About Custom Nylon Gear
Sango Automation can support precision gear manufacturing of various materials, in addition to stainless steel gears, carbon steel gears and other metal gears, we are also able to manufacture some plastic material gears, common are custom PTFE + carbon fiber gears, custom nylon gears, etc., the gear accuracy level we can achieve is ISO/DIN/GB level 5.
Product Features
Custom tooth shape
Thanks to the injection molding process, our Custom Nylon Gear can achieve a wide range of tooth shapes, such as spur gears, helical gears, herringbone gears, helical bevel gears, and other non-standard tooth shapes.
Self-lubricating
Custom nylon gear has good self-lubrication, low friction coefficient, and low noise during operation without the need to add additional lubricant, which can replace metal gears in many scenarios.
Low cost
Injection molding or machining gears with nylon materials can achieve lower costs than using metal materials to produce gears.
Failure Mode and Effects Analysis
As a professional gear manufacturer, we at Sango proactively apply the FMEA methodology in the initial stages of gear design, systematically analyzing potential risks and formulating preventive measures.
Here's our analysis of three common failure modes for custom nylon gears and our solutions:
|
Failure Mode
|
Cause Analysis
|
Solution
|
|
Tooth Root Breakage
|
This failure mode is often caused by unexpected shock loads or insufficient toughness of the material, causing one or more teeth of the gear to break from the root, ultimately leading to complete drivetrain failure.
|
In the design stage, finite element analysis (FEA) software is used to simulate stress to optimize the root shape and avoid stress concentration. In the production stage, we will choose PA6 or toughened nylon with excellent impact resistance, and strictly control the production process to eliminate internal defects.
|
|
Excessive Surface Wear
|
This failure mode is due to the presence of contaminating particles in the transmission system, excessive loading, or insufficient wear resistance of the material. This leads to excessive wear of the gear surface material, resulting in increased clearance, reduced accuracy, and vibration.
|
In terms of material selection, we will choose reinforced nylon materials with glass fiber or molybdenum disulfide to improve the hardness and wear resistance of the gears.
|
|
Increased Noise & Vibration
|
This mode may result in significantly increased gear operating noise due to poor installation alignment, insufficient gear accuracy, or smaller side clearance after moisture absorption, accompanied by vibration, affecting the experience and equipment life.
|
Provide technical support to customers while providing humidity control to all precision nylon gears to stabilize the size and fundamentally avoid noise problems caused by moisture absorption and expansion.
|
Technical Parameter
The most commonly used nylon material at Sango Automation is PA 6, the molecular chain of PA6 is more flexible than PA66, has better toughness and ability to absorb shock loads, and it has a low coefficient of friction, which is a good self-lubricating material that can be well applied to custom nylon gears, the table shown below is some key performance data about this material.

FAQ's of Custom Nylon Gear:
Q: How are custom nylon gears produced by your company?
A: Our custom nylon gears are manufactured in India using high-quality plastic material, processed through advanced hobbing techniques. This method ensures accurate tooth profiles and maintains the integrity of the gears, resulting in efficient performance for industrial applications.
Q: What are the primary uses of these industrial nylon gears?
A: These gears are engineered for a wide array of industrial machinery, including conveyors, automation equipment, and mechanical drives. Their durability and resistance to abrasion make them suitable for continuous operation in demanding settings.
Q: When should I choose nylon gears over metal or other materials?
A: Nylon gears are ideal when you need lightweight, corrosion-resistant, and quieter gear solutions. They are especially useful in environments with moderate loads and where lubrication may be limited. Their cost-effectiveness and reduced wear on mating parts offer additional advantages over some metal alternatives.
Q: Where do you supply and export custom nylon gears?
