers connect within the product record.
