Case Study: Level Detection Solution for PA66 Nylon Pellets in High-Temperature Environments

Background

In the field of polymer material processing, PA66 nylon pellets are widely used in the production of automotive components, household appliance casings, electronic parts, and other products. PA66 nylon offers excellent mechanical properties and heat resistance, making it a critical raw material for many high-temperature injection molding and extrusion processes. However, with the increasing automation of production, ensuring a reliable monitoring system for the PA66 nylon pellet levels in raw material storage becomes key to maintaining continuous production and improving operational efficiency.

Difficulties

During the processing of PA66 nylon pellets, they generally require pre-drying, and the processing temperature typically ranges between 280°C to 300°C, with some special cases requiring temperatures as high as 350°C, but rarely exceeding this range. In such high-temperature conditions, the level detection equipment must be capable of withstanding extreme temperatures while also handling the high-frequency vibrations and potential material buildup common in injection molding and extrusion processes. Additionally, PA66 pellets have a certain degree of adhesiveness, and traditional level switches often suffer from unreliable performance or false alarms due to material adhesion.

Solution

To address these challenges, an automotive parts manufacturer selected Jiwei Tuning Fork Level Switches as the core solution for PA66 nylon pellet level detection. These level switches offer several significant advantages that make them ideal for high-temperature level monitoring:

1. High Temperature Resistance
   Jiwei Tuning Fork Level Switches can withstand temperatures up to 400°C, fully accommodating the common processing environment of PA66 nylon pellets, which typically operates between 280°C to 300°C during injection molding and extrusion. Even in extreme conditions, the equipment remains stable, ensuring precise level monitoring.
2. Anti-Adhesion Design
   Designed to address the adhesive properties of PA66 nylon pellets, Jiwei Tuning Fork Level Switches feature a smooth surface that effectively prevents pellets from sticking. Even with prolonged use, the device maintains consistent performance, avoiding malfunctions or false alarms caused by material build-up.
3. Anti-Interference Performance
   In environments with high-frequency vibrations, Jiwei Tuning Fork Level Switches demonstrate outstanding anti-interference capabilities. Even under the intense vibrations of injection molding machines, the level switches operate stably, ensuring that detection data remains unaffected by external disturbances and preventing false alarms or misoperation.
4. High Reliability
   The switches are made from robust 316L stainless steel, offering excellent corrosion and wear resistance, making them highly durable in harsh industrial environments. Their design ensures long-term stability in high-temperature, high-vibration, and complex material conditions, thereby reducing maintenance and troubleshooting costs.

Application Effectiveness

By implementing Jiwei Tuning Fork Level Switches, the customer successfully achieved accurate level detection for PA66 nylon pellets, preventing production interruptions caused by low levels and ensuring continuous and stable operations on the production line. The switch’s stability and strong anti-interference capability significantly enhanced the plant’s operational efficiency, reducing downtime and maintenance costs associated with false alarms.

Additionally, the anti-adhesion design and high-temperature resistance of the Jiwei Tuning Fork Level Switch effectively resolved issues related to material adhesion and performance degradation in high-temperature environments, allowing the plant to run efficiently in complex production conditions.

Conclusion

In the high-temperature processing of PA66 nylon pellets, Jiwei Tuning Fork Level Switches, with their exceptional heat resistance, anti-interference capabilities, and anti-adhesion design, have successfully addressed challenges that traditional level switches could not handle. They have helped improve automation levels and overall reliability in the production line, ensuring precision and stability in level monitoring within the polymer material processing industry.
