• Advanced hydraulic screen changing system: The hydraulic pressure screen changer can quickly replace the screen without stopping the machine, and the screen changing time is shortened to less than 1/3 of the traditional method. This technical advantage not only reduces the production interruption caused by screen changing, but also reduces the labor intensity of operators and improves the automation of the production process. In large plastic recycling companies, frequent screen changing operations are a key factor affecting production efficiency, and the hydraulic screen changing system of PP Extruder Machine can increase monthly production time by 10% - 15%, significantly improving the company's production capacity. At the same time, the hydraulic screen changer has a strong filtering ability, which can effectively remove impurities in the plastic melt to ensure the purity and quality of the output particles. Its filtering accuracy can reach below 0.1 mm, and it can filter out dust, sand and other impurities in the plastic raw materials, so that the surface of the produced plastic particles is smooth and flawless, meeting the production requirements of high-quality plastic products.

  
  

• Excellent durability: The screw and barrel are the core components of the extruder. They are made of SACM-1 alloy steel and have extremely high hardness and wear resistance after a special heat treatment process. The service life of the screw can reach 8000-10000 hours, and the service life of the barrel can reach 10000-12000 hours, which is much higher than the industry average. When processing highly abrasive plastic raw materials such as glass fiber reinforced plastics, the screw and barrel of SACM-1 can maintain stable performance, reduce production failures caused by component wear, and reduce equipment maintenance costs. The overall equipment adopts a sturdy frame structural design to ensure stability and durability in high-intensity production operations. Its body is welded with thick steel plates. After precise machining and strict quality inspection, it can withstand the huge pressure and torque generated by the screw extrusion, ensuring that the equipment will not deform or loosen during long-term use, providing a solid foundation for the production process.

  
  

• Optimized screw design: The length-to-diameter ratio (L/D) of the screw reaches 33:1. This optimized design significantly improves the mixing and plasticizing effect of the plastic melt. During the extrusion process, the plastic raw materials can be fully sheared, mixed and melted under the action of the length-to-diameter ratio of the screw, ensuring the uniformity and consistency of the plastic particles. Compared with the traditional screw with L/D ratio of 20:1, the screw of PP Extruder Machine can improve the mixing uniformity of plastic melt by 25% - 30%, effectively reduce defects such as silver wire and black spots in the particles, and improve product quality. The optimized screw design allows the plastic raw materials to be heated evenly and fully plasticized during the extrusion process. Its plasticizing capacity is 20% - 25% higher than that of the traditional screw, which can ensure that the plastic particles have good melt index and processing performance. Especially when processing high-performance engineering plastics such as ABS and PC, the optimized screw design can give full play to the performance advantages of the material and produce plastic particles that meet strict quality standards.

  
  

• High-speed operation and high output: The screw speed of PP Extruder Machine can reach 120 - 180 rpm, and it runs smoothly with low vibration.

Under the same configuration and energy consumption conditions, the output of PP Extruder Machine is 20% - 30% higher than that of similar equipment. This advantage is due to its optimized screw design, efficient transmission system and precise temperature control system, which enables the plastic raw materials to be fully plasticized and mixed during the extrusion process, reducing energy loss and improving production efficiency. For example, in a medium-sized plastic processing enterprise, after using PP Extruder Machine, the monthly output of plastic particles can be increased by 50 - 80 tons, which has brought significant economic benefits to the enterprise.

  
  

• High energy efficiency: The equipment is equipped with a 110KW variable frequency motor, which can automatically adjust the speed according to production needs to achieve energy-saving operation. Compared with traditional fixed-speed motors, variable frequency motors can save 30% - 40% of electricity when running at partial load. When the production task is light, the frequency conversion motor can automatically reduce the speed and reduce energy consumption; when it is in full load production, it can provide sufficient power guarantee to ensure production efficiency. This intelligent energy-saving drive system not only reduces the operating costs of enterprises, but also helps to reduce carbon emissions, which meets the requirements of sustainable development. The 8-segment independent temperature control system uses ceramic heating rings and air cooling fans (370W×12 pcs), which can quickly and evenly heat the barrel and effectively control the temperature fluctuation within the range of ±1℃. Compared with traditional heating and cooling systems, this system can improve heating efficiency by 20% - 25%, shorten preheating time by 30% - 35%, reduce heat loss and reduce energy waste. The precise temperature control system ensures the optimal processing temperature of plastic raw materials during extrusion, improves the plasticizing effect and product quality, and further improves the energy utilization efficiency of the equipment.

  
  

• Accurate process control: PP Extruder Machine is equipped with 8-segment independent temperature control system, which can accurately control the temperature of each section of the barrel. The control accuracy of each section temperature can reach ±0.5℃, ensuring the temperature uniformity and stability of plastic raw materials during extrusion. This precise temperature control is particularly important for different types of plastic raw materials. It can meet the processing requirements of various plastics such as PP, PE, ABS, PC, etc., and produce plastic particles that meet specific performance indicators. The equipment uses a frequency converter for speed adjustment, which can accurately control key parameters such as screw speed and feeding speed. The operator can set the appropriate speed and feeding amount on the control panel according to the characteristics of the plastic raw materials and production requirements to realize the automation and intelligence of the production process. Compared with the traditional mechanical speed regulation system, the frequency conversion speed regulation system has the advantages of high speed regulation accuracy, fast response speed, and smooth operation, which can effectively improve production efficiency and product quality.

  
  

• High-quality particle forming system: The particle cutting machine is equipped with SKD-11 high-speed steel tools with a hardness of up to HRC60-62, ensuring a stable and efficient cutting process. The speed of the cutting machine can reach 1500-2000 rpm, which can produce plastic particles with uniform size and smoothness. Compared with ordinary tools, the service life of SKD-11 high-speed steel tools is extended by 2-3 times, reducing the frequency of tool replacement and maintenance costs. For example, when producing PP plastic granules, efficient cutting equipment can ensure that the length error of the granules is controlled within ±0.5mm, meeting the production requirements of high-quality plastic products. The vibrating screening machine is made of stainless steel and equipped with three layers of screens, with the upper screen hole diameter of Φ6mm and the lower screen hole diameter of Φ1.5mm, which can accurately screen plastic granules.
