Import Black Masterbatc Extruder Pelletizing Line — Buy in Bulk from Supplier in China

Nanjing GS-Plus Machinery Manufacturing Co., Ltd. produces a black masterbatch extruder pelletizing line for compounding carbon black concentrates into polymer pellets. The system is designed for continuous operation in packaging, automotive, and consumer goods sectors where uniform pigment distribution and additive incorporation are critical. The supplier describes high-output configuration, precision temperature control, and mixing systems for consistent batch quality, plus a user-adjustable control interface for parameter monitoring. The listing originates from Jiangning District, Nanjing, Jiangsu Province, China, with the supplier holding harbor trust tier status.

Extruder pelletizing lines for masterbatch production typically employ co-rotating twin-screw extruders for intensive dispersive and distributive mixing, with screw diameters ranging from 36 mm to 133 mm and motor ratings from 45 kW to 500 kW depending on throughput target. Standard line configurations include volumetric or gravimetric feeder systems for carbon black and additives, a melt pump for stable die pressure, water bath or air-cooling pelletising with rotary cutter, and vibratory classifier for fines removal. Typical outputs for black masterbatch range from 200 kg/h for laboratory-scale units to 2,000 kg/h or more for industrial installations. Die face pelletising (underwater or water ring) is common for black formulations to minimise dust and improve pellet shape consistency, with typical pellet dimensions of 3-4 mm diameter by 3-5 mm length.

This equipment targets masterbatch compounders, polymer modification plants, and large plastics processors seeking in-house colour compounding capability. Buyers include packaging film producers requiring consistent let-down ratios, automotive tier suppliers needing UV-stabilised black compounds, and recycling operations upgrading reclaimed polymer with carbon black for property restoration. The supplier mentions customisable configurations, suggesting modular screw design, barrel heating zones, and downstream equipment options. Import considerations include confirming electrical standards (380V/50Hz typical for China, versus 480V/60Hz for North America), compliance with destination country machinery directives, and availability of spare screws, barrels, and wear parts from the supplier or designated agents.

Nanjing GS-Plus Machinery Manufacturing Co., Ltd. is located in Jiangning District, Nanjing, Jiangsu Province, China, a region with established plastics machinery manufacturing clusters. The supplier holds harbor trust tier status on trust tier. The response rate is recorded as 0.00% with zero average response hours, indicating no platform-mediated inquiry activity. The company profile does not disclose founding year, employee count, annual revenue, export markets, or installed machine base. No certifications, patents, or industry memberships are listed in the source material. Buyers should verify business licence, manufacturing scope, and export qualification through direct enquiry and, where possible, factory audit or video inspection.

The supplier's product description emphasises customisable solutions and flexible configurations, suggesting made-to-order production rather than extensive finished inventory. The mention of ISO and CE certification in the source text should be treated as unverified until certificates with scope, issuing body, and validity dates are provided directly by the supplier. The company address in Jiangning District places it within Nanjing's industrial zone, with access to Shanghai Port (approximately 300 km) for international shipment. Buyers should confirm whether Nanjing GS-Plus has prior export experience to their region, including familiarity with voltage standards, safety regulations, and import documentation requirements.
