This is a normal physical phenomenon. Bubbles form during mixing and must be removed through vacuum exhaust treatment.

Product Q&A

Q:What types of silicone products do you manufacture?

We manufacture liquid silicone, silicone rubber, and silicone oil. We offer different viscosities, hardness, and density to meet specific client requests.

Q:Do you provide free samples for testing?

Yes, we can provide free samples for clients to test before placing an order.

Q:How do you control product quality?

We have a professional QC team that controls quality during production. All goods are 100% inspected before shipment.

Q:How can I remove bubbles during mold making?

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

Q:How can I make my silicone mold last longer?

Choose the right liquid silicone, avoid using silicone oil which makes molds too soft, and wait 2 hours after the mold is finished to ensure it is fully cured.
