Plastic Spur Gear
Brand: Hansheng
Accuracy grade: ISO/DIN/GB level 7 – 11
Gear module: 0.4–5.0
Tip diameter: 3 mm–300 mm
Introduction
Plastic spur gear are widely used in precision transmission systems where low noise, lightweight structure, and corrosion resistance are required. Compared to metal gears, a Plastic Spur Gear offers excellent self-lubrication, cost efficiency, and stable performance in medium- and light-load applications.
At Hansheng Automation, we specialize in manufacturing custom plastic spur gear with over 10 years of experience in precision gear production. Our engineering team supports a wide range of gear types, including spur gears, helical gears, bevel gears, gear racks, and gear shafts.
We integrate advanced gear manufacturing processes such as gear skiving, gear hobbing, gear shaping, and gear broaching, ensuring optimal production solutions based on your application requirements.

Key Features & Advantages
Our plastic spur gears can achieve up to ISO/DIN Level 7 accuracy.
Due to the inherent damping properties of plastic materials, a Plastic Spur Gear operates significantly quieter than metal gears.
Ideal for applications where weight reduction and chemical resistance are critical.
Injection molding enables large-scale production of custom plastic spur gears with consistent quality and reduced unit cost.
We select the optimal process—gear skiving, hobbing, shaping, or broaching—based on gear structure and volume.
Customization Options
- Module & number of teeth
- Inner bore design (keyway, spline, custom)
- Tooth modification (profile shifting, crowning)
- Material selection
- Surface finishing
- Color & branding
We support both low-volume prototyping and mass production.
Material Selection for Plastic Gears
Choosing the right material is critical for the performance of a Plastic Spur Gear.
Common Materials:
- POM (Acetal)
- Nylon (PA6 / PA66)
- ABS
- PEEK
Material Selection Recommendations:
- High precision & low friction → POM
- Impact resistance → Nylon
- High temperature → PEEK
- Cost-sensitive projects → ABS
Our engineers can recommend the optimal material for your plastic spur gear application.
Manufacturing Capability
At Hansheng Automation, we understand that precision in plastic gears isn’t just about the machine—it’s about managing material behavior. We provide high-stability machining for engineering plastics (POM, Nylon, PEEK, Delrin).
Gear Skiving & Hobbing (Machined Precision)
Accuracy: GB Level 7–9 (Professional Grade)
Expertise: By using high-rigidity CNC equipment (Kashifuji/Ningjiang), we minimize the “spring-back” effect of polymers, achieving the upper limits of plastic gear precision.
Ideal for: Medical devices, precision instruments, and low-backlash encoders.
Gear Shaping (Internal & External)
Accuracy: GB Level 8–10
Advantage: High-speed shaping with controlled stroke speeds to prevent thermal build-up, ensuring dimensional stability of complex internal tooth profiles.
