AI-Powered supplier vetting

SummaryGuangzhou OTT New Materials Co., Ltd. is a China-based limited company established in 2014, operating in silicone and related chemical materials. It reports five production lines, a 1,700 m² manufacturing plant, broad product coverage, exports representing 90% of total sales, and stated peak- and off-peak-season fulfillment within 15 working days. The supplier holds ISO 9001:2015 certification and describes technical support, after-sales service, and silicone-material innovation capabilities. However, the available information indicates a relatively small organization of 17 employees, fewer than five quality-control staff, and limited documented customer-trade evidence. Financial strength, customization performance, and the depth of customer cases cannot be conclusively assessed from the provided data.

Production capacityThe supplier reports five production lines, a 1,700 m² manufacturing plant, and order fulfillment within 15 working days in both peak and off-peak seasons. Its product scope is broad and export sales are stated to represent 90% of total sales, but the small total workforce of 17 employees and fewer than five quality-control staff indicate that operational scale should be verified for large-volume requirements.

Product Q&A

Q:What types of silicone products do you manufacture?

We produce 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 the product quality.

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 mixture in a vacuum machine to remove the bubbles.

Q:How can I make silicone molds last longer?

Choose the right liquid silicone for your product, do not use silicone oil (which makes molds too soft), and wait 2 hours after the mold is finished to ensure full curing.
