Plastic extruders are fundamental equipment in the manufacturing industry, transforming plastic raw materials into a wide variety of finished products through an efficient and continuous process. These machines, especially twin-screw extruders, offer benefits such as versatility in the production of plastic profiles, the ability to work with different types of materials and the possibility of customizing the mechanical and aesthetic properties of the final product.<\/strong> The use of these technologies not only optimizes production times but also contributes to the reduction of operating costs and improves process sustainability by minimizing waste.<\/p>\n

\"single<\/p>\n

Before starting the technical comparison between the parallel and conical twin screw extruder, it is important to highlight that our company, Gesti\u00f3n de Compras, has more than a decade of experience in the development, design and manufacture of this type of machinery<\/strong>. Our track record<\/a> is a reflection of our commitment to quality and innovation, offering our customers extrusion equipment that stands out for its performance, durability and compliance with the most demanding industry standards. We are proud to be a strategic partner in the search for extrusion solutions that drive our customers’ competitiveness and efficiency in the global marketplace.<\/p>\n

The screw structure is different<\/h3>\n
    \n
  • The screw structure is different Diameter: the head and tail diameters of parallel twin screw is the same. The diameter of small end of conical twin screw is different from that of big end<\/li>\n
  • Center distance: the center distance of the parallel twin screw is the same, the two axes of the conical twin screw present an angle, and the size of the center distance changes along the axis.<\/li>\n
  • Length diameter ratio: parallel twin screw (L \/ D) refers to the ratio of the effective part length of the screw to the outer circle of the screw, and the conical twin screw (L \/ D) refers to the ratio of the effective part length of the screw to the average value of the large end diameter and the small end diameter<\/li>\n<\/ul>\n

    Energy consumption<\/h3>\n

    On the premise of the same output, the parallel twin-screw extruder is more energy-saving.<\/p>\n

    For instance, Both PS130-28 (parallel twin-screw extruder) and SJSZ110-220 (conical twin-screw extruder) can produce 40 Tons of SPC floor per day, but the main engine power of PS130-28 is only 110KW, while that of SJSZ110-220 is 200KW. Therefore, the parallel twin-screw extruder is more energy-saving<\/p>\n

    \"Parallel

    Twin screw extruders service life<\/h3>\n

    Because of the head and tail diameter of conical twin screw is different. Therefore, under the same service time, the wear of conical twin screw is more serious than that of parallel twin-screw.<\/p>\n

    The service life of conical twin screw is generally 3 months. The service life of Gesti\u00f3n de Compras brand parallel twin screw is more than 6 months (The life of screw is guaranteed to be 6 months. If it is broken within 6 months, it will be replaced free of charge).<\/p>\n

    At the same output, the cost of the Parallel Twin Screw used in the extruder is only 75% of the conical twin screw. For example, the price of PS130-28 screw is only 75% of that of SJSZ110-220 screw.<\/p>\n

    \"Conical

    Plasticization performance<\/h3>\n

    The screw length of parallel twin-screw extruder is longer than that of conical twin-screw extruder, so the plasticizing effect of parallel twin-screw extruder is better, and the kneading of materials is more uniform.<\/p>\n
