Resin Casting Calculator for Scale Modeling

Resin Casting Calculator for Scale Modeling

Calculate precise resin-to-hardener ratios, mold volumes, and material requirements for your casting projects

⚗️ Resin System & Mold Configuration

Different resin types have different mixing ratios and properties
Mixing ratio (Resin:Hardener). Common ratios: 1:1, 2:1, 3:1, 100:30
Typical resin density: 1.0-1.2 g/ml. Check your product specifications.

⏱️ Casting Parameters & Material Costs

Higher temperatures accelerate curing, lower temperatures slow it down
Curing & Demolding Times
Working time before resin starts to gel
Time until parts can be removed from mold
Advanced Settings
Account for pigment volume in calculations
Typical pigment: 1-5% of total resin volume

⚠️ Safety Precautions
  • Work in a well-ventilated area
  • Wear appropriate PPE (gloves, safety glasses)
  • Follow manufacturer's safety instructions
  • Dispose of materials properly according to local regulations

Always follow manufacturer's instructions for your specific resin system. These calculations are estimates.
