Extrusion and Good Material Compatibility for Uniform Plasticization High-Precision Auger Screw for PP Pipes​


Auger Screw Function


The product possesses characteristics such as high efficiency, wear resistance, precision, and energy conservation, making it a preferred choice in the plastics processing industry. The extruder screw for blow molding machines is designed with optimization to ensure efficient extrusion and precise control. Manufactured using high-wear-resistant materials, it is durable and suitable for long-term continuous production. The screw parameters are precisely calculated, coupled with an advanced control system, to meet the demands of large-scale production.


The wear-resistant screw and barrel for HDPE pipes exhibit exceptional wear resistance and have undergone special treatment to enhance their hardness and service life. Efficient extrusion and precise temperature control ensure uniform plasticization of the plastic material, thereby improving product quality. Suitable for the production of pipes of various specifications, customized solutions are provided.


The screw and barrel for PP, PE, and PPR pipes feature good material compatibility, ensuring no chemical reactions occur during the extrusion process. High-precision extrusion results in uniform wall thickness and precise dimensions, enhancing the strength and sealing performance of the pipes. Designed with energy conservation and environmental protection in mind, it reduces energy consumption and carbon emissions, complying with environmental requirements.


Auger Screw Application


1.Automotive Industry:The extruder screws and barrels are used in the production of automotive parts such as fuel tanks, bumpers, and interior trim components made from plastic materials like HDPE, PP, and PE. The high efficiency and precision of the screws ensure consistent quality and dimensional accuracy of the parts.


2.Building & Construction:In the construction sector, these screws and barrels are essential for manufacturing pipes and fittings used in plumbing systems, irrigation, and drainage. The wear-resistant properties ensure long-term durability and reliability, particularly in HDPE and PPR pipe production.


3.Packaging Industry:The blow molding machines equipped with these screws are ideal for producing plastic containers and bottles for food, beverages, and household chemicals. The energy-saving design reduces operational costs, while the precise control allows for the creation of containers with tight tolerances and consistent wall thickness.


4.Agricultural Equipment:Agricultural machinery often requires durable plastic components such as tanks, housings, and covers. The extruder screws and barrels are used to manufacture these parts from materials like PP and PE, ensuring they can withstand harsh environmental conditions and frequent use.


5.Electronics & Electrical Industry:In the electronics industry, these screws and barrels are used to produce components such as cable conduits, electrical boxes, and junction boxes. The precision and consistency of the extrusion process are crucial for ensuring the electrical insulation and structural integrity of these part s.
