China Custom Baby Bottle Nipples Manufacturer

We manufacture silicone baby bottle nipples for brands developing replacement products or expanding an existing bottle line. You can select an available design or develop a custom nipple based on your approved sample and functional requirements.

EXISTING PRODUCT RANGE

Baby Bottle Nipples in 50 60 and 73 Caliber Series

The Silicone Baby Feeding Set comes in six configurations, from a 4-piece starter to an 8-piece set — all in one matched five-color system, at a low 500-piece MOQ per configuration.

50 Caliber Baby Bottle Nipples

The 50 caliber range includes a conventional baby bottle nipple, a flatter drinking-spout structure and a raised outlet for straw connection. Matching straight and weighted straw components are also available. This gives you several feeding structures within the smaller caliber category, whether you need a standalone replacement nipple or a straw-compatible product.

60 Caliber Baby Bottle Nipples

60 Caliber Baby Bottle Nipples

The 60 caliber range provides several rounded silicone baby bottle nipples with different upper profiles, including conventional nipple and straight-outlet designs. Compatible long-straw and weighted-straw components expand the range beyond standalone nipples, allowing you to source both standard feeding and straw-compatible products within the 60 caliber category.

73 Caliber Baby Bottle Nipples

73 Caliber Baby Bottle Nipples

The 73 caliber range combines wider-flange baby nipples with rounded nipple, tapered spout and straight-outlet profiles. Assembled nipple-and-straw combinations are also available. For wider-neck bottle projects, this series gives you both standalone replacement nipples and complete straw-compatible structures without limiting the range to one nipple shape.

REPLACEMENT PRODUCT OPPORTUNITY

Add Replacement Baby Bottle Nipples to Your Existing Bottle Line

Offer standalone replacement nipples for changing feeding needs without requiring customers to purchase another complete bottle.

Sell the Nipple as a Separate Product

Many customers want to retain the bottle body and collar while replacing only the nipple. Adding standalone baby bottle nipples allows you to meet this demand with a lower replacement cost than purchasing another complete bottle. It also extends the commercial life of your existing bottle range by adding a continued accessory sales opportunity.

Cover Changing Feeding Stage Requirements

As feeding volume and sucking ability change, the same bottle may require nipples with different flow characteristics. You can develop silicone baby bottle nipples with different milk-opening shapes, opening sizes or nipple structures for each planned stage, allowing your bottle range to remain relevant as feeding requirements change.

Expand the Product Line without Replacing the Bottle Platform

When the nipple flange and sealing structure remain compatible with your existing assembly, new baby nipples can be developed around the current bottle body and collar. You can add replacement and flow-specific products without developing another complete bottle, reducing the additional investment required to expand your product range.

Expand Your Bottle Range with Compatible Nipples

Share your bottle structure, nipple dimensions and planned flow stages. We can help you develop standalone silicone nipples that match your existing bottle range.

STRUCTURAL CUSTOMIZATION ADVANTAGE

Customize Silicone Baby Bottle Nipples for Existing Bottles

Combine an established bottle-side interface with different upper nipple structures.

Match the Nipple Base to Your Existing Assembly

The base of a new baby bottle nipple follows the flange and sealing profile of your original nipple. We match the relevant dimensions according to your sample or drawing, allowing the new nipple to maintain the required assembly relationship with your existing bottle neck and threaded collar.

same-interface-nipple-options-800x600.

Build Different Upper Forms on the Same Base

Once the lower interface is confirmed, the upper silicone structure can use a rounded nipple, flatter drinking spout or tubular straw connection. This gives you multiple baby bottle nipples with distinct appearances and feeding structures for the same bottle platform.

Concentrate Product Changes in the Silicone Nipple

The nipple direction, upper profile, wall structure and outlet configuration can be adjusted within the silicone nipple while the bottle neck and threaded collar retain their existing designs. This concentrates development on the component that creates the required product differences and keeps the current bottle-component system in use.

SAMPLE BASED CUSTOMIZATION

Develop Replacement Baby Bottle Nipples from Samples

Use one complete bottle sample to establish both the nipple design and assembly conditions.

