China Standard High Torque Gear Box of Double Screw Extruder with high quality

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.

Advantages of Plastic Gearboxes in Terms of Weight and Efficiency

Plastic gearboxes offer several significant advantages in terms of weight and efficiency, making them an attractive choice for various applications:

  • Lightweight Construction: Plastic gearboxes are inherently lighter than their metal counterparts. The use of lightweight materials reduces the overall weight of the machinery or equipment, leading to easier handling, reduced energy consumption, and improved portability.
  • Efficient Power Transmission: Plastic gearboxes are designed to ensure efficient power transmission with minimal energy losses. Their low friction characteristics and precise engineering contribute to higher efficiency, resulting in optimized performance and reduced energy consumption.
  • Reduced Inertia: The lightweight nature of plastic gearboxes leads to lower inertia, allowing for quicker acceleration, deceleration, and directional changes. This is particularly beneficial in applications requiring rapid and precise movements.
  • Low Lubrication Requirements: Plastic gearboxes often require less lubrication compared to metal gearboxes. This not only reduces maintenance efforts but also minimizes the risk of oil leakage or contamination in sensitive environments.
  • Noise Reduction: Plastic gearboxes’ inherent damping properties contribute to quieter operation. The reduction in noise levels enhances user comfort and minimizes sound pollution in various settings.

The combination of lightweight construction, efficient power transmission, reduced inertia, low lubrication requirements, and noise reduction makes plastic gearboxes an excellent choice for applications where weight savings, energy efficiency, and smooth operation are essential.

Types of Plastics Commonly Used in Manufacturing Plastic Gearboxes

Several types of plastics are commonly used in the manufacturing of plastic gearboxes, each offering specific properties and advantages:

  • Polyamide (Nylon): Nylon is a popular choice due to its excellent wear resistance, low friction, and good impact strength. It can handle moderate loads and is suitable for various applications.
  • Polyoxymethylene (Acetal): Acetal provides high stiffness, low friction, and good dimensional stability. It is often used for small gears and low-load applications.
  • Polyethylene (PE): PE offers low friction, good impact strength, and chemical resistance. It’s suitable for applications with light loads and low speeds.
  • Polycarbonate (PC): PC provides high impact resistance and transparency. It’s used in applications requiring good visibility and moderate load-bearing capacity.
  • Polyphenylene Sulfide (PPS): PPS offers high temperature resistance and chemical resistance. It’s suitable for applications in demanding environments.
  • Polyetheretherketone (PEEK): PEEK is a high-performance plastic with excellent temperature and chemical resistance. It’s used in high-temperature and harsh environments.

The choice of plastic depends on the specific requirements of the application,plastic gearbox

Ensuring Durability and Strength of Plastic Gearboxes

Manufacturers employ several strategies to ensure the durability and strength of plastic gearboxes:

  • Material Selection: Choosing the appropriate plastic material with the right mechanical properties for the specific application, considering factors like load, speed, temperature, and environment.
  • Engineering Design: Designing gear teeth profiles, dimensions, and housing structures that distribute loads evenly and minimize stress concentrations.
  • Reinforcement: Incorporating additives or reinforcements such as glass fibers, carbon fibers, or minerals to enhance the strength and rigidity of the plastic material.
  • Precision Manufacturing: Utilizing advanced manufacturing techniques, such as injection molding or precision machining, to produce accurate and consistent gear components.
  • Tolerances and Clearances: Ensuring proper tolerances and clearances between gear teeth to reduce friction and prevent premature wear.
  • Testing and Quality Control: Conducting rigorous testing, including load testing, wear testing, and environmental testing, to verify the gearbox’s performance and durability.

By combining these approaches, manufacturers can create plastic gearboxes that meet the required durability and strength standards for various applications.
