Silicone baby bottle injection mold

The silicone baby bottle injection mold is developed for producing high-precision baby bottle components made from liquid silicone rubber. The mold is suitable for manufacturing silicone bottle bodies, nipples, feeding valves, straws, and sealing accessories with stable dimensions and excellent surface quality.

Liquid silicone rubber is widely used in maternal and infant products because it is non-toxic, odorless, soft, and resistant to high temperatures and tearing. Compared with traditional rubber materials, LSR offers higher transparency, better flexibility, and improved product consistency, making it an ideal material for baby feeding products. TYM provide the LSR injection machine and mold for silicone baby bottle.

Mold Information

Mold Design & Technology

The Silicone baby bottle injection mold is engineered with advanced liquid silicone rubber (LSR) injection molding technology to support the production of high-precision silicone baby bottles, nipples, valves, and feeding accessories. The mold adopts a cold runner system with accurate temperature control to prevent premature curing of silicone materials and reduce raw material waste during mass production.

For complex baby bottle structures and high sealing requirements, the mold can be designed with needle valve gate technology, vacuum venting systems, and multi-cavity configurations to improve silicone flow balance, reduce flashing, and ensure stable molding quality. Precision parting line control and polished mold cavities help produce transparent and smooth silicone products with excellent dimensional consistency.

The mold supports overmolding solutions for combining liquid silicone rubber with PP, PPSU, or other plastic materials commonly used in baby bottle manufacturing. It can be integrated with automatic vertical LSR injection molding machines, robotic arms, and automatic demolding systems to establish a fully automated production line with high efficiency and low labor costs. 

FAQs

Q1: What machines are needed to produce a complete set of silicone baby bottles?
A: It need the LSR injection molding machine to produce the silicone baby nipple and silicone bottle, the plastic injection machine to produce the PP cap, PP screw ring, PPSU/PP screw.

Q2: One LSR machine can produce the baby nipples and silicone bottles?
A: YES, the 130T LSR machine TYM-W5050 can produce the baby nipples and bottles, which only need change the molds.

Q3: What's a day's capacity for the baby nipple?
A: The different design and cavity, the capacity will be different, more details please contact to us.
