Product Description Product DescriptionThe main screw and barrel of the split twin screw extruder adopt advanced "building block" design. The screw is composed of various screw blocks installed on the core shaft and inner lining of the cylinder, forming a sleeve that can be adjusted according to different screw blocks. The ideal structure of the screw components can be flexibly combined according to the process requirements of the material variety, achieving the transportation, refining, shearing, and discharging of materials. This effectively solves the contradiction between the universality and specificity of the screw that is difficult to consider and achieves the goal of one machine with multiple functions. Another advantage of the "building block" design is that worn screw and cylinder components can be partially replaced, avoiding the scrapping of the entire screw or cylinder, greatly reducing the maintenance costs.1. Segments and Functions of the Screw: The screw is generally divided into five segments: feeding segment, melting segment, mixing segment, venting segment, homogenizing segment.1. Feeding segment:This segment is responsible for conveying the material and preventing overflow.2. Melting segment:In this segment, the material is fully melted and homogenized through heat transfer and frictional shear.3. Mixing segment:The mixing segment further refines and homogenizes the size and distribution of the material components,creating an ideal structure with dispersion and distribution mixing functionality.4. Venting segment:This segment is used to exhaust impurities such as water vapor and low molecular weight substances.5. Homogenizing (metering) segment: The homogenizing segment is responsible for conveying and pressurizing the material, increasingthe density of the material at the extruder outlet to a certain extent, establishing a certain pressure, and achieving more thorough mixing to ultimately achieve a stable foundation.Product NameBarrels for Extruded machineryMaterial1)45 # steel 2)42CrMo steel 3)Nitrided steel (38CrMoAl) 4) 6542 (W6Mo5Cr4V2) 5) 304 food grade stainless steel. 6) 316 high-end stainless steelBrandTOPLINEAfter-sales Service1 YearKey Selling PointsSustainable,durableDetailed Photos1. The screw should have the appropriate flight depth, pitch, and compression ratio to achieve the desired melting and mixing characteristics. Efficient melting and mixing help ensure uniformity and homogeneity of the melted material, which translates into improved product quality.2. It is essential to control the residence time to avoid thermal degradation or over-processing of the material, which can negatively impact product properties. The screw and barrel configuration can be optimized to achieve the desired residence time and minimize any adverse effects.3. The choice of screw design, such as the use of barrier screws or venting, can help optimize pressure distribution and control, leading to improved product quality. This ensures thorough mixing of components and prevents pressure variations that could result in uneven curing, voids, or surface defects in the extruded silicone products.4. Material Compatibility:The screw and barrel should be selected based on the specific material being extruded to ensure compatibility. The geometry, surface treatment, and material of construction should be chosen to minimize material degradation, shear heating, or excessive wear. Proper material compatibility helps maintain product quality and prolong the life of the screw and barrel.ApplicationCharacteristic1. Customizable:The Barrel could be customized based on various requirements, with a variety of materials and processing methods to be chosen from. 2. Adaptable: The barrels could be fully replaced with original equipment parts 3. High quality: The barrel products hold high quality and have a longer lifespan compare with other barrels of the same price. 4.
