Product Q&A

Q:What types of silicone products do you manufacture?

We produce liquid silicone, silicone rubber, and silicone oil. Our silicone viscosity, hardness, and density vary to meet specific client requests for different mold applications.

Q:Do you offer free samples to clients?

Yes, we can provide free samples for testing purposes to ensure the product meets your requirements.

Q:How is quality control managed in your factory?

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, place the mixture into a vacuum machine to remove the bubbles effectively.

Q:How can I ensure the silicone mold lasts longer?

Choose the right liquid silicone for your product, avoid using silicone oil as it makes molds too soft, and allow the mold to fully cure for at least 2 hours after finishing.
