Empowering global oral care brands with strict time-to-market constraints. We design, manufacture, and supply sonic toothbrushes with full IPX7 validation, custom retail packaging, and uncompromising batch stability.
In-house assembly lines and rigorous PCB testing ensuring consistent quality control.
Dedicated structural and electronic engineers for custom motor tuning and innovation.
Flexible MOQs, precise Pantone matching, and premium blister packaging solutions.
Explore our main product categories engineered for private label, wholesale, and customized oral care projects. We handle everything from handle molding to final packaging assembly.
Sonic models delivering 31,000-38,000 strokes/min. Features include built-in 2-minute timers, magnetic levitation motors, and fully sealed IPX7 waterproof structures for shower safety.
Compact handles adapted for smaller grips. We utilize food-grade silicone wraps and ultra-soft DuPont bristles, mitigating brushing resistance in pediatric daily routines.
High-density tufting processes for whitening, sensitive, and gum care variants. Shaft interfaces can be customized to ensure precise compatibility with your existing handle designs.
Wall-mounted and travel disinfection boxes integrating UVC-LED modules. Addresses consumer concerns regarding bathroom hygiene and bristle bacteria accumulation.
Cordless, rechargeable oral irrigators featuring pulse technology and detachable water tanks. Engineered for leak-proof performance during transit and daily use.
Complete your product ecosystem with custom-molded travel cases, inductive charging bases, hygienic brush head covers, and wall-mount holders.
Choose from pre-engineered platforms for entry-level, premium, kids, and travel markets. Utilizing established structural designs reduces your tooling costs and accelerates sample approval.
For retail brands requiring robust daily performance, this series solves motor degradation issues via our proprietary magnetic levitation shaft. It sustains 31,000–38,000 strokes/min even under brushing pressure.
Targeting frequent travelers and premium segments where charging frequency is a constraint. We integrated a high-density 1200mAh battery paired with low-power consumption PCBA layout, achieving up to 450 minutes of endurance per charge.
Designed to solve the challenge of children's brushing compliance. The handle ergonomics are scaled down, and the motor frequency is calibrated to be gentle on developing gums, preventing enamel abrasion.
An ideal solution for wholesale distributors targeting entry-level price points or convenience store channels. Eliminates the need for charging infrastructure, utilizing standard AA batteries while maintaining core sonic vibration.
From initial 3D structural design to final mass production assembly, we provide end-to-end manufacturing support for global brands, ensuring your product specifications align perfectly with your market positioning.
Apply your brand identity via silk-screen printing, laser engraving, or hot stamping on the toothbrush handle, travel case, and retail packaging boxes.
Submit your target Pantone codes. We manage the plastic injection molding process to ensure exact handle and brush head color matching with strict MOQ compliance.
We provide die-cut templates for retail color boxes, premium gift boxes with EVA trays, and e-commerce optimized bundle packaging to reduce shipping volume.
Modify PCBA programming to customize LED indicators, alter cleaning mode sequences, adjust timer intervals, or upgrade battery capacities for specific markets.
Select from W-shape, 3D curved, or flat bristle topography. We source DuPont or Pedex filaments, supporting copper-free tufting technology upon request.
Bring your ID drawings. Our structural engineers will evaluate mold feasibility, internal component layout, and interface compatibility to move from concept to working prototype.
We eliminate the middleman markup and communication delays by integrating R&D, structural tooling, and final assembly under one roof in Ningbo.
Established in 2019, we don't dilute our expertise across unrelated electronics. We focus strictly on the R&D, tooling, and assembly of electric toothbrushes and personal care devices.
Our in-house electronic and structural engineers troubleshoot mounting holes, battery constraints, and waterproof sealing before mold injection begins.
We utilize dedicated fixtures for high voltage testing, battery lifecycle simulation, and swing frequency calibration to ensure mass production stability.
Avoid rigid supplier constraints. We support custom product combinations, varying brush head counts per set, and localized charging cables (US/EU/UK plugs).
Source your entire oral care catalog from one factory. Our lines cover adult sonic, kids models, battery-operated units, and UV disinfection boxes.
Guided by "Innovation Leads the Future, Quality Builds Brilliance," we build QC checkpoints directly into the assembly line, rejecting defective PCBA boards before casing.
B2B procurement requires tangible proof of capability, not just promises. From raw component intake to final packaging, we deploy specialized testing equipment to validate battery safety, waterproof integrity, and motor longevity, drastically reducing your RMA rates.
We adapt our packaging formats, MOQ thresholds, and certification support to match the specific procurement constraints of different sales channels.
Deep OEM customization including bespoke mold development, custom sonic frequency tuning, and premium gift box structural design to match brand equity.
Explore SolutionReady-to-sell SKU setups with blister packaging optimized for shelf space. We ensure barcode integration and multi-language manual printing.
Explore SolutionHigh-volume bulk supply focusing on cost-efficiency. Flexible master carton configurations to maximize container loading and reduce freight costs.
Explore SolutionE-commerce optimized drop-test passed packaging. We bundle multiple replacement heads and travel cases to increase your listing's perceived value.
Explore SolutionCompliance-focused manufacturing using non-toxic materials. Integration of gamified brushing timers and visually engaging water-transfer handle prints.
