02 · Dimensional Fit
Engineered to Match Your Bottle System.
Every accessory is reverse-engineered from your existing bottles -- or developed in parallel with new bottle designs -- ensuring perfect threading, sealing, and user experience.
Neck Diameter Mapping
Compatible with standard (Ø34), wide-neck (Ø42-50), and custom neck threads.
3D Scanning & CAD
Full digital modeling to replicate or improve existing accessory geometries.
Tolerance ±0.1mm
Precision molding ensures no leakage, slippage, or awkward fit after assembly.
Age-Stage Sizing
Flow rates and spout softness tailored for 0-6M, 6-12M, 12M+ developmental stages.
03 · Sealing Engineering
Zero-Leak Sealing & Secure Connections.
Our structural engineers design multi-layer sealing systems proven under pressure, temperature, and real-world drop conditions.
Primary O-Ring Seal
Compression-optimized profile for 100% leak-proof pressure sealing.
Dual-Layer Flange
Secondary flange structure prevents micro-leakage under tilt or shake.
Anti-Colic Valve
Integrated venting valves reduce air intake during feeding.
Snap-Fit Lock
Audible click-lock mechanisms for secure, child-safe assembly.
Tested beyond standards.
Each sealing design passes 1,000+ open/close cycles, 1.2m drop tests, and leak-proof simulation under −20°C to 120°C.
04 · Protective Design
Safer Grip. Softer Impact.
Silicone's natural tactility is amplified through engineered textures and strategic shock-absorbing structures -- protecting both the bottle and little hands.
Textured Grip
Dot, ribbed, or diamond-pattern anti-slip surfaces.
Drop Protection
Full-sleeve covers absorb impact from 1.5m falls.
Soft-Edge Finish
Rounded, deburred edges for safe tiny fingers.
Hypoallergenic
Soft-touch Shore A hardness tuned for comfort.
+45%
Grip tensile improvement vs standard silicone.
05 · Color & Branding
Your Palette. Perfectly Rendered.
Pantone-accurate color matching, custom logo imprinting, and finish options that let your brand identity shine through every accessory.
✦ Pantone Color Matching
Precision pigment formulation matched to your exact Pantone or RAL reference.
✦ Logo & Branding
Debossed, embossed, laser, silkscreen, pad printing, and UV-finish options.
✦ Surface Finishes
Matte, glossy, soft-touch, pearlescent, and translucent silicone finishes.
✦ Colorfast & Food-Safe
All pigments FDA / LFGB compliant, resistant to fading and sterilization cycles.
06 · Hybrid Engineering
Multi-Material. Overmolded. Assembled.
We go beyond silicone -- combining PP, PPSU, Tritan, stainless steel, and more into complete bottle accessory solutions.
Silicone + PP / PPSU
Overmolded sippy spouts, straw tops, and bottle caps combining durability with softness.
Silicone + Stainless Steel
Weighted straw assemblies and insulated spouts for thermal bottle systems.
Silicone + Tritan
Transparent, impact-resistant hybrid accessories for premium bottle lines.
Dual-Shot Molding
Single-cycle two-material injection for seamless bonding and aesthetic finish.
Manual Precision Assembly
Trained technicians handle delicate multi-component assembly with torque control.
Full Set Packaging
Pre-assembled retail-ready sets: box, instruction, blister, custom gift packaging.
