• Chamfers and radii

• Other structural details

With no intermediaries involved, we offer quick quotations, flexible production schedules, and competitive pricing to support a wide range of global sourcing needs.

Material Advantages for Electric Toothbrush Components

303 stainless steel offers several advantages for precision parts used in electric toothbrush assemblies:

• More cost-effective than 304 or 316 stainless steel, making it suitable for high-volume cost control.

• Excellent machinability, ideal for small and precise components.

• Compatible with protective surface treatments for improved durability in humid environments.

• Stable mechanical strength with low risk of deformation, ensuring long-term precision in transmission and fixing parts.

• Safe material with no harmful substances, meeting general safety requirements for consumer appliance components.

Precision Manufacturing for Electric Toothbrush Components

Custom Machining Designed for Toothbrush Assemblies

For parts such as brush head shafts, drive cores, and fixing sleeves, we use one-piece precision machining to eliminate joints and ensure a clean, integrated structure. This helps maintain tight assembly fit and reduces jamming or loosening during operation.

Micron-Level Precision Control

• Dimensional tolerance controlled within ±0.02 mm

• Hole and shaft accuracy within ≤0.01 mm

• Chamfer and step position accuracy within ≤0.03 mm

These tolerances ensure precise fit with other toothbrush components and support smooth overall product performance.

Surface Treatment Options

Available surface treatments include:

• Passivation

• Zinc plating

• Nickel alloy plating

• Chrome plating

These treatments improve wear resistance and light corrosion resistance, while keeping the surface smooth and burr-free for oral-care applications.

Full Inspection Process

Every production stage is carefully controlled:

• Material composition verification

• CMM dimensional inspection

• Surface finish inspection

• Geometric tolerance inspection

• Assembly fit testing based on actual electric toothbrush structures

Strict inspection at every step ensures stable quality and reliable performance.

Order Support

We support both neutral packaging and custom branded packaging. Packaging includes internal anti-scratch protection and cushioning to prevent impact damage during transportation, in compliance with international shipping standards.

Lead times are flexible and well controlled:

• 7–10 days for small batches

• 15–30 days for mass production

This makes our service well suited to global procurement needs for multi-variety, small-batch turned parts steel orders.

Core Performance

Dimensional Accuracy

• Diameter / hole tolerance: ±0.02 mm

• Length tolerance: ±0.03 mm

• Wall thickness tolerance: ±0.01 mm

These tolerances are designed to fit the compact internal space of electric toothbrush assemblies.

Geometric Accuracy

• Concentricity: ≤0.01 mm

• Roundness: ≤0.005 mm

• Perpendicularity: ≤0.03 mm

This ensures stable rotation without wobble or excess noise.

Performance in Use

After proper surface treatment, the parts offer improved wear resistance and resistance to everyday moisture, making them suitable for the humid conditions typical of electric toothbrush use. This helps prevent corrosion and wear from affecting overall product life.

Service Life

Under normal operating conditions, surface-treated 303 stainless steel parts can maintain stable performance for more than 5 years, with low risk of deformation, corrosion, or wear.

Design Flexibility

We can customize special shapes, precision holes, and dedicated thread interfaces according to product design requirements, ensuring compatibility across different brands and models of electric toothbrushes.
