Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Resin Cast Volume Planner
Plan a rectangular casting’s resin volume and mix masses from supplied density and ratio.
- Enter length, width, depth, density, a parts by mass, b parts by mass using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Length: 20 centimeters Width: 15 centimeters Depth: 0.5 centimeters Density: 1.1 grams per milliliter A parts by mass: 2 parts B parts by mass: 1 parts Total volume · milliliters: 150 Total mass · grams: 165 Part A · grams: 110 Part B · grams: 55
Questions & answers
What does Resin Cast Volume Planner calculate?
Plan a rectangular casting’s resin volume and mix masses from supplied density and ratio.
Which units should I enter?
Length uses centimeters. Width uses centimeters. Depth uses centimeters. Density uses grams per milliliter. A parts by mass uses parts. B parts by mass uses parts. Convert values to these units before calculating.
Which formula does it use?
Volume = length × width × depth; mix ratio is by mass, not volume.
What does the included example show?
Length: 20 centimeters; Width: 15 centimeters; Depth: 0.5 centimeters; Density: 1.1 grams per milliliter; A parts by mass: 2 parts; B parts by mass: 1 parts. Result: Total volume · milliliters = 150; Total mass · grams = 165; Part A · grams = 110; Part B · grams = 55.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
