Zoptymalizowana konstrukcja wytłaczarek dwuślimakowych do wysokowydajnego przetwarzania materiałów

Twin-screw extruders are essential tools in today’s manufacturing world, built to process plastics and advanced materials with top efficiency. At Nanjing Granuwel Machinery, we’ve designed these machines to tackle tough industrial jobs, offering durability and flexibility. With years of hands-on experience in extrusion technology, I’ll break down what makes our twin-screw extruders stand out, their key features, and how they perform across different uses.

Our twin-screw extruders use two rotating screws inside a barrel to melt, mix, and shape materials. Raw inputs—like plastic pellets or powders—move through heated zones under pressure. Specialized screw sections, such as kneading blocks or toothed elements, blend and shear the mix, while venting systems remove moisture or gases. The output is a consistent melt, ready for molding, pelletizing, or other processes. It’s a reliable system that handles basic polymers and complex composites alike.

These extruders come loaded with practical advantages:

• Screw Elements: Adjusted pitch and helix angles improve material flow and mixing. Unequal pitch setups create backflow, ensuring even blends fast.
• Kneading Blocks: Built for high-viscosity materials like TPE, they offer strong shear. You can tweak their layout for the exact mixing power needed.
• Elementy zębate: Perfect for powders, they spread fillers uniformly. Custom tooth designs cut down on clogs and uneven spots.
• Custom Configurations: Mix forward and reverse threads or add kneading blocks to control shear and flow. PE gets moderate shear; PVC stays low and short.
• Feeding Options: Volumetric feeding works for free-flowing materials; loss-in-weight handles sticky ones. Side feeders add fibers or additives at the right point.
• Venting Systems: Natural vents manage low-volatility mixes; forced vents clear out high-moisture loads for clean results.

A 2024 Plastics Engineering report found twin-screw extruders boost mixing efficiency by 35% over single-screw models—our units prove that every day.

Here’s what you gain:

• Speed: High shear and precise controls shorten processing times without cutting corners.
• Adaptability: They handle everything from elastomers to nanocomposites with ease.
• Toughness: Precision screws and sturdy barrels stand up to heavy, abrasive loads.

A TPE plant using our extruder cut cycle times by 20%, thanks to tailored kneading and venting setups.

Thermoplastic Elastomers (TPE)

TPE demands solid mixing and exact heat. Our machines offer:

• Even filler spread for reliable elasticity.
• Tight temp controls to prevent scorching.
• Forced venting to stop bubbles.

Engineering Plastics

Modifying PA or PC? We’ve got solutions:

• Smooth blending of toughening agents.
• Cost-saving fillers without jams.
• Stabilizers for longer-lasting products.

Nanocomposites

For high-tech fields like aerospace, precision is key:

• Nanofillers mix evenly with strong shear.
• Temp settings preserve material properties.
• Gas venting keeps output flawless.

Biodegradable Materials

Eco-friendly plastics stay strong with:

• Gentle handling to avoid breakdown.
• Accurate heat for sensitive resins.
• Clean venting for perfect results.

A packaging company processing biodegradable blends saw a 15% quality boost with our custom screw designs.
