    1. Single Screw ExtruderDozens of plastic materials can be extruded by this 2-stage single screw extruder. HDPE, PP, ABS, PVC, PET, PC, and PS are just a few examples.
    1. Conical Twin Screw ExtruderFor customers with heavy plastic extrusion tasks, our LSZ series twin screw extruder is probably your best bet. It outperforms conventional single-screw extruders in self-cleaning, raw plastic feeding, ventilation, enabling chemical reaction, and aggressive mixing and melting.
    1. HDPE Gas Pipe/Water Pipe Extrusion LineThe HDPE pipe extrusion line comes with a unique extruder screw and grooved barrel, which are specially designed to cope with high density polyethylene materials.
    1. PE/PERT/PPR Water Pipe Extrusion Line

      A variable frequency drive is used to facilitate motor speed adjustment so that the speed of our PPR pipe extrusion line matches the output requirement. As a matter of fact, the main electric parts on this extrusion line are all of well-known imported brands.

    1. Steel Wire Reinforced PVC Hose Extrusion LineSteel wire reinforced PVC hose is made up of the spiral steel wire incorporated within the wall of flexible PVC tubing. Glass-like clarity makes this hose a real eye-catcher. Resilient and non-toxic, the hose often operates within an allowable temperature range of between -10°C and 65°C.
    1. Spiral Reinforced PVC Hose Extrusion LineThe spiral reinforced PVC hose extrusion line is mainly comprised of the extruder, spiral coil forming machine, spray tank, haul-off, and the take-up machine.
    1. UPVC Double Pipe Extrusion LineLeader Machinery is a specialist manufacturer of pipe extrusion equipment. Its UPVC double pipe extrusion line is made up of the LSZ51, LSZ105, LSZ65 or LSZ132 conical twin screw extruder, extrusion die, and other downstream components.
    1. DGD Series PE Drip Irrigation Pipe Extrusion LineA few years back, Leader Machinery saw the huge potential in Chinese drip irrigation tubing market. To capitalize on this potential, the company has invested considerable effort in the research and development of DGD series PE drip irrigation tubing extrusion line.
    1. PP/PE/PU/PVC Medical Hose Extrusion LineThis catheter extrusion line uses an ST-45×25 extruder for efficient extrusion of catheter from PP, PE, PU, and PVC resins. Both the extruder and marking machine adopt the variable frequency drive to ensure the speed at which extrusion is done stays consistent.
    1. PE/PP/PVC Single Wall Corrugated Pipe Extrusion LineThis corrugated pipe extrusion line mainly uses the PVC, PP, and PE as raw materials to produce small-size single-wall pipes with ridges and grooves on their surface.
    1. HDPE/ PVC Double Wall Corrugated Pipe Extrusion LineThis series of corrugated pipe extrusion line uses high-density polyethylene or PVC as raw plastics to produce large-size double walled pipes with corrugations on their exterior.
    1. HDPE Large Diameter Hollow Wall Spiral Winding Pipe Extrusion LineThe resultant pipes produced by our extrusion equipment are characterized by their unique plastic H sections which give the whole structure enhanced rigidity around its circumference as well as maximum impact strength.
    1. PP/PE/PS/ABS/PVC Single Layer/Multi-layer Sheet Extrusion Line

      There are many benefits involved in the use of our plastic sheet extrusion line. Proper shearing, high plasticizing efficiency, and intensive heating and mixing are just a few.

    1. PET/PBT Single Layer/Multi-layer Sheet Extrusion LineDiscarded PVC sheets, whether they are landfilled or burned, would do harm to the environment. In comparison, PET sheets contain only three elements: C, H, and O. They are totally recyclable and won’t leave any residuals or toxic gases after being burned.
    1. PVC Free Foam Sheet Extrusion LineDownstream components on this free foam sheet extrusion line include the vacuum calibrating bench, belt haul-off, edge-trimmer, slitting saw, and pallet rack.
    1. PVC/WPC Celuka Foam Sheet Extrusion LineCompared with free foaming process, the Celuka technology produces more flat, smooth outer surface with better stiffness, rigidity and mechanical strength.
    1. PP/PE/PC Hollow Grid Sheet Extrusion lineThe hollow grid sheet extrusion line, or twinwall sheet extrusion line, takes PP, PE, PC, and PVC as raw plastics to produce fluted sheets with a choice of width ranging from 1300mmm to 2100 mm and thickness from 2mm to 10mm.
    1. PVC/PP Corrugated Sheet Extrusion LineOutstanding corrosion-resistant and weatherproof characteristics make the corrugated sheet a top choice for use as the roofing of workshops, warehouses, and car sheds.
    1. HDPE Geomembrane/Waterproof Sheet Extrusion Line

      The cast stretch film technology allows our waterproof sheet extrusion line to use LLDPE, LDPE, MDPE, HDPE, EVA, ECB, or TPO as raw plastics and subject them to thermal extrusion, calendering, cooling, and sizing.
