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.

Construction :
The Applications of Co-rotating Twin Screw Extruder
1.Glass fiber reinforced, fuel barrier palletizing (For example PA6, PA66, PET, PBT, PP, and PC reinforced flame retardant)
2.Highly filled material granulation (For example PE, PP filled with 75%CaCo)
3.Granulation of heat-sensitive materials (For example PVC, XLPE cable material)
4.Intense color masterbatch (For example filled with 50% color powder)
5.Antistatic masterbatches, alloys, coloring, low-fill co-mingling granulation
6.Cable material granulation (For example sheathing material and insulation material)
7.XLPE pipe material granulation (For example masterbatches for hot water crosslinking)
8.Thermoset plastic compounding and extrusion (For example phenolic resin, epoxy resin, and powder coating)
9.Hot melt adhesive, PU reactive extrusion palletizing (For example EVA hot melt adhesive and polyurethane)
10.K resin, SBS de-volatile granulation

How to Choose the Right Gearbox for Your Machinery
Selecting the appropriate gearbox for your machinery involves careful consideration of several key factors. Here’s a step-by-step guide to help you make the right choice:
- Identify Application Requirements: Understand the specific requirements of your machinery, including torque, speed, load, direction of rotation, and duty cycle.
- Choose Gear Type: Determine the type of gears that best suit your needs, such as spur, helical, bevel, planetary, or others, based on factors like efficiency, noise level, and space constraints.
- Calculate Gear Ratio: Calculate the required gear ratio to achieve the desired output speed and torque. Consider factors like input and output shaft speeds.
- Select Gear Material: Choose appropriate gear materials based on factors like durability, wear resistance, and corrosion resistance. Common materials include steel, cast iron, and various alloys.
- Consider Efficiency: Evaluate the gearbox’s efficiency and select one that meets your energy efficiency requirements.
- Account for Load Conditions: Analyze the load conditions, such as constant or intermittent loads, shock loads, and starting and stopping frequencies.
- Check Lubrication Requirements: Consider the lubrication needs of the gearbox and ensure proper lubrication for smooth operation and longevity.
- Factor in Space Constraints: Consider the available space for installing the gearbox and choose a size that fits within your machinery.
- Assess Environmental Conditions: Evaluate the operating environment, including temperature, humidity, and exposure to dust or corrosive substances.
- Review Mounting Options: Determine the mounting options that work best for your machinery, such as foot-mounted, flange-mounted, or shaft-mounted gearboxes.
- Consult with Experts: Seek advice from gearbox manufacturers or engineers to ensure you make an informed decision.
Choosing the right gearbox is crucial for achieving optimal machinery performance, longevity, and reliability.
