Import 55/110 Cincinnati Conical Twin Screw And Barrel — Buy in wholesale FOB from Supplier in China

The 55/110 Cincinnati conical twin screw and barrel is a precision-matched extrusion component set manufactured by Zhejiang Jinteng Machinery Manufacture Co., Ltd. in Zhoushan, Zhejiang Province, China. The designation 55/110 refers to the nominal screw diameter in millimetres and the barrel bore diameter, a standard sizing convention for Cincinnati-style conical twin-screw extruders used in PVC profile, pipe and compounding applications. The supplier specifies alloy hardness of HRC 50-65, achieved through centrifugal casting with tungsten carbide infiltration, a process that yields a dense, carbide-rich inner surface bonded to a tougher outer steel shell.

Centrifugal casting distributes tungsten carbide particles uniformly against the bore surface under high rotational force, producing gradient hardness that resists abrasive wear from mineral-filled PVC compounds and calcium carbonate masterbatches typical in conical twin-screw service. The conical geometry, with converging screw diameters from feed to discharge, generates high compression ratios (typically 3:1 to 4:1) and self-wiping action that improves mixing efficiency and reduces residence time for heat-sensitive formulations. Standard material for such barrels is 38CrMoAlA nitriding steel or bimetallic equivalents, with screw substrates in 40Cr or W6Mo5Cr4V2 high-speed tool steel depending on wear severity and output requirements.

This component set suits replacement and retrofit programmes for Cincinnati Milacron, Weier, Bausano and OEM-compatible conical twin-screw extruders in the 45-65 mm screw range. Typical buyers include PVC pipe manufacturers, window profile extruders, WPC (wood-plastic composite) processors and recycling compounders seeking to restore original clearance specifications or upgrade from nitrided to carbide-lined barrels. The supplier lists additional standard sizes from 15/30 through 105/203, indicating pattern coverage across laboratory to production-scale machines. Buyers should confirm centre distance, keyway configuration, heating band placement and thermocouple port threading against their existing barrel housing before ordering.

Zhejiang Jinteng Machinery Manufacture Co., Ltd. is located at No.14 Ligang North Road, Jintang, Dinghai, Zhoushan 316000, Zhejiang Province, China, placing it within the Zhoushan precision machinery manufacturing cluster, a region with established supply chains for extrusion and injection moulding components. The supplier holds an imported-tier classification on the marketplace, with a harbour trust designation. The response rate is recorded at 0.00% with zero average response hours, indicating no inquiry response data is currently available through the platform. The company profile does not disclose founding year, employee count, annual revenue, specific certifications, or named clientele.

The listing focuses exclusively on conical twin screw and barrel sets for Cincinnati-compatible extruders, with a catalogue spanning sixteen standard size combinations from laboratory 15/30 units to large production 105/203 assemblies. The supplier emphasises tungsten carbide centrifugal casting as a core competence, alongside conventional nitrided alternatives implied by the size range. No information is provided about in-house machining capabilities, quality control protocols, export licence status, or after-sales technical support. Buyers should verify these operational details directly with the supplier, along with confirmation of whether the 55/110 set is held in inventory or produced to order.
