China Standard China High Torque Twin Screw Pelletizing Extruder Gear Box cycloidal gearbox

Product Description

Polytek co-rotating twin-screw extruders are designed for maximum reliability, ease-of-use and flexibility. We offer turn-key solution for all types of material compounding applications.

we are proud to introduce our PTH series extruder which equiped with high torque and high speed gear box, desinged with specific torque of

12Nm/cm3 to achieve high screw filling rate, which results in a decrease of melt temperature, thus improving compound quality.

what is twin screw extruder 

Co-rotating twin-screw extruder : Due to the co-rotating twin-screw has the opposite speed at the meshing point, 1 screw pulls the material into the meshing gap, and the other screw pushes the material out of the gap, resulting in material from 1 screw turns to the other screw and advances in a “∞” shape. Since the gap of the meshing zone is small, the speed of the meshing screw and the groove are opposite in direction, so that the cutting speed is high, and the self-cleaning effect is good, that is, any accumulated material adhering to the screw can be scraped off, thereby The residence time of the material is very short, so the twin screw extruder is mainly used for compounding and pelletizing .

Polytek also have 2 stage extruder for PVC compound and high filler masterbatch extrusion.

Performance of Plastic Gearboxes in Automotive Applications

Plastic gearboxes have gained popularity in automotive applications due to their specific performance attributes and advantages. Here’s how plastic gearboxes perform in automotive settings:

  • Weight Reduction: Plastic gearboxes are lightweight compared to their metal counterparts, contributing to overall weight reduction in vehicles. This helps improve fuel efficiency and reduce emissions.
  • Noise and Vibration Dampening: Plastic gearboxes exhibit better noise and vibration dampening characteristics, leading to quieter and more comfortable driving experiences.
  • Corrosion Resistance: Plastic gearboxes are less susceptible to corrosion and rust, making them suitable for automotive components exposed to various environmental conditions.
  • Cost-Effectiveness: Plastic gearboxes can be more cost-effective to manufacture than metal gearboxes, contributing to cost savings in vehicle production.
  • Precision and Durability: Advanced engineering and material technologies ensure that plastic gearboxes offer the required precision and durability for automotive applications.
  • Specific Applications: Plastic gearboxes are used in automotive systems like windshield wipers, power windows, HVAC controls, and seat adjustment mechanisms.

Overall, plastic gearboxes in automotive applications contribute to improved vehicle performance, reduced weight, enhanced comfort, and cost-effective production.

Impact of Plastic Material Choice on Gearbox Performance

The choice of plastic material plays a crucial role in determining the performance of a gearbox, affecting factors such as durability, strength, friction, and operating conditions:

  • Strength and Durability: Different plastic materials offer varying levels of strength and durability. High-performance engineering plastics, such as reinforced nylon, acetal, and PEEK, can provide excellent mechanical properties, allowing the gearbox to withstand higher loads and torque.
  • Friction and Wear: The coefficient of friction and wear resistance of plastic materials influence the efficiency and lifespan of the gearbox. Proper material selection can minimize friction, reduce wear, and extend the operational life of the gearbox.
  • Temperature and Chemical Resistance: The operating environment’s temperature and exposure to chemicals can affect plastic material performance. Choosing materials with suitable temperature and chemical resistance ensures the gearbox’s reliability and longevity.
  • Noise and Vibration: Certain plastic materials have inherent noise and vibration damping properties, contributing to quieter and smoother gearbox operation. These materials are beneficial in applications where noise reduction is important.
  • Weight: The density of the plastic material affects the gearbox’s weight. Lighter materials can lead to overall weight reduction in the system, which is desirable for applications requiring portability or reduced inertia.
  • Cost and Manufacturing: The cost of plastic materials varies based on their properties and availability. Additionally, different plastic materials may require specific manufacturing processes or tooling considerations.

Therefore, the careful selection of plastic materials is essential to ensure the desired gearbox performance, longevity, and efficiency for a specific application.