Start from the Complete Original Bottle

You provide one complete original bottle sample at the beginning of the project, including the bottle body, threaded collar and nipple. We use the assembled product to identify the actual interface, nipple compression and installed position. This gives your replacement baby bottle nipple a development reference based on the complete product it must fit.

Correct Sample Deformation before Establishing Dimensions

We inspect the original nipple for flange compression, body stretching, silicone ageing and outlet wear before establishing the product dimensions. These conditions are compared with the assembled position inside the original bottle. This helps us restore a more reliable structure and reduces repeated sampling caused by transferring deformation from a used nipple into the new mold.

Convert Your Required Changes into Development Targets

You confirm the nipple profile, silicone hardness, straw connection and milk-opening structure required for the replacement product. We convert these requirements into measurable dimensions and material targets while retaining the confirmed bottle-side fit. This allows you to create clear functional or visual differences within your existing baby bottle nipple range.

Verify Every Prototype in the Original Assembly

We assemble every replacement nipple prototype with the original bottle and threaded collar to check flange compression, sealing contact, leakage and assembled flow. These are required validation steps before sample approval. You receive a prototype result evaluated as part of the complete bottle system, providing a dependable basis for tooling confirmation and mass production.

Develop Baby Bottle Nipples from Your Original Sample

Send us the complete bottle body, threaded collar and nipple together with your required changes. We will evaluate the original assembly and define the prototype development targets.

Parameter What You Confirm Effect on Your Product 
Silicone HardnessConfirm the target Shore A hardness or use the approved original nipple as the reference.Hardness affects nipple softness, deformation under suction and recovery after compression.
Tip and Sidewall ThicknessConfirm the required thickness distribution across the tip, sidewall and transition area.Two nipples using the same silicone hardness can produce different flexibility and recovery through different wall structures.
Upper Nipple ProfileSelect a rounded nipple, flatter drinking spout, straight outlet or another approved profile.The upper profile defines the feeding structure and creates visible product differences within your bottle range.
Milk-Opening StructureConfirm the opening type, size, position and quantity, including round holes, slits or cross-cuts.The milk opening is a primary factor affecting flow and must be confirmed through prototype and assembled testing.
Air-Vent DesignConfirm the vent position, slit form and opening response required for the nipple structure.The vent supports air replacement as milk leaves the bottle, affecting flow stability and leakage performance.
Straw ConnectionConfirm the straw diameter, insertion depth and connection structure for straw-compatible nipples.A defined connection keeps the straw positioned beneath the nipple and supports the intended liquid path.
FLOW COMPARISON AND APPROVAL

Verify Flow Differences before Finalizing Baby Bottle Nipples

Compare flow versions against an agreed reference before confirming your final product range.

Use Your Approved Nipple as the Flow Benchmark

You provide an approved nipple or define the expected direction for each flow version. We use this reference to establish the comparative target for new baby bottle nipples. This gives your team a concrete basis for reviewing samples and keeps development focused on the flow difference your product range actually requires.

Approve Flow Labels from the Comparison Results

Using the complete bottle sample already provided, we compare candidate nipples under the same agreed liquid, fill level, bottle position and test duration. The results show whether the output difference supports your intended product classification. You then approve the final version and corresponding flow label, while actual feeding performance remains influenced by liquid properties and use conditions.

NIPPLE PRODUCTION CONTROL

Production Control for Silicone Baby Bottle Nipples

Control molding cutting and version separation around your approved nipple design.

Silicone Nipple Fitted to the PP Assembly

Stabilize Thin-Wall Nipple Molding

Before the full production run, we stabilize the molding conditions around the approved nipple until the flange fills completely, the thin walls form correctly and the surface matches the sample. During production, flash, incomplete filling or visible deformation triggers process adjustment. This keeps your silicone baby bottle nipples within the confirmed molding result.

Maintain Fine Mold Cavities and Vent Paths

We keep the nipple cavities and fine vent paths clean during production because accumulated residue can affect the formation of thin tips and flange edges. Mold condition is reviewed when surface marks, incomplete filling or release changes appear. This helps your nipple retain the intended contour across the detailed areas of the mold.

