Twin Screw Extruder Machine Features:

Twin Screw Design: The twin screw design enables efficient material mixing and plasticization under complex processing conditions. The intermeshing and rotation of the twin screws can generate high shear forces, ensuring uniform mixing and plasticization of materials, and is suitable for processing a variety of high-viscosity and heat-sensitive materials.

Hydraulic Pressure System: The hydraulic pressure system ensures precise matching between the screw and the barrel and improves processing stability. By precisely controlling the hydraulic pressure, it can ensure that the gap between the screw and the barrel remains consistent during rotation, thereby improving the material conveying efficiency and processing accuracy.

Temperature Control: Equipped with 10 temperature control zones, each zone is independently controlled by the Omron controller to ensure temperature uniformity during processing. This precise temperature control can effectively prevent the material from degrading due to excessive temperature during processing, while ensuring uniform plasticization of the material.

Building Block Screw and Barrel: The screw and barrel adopt a building block design, which can be flexibly combined according to different process requirements to achieve multiple functions. This design allows users to adjust the configuration of the screw and barrel according to different processing tasks, thereby improving the adaptability and flexibility of the equipment.

Split barrel: The barrel can be split for easy cleaning and maintenance. The split design makes it easier to clean and maintain the barrel, reducing equipment downtime.

High shear mixing capability: The high-speed rotation of the twin screw generates high shear force, which can effectively mix high-viscosity materials. This high shear force can ensure that the materials are evenly mixed in a short time and improve production efficiency.

Self-cleaning function: The screw design has a self-cleaning function to reduce material residue and improve the cleaning efficiency of the equipment. The self-cleaning function can effectively reduce the residue of materials in the screw and barrel, thereby reducing the difficulty of cleaning and maintenance costs.

Multiple models can be customized: According to user needs, twin screw extruders of different models and specifications are provided to meet diversified production needs. Users can choose the appropriate model according to their specific needs, or customize a specific equipment configuration to meet specific production requirements.

Twin Screw Extruder Machine Applications:

Plastic modification: Twin Screw Extruder Machine is one of the important equipment for plastic modification. By adding different additives, fillers and reinforcing agents, modified plastics with specific properties such as flame retardant, reinforced, toughened, weather-resistant, etc. can be prepared. These modified plastics are widely used in automobiles, electronics, home appliances, construction and other fields.

Plastic coloring: In the process of plastic processing, Twin Screw Extruder Machine can achieve precise coloring control. By adding pigments or dyes together with plastic raw materials into the extruder, after melting, mixing and extrusion, plastic products with uniform color and bright color can be obtained. This coloring method has the advantages of high efficiency, environmental protection and low cost.

Plastic filling: In order to improve the rigidity of plastic products and reduce costs, inorganic fillers (such as calcium carbonate, talcum powder, etc.) are usually added to plastics. Twin Screw Extruder Machine can well achieve uniform dispersion and melt mixing of fillers to ensure the performance and quality of filled plastics.

Plastic reinforcement: By adding reinforcing materials such as fibers and particles to plastics, the mechanical properties and heat resistance of plastic products can be significantly improved. Twin Screw Extruder Machine has unique advantages in the preparation of reinforced plastics, and can achieve uniform dispersion and melt mixing of reinforced materials.

Reaction extrusion: Twin Screw Extruder Machine can also be used in the reaction extrusion process, that is, chemical reactions are carried out during the extrusion process to prepare polymer materials with specific properties. This method has the advantages of simple process, continuous production, and low cost, and has broad application prospects in the field of polymer synthesis and modification.

Other application areas: In addition to the above application areas, Twin Screw Extruder Machine can also be used to prepare special polymer materials such as biodegradable plastics, thermoplastic elastomers, and functional polymer materials. In addition, it is also widely used in food packaging, medical devices, aerospace and other fields.

Twin Screw Extruder Machine 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.

Twin Screw Extruder Machine Maintenance Tips:

• Regular cleaning: Clean the screw and barrel regularly to ensure that there is no residue during processing that affects the product quality. Appropriate cleaning agents and tools should be used during cleaning to avoid damage to the surface of the screw and barrel.

• Lubrication maintenance: Check and replace lubricants regularly to ensure the normal operation of the transmission system. The selection of lubricants should be based on the specific requirements and working conditions of the equipment to ensure the lubrication effect.

• Temperature calibration: Calibrate the temperature control system regularly to ensure the accuracy of the processing temperature. Professional calibration equipment and tools should be used during temperature calibration to ensure the accuracy of the temperature sensor.

• Screw inspection: Check the wear of the screw regularly and replace worn parts in time. During the inspection, attention should be paid to the degree of wear and damage on the surface of the screw. If necessary, it should be repaired or replaced in time.

• Electrical system inspection: Check the electrical system regularly to ensure the stability and safety of the equipment. During the inspection, attention should be paid to whether the connection of wires and cables is firm and whether the electrical components are working properly.

• Hydraulic system maintenance: Check the pressure and leakage of the hydraulic system regularly to ensure the normal operation of the hydraulic system. During the inspection, attention should be paid to the oil level and quality of the hydraulic oil, and the hydraulic oil should be replaced and the leakage parts should be repaired in time.

• Cooling system maintenance: Regularly check the operation of the cooling system to ensure the stability of the equipment under high temperature conditions. Pay attention to the level and quality of the coolant during the inspection, and replace the coolant and clean the cooling system in time.

• Operator training: Provide professional training for operators to ensure the correct operation and maintenance of the equipment. The training content should include the operating procedures, maintenance methods and safety precautions of the equipment to ensure that the operator can master the use and maintenance skills of the equipment.
