Product Q&A

Q:What silicone products do you manufacture?

We produce liquid silicone, silicone rubber, and silicone oil. Different molds require specific viscosity, hardness, and density to meet client requests.

Q:Do you offer free samples?

Yes, we can provide samples for testing purposes.

Q:How is quality controlled in your factory?

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

Q:How to remove bubbles during mould making?

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

Q:How to get a good silicone mould for longer use?

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