RTV Silicone (Room Temperature Vulcanizing)
- Condensation Silicone: Easy to use, ideal for beginners
- Addition Silicone: No by-products, perfect reproduction
- Shore A 20-30: Very flexible for complex silicone molds
- Shore A 40-60: Balance between flexibility and strength
Platinum Silicone - Premium Quality
- Highest quality: No inhibition problems with other materials
- Food safe: Safe for kitchen and baking applications
- Long life: Thousands of castings possible
- Transparent Options: For clear silicone molds
Special Silicone Types
- Fast systems: Curing in 30-60 minutes
- Slow systems: More processing time for large projects
- Heat resistant grades: Up to 300°C for special applications
- Colored Silicone: For recognizable and organizable molds
Professional Silicone Mold Techniques
1. One-Piece Silicone Molds
Ideal for simple shapes without undercuts. Perfect for beginners and quick projects.
2. Two-Part Silicone Molds
For complex 3D objects with undercuts. Requires more experience but delivers perfect results.
3. Block Silicone Molds
Material-saving technology for large objects. Efficient for series production.
4. Brush Silicone Molds
For highly detailed objects where every texture must be preserved.
5. Vacuum Silicone Molds
Professional technology for bubble-free, perfect silicone molds.
Step-by-Step: Making a Silicone Mold
- Object Preparation: Clean and prepare your original object thoroughly.
- Silicone Selection: Choose the right hardness and type for your application
- Building a Mal Box: Create a Sturdy, Leak-Proof Container
- Sleep aid: Apply suitable sleep aid to all surfaces
- Silicone Mixing: Mix components A and B in exact proportions
- Deaeration: Remove all air bubbles using vacuum or stirring technique
- Pouring: Pour slowly and evenly in a thin stream
- Curing: Allow to cure completely (6-24 hours depending on type)
- Demolding: Carefully remove the original object

Common Silicone Mold Problems & Solutions
Silicone does not harden
Solution: Check the mixing ratio, temperature, and humidity. Ensure a clean work environment.
Air bubbles in silicone mold
Solution: Use vacuum chamber, pour slower or use deaerator
Object sticks to silicone
Solution: Use more loose sleeping agent or choose a different silicone type
Silicone mold tears easily
Solution: Use more flexible silicone (lower Shore A) or make the mold thicker
Details are lost
Solution: Use lower viscosity silicone or brush technique for fine details
Pro Tips for Silicone Mold Experts
- Temperature Control: Operate at a stable temperature (20-25°C) for optimal results
- Inhibition Test: Always test compatibility between silicone and other materials
- Reinforcement: Use mesh or cloth for extra strength on large silicone molds
- Storage: Store silicone molds dry, clean and out of direct sunlight.
- Maintenance: Clean molds after use and check for wear.
- Documentation: Keep track of which silicones and settings work best
