The barrel is constructed from durable, corrosion-resistant alloys, ensuring that the extruder can handle high temperatures and abrasive materials over time. |
The SJSZ80-156 conical twin screw extruder works through a multi-step process that involves feeding, melting, mixing, and shaping the plastic material. Here’s a basic breakdown of the process:
![]() | 1. Material FeedingPlastic pellets or powder are fed into the extruder’s hopper, where they are directed into the barrel. The hopper is designed to ensure a consistent feed rate, preventing material blockages or inconsistencies that could affect the extrusion process. |
![]() | 2. Melting and PlasticizingAs the material moves along the barrel, the rotating screws begin to melt it through a combination of mechanical shear and heat. The conical screw design promotes gradual compression, which helps to evenly distribute the heat and ensures that the material is plasticized uniformly. The screws are engineered to maintain a consistent flow and minimize melt degradation. |
![]() | 3. Mixing and HomogenizationThe intermeshing screws work to mix the molten material, ensuring uniform dispersion of any additives, colorants, or fillers. This is particularly important when producing compounds or colored plastics, as it ensures that the end product has consistent properties throughout. |
![]() | 4. Shaping and FormingAfter the material is melted and homogenized, it is forced through a die that shapes it into the desired product, such as a pipe, profile, sheet, or film. The die determines the final shape and dimensions of the extruded material, and the SJSZ80-156 extruder is capable of working with a wide range of dies for different product types. |
![]() | 5. Cooling and SolidifyingAfter leaving the die, the extruded product is cooled to solidify it. For most applications, this is achieved by passing the extruded material through a cooling bath or using air cooling systems. The cooling process helps to maintain the shape and size of the product, ensuring dimensional accuracy. |
![]() | 6. Cutting or WindingFinally, the cooled, solidified product may be cut into specific lengths or wound into coils, depending on the type of product being produced. In some cases, additional downstream equipment such as cutting machines or winders are used to further process the extruded material. |
