This is a normal physical phenomenon where the liquid produces bubbles during mixing; it must pass through vacuum exhaust treatment.

Product Q&A

Q:What silicone products do you make?

We produce liquid silicone, silicone rubber, and silicone oil. Our silicone varies in viscosity, hardness, and density to meet specific client requests.

Q:Do you offer free samples?

Yes, we provide free samples for testing, but the customer must bear the international shipping cost.

Q:How is quality controlled in your factory?

We have a professional QC team that inspects goods 100% before shipment to ensure quality.

Q:How do I remove bubbles during mold making?

After mixing the liquid silicone with the curing agent, place the material in a vacuum machine to remove the bubbles.

Q:How can I get a silicone mold to last longer?

Choose the right silicone for your product, avoid using silicone oil as it softens the mold, and wait 2 hours after finishing the mold for full curing.
