Yes, we can provide samples for testing.
3. How is quality controlled in your factory?
We have a professional QC team. Every batch undergoes testing through our safety quality examination system.
4. How to remove bubbles during mold making?
After mixing liquid silicone with curing agent, place the material in a vacuum machine to remove bubbles.
5. How to make silicone molds last longer?
- Choose the right liquid silicone for your product
- Avoid using silicone oil in mold making as it softens the mold
- Allow molds to fully cure for 2 hours after completion
6. Why does silicone rubber develop bubbles after mixing with curing agent?
