From masterbatch and engineering-plastics compounding to cable materials, wood-plastic composites and recycling — the right line depends on your material, additive loading and target pellet. Explore the applications we equip.
Colour, flame-retardant and functional masterbatch with high, well-dispersed additive loadings.
Calcium carbonate and talc incorporation, glass- and carbon-fiber reinforcement of engineering polymers.
XLPE and silane-crosslinkable compounds, insulation and sheathing, and low-smoke halogen-free materials.
Wood-plastic composites with high natural-fiber loadings and PVC compounding systems.
Compounding and alloying of engineering polymers and thermoplastic elastomers with reactive extrusion options.
Film reclamation and PET crushing, washing and drying into reusable pellets and flake.
Challenge: high, uniform additive dispersion without degrading pigment or carrier.
Recommended equipment: SJSH or DY co-rotating twin-screw extruder with side feeding and controlled venting.
Materials: PE, PP, PS, ABS, PA carriers with pigments, flame retardants or functional additives.
Pelletizing: water-cooled strand or air-cooled hot-face depending on output and pellet shape.
Challenge: incorporating high mineral-filler loadings or reinforcing fibers while preserving fiber length.
Recommended equipment: twin-screw extruder with gravimetric main feed, downstream side feeding for fillers or fibers, and vacuum venting.
Materials: PP/PA/PBT with calcium carbonate, talc, glass fiber or carbon fiber.
Pelletizing: water-cooled strand pelletizing for reinforced compounds.
Challenge: clean, homogeneous compounds for insulation and sheathing, including crosslinkable and low-smoke halogen-free systems.
Recommended equipment: tandem or two-stage lines with temperature control and gentle pelletizing.
Materials: XLPE, silane-crosslinkable PE, LSZH compounds.
Pelletizing: low-temperature strand or hot-face methods matched to the compound.
Challenge: high wood-flour or natural-fiber loadings with moisture removal.
Recommended equipment: one-step twin-screw or tandem twin/single-screw WPC lines with strong venting.
Materials: PE/PP/PVC with wood flour or natural fibers.
Pelletizing: hot-face or strand pelletizing depending on the profile downstream.
Challenge: reclaiming post-industrial film and PET into consistent, reusable pellets or clean flake.
Recommended equipment: single-screw reclamation and pelletizing lines; PET crushing, washing and drying lines.
Materials: LDPE/LLDPE/PP film, PET bottle and fiber scrap.
Pelletizing: strand or hot-face pelletizing for film; washing and drying for PET flake.
Reference throughput in kg/h for the SJSH co-rotating twin-screw platform, by process type and screw size. Use it to narrow the machine size before a detailed enquiry — figures are indicative and depend on formulation, filler loading, screw configuration and pelletizing method.
