Product Overview
The Molded Plastic Gear is a one-piece injection-molded component for compact actuator and transmission assemblies. The current reference model has a 30 mm outer diameter, Module 1.0 tooth geometry, a 2 mm hub, and a D-shaped shaft hole. The teeth, hub, and shaft interface are formed in the same molding cycle.
Key Advantages
Transmission Features Formed in One Molding Cycle
The teeth, 2 mm hub, and D-shaped hole are molded from the same tool datums. This eliminates a separate hub-to-gear joining operation and keeps the shaft connection aligned with the tooth circle.
Tool-Based Repeatability for Ongoing Production
Once the mold and process window are approved, each cycle reproduces the same Module 1.0 tooth profile and 30 mm outer diameter. Process control helps maintain consistent fit in repeat production.
Positive D-Shaped Shaft Connection
The D-shaped hole engages a matching flat shaft to transfer torque without relying on friction alone. The interface also establishes the gear's angular position during assembly.

Customization Capabilities
The 30 mm outer diameter, Module 1.0 tooth form, 2 mm hub, and D-shaped hole describe the current reference model. Related dimensions, tooth geometry, hub structure, shaft interface, and resin can be adjusted after the mating gear and installation space are reviewed.
Color, part identification, and mold-cavity layout can be configured for the production project. Any change to the tooth geometry or shaft interface is confirmed through drawing review and molded sample approval before serial production.
Quality Control
Tool qualification confirms the approved part dimensions and a stable molding window before serial production. First-piece and in-process inspection then track the critical geometry that controls mating performance.
Final release includes visual screening and a fit or mesh check against the approved mating component. When multiple cavities feed the same production batch, results are recorded separately by cavity.
FAQ
Q: What is the minimum order quantity?
A: The standard MOQ is 10,000 pieces. The final commercial quantity also depends on resin, cavity count, cycle time, and annual demand.
Q: How is delivery scheduled?
A: Tooling status, material availability, order quantity, and the approved production plan determine the delivery schedule. Progress photos or videos can be supplied during production.
Q: Can a gear be reproduced from a physical sample?
A: Yes. The sample can be measured and converted into 2D and 3D data. The tooth standard, mating gear, tolerances, material, and duty cycle must still be confirmed before tooling.
Q: Can the mold be modified after the first trial?
A: Minor dimensions can be corrected when the tool includes steel-safe allowance or replaceable inserts. Major changes to module, tooth count, center distance, or part architecture normally require a new insert or mold revision.