Position Milk Openings with Dedicated Cutting Setups

Position Milk Openings with Dedicated Cutting Setups

Each milk-opening and air-vent design uses a dedicated positioning method and cutting setup. We locate the baby bottle nipple from its confirmed flange orientation, control the cutting depth and monitor tool condition during production. This keeps the opening in the intended position and supports the outlet structure approved during sample development.

Separate Different Flow Versions during Production

Separate Different Flow Versions during Production

When your order contains several flow versions, we separate their work instructions, cutting setups and handling containers throughout production. Each version remains identified until packing. This gives you better control over nipples that look similar externally but use different opening structures, reducing the risk of mixed flow versions in one delivery.

PACKAGING OPTIONS

Packaging Options for Your Baby Bottle Nipples

Choose packaging around your sales channel, product positioning and the number of nipples included in each retail or OEM pack.

24-printed-paperboard-hang-box-500x500

Printed Paperboard Hang Box

A printed hang box gives you enough space to present your brand, nipple flow, size, material and compatible bottle range. We can adjust the internal holder for one or multiple baby bottle nipples, helping you build clearly differentiated packaging for retail shelves and online product listings.

25-rpet-carded-blister-pack-500x500

rPET Carded Blister Pack

The clear rPET blister keeps the nipple visible while holding it in a defined position against the printed card. Different flow rates can use separate card colors and information layouts, allowing your distributors and retailers to distinguish silicone baby bottle nipples without opening the package.

26-bopp-cpp-retail-pouch-500x500

Printed BOPP/CPP Retail Pouch

A printed BOPP/CPP pouch combines a clear brand surface with a reliable heat-sealed closure. Its compact structure reduces packaging volume and leaves room for flow, age and compatibility information, giving you a practical retail option for e-commerce, regional distribution and price-sensitive product lines.

27-cpe-pe-inner-pouch-500x500

Heat-Sealed CPE or PE Inner Pouch

For OEM supply, replacement nipples or products packed inside an outer box, we can seal each nipple or set in a CPE or PE pouch. The separate inner pack limits direct handling during sorting and packing while helping you organize different flow rates before bulk delivery.

FAQs

Can one nipple flow be used for milk, water and thickened feeds?

No. The same opening produces different feeding results as liquid viscosity changes. Water passes through more easily, while thickened milk or cereal-based feeds may require a cross-cut, Y-cut or another suction-responsive opening. You should define the intended liquid before we determine the appropriate outlet behavior for your baby bottle nipples.

Can a soft silicone nipple also resist biting and tearing?

Yes. Softness and bite resistance are not complete opposites, but hardness alone cannot determine durability. Silicone tear strength, local wall thickness, structural transitions and repeated flexing all affect damage development. We therefore describe a baby biting nipple as bite-resistant rather than bite-proof and evaluate its structure under the intended use conditions.

Can a non-drip nipple and a free-flow nipple use the same outlet design?

No. A free-flow opening allows liquid to pass mainly under gravity, while a non-drip slit must remain closed until sufficient suction or pressure is applied. These products require different opening responses. Changing only the flow label cannot convert one behavior into the other, so the intended feeding action must be defined during development.

What causes a nipple to collapse during feeding?

Insufficient air replacement through the vent is the primary cause. When the vent remains closed, becomes blocked or opens too slowly, negative pressure builds inside the bottle and pulls the nipple inward. The threaded collar should remain securely tightened for sealing; collapse must be addressed through the vent structure rather than by loosening the collar.

Can every nipple outlet be formed directly in the mold?

No. Round holes and open spouts may be molded or punched depending on their structure, while precision slits, cross-cuts and Y-cuts are commonly created after molding. Post-molding cutting allows the opening to remain closed without suction and respond when pressure is applied. The forming method therefore depends on the required outlet behavior.

Can standard food-grade silicone nipples withstand repeated UV sterilization?

Not reliably. Standard boiling and steam cycles are commonly used for silicone baby bottle nipples, but repeated UV exposure may accelerate hardening, discoloration and crack development. If UV sterilizers are common in your target market, that condition should be evaluated separately and reflected accurately in your product care instructions rather than grouped with conventional heat sterilization.
