48mm Lead 24mm Length SME 48/24 R Short Slotted Thread Mixing Block for Twin Screw Extruder
SME 48/24 R is a short-type forward slotted mixing element for 48-series co-rotating twin screw extruders. It features a large 48mm lead and ultra-short 24mm effective length, adopting optimized single-slotted thread structure. Different from standard long mixing blocks, this short-version design occupies minimal screw space while retaining basic distributive mixing capacity.
First of all, the large-pitch forward thread delivers fast melt forwarding speed to support high-throughput extrusion. Meanwhile, the precision slot structure produces mild and controllable melt backflow. Therefore, this element balances rapid conveying and lightweight homogenization. It effectively disperses fine additives and eliminates tiny material agglomerations. Besides, its compact size enables flexible screw layout adjustment, making it ideal for fine-tuning extrusion rhythm without increasing screw resistance.

- Large Lead High-throughput Design: 48mm large pitch greatly improves melt conveying efficiency. It supports high-speed continuous extrusion and effectively boosts overall production output.
- Ultra-short Compact Structure: 24mm short length saves screw barrel space. It allows flexible layout adjustment and fine optimization of screw combination without changing the main process section.
- Lightweight Low-shear Mixing: Adopts mild slotted backflow mixing mode. It generates almost no extra shear heat and avoids polymer thermal degradation, perfectly protecting heat-sensitive materials.
- Fine Homogenization Effect: The precision notch structure splits melt streams evenly. It disperses tiny additives, lubricants and colorants to improve finished product surface smoothness.
- Low Resistance & Stable Flow: Short structural design brings minimal extrusion resistance. It avoids melt pressure fluctuation and maintains stable extrusion rhythm.
- Easy Cleaning & Low Residue: Polished thread and slot surfaces reduce material adhesion. It shortens purging time and improves efficiency during frequent formula switching.
- Flexible Matching Performance: It cooperates well with long mixing blocks and kneading elements. It serves as auxiliary fine mixing unit to optimize overall compounding effect.
This short large-lead slotted element suits high-output and fine-tuning extrusion processes. It applies to high-volume masterbatch finishing homogenization, biodegradable plastic high-speed compounding, TPE/TPU soft material fine mixing, low-filler plastic modification, heat-sensitive material extrusion and screw layout fine adjustment for stable production lines.

A1: It combines 48mm large lead high conveying capacity and 24mm ultra-short compact size. It improves extrusion output and realizes fine auxiliary mixing, meanwhile saving screw space for flexible process optimization.
A2: SME 48/48 R is full-length for main homogenization. SME 48/24 R is a short version with lower resistance and faster conveying speed. It mainly acts as auxiliary fine mixing and screw layout adjustment without excessive mixing shear.
A3: It fits high-volume production lines that require both fast output and fine material dispersion. It is widely used for post-section finishing mixing and process fine-tuning of heat-sensitive and low-filler materials.
A4: No. This element is positioned for auxiliary fine mixing instead of intensive mixing. It effectively eliminates tiny particle agglomerations on the premise of ensuring high conveying speed, which improves finished product smoothness.
A5: Yes. We support custom inner spline parameters, wear-resistant coating and multiple material upgrades to adapt to high-wear, corrosion-resistant and food-grade extrusion requirements.
If you need compact high-output auxiliary mixing elements to fine-tune your screw layout and improve production efficiency, SME 48/24 R short slotted mixing block is your ideal choice.
