Used fishing net machine manufacturers

When sourcing a used fishing net machine, the mechanical integrity is paramount. You must verify the condition of the cam and link mechanism, as these are the heart of the knitting process. Check for excessive play in the needle bar and ensure the shuttles or hooks show no signs of deep scoring or rust. It is highly recommended to request a video of the machine running at full speed to listen for abnormal vibrations or grinding noises that indicate bearing failure.

Buyers must align the machine's capabilities with their production needs. Specifically, confirm the Pitch (knot distance), the number of shuttles, and the working width. Ensure the machine is compatible with the twine materials you intend to use, such as Nylon monofilament, multifilament, or PE. Additionally, verify the voltage and frequency (e.g., 380V/50Hz) to ensure it matches your local industrial power grid without requiring expensive transformers.

Japanese brands like Toyo (TNS series) and Amita are industry benchmarks for durability and precision, often retaining high resale value. Chinese brands such as Yangzhou Mengcheng or Huitong offer excellent cost-efficiency and easier access to replacement parts. For used equipment, prioritize models that have high parts interchangeability to avoid downtime when components eventually wear out.

Even for used equipment, safety cannot be compromised. Ensure the machine has functional emergency stop buttons and protective guarding over moving parts. If importing to the EU, check for CE marking; for the US, ensure electrical components meet UL or NEMA standards. Requesting an original maintenance log can serve as proof that the machine has been serviced according to safety protocols.

The most effective strategy is to hire a third-party inspection agency (such as SGS or BV) to conduct a pre-shipment inspection. They can verify the serial number, perform a load test, and document the physical condition. Never rely solely on static photos; always insist on a live video demonstration of the machine knotting a net.

Focus your negotiation on the refurbishment scope. Instead of just pushing for a lower price, negotiate for the inclusion of wear-and-tear spare parts (like needles, springs, and shuttles) in the final price. Ask the supplier to provide a 6-month 'major parts' warranty, which demonstrates their confidence in the machine's refurbished state.

Heavy machinery is prone to corrosion during sea transit. Insist on vacuum packaging with desiccant bags and a heavy-duty wooden crate (IPPC certified). The machine must be bolted to the base of the crate to prevent shifting. For used items, ensure the supplier applies a rust-inhibitor coating on all exposed metal surfaces before packing.

Use secure payment methods such as Letters of Credit (L/C) or trade assurance services provided by reputable platforms like Made-in-China.com. Avoid 100% upfront payments; a standard structure is 30% deposit and 70% balance after inspection but before shipment. This ensures the supplier remains accountable for the machine's quality until it leaves the factory.
