Buy & Import Co-rotating twin-screw extruder from Nanjing Kaiyou Rubber & Plastic Machinery Co., Ltd - Wholesale Supply

The co-rotating twin-screw extruder from Nanjing Kaiyou Rubber & Plastic Machinery Co., Ltd is available in three models: HKY-35, HKY-50, and HKY-65, with screw diameters of 35.6mm, 50.5mm, and 62.4mm respectively. Each model features a modular barrel system with L/D ratios from 32:1 to 56:1, and operates at a maximum screw speed of 600rpm. The extruders are driven by gearboxes designed for high torque output, supporting outputs from 5kg/h to 300kg/h depending on model and material.

The extruder uses a building block principle, allowing screw and barrel configurations to be swapped for different processing tasks such as devolatilization, reactive extrusion, or polymer blending. The gearbox is a new design with improved torque density, enabling high output at 600rpm without overheating. The system is compatible with engineering polymers, glass fiber reinforcement, masterbatches, and powder coatings. The PLC control system allows for programmable temperature and speed profiles.

This equipment is used by compounders producing specialty plastics, cable materials, and functional granules. Buyers typically require consistent melt temperature control and low shear degradation. The extruders are shipped fully assembled or in major subassemblies. Installation requires a 380V 50Hz power supply, compressed air, and a vibration-isolated foundation. Buyers should confirm whether the unit includes auxiliary devices such as pelletizers or feeders.

Sourcing Co-rotating twin-screw extruder from Nanjing Kaiyou Rubber & Plastic Machinery Co., Ltd - China Import Guide

Before placing an order, verify the exact model number and configuration of the extruder, especially the screw profile and barrel length. Request the PLC software version and a sample of the control interface. Confirm whether the ISO 9001 certificate is current and issued by an accredited body. Ask for a video of the machine running with a standard compound under load.

Logistics are typically shipped FOB Nanjing or CIF destination port. Lead time is generally 8 to 12 weeks, depending on customization. Payment terms are commonly 30% advance, 70% against bill of lading. Incoterms should be clearly defined. The machine is usually packed in wooden crates with desiccant and anti-rust coating. Confirm if installation tools and spare parts are included.

Quality inspection should include a 2-hour dry run at 50% speed and a 4-hour wet run with your target compound. Request the final inspection report with torque readings, temperature stability logs, and vibration measurements. Documentation must include a material certificate for all wetted parts, a PLC program backup, and an English operation manual. Insist on a signed performance acceptance document before final payment.
