Twin-Screw Extruder (Standard)

This twin‑screw extruder is specially used for PP material compounding as the upstream pretreatment equipment for the PP honeycomb board extrusion line. Polypropylene pellets together with functional additives are accurately metered and fed into the twin‑screw barrel. Under controlled screw speed and barrel temperature, the materials get thorough plasticization, homogenized mixing and modification inside the extruder barrel.

After compounding, the modified PP material is directly discharged and supplied as feedstock for the subsequent PP honeycomb board extrusion line. Pre‑compounding by twin‑screw unit ensures even dispersion of modifiers, fillers and anti‑impact ingredients. It effectively solves common defects including uneven board brittleness, inconsistent hardness and color deviation that frequently occur during honeycomb panel forming.

Precise temperature‑zone control and adjustable screw rotation speed make it convenient to tweak material formulation for different finished‑board requirements. Whether you need higher‑impact‑resistant grade for pallet‑sleeve‑box panels or stiff‑grade for construction protection boards, the compounding process can be adapted accordingly.

Using this upstream twin‑screw compounding extruder helps stabilize the physical properties of your raw feedstock. It reduces fluctuation risks on your downstream honeycomb extrusion line, lowers scrap‑rate in continuous mass‑production, and delivers consistent‑quality PP honeycomb panels for packaging, automotive and construction‑related end‑use markets.
