Global purchasng demands keep climbing for our PP honeycomb board production line, which adopts innovative six independent single-screw co-extrusion configuration as core technical highlight, standing out from ordinary dual-extruder honeycomb equipment on the market. Each single-screw unit is independently equipped with separated feeding, heating and plasticizing control system; six sets of extruders feed core honeycomb layer and two surface skin layers synchronously under precise flow matching, realizing one-step continuous composite forming of sandwich honeycomb panels without secondary hot-press bonding. All screw and barrel components adopt nitrided alloy steel for wear resistance, with segmented precise temperature regulation from feeding zone to metering zone, effectively avoiding uneven plasticization, bubbling or delamination of finished boards, greatly improving finished product yield and long-term equipment operation stability. The whole line matches imported PLC intelligent control cabinet, servo traction unit and flying cutting system, supporting adjustable board thickness from 5mm to 35mm and customized effective width up to 2200mm, with stable hourly output ranging from 130kg to 480kg, and allows adding recycled PP raw materials within 45% to lower clients' production cost significantly.
Panels produced by this line own outstanding comprehensive physical features benefiting from regular hexagonal honeycomb inner structure: ultra-light weight yet high compressive strength, excellent shock absorption, waterproof, anti-corrosion and sound insulation performance, fully recyclable without harmful additives, far exceeding paper honeycomb's moisture defect and aluminum honeycomb's high-cost shortcoming. Thanks to diversified superior properties, finished PP honeycomb composite boards have wide cross-industry application ranges. In logistics packaging field, they are made into reusable turnover pallets and protective packing boxes replacing wooden and corrugated cartons; for automotive manufacturing, they serve as vehicle inner partition, carriage lining and RV interior decorative panels; in construction industry, they work as lightweight partition wall boards, ceiling substrates and temporary engineering plates; meanwhile they are popular for exhibition display stands, furniture core boards and marine lightweight structural accessories across global markets.
As a professional plastic extrusion machinery manufacturer based in Qingdao, Zhongsu Machinery provides personalized mold modification, installation guidance and lifelong after-sales maintenance for every overseas buyer of honeycomb production line. Our mature six single-screw co-extrusion technology has passed repeated on-site running verification from customers in Southeast Asia, Middle East and Eastern Europe, becoming mainstream preferred production equipment for medium and large-scale PP honeycomb board factories globally.
