Leno circular loom

When selecting a Leno Circular Loom, you must prioritize the number of shuttles (typically 4, 6, or 8) and the weaving width, which usually ranges from 800mm to 1200mm. Ensure the machine features an automatic stop system for warp/weft breakage and a frequency conversion speed control to maintain production stability. High-quality looms should support a maximum folding width that aligns with your specific bag production requirements.

For cross-border procurement, the equipment must carry the CE Marking to meet European safety standards or UL certification for the North American market. Additionally, verify that the manufacturer is ISO 9001 certified to ensure consistent quality management. Compliance with IEC 60204-1 for electrical safety of machinery is also a critical benchmark for industrial-grade looms.

The Leno weave (mesh weave) technology uses two warp threads twisted around the weft threads to create a stable, non-slip mesh structure. This is specifically designed for producing breathable packaging for agricultural products like onions, potatoes, and citrus. Unlike standard flat-weave looms, Leno looms must have specialized leno-motion attachments to ensure the mesh openings remain uniform under tension.

To maximize the lifespan of the loom, implement a daily lubrication schedule for the cam and shuttle tracks. The shuttle nylon rollers and heald wires are high-wear parts that should be inspected weekly. It is recommended to choose suppliers who provide a one-year warranty and a spare parts kit (including springs, sensors, and cutters) with the initial purchase to minimize downtime.

Always mandate a Pre-Shipment Inspection (PSI) conducted by a third-party agency like SGS or Intertek. Request a video running test of the specific machine serial number you are purchasing, showing it operating at full speed for at least 30 minutes. For secure transactions, utilize the secured payment services on Made-in-China.com to ensure funds are only released upon proof of shipment.

Focus negotiations on the Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for extended technical support (e.g., 24/7 remote video assistance) and the inclusion of installation and commissioning services. If purchasing multiple units, aim for a 5-10% volume discount or request the supplier to include two years' worth of wear-and-tear spare parts at no extra cost.

Due to the size and weight, these machines must be shipped via FCL (Full Container Load). Ensure the contract specifies vacuum packaging and anti-rust coating for all precision metal components to prevent sea-salt corrosion. Confirm the Incoterms clearly (e.g., CIF or FOB); for heavy machinery, FOB is often preferred by experienced buyers to maintain control over the shipping line and local handling fees.

Verify the HS Code (typically 8446.21 for circular looms) with your local customs broker to determine applicable import duties and VAT. Ensure the supplier provides a detailed Packing List, Commercial Invoice, and Certificate of Origin to benefit from any existing Free Trade Agreements (FTA) between your country and China.
