Global carbon neutrality policies push plastic manufacturers to raise the proportion of recycled plastic raw materials. Waste plastic contains a large amount of impurities and hard fillers, which cause severe abrasion to ordinary nitrided screw barrels. The market demand for high wear-resistant bimetallic screw barrels keeps rising rapidly.
NINGBO JIACHENG INDUSTRY CO., LIMITED takes full advantage of its bimetallic welding technology advantages to produce alloy-lined screw barrels specially optimized for recycled plastic processing. A thick layer of wear-resistant alloy is welded on the inner surface of barrels and screw flight surfaces, greatly improving anti-abrasion and anti-corrosion capacity when processing mixed recycled PE, PP and PVC materials.
Compared with single nitrided screw barrels, JIACHENG bimetallic series can extend service life by over 2 times under long-term recycled material production conditions. The company supplies customized bimetallic screw barrel solutions to dozens of recycled plastic pelletizing factories across Southeast Asia and Europe, effectively helping clients lower spare parts replacement frequency.
The enterprise integrates independent R&D capability, mature manufacturing equipment and strict quality testing procedures. Its product lineup covers nitrided barrels, bimetallic barrels, chrome-plated barrels and complete twin-screw assemblies, fully matching injection molding machines, single-screw extruders and rubber processing equipment. Supported by stable product performance and global after-sales service, JIACHENG maintains long-term cooperative partnerships with plastic machinery enterprises all over the world, and keeps expanding its market share in the recycled plastic supporting parts sector.
