FAQ
1. What silicone products do you manufacture?
We produce liquid silicone rubber, silicone rubber, silicone oil, and platinum agents. Our silicone products vary in viscosity, hardness, and density to meet specific client requirements.
2. Do you offer free samples to clients?
Yes, we can provide samples for testing.
3. How is quality controlled in your factory?
We have a professional QC team and each batch undergoes our safe quality examination system.
4. How to remove bubbles during mold making?
After mixing liquid silicone with curing agent, place the material into a vacuum machine to remove bubbles.
5. How to create durable silicone molds?
Choose the right liquid silicone for your product, avoid using silicone oil (which softens molds), and allow molds to fully cure for 2 hours after completion.
6. Why does silicone rubber develop bubbles after mixing with curing agent?
This is a normal physical phenomenon. The liquid produces bubbles during mixing and requires vacuum treatment for bubble removal.
