Electric toothbrush factory · Guangdong, China
OEM electric toothbrushes, built on our own micro motors
Jinsifang Technology makes sonic-sweep electric toothbrushes for private-label brands, pharmacy chains and corporate-gift programmes. We build the motor, the drive train and the finished product under one roof — so MOQ, tooling and unit cost are ours to move, not a supplier's to pass on.

Why this site is built the way it is
Five questions every buyer asks before placing a first order
Sourcing an electric toothbrush is not shopping. It is screening a supplier. So this site is structured as five gates — each one answers a question you are already holding when you land here.
01
Are you the factory, or a trading company?
A registered Shenzhen entity with its own plant in Dongguan, its own tooling and its own test benches — every machine shown on this site is ours.
The question you are holdingAbout us
02
Can you build something other than the standard mould?
We design and wind our own micro motors, so handle geometry, drive train, mode logic and intensity curve are all things we can change — not things we have to ask someone else for.
The question you are holdingOEM / ODM capability
03
Will the paperwork survive my customs and my QA?
Certificates, test reports, HS codes, carton data and MOQ tiers are laid out in full, with the documents we actually hold published as scanned copies you can verify.
The question you are holdingCertifications & compliance
04
Do you understand the channel I sell into?
Corporate-gift runs of a few hundred pieces and private-label programmes of tens of thousands are different products with different packaging. We quote them differently.
The question you are holdingCorporate gifting
05
Will container three match the sample I approved?
Ten QC gates per batch — charging ageing, noise, motor ageing, insertion-life, waterproofing, finished-goods ageing — each logged on a bench, with photographs you can audit.
The question you are holdingQuality control
Product range
What we manufacture
One core product, engineered deeply — plus the consumables that make it a recurring revenue line for your brand.
Consumable
Replacement brush heads
Registered under trademark class 21. Soft and medium filament, round or diamond profile, blister, box or bulk — the recurring order behind every handle you sell.
Second line
High-speed hair dryer
Second personal-care line from the same motor platform: brushless high-speed motor, negative-ion outlet, constant-temperature control, two concentrator nozzles.
Original business
Micro motors & precision components
The business we started with: micro motors and lock hardware for smart-home, security and consumer-electronics customers.
Programmes
Built for how you sell
The same handle becomes a different product depending on the box it arrives in.
Corporate gift run — from 50 pieces
A finished, wrapped gift set with your company mark. Short runs, fast turnaround, used for annual events, client appreciation and staff benefits.
Brand collaboration — from 500 pieces
A retail-grade gift box with your logo on the handle as well as the sleeve, built for co-branded launches, bank reward programmes and loyalty catalogues.
The decision buyers usually get wrong
Gift buyers tend to over-specify the electronics and under-specify the box. In the corporate channel, the unboxing sequence sets perceived value far more than an extra brushing mode does — and it costs less to change.
Manufacturing
Tested on our benches, not on your customers
Every unit passes through charging ageing and function test. Every batch is sampled for noise, insertion life and waterproofing. Here is the equipment, photographed as it runs.
In-process
Assembly line control
Handles are assembled and charged on a single line. Each operator works one station, and work-in-progress is photographed at the end of every shift.
100 % of units
Charging & ageing
Every finished handle goes onto the charging-ageing racks, so a cell or charging fault shows up here rather than in a customer's bathroom.
Batch sample
Noise test room
A sound-insulated room, tested against a ≤45 dB ambient baseline. The sample is measured at 10 cm on the main axis; the criterion is an even, harmonic sound with no abnormal or intermittent noise.
200 h
Motor ageing bench
Continuous running for 200 hours minimum, through warm-up and cool-down cycles, with temperature and humidity logged and stable current and voltage recorded at fixed intervals.
5,000 / 10,000 cycles
Insertion & switch life
Switch actuation tested to 10,000 cycles, brush-head and Type-C plug tested to 5,000 cycles, all at 1.0–2.0 kgf. The product must remain fully functional and the click-feel unchanged.
100 % of motors
Stator comprehensive test
Electrical strength, insulation, inter-turn short circuit, resistance, inductance and electrical balance are measured on every stator before it enters assembly.

What we have learned answering buyer questions about certifications, cost structure, drive systems and shipping paperwork.
Sourcing & vetting
Private-label electric toothbrush: who owns what, from artwork to first container
Most private-label failures are not manufacturing problems. They are things nobody owned: a trademark, a WEEE number, a label field. Here is where the lines run.
Sourcing & vetting
How to evaluate an electric toothbrush manufacturer: ten checks in 30 minutes
Most sourcing disasters in this category are not bad products. They are a buyer spending three weeks negotiating with a company that could never have made the product. Ten checks, one document each.
Cost & MOQ
How MOQ is actually set: the cost structure behind the quantity tiers
Why the per-unit price falls as quantity rises, which costs are genuinely one-off, and how to size a first order so the third one is cheaper.

One product, engineered deeply — then shaped around your brand
Jinsifang is a contract manufacturer. Our own mark competes with nobody: the toothbrush programme exists to carry other people's brands.
