The company states that it operates over 190 injection molding machines, suggesting substantial production flexibility across different part sizes and volumes. Earlier local company information also reported a mix of machining and molding equipment, including wire-cut EDM, machining centers, and injection machines, which supports a tooling-and-production model rather than a pure molding-only operation.
Products and Technologies
Ningbo Gerui’s product portfolio is centered on precision transmission components and molded engineering plastic parts. The company emphasizes products intended for applications requiring tight tolerances, lower operating noise, and repeatable assembly performance.
Key product and technology areas include:
- Plastic gears such as straight gears, helical gears, worm gears, and planetary gears
- Gearbox assemblies and gear system components
- Two-shot molding for multi-material or multi-color parts
- Precision molds for functional plastic components
- Optical parts and other high-accuracy molded products
In technical terms, these products typically require careful control of mold precision, shrinkage behavior, tooth profile accuracy, and noise performance in transmission parts. The company’s emphasis on low-noise components is especially relevant for small motors, actuators, and compact drive units used in automotive and household products.
Its tooling and process capabilities are reinforced by references to CAD/CAM/CAE-based product development and in-house machining equipment in earlier company descriptions, indicating a vertically integrated approach to mold design and part production.
