Product Overview
Small Plastic Gear Wheels are a miniature product range for micro-motor and compact actuator gear trains. The range extends beyond a single spur design and can include pinions, helical wheels, compound gears, and other small molded architectures used across several stages of one transmission.
Key Advantages
Multiple Miniature Gear Architectures
The range can include a motor pinion, an intermediate wheel, or a compact compound part. Several functions in a micro gearbox can be developed within one coordinated size envelope.
Low Rotating Mass in Fast-Response Drives
A small molded wheel adds little inertia to the train. Micro motors can start, stop, and reverse without carrying unnecessary rotating mass at each stage.
Assembly Features Within a Small Envelope
Where molding space permits, the hub, shaft interface, and retaining feature can be integrated into the gear. This reduces the need for separate spacers or adapters around closely positioned shafts.

Customization Capabilities
The range covers miniature pinions, spur gears, helical wheels, and compact compound parts for micro-motor gear trains. Geometry is developed around the complete diameter envelope, shaft spacing, and ratio sequence.
Small hubs, shaft interfaces, and retaining features can be added within molding limits. Material and cavity layout are selected to preserve the small tooth form across production.
Quality Control
First-piece inspection focuses on the bore-to-tooth relationship and the smallest functional features. In a miniature mesh, minor dimensional drift has a larger effect.
A low-torque running check verifies consistent rotation across the gear stage. Cavity results are kept separate so variation within a multi-cavity mold can be identified.
FAQ
Q: Which shipping terms are available?
A: EXW and FOB are available. Freight and export packing are quoted according to shipment volume and destination.
Q: Can samples be supplied?
A: Yes. Standard or custom samples can be supplied before production. Custom sample development normally takes about 50 days after drawing approval.
Q: Can a cavity number or trace code be added?
A: Yes, when the part has sufficient marking area. The code can be molded into the hub or added by laser marking without entering the tooth contact zone.
Q: How are small teeth protected during handling?
A: Compartment bags, formed trays, layer separators, or counted tubes can be used so the tooth tips do not carry the weight of adjacent parts during storage and transport.
