Rubber Mold Materials Overview
Silicone Rubber Molds
- RTV Silicone: Room temperature curing, perfect for beginners
- Platinum Silicone: Highest quality, no inhibition problems
- Tin Silicone: Cost-effective for simple rubber molds
- Shore A 20-40: Very flexible for complex shapes
- Shore A 50-70: Balance between flexibility and strength
Polyurethane Rubber Molds
- Flexible PU Rubber: Stronger than silicone, excellent wear resistance
- Shore A 30-60: Different hardnesses for specific applications
- Fast systems: Curing in 15-30 minutes
- Transparent grades: For visual control during pouring
Special Rubber Types
- Food-safe rubber: For kitchen and baking applications
- Heat resistant rubber: For high temperature applications
- Chemical resistant: For aggressive casting materials
- Latex rubber: For thin, highly flexible molds
Professional Rubber Mold Techniques
1. One-Piece Rubber Molds
Ideal for simple shapes, fast production and beginners.
2. Two-piece Rubber Molds
For complex 3D objects with undercuts and high precision requirements.
3. Block Rubber Molds
Material-saving technology for large objects and series production.
4. Brush Rubber Molds
For highly detailed objects where every texture must be preserved.
5. Mother Mal System
Support for large rubber molds to prevent deformation.
Step-by-Step: Making a Rubber Mold

Common Rubber Mold Problems & Solutions
Rubber mold tears quickly
Solution: Use more flexible rubber (lower Shore A) or make the mold thicker
Object sticks to rubber
Solution: Use more loose sleeping agent or choose a different rubber type
Air bubbles in rubber mold
Solution: Use vacuum chamber or pour in a thin stream from a height
Rubber does not harden properly
Solution: Check mixing ratio, temperature and humidity
Details are lost
Solution: Use lower viscosity rubber or brush technique
Pro Tips for Rubber Mold Experts
- Temperature Control: Operate at stable temperature (20-25°C) for best results
- Rubber Compatibility: Always test compatibility with your casting material
- Reinforcement: Use mesh or cloth for extra strength on large rubber molds
- Storage: Store rubber molds dry, clean and out of direct sunlight.
- Lifespan: Keep track of how many castings you've made for maintenance planning
- Repair: Small cracks can often be repaired with liquid rubber
