Twin Screw Compounding Line

Description

A twin screw compounding line is an industrial processing system that melts, mixes, modifies, and homogenises polymer materials using two intermeshing screws inside a twin screw extruder. The line combines polymer resins with additives, fillers, fibres, pigments and other functional materials to produce compounded plastic pellets with controlled physical, mechanical and processing properties.

A typical line consists of a feeding system, a twin-screw extruder, dosing and mixing units, heating and cooling systems, an extrusion die, a pelletising system and a control system. The two screws provide efficient conveying and mixing, allowing manufacturers to achieve consistent material composition and stable processing performance.

Depending on the formulation and production requirements, the line can process materials such as polypropylene (PP), polyethylene (PE), acrylonitrile butadiene styrene (ABS), polyamide (PA), polycarbonate (PC), polybutylene terephthalate (PBT), thermoplastic polyurethane (TPU), and other thermoplastics. It is widely used in the production of modified plastics, engineering plastics, masterbatches, fibre-reinforced compounds, flame-retardant materials, and recycled polymer compounds.

High Filler Pelletizing Line With High Capacity Series

High Filler Masterbatch is made of talc, calcium carbonate, kaolin, and other inorganic powder compounding with resin and lubricants through twin-screw pelletization. It is widely used in polyethylene, polypropylene, polyvinyl chloride, polyester, ABS, PS, EVA blown barrels, pipes, wire series, films, strapping, injection molding, extrusion, and so on. High Filler Masterbatch has these properties: enhanced incremental cost reduction, improved heat resistance, and a low-carbon environment.
High Filler Masterbatch can be divided into PP calcium carbonate filler, PE calcium carbonate filler, talc filler, and transparent filler.

Biodegradable Plastic Compounding Machine

Product advantages

Underwater pelletizing system

The advanced underwater pelletizing system stably cuts out elliptical particles, with a high degree of automation, and the fully enclosed system does not emit smoke or dust to the environment and can adapt to various output requirements.

Metering system

Degradable plastics, filled starch, and plasticizer glycerin are accurately measured by an independent metering system and then added to the twin-screw extruder, which has a high degree of automation and strong flexibility in formula adjustment.

Downstream auxiliary machine

Abundant and reasonable downstream auxiliary equipment design effectively homogenizes, screens, dries, and cools the finished products, and finally packs them into bags, all in one go, automatically and compactly.

Compounding system

The modular twin-screw extruder is equipped with an ultra-high torque gearbox, abrasion-resistant, corrosion-resistant, and high-precision barrel screw, high-strength mandrel and safety coupling, high-efficiency heating, and precise control to ensure that the equipment is stable and reliable for a long time run.

PU/TPU Reaction Extrusion Series

According to the PUATPU raw material rheological characteristics, we made a lot of efforts on the barrel processing accuracy and barrel cooling effect. Meanwhile, we updated and redesigned the core parts, so that we basically solved some bottleneck problems in the production process. The reaction efficiency and output capacity have been improved sharply, and customers approve of it.
