Bost Custom Plastic Spur Gears — Precision Plastics
Custom Plastic Spur Gears by Bost — Precision, Durability, Performance
Advanced Materials & Tailored Properties
Bost leverages decades of engineering plastics expertise to deliver custom plastic spur gears engineered for your application. Using specialty grades—anti-scar, ultra abrasion-resistant, high-temperature transparent and conductive-modified plastics—we tune friction, wear resistance, impact toughness and thermal behavior to achieve optimal gear life and quiet operation.
Design, Mold Making & Precision Manufacturing
From concept to production, Bost’s R&D and mold design teams provide end-to-end services: CAD-driven tooth profiles, prototype runs, mold fabrication and precision injection or machining of gears from rods, sheets and molded blanks. Our combined steel-plastic and plastic-rubber experience ensures reliable gear geometry, tight tolerances and consistent assembly fit.
Performance Benefits of Custom Plastic Spur Gears
Choosing custom plastic spur gears from Bost yields multiple advantages: reduced noise, corrosion immunity, lower weight, self-lubricating options, and improved fatigue life in cyclic loads. Materials with enhanced flame retardance, conductivity or thermal dissipation are available for specialized industries such as automotive, medical devices, robotics and power equipment.
Sustainability & Quality Assurance
Bost is committed to green energy principles and high-tech manufacturing. Our quality systems and material selection minimize waste, support recyclability where possible, and ensure each gear meets mechanical testing and dimensional inspection standards. We offer traceability, material certificates and performance validation for critical components.
Customization, Lead Times & Support
Whether you need one prototype or high-volume production, Bost accelerates time-to-market with rapid tooling options and scalable processes. Our engineering team collaborates on optimization for cost, life expectancy and manufacturability. Contact Bost to specify module, pressure angle, face width and material to get a tailored quote for custom plastic spur gears.

How do I select the appropriate engineering plastic grade for my product?
Selection should be based on parameters such as load conditions (e.g., pressure/friction), temperature range, medium contact (e.g., oil/acid), and regulatory requirements (e.g., FDA/RoHS). Our engineers can provide free material selection consulting and sample testing.
What are the core advantages of Bost engineering plastics compared to ordinary plastics?
Bost engineering plastics feature ultra-high mechanical strength, high-temperature resistance (-50°C to 300°C), chemical corrosion resistance, and wear resistance. Compared to ordinary plastics, their service life is extended by 3 to 8 times, making them suitable for replacing metals in harsh environments.
What is the minimum order quantity (MOQ)? Do you support small-batch trial production?
The MOQ for standard products is ≥100kg. We support small-batch trial production (as low as 20kg) and provide mold testing reports and performance data feedback.
Can Bost customize modified plastics with special properties?
Yes! We offer modification services such as reinforcement, flame retardancy, conductivity, wear resistance, and UV resistance, for example:
• Adding carbon fiber to enhance stiffness
• Reducing the coefficient of friction through PTFE modification
• Customizing food-grade or medical-grade certified materials
What is the delivery lead time? Do you offer global logistics?
Standard products: 5–15 working days; custom modifications: 2–4 weeks. We support global air/sea freight and provide export customs clearance documents (including REACH/UL certifications).
