About China Ningbo Rhong Machinery Manufacturing Co., Ltd - Plastic Processing Machinery Supplier in China

China, specifically the Ningbo region, lists five active products in its catalogue. The company focuses on equipment for plastic processing and industrial vacuum cleaning, covering both plastic processing machinery and industrial vacuum cleaners. Its product list includes a middle‑speed machine attachment granulator, a powerful granulator, water‑type and oil‑type mold temperature controllers, and a separate vacuum conveyor driven by a single‑phase motor. The catalogue aligns with HS code families for plastic processing equipment (typically 8479) and vacuum handling machines (often 8422). The supplier is classified as an imported, harbor‑trust tier, indicating established trade reliability within Chinese export channels.

The five items reflect core functions in injection‑moulding lines and post‑processing loops. Granulators reduce polymer pellets to uniform size, while mold temperature controllers maintain precise thermal conditions for both water‑cooled and oil‑cooled moulds. The vacuum conveyor provides material handling for debris removal in clean‑room or industrial environments. No additional product categories are listed, and the supplier does not disclose certifications in the supplied data.

Product Range and Specialties of China Ningbo Rhong Machinery Manufacturing Co., Ltd

The catalogue features two granulators, two mould‑temperature controllers, and a vacuum conveyor. In the plastic processing sector, granulators are typically rated by feed capacity (e.g., 0.5‑2 t/h), screen size (0.5‑5 mm), and motor power (5‑30 kW). Buyers often look for stainless‑steel wear plates and interchangeable screens to handle various polymer grades. Mold temperature controllers are classified by temperature range (0‑200 °C for water, 0‑250 °C for oil), control accuracy (±0.5 °C), and flow rate (10‑30 L/min). Vacuum conveyors used in industrial cleaning usually specify suction power (2‑5 kW), motor voltage (220‑380 V), and filter efficiency (HEPA or ULPA).

Industry standards such as IEC 60204‑1 for electrical safety and ISO 12100 for machinery safety are commonly applied to these equipment types. Plastic processing machinery often complies with CE marking requirements for European markets, while Chinese exporters may also hold CNCA certification for certain categories. Buyers typically request material data sheets, performance curves, and compliance certificates when evaluating these machines.

Trade and Export Information - China Ningbo Rhong Machinery Manufacturing Co., Ltd

China remains a major exporter of plastic processing machinery, with the majority of shipments destined for Southeast Asia, Europe, and North America. HS chapter 84 (machinery) and chapter 85 (electrical equipment) cover the granulators and temperature controllers, while vacuum conveyors fall under HS 8422 for cleaning machines. Import regulations commonly require CE conformity for European buyers and UL listing for North American customers. Shipping is usually arranged in 20‑ft or 40‑ft containers, with standard palletisation (1.2 m × 1.0 m pallets) and protective wood crating to prevent damage.

Exporters from China often provide pre‑inspection reports through agencies such as SGS or Bureau Veritas, especially for machinery subject to ISO 9001 quality management audits. Typical Incoterms include FOB Ningbo or CIF destination port, with buyers arranging customs clearance and any required type‑approval testing in the import market.

Sourcing from China Ningbo Rhong Machinery Manufacturing Co., Ltd - Buyer Guidance

When sourcing granulators, request the machine’s capacity chart, screen mesh specifications, and a CE Declaration of Conformity. Verify that the motor power matches the intended production volume and that wear parts are made of hardened steel or corrosion‑resistant alloys.

For mold temperature controllers, ask for temperature stability data, control loop diagrams, and compliance documents such as CE or UL certificates. Confirm the coolant type (water or oil) aligns with your plant’s infrastructure and that the controller includes safety interlocks.

The vacuum conveyor should be evaluated for suction capacity, filter class, and electrical rating. Request a performance test report and, if possible, a video of the unit operating under load. Ensure the supplied motor rating matches the voltage and frequency of your facility.

What granulator models are listed in the catalogue?

The catalogue includes a middle‑speed machine attachment granulator and a powerful granulator, both designed for polymer size reduction in injection‑moulding lines.

What are the key specifications of the water‑type mold temperature controller?

It regulates water‑based coolant temperatures typically between 0 °C and 200 °C with an accuracy of ±0.5 °C, and is equipped with flow control suitable for standard mould cooling circuits.

What differentiates the oil‑type mold temperature controller from the water‑type version?

The oil‑type controller handles higher temperature ranges up to about 250 °C, using oil as the heat‑transfer medium, which is common for high‑temperature mould applications.

What power source does the vacuum conveyor use?

The vacuum conveyor is driven by a single‑phase motor, usually rated between 2 kW and 5 kW, compatible with standard 220‑380 V industrial electricity supplies.

Which HS codes are typically applied to these machines for customs clearance?

Granulators and temperature controllers fall under HS 8479 (other machines) or HS 8501 (electric motors), while the vacuum conveyor is classified under HS 8422 (vacuum cleaners and cleaning machines).

What certifications should a buyer request before purchasing?

Buyers should request CE or UL certificates for electrical safety, an ISO 9001 quality management audit report, and any applicable type‑approval documents required by the destination country.

What are typical packaging and shipping methods for this equipment?

Machines are usually packed on wooden pallets with shrink‑wrap, loaded into 20‑ft or 40‑ft containers, and shipped under FOB Ningbo or CIF terms, depending on the buyer’s preference.

What is the usual lead time for ordering these machines?

Lead times commonly range from 30 to 60 days after receipt of a confirmed purchase order, depending on configuration, tooling, and any required certification documentation.
