This is a normal physical phenomenon. Liquid produces many bubbles during mixing, so vacuum exhaust bubble treatment is required.

Product Q&A

Q:What types of silicone products do you manufacture?

We produce liquid silicone, silicone rubber, and silicone oil. Different viscosities, hardness, and densities are available to meet specific client requests.

Q:Do you provide free samples?

Yes, we can provide samples for testing purposes.

Q:How do you ensure product quality?

We have a professional QC team controlling 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, place the material into a vacuum machine to remove the bubbles.

Q:How to extend the lifespan of silicone molds?

Choose the right liquid silicone, avoid using silicone oil (which makes molds too soft), and wait 2 hours after finishing the mold to ensure full curing.
