Plastic Lumber Making Machine

Yongte factoryhas developed specialized Plastic Lumber Making Machine that utilize 100% plastic waste as raw material—no wood flour filler required. These machines are capable of manufacturing plastic lumber profiles in diverse sizes and custom shapes, enabling direct processing of waste plastics into finished products without additional material blending.

As a turnkey waste plastic recycling solution, the equipment features easy operation, energy efficiency, and eco-friendliness. By converting plastic waste into high-value plastic lumber, it not only addresses waste disposal challenges but also supports circular economy goals, making it ideal for construction, landscaping, and outdoor furniture industries seeking sustainable production solutions.

Product Parameter (Specification)

Product features

1. SJ90 Plastic lumber profile extrusion line for continuously extruding plastic lumber planks: This machine is equipped with a single-screw extruder suitable for processing good recycled PP/PE/ABS flakes or granules, working together with a vacuum calibration and cooling tank, stably pulling off a tractor and auto cutter, so this line can produce plastic lumber products continuously, and the product length can be cut to any size. By vacuum calibration, the product made by this line has a good surface appearance and stable product shape. Therefore, the plastic lumber can be widely used for making outdoor furniture, such as lumber chairs, lumber sunbeds, lumber tables, and desks.

2. SH75 plastic lumber board extrusion line equipped with a parallel twin-screw extruder with a vacuum exhausting system and a force-feeding press, so it can work with mixed crushed plastic materials such as film/bag/flakes. By equipping a wide-width extrusion mold, calibration table, traction machine, and cutter, this line can produce a maximum width of 1200mm plastic lumber board with a thickness of up to 50mm. The product surface is also smooth and uniform by vacuum calibration, and the product length can also be cut to any size. The plastic lumber board product is widely used as a panel for desks and tables and can also be cut into small pieces of planks.

3. SJZ90 Plastic pole extrusion and molding machine can use plastic waste film/bags directly without crushing and washing processes. The large-diameter twin-screw extruder can ingest the plastic waste directly and melt it, then push the material into molds which are placed into a full water tank after being filled with the melted material. Thus, this machine can produce solid fence poles with round or square shapes, and the length of the fence pole is fixed by the melt mold, generally with a maximum length of 2500mm.
