TME 48/48 L Twin Screw Reverse Toothed Mixing Element 48x48mm Back Pressure Distributive Mixing Block

TME 48/48 L Twin Screw Reverse Toothed Mixing Element 48×48mm Backpressure Distributive Mixing Block

Product Description

TME 48/48 L is a reverse left-hand toothed mixing element for co-rotating twin screw extruders. It adopts 48mm lead and 48mm effective length to fit standard 48-series screw configurations.

First, it features a reverse staggered tooth structure. Different from forward types, it creates controllable melt backflow and builds stable local backpressure. Meanwhile, the tooth profile continuously splits, folds and recombines melt streams for thorough distributive mixing.

Besides, this design effectively extends material residence time inside the barrel. It fully disperses high-concentration additives, pigments and fillers, and eliminates volatile residues and particle agglomeration.

In addition, it maintains mild and stable shear force. It avoids excessive heat accumulation and polymer chain damage, so it supports reactive extrusion and devolatilization processes well.

Furthermore, precision machining ensures accurate spline fitting and stable operation. It uses wear-resistant nitrided steel as standard with multiple material options. The smooth polished surface reduces material adhesion and simplifies daily cleaning and material switching.

Overall, this compact reverse mixing element cooperates well with forward mixing and conveying blocks. It optimizes screw layout for high-filler compounding and modified plastic production.

Core Specifications

• Adopts reverse tooth structure, so it builds steady backpressure and extends melt residence time
• Provides full melt folding and splitting, thus achieving excellent dispersion for high-filler and high-colorant formulas
• Supports effective devolatilization and volatile removal, which improves finished product purity
• Generates moderate shear force, so it completes sufficient mixing without polymer thermal degradation
• Comes with polished smooth surface, so it minimizes material residue and lowers cleaning cost
• Matches diverse material options and universal spline design, so it adapts to complex compounding processes

It fits high-concentration color masterbatch compounding, reactive extrusion, biodegradable plastic modification, high-filler blending, devolatilization production and functional additive homogenization.
