01 · Product Range
Accessory Types We Manufacture.
We produce the full range of soft-touch silicone components found in modern nursing and feeding systems -- engineered for safety, suction integrity, and long-cycle durability.
Duckbill Valves
One-way flow control for breast pumps and bottle anti-colic systems.
Flange Inserts & Cushions
Soft-contact flanges in multiple sizes (17-27mm) for comfort fitting.
Diaphragms & Membranes
Thin-wall backflow protection and pressure regulation membranes.
Bottle Nipples & Teats
Multiple flow rates, slow/medium/fast, with natural latch-shape options.
Sealing Rings & Gaskets
O-rings and custom profile gaskets for airtight and leak-proof assembly.

02 · Dimensions & Compatibility
Engineered to Match Your System.
Every nursing accessory must mate perfectly with your existing hardware -- pump housings, bottle threads, and collection cups. We reverse-engineer or build from your CAD files to guarantee a flawless fit.
Flange Diameter Sizing
Standard sizes 17/19/21/24/27mm, plus custom profiles.
Thread & Mounting Compatibility
Compatible with wide-neck, standard-neck, and proprietary interfaces.
Flow Rate Calibration
Precise orifice sizing for slow, medium, fast, and variable flow.
03 · Material Selection
Material & Hardness Options.
100% food-grade platinum-cured silicone. Choose between LSR for complex geometries or HCR for high-volume parts, with precise Shore A hardness tuning.
Ultra-Soft
Flange cushions, skin-contact surfaces
Soft
Nipples, teats, pacifier bodies
Medium
Valves, membranes, diaphragms
Firm
Sealing rings, structural gaskets
FDA · LFGB · BPA-Free
Full certification support
LSR Injection Molding
32 liquid silicone machines
HCR Compression Molding

04 · Structural Design
Sealing, Connection & Protection.
Nursing accessories live or die by their seal integrity. We co-design structural features that deliver airtight performance under repeated sterilization cycles.
Lip Seals & O-Rings
Dual-lip and radial-compression designs that stay airtight across thousands of pump cycles.
Snap-Fit Connections
Tactile, audible snap engagement for assembly reliability -- no tools required for parents.
Anti-Backflow Barriers
Hygienic membranes that prevent milk flow back into tubing and motor units.
05 · Advanced Assembly
Multi-Material Components.
Beyond pure silicone, we specialize in overmolding silicone onto plastic (PP, PCTG, Tritan) or stainless steel -- enabling rigid-flexible hybrid parts that eliminate assembly steps and improve reliability.
Silicone + Plastic Overmolding
Soft grip on rigid structure, chemical-bonded interface.
Silicone + Stainless Steel Inserts
Durable threaded cores and reinforcement structures.
Dual / Tri-Material Molding
Different silicone hardnesses in one integrated part.
Sub-Assembly Services
Ultrasonic welding, pad printing, laser marking in-house.

06 · Sample Validation
Fit, Function & Sample Approval.
Before any mass production run, every custom part passes through a rigorous validation workflow -- ensuring your accessory performs exactly as designed in real-world usage.
3D-Printed Prototype
SLA/SLS rapid prototypes for first-look review within 3-5 days.
Soft Tooling Sample
Pilot aluminum molds producing material-accurate first samples.
Compatibility Testing
Full-system fit testing with your pump, bottle, or feeding assembly.
PPAP Approval
Signed sample approval before production tooling release.
