Professional ABS Multilayer Co-extrusion Sheet Production Line Enables High-Performance Composite Material Manufacturing

We professionally provide complete solutions for ABS multilayer co-extrusion sheet production lines. This advanced equipment uses a dual-extrusion configuration of SJ-130/38 and SJ-70/35 extruders, specifically designed for producing multilayer composite sheets with widths of 500-2000mm. This ABS co-extrusion sheet equipment, through a precision distributor system, enables multilayer co-extrusion production of various structures such as A+B or A+B+A, achieving a stable output of 450-600kg/h. This mature multilayer co-extrusion production line provides reliable production equipment for the high-end sheet manufacturing field.

The core of this ABS multilayer co-extrusion sheet production line adopts a dual-extruder configuration. The SJ-130/38 main extruder is equipped with a 200KW drive motor, a screw diameter of 130mm, and an L/D ratio of 38:1, ensuring efficient plasticization of the main layer material. The SJ-70/35 auxiliary extruder is equipped with a 45KW motor, a screw diameter of 70mm, and an L/D ratio of 35:1, specifically for the precise extrusion of functional layers. The screw and barrel of the ABS co-extrusion sheet equipment are made of 38CrMoAL nitrided steel, with hardness reaching HV950 and HV1050, ensuring wear resistance and long-term stability when processing engineering plastics.

The die system of the ABS multi-layer co-extrusion sheet production line adopts a coat hanger-type flow channel design, with a die width of 2200mm and equipped with a precision distributor to ensure uniform material distribution in each layer. The three-roll calender is equipped with Φ450×2500mm mirror-finish rollers, with a roller surface hardness of HRC58-62 and a chrome plating thickness of 0.08mm. A special multi-channel design ensures uniform temperature. The roller temperature control system uses softened purified water as the medium, with a temperature control accuracy of ±1℃, and is equipped with three 2.2KW hot water pumps and three sets of 12KW heaters to provide a precise temperature environment for sheet forming.

The entire multi-layer co-extrusion production line also includes two hydraulic screen changers, an 8-meter cooling support, and a traction cutting system. The screen changer uses Taiwanese hydraulic components, enabling screen changes without stopping the machine. The traction machine is equipped with Φ240×2500mm nitrile rubber rollers, driven by a 2.2KW motor, achieving synchronous speed regulation with the three rollers. The electrical control system of the ABS co-extrusion sheet equipment uses a Siemens S7 series PLC and touch screen, combined with an ABB frequency converter, to ensure coordinated operation of the entire line.

We have equipped the ABS multi-layer co-extrusion sheet production line with a complete feeding and auxiliary system. The SJ-130 extruder is equipped with an E-1000 stainless steel screw feeder, and the SJ-70 extruder is equipped with an E-300 vacuum feeder, ensuring precise supply of different raw materials. The cooling support is equipped with 8-meter-long stainless steel rollers and three adjustable edge cutters, ensuring sufficient cooling of the sheet and neat edges. The cutting machine uses a mechanical electric shear, equipped with a Korean Autonics encoder, to achieve automatic fixed-length cutting.

This ABS multilayer co-extrusion sheet production line is not only suitable for ABS materials, but can also process various engineering plastics such as HIPS, PS, PP, HDPE, and PMMA, meeting diverse customer production needs.
