SME 48/48 R Forward Double Notch Slotted Mixing Element 48x48mm Low Shear Twin Screw Block

SME 48/48 R Forward Double Notch Slotted Mixing Element | 48×48mm Low Shear Twin Screw Block

SME 48/48 R is a professional forward double notch slotted mixing element designed for 48-series co-rotating twin screw extruders. It features 48mm lead and 48mm effective length, adopting an upgraded double-head slotted thread structure compared with single-notch mixing blocks. First of all, the forward thread structure ensures fast and stable melt conveying to support smooth continuous extrusion. Meanwhile, the symmetrical double notches create uniform mild melt backflow.

Therefore, this element achieves stronger distributive mixing effect while retaining low-shear characteristics. It repeatedly splits, stretches and recombines polymer melt layers to disperse pigments and additives evenly. Besides, the double-notch symmetrical design delivers more balanced mixing force than single-slot styles. It avoids material dead zones and local overheating, making it an excellent transitional mixing component for high-stability plastic compounding production.

• Upgraded Double Notch Mixing: Symmetrical double-slots structure provides more uniform melt splitting than single-notch elements. It improves mixing efficiency significantly without sacrificing conveying stability.
• Dual Conveying & Mixing Performance: Forward thread guarantees steady material forwarding and stable output. Controlled mild backflow from double notches eliminates uneven mixing and particle agglomeration.
• Ultra-low Shear Protection: Gentle mixing principle generates minimal shear heat. It effectively protects heat-sensitive polymer chains and prevents thermal degradation, yellowing and material breakdown.
• Balanced Extrusion Pressure: Double-sided symmetrical slot layout balances melt flow and pressure distribution. It avoids flow fluctuation and ensures consistent finished product quality.
• Smooth Transitional Effect: It perfectly connects conveying sections and intensive mixing sections. It optimizes screw gradient combination and stabilizes overall extrusion rhythm.
• Low Residue & Easy Maintenance: Polished thread and notch surfaces reduce material adhesion. It shortens purging time and improves efficiency during frequent color and formula switching.
• Wide Material Adaptability: Multiple wear-resistant and food-grade material options adapt to ordinary, high-wear and food-safe compounding working conditions.

This double notch slotted mixing element suits medium and high-stability compounding production. It applies to color masterbatch homogenization, PLA/PBAT biodegradable plastic blending, TPE/TPU soft elastomer modification, low and medium filler plastic compounding, heat-sensitive material extrusion and continuous stable industrial extrusion production.
