Qingdao Qinghang Plastic Machinery Co., Ltd. specializes in manufacturing professional plastic PP (Polypropylene) sheet production lines. Polypropylene extrusion sheets are manufactured through a precise sequence of blending, extrusion, calendering, cooling, and cutting processes, incorporating various functional additives based on specific engineering requirements.
Our heavy-duty PP sheet extrusion plant is a fully integrated, closed-loop pipeline system engineered to realize total automation from raw material infeed to the finished stacked sheet:
Infeed & Blending System: Equipped with an industrial raw material mixer (blender) and a screw-type automatic feeding system for consistent, dustless material loading.
Vented Single-Screw Extruder: Features a high-efficiency vented single-screw extruder designed to eliminate moisture and volatiles, ensuring optimal melt density and structural integrity.
Premium Electrical Components: The entire system integrates premium global electronics, utilizing Omron temperature controllers for precise thermal zoning and Siemens contractors for rugged electrical reliability.
Coat-Hanger Extrusion Die/Mold: Utilizes an advanced coat-hanger distribution channel die to guarantee exceptionally uniform polymer flow, precise thickness tolerances, and stable output.
Three-Roller Calendering Machine: Driven by a dedicated, high-precision three-roller reduction gearbox. Roller temperatures are regulated via an integrated mold temperature controller, allowing effortless adjustments to achieve an ultra-smooth, bright, and flat sheet surface.
Downstream Integration: Equipped with a cooling bracket featuring built-in edge-trimming and slitting knives, a heavy-duty haul-off (traction) unit integrated with a protective film laminating device, a high-precision transverse (horizontal) cutting machine, and an automatic unloading stacker.
(Note: All production specifications, technical configurations, and extruder dimensions can be fully customized based on specific client requirements.)
Our advanced machinery accommodates a versatile production matrix, capable of meeting strict international standards:
Extrusion Thickness Range: 3-40mm for heavy-duty sheets)
Sheet Width Range: 500mm - 3000mm
Highly Recommended Commercial Specifications: Thickness of 3mm - 30mm | Width of 1500mm - 300mm
Pure Polypropylene (PP) sheets extruded by our machinery offer exceptional material performance, making them the preferred engineering plastic for global eco-friendly industries:
Low Density & Lightweight: Reduces structural weight while maintaining high rigidity.
Superior Machineability: Highly weldable, easy to thermoform, cut, and fabricate.
Excellent Engineering Resistance: Outstanding chemical resistance against acids/alkalis, superior thermal stability, and high impact resistance.
100% Eco-Friendly: Non-toxic, odorless, and fully compliant with international environmental engineering regulations.
The industrial-grade thick sheets produced by our extrusion line are widely used across global anti-corrosion, chemical, and water-treatment infrastructure networks:
Acid and Alkali Resistant Equipment: Chemical storage tanks, pickling lines, and lining plates.
Environmental Protection Infrastructure: Scrubbing towers, mist eliminators, exhaust gas towers, scrubbing/degassing columns, electroplating baths, and mixing towers.
Waste Management Systems: Industrial wastewater and waste gas emission treatment equipment, and heavy-duty dust-free towers.
Surface Treatment & Storage: Industrial spray booths, automated coating lines, and heavy-duty plastic water reservoirs/tanks.
