About The Ruian Sanlin Trade Machinery - Industrial Machinery Supplier in China

China‑based The Ruian Sanlin Trade Machinery lists five active products in its catalogue. The company’s portfolio spans Industrial Machinery, PP (Polypropylene) Woven Bags, Shoe Accessories, Medical Face Masks and Building Construction Machineries and Equipments, reflecting a focus on equipment for textile and personal protective equipment production.

The catalogue includes a Non‑woven Mask Three Output Line, a PE Plastic Shoe Cover Machine, a Shower Cap Machine, a Fully Auto Outside Mask Making Machine and a Cover‑Manufacturing Machine identified with HS code 8477.80. The Cover‑Manufacturing Machine is described as having a steel housing with ultrasonic transducer components, indicating a metal‑based construction suitable for high‑precision manufacturing.

Product Range and Specialties of The Ruian Sanlin Trade Machinery

The listed machines cover three main production lines: mask making, shoe cover fabrication and shower cap assembly. Mask lines typically operate at speeds of 20,000‑40,000 pieces per hour, use melt‑blown non‑woven fabrics, and require precise ultrasonic sealing to meet ASTM F2100 or EN 14683 standards. Shoe cover machines usually handle PP or PE films, offering adjustable width settings and cut‑length controls for custom packaging. Shower cap machines are designed for thin polymer sheets, often featuring heated sealing rollers to achieve water‑tight seams.

In the broader industrial machinery sector, HS chapter 84 (particularly 8477.80) covers machines for working rubber or plastics, and buyers commonly request compliance with ISO 9001 quality management and CE marking for safety. For mask and PPE equipment, ISO 13485 for medical device manufacturing is frequently required. Typical material specifications include steel frames with corrosion‑resistant coatings, ultrasonic transducers operating at 20‑40 kHz, and control panels supporting PLC programming.

Trade and Export Information - The Ruian Sanlin Trade Machinery

China remains one of the largest exporters of mask‑making and PPE equipment, supplying Europe, North America and Southeast Asian markets. Buyers of such machinery usually import under HS 8477.80 and related codes, with freight commonly arranged in 20‑ft or 40‑ft containers on FOB Shanghai or CIF terms. Export documentation often includes a commercial invoice, packing list, certificate of origin and, where applicable, CE Declaration of Conformity.

Industry practice calls for verification of ISO 9001 or ISO 13485 certification, test reports demonstrating ultrasonic seal strength (typically >5 N/mm), and compliance with local medical device regulations. Packaging for the steel‑housing machines generally involves wooden crates with internal cushioning, and moisture‑resistant pallets are used for sea freight to protect electronic components.

Sourcing from The Ruian Sanlin Trade Machinery - Buyer Guidance

When sourcing from this supplier, request detailed machine specifications such as power consumption (kW), production capacity (units per hour), and the type of control system (PLC or HMI). Ask for copies of any ISO or CE certificates, ultrasonic transducer performance data, and a recent factory audit report to confirm build quality. Arrange a pre‑shipment inspection that checks dimensions, weight, and functional testing of the sealing system before loading.

Typical buyers also request a sample run using the intended non‑woven or polymer material to verify that the machine meets mask‑grade or shoe‑cover‑grade performance criteria. Verify the warranty period, spare‑part availability and the lead time, which for comparable Chinese equipment ranges from 45 to 90 days after order confirmation.

What types of machines are included in the product catalogue?

The catalogue lists a Non‑woven Mask Three Output Line, a PE Plastic Shoe Cover Machine, a Shower Cap Machine, a Fully Auto Outside Mask Making Machine and a Cover‑Manufacturing Machine (HS 8477.80) with a steel housing and ultrasonic transducer.

Which HS code applies to the Cover‑Manufacturing Machine?

The Cover‑Manufacturing Machine is classified under HS code 8477.80, which covers machines for working rubber or plastics.

What certifications should a buyer request for these machines?

Buyers should request ISO 9001 for general quality management, ISO 13485 if the machine will be used for medical‑grade mask production, and a CE Declaration of Conformity where applicable.

What is a typical production capacity for the mask making line?

Mask making lines of this type commonly produce between 20,000 and 40,000 masks per hour, depending on material feed speed and seal settings.

What packaging is used for shipping the steel‑housing machine?

The machine is usually packed in a reinforced wooden crate with internal foam cushioning, placed on a moisture‑resistant pallet for sea freight.

What are common payment and shipping terms for Chinese machinery exporters?

Exporters often work on FOB Shanghai or CIF destination, with payment terms such as T/T 30 % deposit and 70 % balance before shipment.

How can a buyer verify the ultrasonic sealing quality?

Request a test report showing ultrasonic seal strength, typically measured in newtons per millimetre, with a minimum of 5 N/mm for mask and shoe cover applications.

What is the usual lead time for these machines?

Lead times for comparable equipment from Chinese manufacturers range from 45 to 90 days after order confirmation, depending on configuration and optional accessories.
