Plastic Recycling Extruder Applications:

Plastic recycling and reuse:

Plastic recycling extruder plays a vital role in the field of plastic recycling and reuse. It can efficiently process various waste plastics, such as PET bottles, HDPE barrels, PP packaging bags, etc., into high-quality reusable particles through crushing, cleaning, melting and extrusion.

Engineering plastic modification:

In the field of engineering plastic modification, plastic recycling extruder plays an irreplaceable role. By adding various fillers, reinforcing fibers, flame retardants, plasticizers and other modifiers, plastic recycling extruders can change the original properties of engineering plastics, such as improving strength, hardness, wear resistance, impact resistance, etc., to meet the special needs of plastic products in different fields.

Masterbatch production:

Masterbatch is a concentrated pigment particle composed of pigment, carrier resin and additives, with excellent color brightness and dispersibility. In the production process of masterbatch, plastic recycling extruder plays a key role. It can fully mix the pigment and carrier resin, and evenly disperse the pigment in the carrier resin through high-temperature melting and extrusion process to form masterbatch.

Thermoplastic Elastomer (TPE/TPU) Processing:

Thermoplastic elastomer (TPE/TPU) is a new type of plastic material with rubber-like elasticity and plastic processing performance. In the field of TPE/TPU processing, plastic recycling extruders can produce soft and durable plastic products.

Mixing of highly filled materials:

When preparing highly filled materials, plastic recycling extruders can evenly disperse a high proportion of fillers (such as calcium carbonate, talcum powder, wollastonite, etc.) into plastics to ensure product stability and consistency. These fillers can not only improve the strength and hardness of plastic products, but also reduce production costs and density. At the same time, plastic recycling extruders can also achieve blending and modification of different types of fillers by adjusting process parameters and formula design, and develop new highly filled materials with special properties.

Plastic Recycling Extruder Types:

Co-Rotating Twin Screw Extruder: 

Both screws rotate in the same direction, offering efficient mixing and homogenization. Ideal for compounding, masterbatch production, and processing thermoplastic elastomers.

Counter-Rotating Twin Screw Extruder: 

Screws rotate in opposite directions, providing gentle mixing, suitable for processing materials like PVC.

Intermeshing Twin Screw Extruder: 

Screws engage with each other, enhancing mixing and shearing, perfect for high-viscosity materials and complex formulations.

Non-Intermeshing Twin Screw Extruder: 

Screws operate independently, providing lower shear, ideal for applications requiring minimal material stress.

Plastic Recycling Extruder Maintenance:

Regular Inspection and Maintenance:

Regular, comprehensive inspection and maintenance of the Plastic Recycling Extruder is crucial to ensuring long-term, stable operation. Inspections should include the wear and operating status of key components such as the screw, barrel, die, motor, and reducer. Routine inspections are recommended every 200 hours, and comprehensive maintenance is recommended every 1000 hours. If the screw or barrel is found to be worn more than 0.5mm during inspection, it should be repaired or replaced promptly.

Cleaning and Maintenance:

Maintaining equipment cleanliness is an essential component of maintenance. During production, plastic residue and dust should be regularly removed from the equipment surface to prevent accumulation that could affect heat dissipation and operating performance. When cleaning the screw and barrel, use specialized cleaning tools and solvents to thoroughly remove plastic deposits. Ultrasonic cleaning can be used for deep cleaning of difficult-to-reach areas.

Lubrication and Oiling:

Maintaining proper lubrication of the equipment is crucial for proper operation. Regularly lubricate and oil the equipment's moving parts, such as bearings, gears, and screws. Use high-quality grease and follow the manufacturer's recommended cycle and dosage. During lubrication, thoroughly clean the lubrication areas to prevent impurities from entering and causing poor lubrication.

Vacuum System Maintenance:

The vacuum system of the Plastic Recycling Extruder plays a vital role in ensuring product quality. Regularly check the vacuum pump's sealing and operating performance to ensure it can provide a stable vacuum level. It is recommended to check the vacuum pump's oil level and quality every 150 hours and replace the vacuum pump oil every 500 hours. During production, closely monitor changes in vacuum levels. If a drop in vacuum is detected, immediately shut down the machine for inspection and repair.

Cutting System Maintenance:

The cutting system is a critical component of the Plastic Recycling Extruder, and its condition directly affects the dimensional accuracy and appearance of the product. Regularly check the wear and sharpness of the cutting blades and replace worn blades promptly. Also, inspect the cutting system's drive motor and transmission to ensure smooth and precise operation. We recommend a routine inspection of the cutting system every 100 hours and a comprehensive maintenance every 500 hours.

Cooling System Maintenance:

The cooling system of the Plastic Recycling Extruder is crucial for stable equipment operation and product quality. Regularly inspect the cooling system's pumps, piping, radiators, and other components to ensure the cooling water flow and temperature meet process requirements. We recommend checking the cooling system's water quality and pressure every 100 hours and cleaning the cooling system's filters and radiators every 300 hours.
