Frequently Asked Questions

Get answers to common questions about plastic gear manufacturing, materials, and applications.

What are the main advantages of plastic gears over metal gears?

Plastic gears offer significant advantages including 80% weight reduction, 60% noise reduction, corrosion resistance, self-lubrication properties, and 50-90% lower production costs. They’re ideal for applications where these characteristics are valued over maximum load capacity.

How do I choose the right plastic material for my gear application?

Material selection depends on operating temperature, load requirements, chemical exposure, and environmental conditions. Nylon offers excellent wear resistance, POM provides dimensional stability, and PEEK delivers superior high-temperature performance. Our engineering team can help you select the optimal material for your specific application.

What manufacturing process is best for my plastic gear requirements?

Injection molding is ideal for high-volume production (1000+ pieces) with consistent quality and lower per-part costs. CNC machining is better for prototypes, small batches (5-50 pieces), or complex geometries requiring tight tolerances. We can recommend the most cost-effective approach based on your quantity and specifications.

What tolerances can you achieve with plastic gears?

Injection molded gears typically achieve ±0.05mm tolerances, while CNC machined gears can reach ±0.005mm tolerances. Specific tolerances depend on gear size, material properties, and manufacturing method. We provide detailed tolerance capabilities during the quotation process.

How long is the typical lead time for custom plastic gears?

CNC machined prototypes: 5-10 business days. Injection molded parts: 2-4 weeks for tooling plus 1-2 weeks for production. Rush orders can be accommodated with expedited scheduling. Lead times vary based on complexity, quantity, and current production schedule.

Do plastic gears require special lubrication or maintenance?

Many plastic materials, particularly Nylon and POM, offer self-lubricating properties, eliminating the need for external lubrication in most applications. This reduces maintenance requirements and operational costs while preventing contamination in sensitive environments like food processing or medical equipment.

What quality certifications and testing do you provide?

We maintain ISO 9001:2015, AS9100D, and ISO 13485 certifications. Standard quality documentation includes dimensional inspection reports, material certifications, and performance test results. Additional testing such as torque testing, fatigue testing, and environmental testing can be provided upon request.

Can you help with gear design optimization?

Yes, our engineering team provides design optimization services including tooth profile analysis, material selection guidance, and manufacturing method recommendations. We use advanced CAD software and finite element analysis to optimize gear designs for performance, manufacturability, and cost-effectiveness.
