From Steel Wire to Sturdy Chicken Cages: A Complete Guide to Gantry Welding Machine Production

This article will take you inside the production workshop, detailing the complete process of manufacturing chicken cages with a gantry welding machine, and reveal the core advantages it brings to your business.

Part 1: The 4 Key Steps of Manufacturing Chicken Cages with a Gantry Welder

Gantry welders are typically used to produce welded mesh products. For chicken cages, the main applications are cage body meshes (front, back, bottom, top nets) and cage doors.

Step 1: Raw Material Preparation & Straightening

Cold-drawn steel wires (depending on cage load requirements, typically 2.5mm – 4.0mm in diameter) are fed from decoilers. The machine's built-in straightening modules straighten the coiled wires to ensure a flat and non-warped welded mesh.

Step 2: Automatic Wire Arrangement & Positioning

• Longitudinal wires (warp wires): The machine automatically arranges the long wires neatly at a set spacing (e.g., 5cm or 10cm).

• Transverse wires (weft wires): The cross wires are precisely fed across the longitudinal wires via a feeding mechanism.
  A major feature of the gantry welder is its gantry-style beam, which spans the entire working width, ensuring that dozens or even hundreds of welding electrodes contact the cross points simultaneously.

Step 3: Servo Control + Pressure Welding

This is the most critical step:

1. Servo motor drive: The gantry moves into position, precisely aligning each intersection point.

2. Pressure & Current Application: The upper and lower electrodes apply pressure to the intersection of the steel wires while instantly passing a high current. Resistance heat melts the crossing points.

3. Forging & Forming: After the current is cut off, the electrodes maintain pressure to forge the nugget, forming a flat plum blossom weld point.

The entire process takes only 0.02 – 0.5 seconds. Hundreds of weld points on a single mesh are completed in one go.

Step 4: Cutting to Length & Bending

The completed large mesh is cut into individual cage panel sizes by a shearing device. Then, using bending equipment (or manual assistance), the flat mesh is bent into U-shaped bottom nets, L-shaped back nets, and finally assembled into complete 3D cage units using clips.

Part 2: 5 Overwhelming Advantages of Gantry Welding Machines Compared to Traditional Methods

1. Extremely Strong Weld Points: No False Welds or Missed Welds

• Traditional spot welding: Relies on manual movement of weld guns. Fatigue easily leads to misaligned or weak welds. Cages fall apart quickly.

• Gantry Welder: Uses synchronized welding control. Current and timing parameters are consistent for every weld point. Welds are flat and have strong tensile strength (reaching over 70% of the wire's tensile strength). They resist corrosion from humid manure environments.

2. Exponential Improvement in Production Efficiency

• One gantry welder can complete 10–20 cage meshes per minute.

• Comparison: A skilled manual welder can only weld dozens of small cage doors per day. A gantry welder can produce hundreds of complete cages per day. Labor costs are reduced by 80%, while production capacity increases by over 500%.

3. Extreme Flatness: Perfect for Automated Stacked Farming

Modern stacked poultry cages require absolute flatness. Otherwise, they won't stack accurately (causing jams in automatic manure removal belts or feeding carts). The gantry welder's overall compression welding method ensures extremely low flatness deviation, making it perfectly compatible with automated farming systems.

4. Material Savings & Cost Reduction

• No filler material required: Gantry welders use resistance heat from the steel wire itself. No welding rods or filler wires are needed, reducing consumable costs.

• Less scrap: CNC-controlled wire feeding ensures precise material usage, saving 3%–5% of steel compared to manual cutting.

5. High Flexibility & Quick Tooling Changeover

Modern CNC gantry welders support one-click recall of process parameters. By simply changing the electrode tooling, the same machine can weld 2.5mm fine mesh for layer cages or 3.5mm reinforced mesh for broiler cages. Changeover time is less than 30 minutes.

Part 3: 3 Buying Tips for Choosing a Gantry Welder for Chicken Cage Manufacturing

If your workshop or factory is considering upgrading equipment, pay attention to these technical specifications:

1. Welding Width: Based on your cage height (e.g., 40cm for layer cage fronts, 45cm for broiler cage fronts), choose an effective welding width of 1.2m or 1.5m.

2. Electrode Material: Choose Chromium Zirconium Copper (CuCrZr) electrodes. They are heat-resistant and resistant to deformation, capable of over 100,000 consecutive welds.

3. Cooling System: A forced water cooling circulation system is mandatory. Without proper cooling, the transformer and electrode tips will burn out quickly.
