Mold Cooling & Thermal Control Tools
Cooling Time estimates the polymer-side timing; this workflow evaluates cooling-circuit flow, average heat removal and validation.
From part cooling to measured circuit evidence
Cooling Time → Mold Heat Removal → Required Flow → Reynolds Number → Water Temperature Rise → Chiller Capacity → Circuit Comparison → Measurement Validation.
Required Cooling Circuit Flow Rate Calculator
Estimate flow required to reach a target circuit Reynolds number.
Mold Heat Removal Calculator
Estimate average heat removal from the complete cooled shot.
Cooling Water Temperature Rise Calculator
Predict coolant outlet rise from a heat load and measured or specified flow.
Injection Molding Chiller Size Calculator
Estimate required process cooling capacity without double-counting base load.
Cooling Circuit Balance Comparison Tool
Screen one measured cooling circuit for velocity, Reynolds number and heat removal.
Guides for decisions and validation
Turbulent Flow in Injection Mold Cooling
Laminar, transitional and turbulent cooling-circuit flow; Reynolds targets and fluid-property limits.
Series vs Parallel Mold Cooling Circuits
How circuit arrangement, flow distribution and balancing affect mold cooling.
Mold Cooling Measurement and Validation Checklist
Connect stable-state mold measurements to thermal-control calculator inputs.
Use one base process load in chiller sizing: either a polymer/process estimate or a measured circuit load. Do not add both. Validate glycol condition, leaving-water temperature, ambient/condenser conditions, altitude, fouling, pump limits and actual flow before selecting equipment.
