R&D and tooling engineers
Four product lines. One silicone platform.
Every product here starts as liquid silicone rubber on our own presses. We tool it, mold it, fit the electronics and test it in house. Bring a finished design, or start from one of our platforms and make it yours.

LSR injection molding, sealed around the electronics.
Liquid silicone flows around the circuit board, motor and heater, then cures into one continuous, seamless skin. There are no glue lines to split, nothing to trap moisture, and the surface feels soft against skin. That's why we build products that touch mothers and babies this way.

About Leutoo & the factory
07 / Buyer questions
Straight answers before you ask.
Can't find what you need? Email elvis@leutoo.com and an engineer will reply within one working day.
Q01 What is your minimum order quantity (MOQ)?
Our minimum order quantity is 2,000 pcs. That applies to private-label orders on our existing platforms and to custom ODM products with new tooling.
Q02 Who owns the molds and the design?
On custom projects, you can own the tooling and the product IP outright. We sign an NNN agreement (non-disclosure, non-use, non-circumvention) before we receive your drawings, and we never sell your design to other buyers.
Q03 What are your lead times?
New tooling takes 25–30 business days, after which T1 samples come off the press for your approval. Private-label orders on our existing platforms take about 25 business days. Stock samples ship in about a week.
Q04 Can you help with certifications such as CE, FCC or FDA registration?
Yes. We design for your target market from day one, supply the technical files and samples, and work with the accredited lab you choose. Our ISO 13485 system covers the manufacture of medical breast massagers, which supports medical-device registrations.
Q05 Do you provide samples before an order?
Yes. Stock samples of our existing platforms can ship within about a week. For custom projects, T1 samples come straight off the production tool, so you approve exactly what will be mass-produced.
Q06 Can we audit the factory?
Yes. Buyers and third-party inspectors are welcome on site in Changping, Dongguan, about an hour from Shenzhen and Guangzhou. We also offer live video tours of the lines.
