Home appliances increasingly rely on plastic gears for quieter efficient operation, particularly in small kitchen devices and other small household appliances. The kitchen blender market is growing at 6% CAGR, and autonomous vacuum cleaners at 15% CAGR. Compact gears need durable materials to withstand high loads and temperatures. Stanyl® PA46 enables manufacturers to create compact, strong, and reliable components, enhancing both design and performance.
Stanyl® PA46: A proven solution for enhanced gear performance
Stanyl® PA46, a high-performance polyamide from Envalior helps address performance related issues that are sometimes occurring in compact gears used in demanding consumer goods applications. With superior temperature performance, high fatigue strength and low friction and low wear, Stanyl® PA46 outperforms many other engineering plastics used in gears, such as POM (acetal), PA66, and PPA, delivering up to 50% more gear life performance.
Key Benefits of Stanyl® PA46 for Gear Applications:
- High torque and high load capacity: Able to cope with high mechanical loads, delivering consistent and reliable performance for applications that require frequent or intense use.
- Low wear and low friction: Over a broader range of operating temperature, load and sliding speed, in both dry and in grease / oil lubricated conditions.
- Enhanced processing efficiency: Combines high flow and high crystallization rate with a high crystallinity level, enabling low wall thickness, low cycle time, yet strong and durable injection molded parts.
- Material savings: Compared to many other polymers, Stanyl® PA46 enables gear manufacturers to use up to 30% less material without compromising part performance while enabling short cycle times and thus quicker and more cost-effective injection molding.
For gears used in demanding applications, Stanyl® PA46 exhibits unmatched durability properties and performs reliably under conditions where alternative materials often face a challenge. This helps manufacturers create more compact, yet strong and durable gears components and thus devices that improve the user experience through both a more appealing design and also through reliability and performance.
Pictured above, Stanyl PA46 enables gear manufacturers to mold 7 mm plastic gears, using 30% less material than 10 mm gears made from competing PPAs—without losing any strength or durability.
Application development support
Envalior not only provides high-performance materials but also offers state-of-the-art application development support to help manufacturers optimize their gear designs. Our advanced design and CAE support services allow us to simulate real-life conditions by assessing how loads, friction, temperatures, and speeds impact the long-term geartrain performance. This enables manufacturers to fine-tune their designs and select the most suitable Stanyl® grade for their application, reducing the number of design iterations needed to achieve functional parts.
Our extensive portfolio of Stanyl grades combined with our application development support including design, CAE and material related support helps our customers during their development stages, ensuring that strength and durability performance needs are met in a cost-effective and sustainable way.
