Sensors for Resin Infusion

Sensors for Resin Infusion

SensorWhy?
Vacuum Sensor
  • Our vacuum sensor has a resolution of 0.1 inHg, so you’ll spot changes instantly—vital for saving time and avoiding costly issues
  • Preparation – Record your drop test to spot leaks early and measure slow vacuum loss. For large, high-value parts, we recommend heating the mould during the drop test to simulate the exothermic reaction, revealing hidden issues before they emerge during cure.
  • Infusion – Monitor bag integrity whilst you infuse. Alerts warn you the moment a leak develops—long before you’d spot it unaided. It’s excellent QA data too, ready for customer inspection.
  • Curing – Issues can still develop during the cure, and if you miss them you may not get the part you want. You need vacuum integrity until the gel-stage. As the exotherm builds, warnings and alerts let you understand any shifts in vacuum. The automatic pump controller can turn your pump on if necessary to support your vacuum. View everything remotely via the online portal: especially handy for overnight cures or when managing multiple parts.
Temperature Probe (bucket) – our standard -50 °C to 125 °C probe.
  • Monitor resin temperature in your bucket and act fast. Having a run-away exothermic reaction can easily complicate or ruin an infusion. Warnings and alerts means you can catch this far sooner. You can either infuse faster, change resin, or stop. Even stopping saves you your time spent on the job.
  • Monitor resin temperature in your degassing chamber. This protects you from an exothermic reaction due to the time a degas can take (especially if it's a larger infusion). It's our experience that a full degas can take up to 40 minutes. We recommend slower hardeners for long degas times. For fast systems, you can infuse as soon as the exotherm starts—just be quick about it. For a partial degas on a faster resin system, you can degas until you detect your exotherm starting and then infuse. We would only recommended this if you have a quick infusion.
Temperature Probe (on your mould)
  • **Mould control** Your resin’s TDS gives a target temp (typically ~30 °C). If your mould is too cold, the resin thickens, struggles to wet the fibres, and traps air. This invites both cosmetic flaws and structural issues. Sometimes we check surface quality with a microscope.
Barometric Sensor (Extended Set)
  • Your barometric sensor also has a resolution of 0.1 inHg – ideal for compensating vacuum readings.
  • Significant weather changes (such as a 3% weather drop during a storm) can look like a leak. Barometric compensation ensures you have the full picture with your vacuum readings, and avoid false negative readings.
Ambient Temperature Probe (Extended Set)
  • Monitor Ambient Temperature so you know if it will affect your infusion. It matters more than you may think. Too cold? Warm your mould and resin. Too hot? Choose a different hardener, or delay the job. Ambient monitoring also helps you compare historic runs to spot anomalies.
Additional Temperature Probes (Extended Set)
  • Multiple probes unlock visibility across your mould, stack and oven.
  • Mould: understand temperature uniformity. Cold patches can slow the resin front and wreck an infusion, or at least mean you are having to infuse more resin than you want – adding to complexity and cost.
  • Stack: track your cure cycle through large or complex layups. Some zones cure faster than others.
  • Oven – Ovens often have hot and cold spots. Mapping these ensures even curing and even better parts. We have seen poor oven performance ruin parts.
Energy Sensor (Extended Set)
  • You can monitor the cost energy consumed by your heaters, oven etc. This means you have a more accurate view on your costs, and can price accordingly. This highly valuable data (by job-id) helps protect margins.
