Accessories
Designed for pelletizing PE, PP, ABS, PP-R, PA, PS, PC, PET, PVC, and other plastics.
Features
- Moisture-containing materials can be fed directly for melting and extrusion. The barrel houses two horizontal screws rotating in opposite directions, delivering strong feeding force and stable material pushing.
- Made from 38CrMo steel with nitriding treatment. Nitriding depth ranges from 0.5 to 0.8 mm for improved wear resistance.
- The feed section is fitted with special wear-resistant alloy inserts, extending service life under heavy-duty operation.
Used in extrusion, forming, and pelletizing processes for common plastics such as PP, PE, ABS, PA, PS, PC, and PET.
Features
- Manufactured from 38CrMoAlA or 42CrMo alloy steel and treated with a 120-hour carburizing process. Surface hardness reaches 900–1020 HV, helping extend service life under continuous operation.
- Screw diameters range from Φ30 mm to Φ200 mm. Multiple structural designs are available, including gradual type, abrupt type, barrier type, split-flow type, separation type, vented type, mixing type, single-flight, and multi-flight configurations. These options allow selection based on material characteristics to improve melting and plasticizing performance.
- The feed inlet is specially designed for faster material intake and stable output, supporting higher extrusion capacity and long-term durability.
This high-precision hardened gear transmission unit is designed to match plastic extruders. It includes an integrated thrust bearing system to handle axial load from the screw during operation. The gears and shafts are made from high-strength alloy steel. Each gear undergoes carburizing, quenching, and precision grinding. Gear accuracy meets GB10095-88 Class 6 standards, with surface hardness reaching HRC 54-62. A large thrust bearing is installed at the front of the hollow output shaft, which absorbs the axial force generated during extrusion. This maintains stable operation even under high loads.
Used in strand pelletizers, this high-speed rotating cutter trims extruded plastic strands into uniform pellets.
Features
- Made from tungsten-cobalt carbide grades such as YG-8 and YG-15. Hardness standard of HRC 65-70 provides strong wear resistance and long service life.
- The blade edge is finely ground for accurate cutting, helping maintain consistent pellet size when processing PE, PP, PVC, and other plastics.
Used in strand pelletizers, the pull rolls guide and transport cooled plastic strands steadily into the cutting section. Pull rolls produce consistent pellet length and have a huge impact on the pelletizing quality and process stability.
Features
- The surface of the pull roll is covered with rubber or silicone to improve grip and prevent slipping during operation.
- Designed with double bearings for improved stability and precision. Concentricity deviation is kept within ≤ 0.1 mm to ensure smooth rotation.
- Spring-controlled pressure adjustment allows the roll to handle different strand diameters without manual recalibration.
Ceramic band heaters provide stable and uniform heating for the extruder, helping plastic melt evenly during pelletizing. They are commonly used on both single-screw and twin-screw extruders.
Features
- Built with high-frequency ceramic insulation and a stainless-steel outer shell. Maximum working temperature can reach up to 800°C, with strong electrical insulation rated up to 1500V.
- Heating efficiency is higher than conventional heaters, reducing energy use by up to 30%. The outer surface temperature remains relatively low (≤60°C), improving operator safety.
- The modular design allows quick installation and replacement. Service life usually exceeds two years under normal operating conditions.
Bearings support rotating components such as screws and pull rollers to reduce friction and keep motion stable. They are widely used in extruders, pelletizers, and drive systems.
Features
- Equipped with a double casing (dual-lip seal combined with labyrinth sealing) with strong resistance against water and dust. Suitable for humid operating environments.
- Made from durable alloy materials such as 40CrNiMo, providing strong load-bearing capacity and a service life exceeding 20,000 operating hours under normal conditions.
- The external mounting design provides easy maintenance. Built-in temperature monitoring triggers an alarm automatically if operating temperature exceeds 65°C.
The mesh screen is used to remove impurities from molten plastic, such as metal fragments or particles that aren’t completely melted. It is commonly installed in extruder screen changers and melt filtration systems to improve pellet purity during plastic pelletizing. The screen is made from multi-layer woven stainless steel or carbon steel mesh. Mesh sizes range from 20 to 200 mesh, allowing selection based on material cleanliness and filtration requirements..
Used in crushers and pelletizers, these blades work together with rotating cutters to create the shearing force needed to cut plastic into uniform pellets.
Features
- Available in high-speed steel (W6Mo5Cr4V2) or composite steel construction (carbon steel body with a carbide cutting edge). Durable steel with hardness HRC 58–62 offers strong wear resistance.
- The blade edge is mirror-polished to reduce cutting resistance and help produce smooth pellets.
