Frequently Asked Questions
Order & After-Sales
Q
Are the products compliant with industry standards for specific fields (e.g., automotive/medical)?
A
Absolutely. Our automotive-related products meet IATF 16949 requirements, and medical-use micro-transmission parts align with relevant medical device precision and safety standards—ensuring compliance with industry regulations.
Q
Can SANI adjust product parameters (e.g., torque, speed) based on my application feedback?
A
Yes. After receiving your feedback on sample or trial use, our engineering team can optimize parameters like torque, speed, or material to better match your application needs.
Q
What is the minimum order quantity (MOQ) for custom double helical gears?
A
We support flexible order quantities to accommodate both prototyping and mass production needs. Please contact our sales team with your specific requirements for a tailored quotation.
Q
What materials are available for custom helical gears, and how do I choose the right one?
A
We offer engineering plastics including POM (Crystal Steel) and PA66 (Nylon). POM is ideal for high-precision, low-noise applications, while PA66 offers superior wear resistance for heavier load scenarios. Our engineers can recommend the best option based on your operating conditions.
Q
What is the typical lead time for custom gear orders?
A
Lead times vary depending on order complexity and quantity. Sample production is typically completed within a short turnaround, while bulk orders are scheduled based on production capacity. Contact us with your project timeline for a precise delivery estimate.
Q
How does SANI ensure the quality and consistency of each gear produced?
A
All gears are manufactured using full Japanese equipment with strict process controls. Tooth profile accuracy is maintained within ±0.2mm, and every batch undergoes life testing exceeding 500,000 revolutions to verify durability and performance consistency before shipment.
