New Expansion of Light Expanded Metal Mesh Applications in Electric Fly Swatters

With global temperatures rising, flies and mosquitoes multiply rapidly every summer and survive longer than ever. This drives the wide popularity of electric fly swatters. Though a simple household pest control product, electric bug zapper rackets efficiently eliminate mosquitoes and flies indoors.

Electric fly swatters are assembled with light expanded metal mesh and plastic frames, adopting a classic three-layer mesh structure: two outer protective expanded metal layers plus one inner conductive electrode layer.

· Outer expanded metal mesh: Galvanized steel or stainless steel material, mesh opening 7mm–12mm, sheet thickness 0.5mm–1.2mm

· Inner conductive expanded metal mesh: Mesh opening 2mm–5mm, sheet thickness 0.3mm–0.5mm, fully flattened surface to prevent hand cuts during daily use

1. Core Functional Applications

1.1 High-Voltage Conductive Electrode (Middle Inner Mesh)

Integrated one-piece expanded metal mesh forms uninterrupted conductive paths with low resistivity and evenly distributed electric field. Its 2mm–5mm diamond apertures trap flies and mosquitoes easily. Once insects bridge the positive and negative mesh layers to form a circuit, instant high-voltage electric arcs kill flying pests immediately. Free of welding joints, the mesh resists wire breakage after repeated swatting and maintains consistent conductive performance.

1.2 Outer Safety Protective Mesh (Front & Rear Guard Layers)

The ultra-light integrated expanded metal structure boasts outstanding rigidity and stays deformation-free under frequent swatting and collision. Specially sized mesh openings block fingers from touching the high-voltage inner layer to eliminate electric shock risks. Lightweight mesh greatly cuts down the overall weight of the bug zapper racket for effortless waving, while low air resistance prevents flying insects from escaping during swatting.

1.3 Structural Support & Lightweight Design

Compared with woven wire mesh, stretched light expanded metal mesh features lighter weight and superior structural integrity without extra border reinforcement. Thin base sheets reduce raw material consumption and lower finished product costs. Galvanized or stainless steel surface treatment delivers excellent moisture-proof and anti-rust performance, avoiding oxidation and electric leakage in damp kitchen and bathroom environments. The smooth flattened surface is easy to wipe clean for low-maintenance daily use.

2. Material & Processing Advantages for Electric Fly Swatter Production

1. Raw Material: 0.3–1.2mm thin low-carbon galvanized steel sheet and stainless steel sheet balance reliable conductivity, lightweight texture and long-term rust resistance.

2. Structural Superiority: One-time stretch forming eliminates loose metal strands. The mesh resists edge warping and wire shedding after long-term frequent use, with a longer service life than traditional woven wire mesh.

3. Mass Production Compatibility: Whole-sheet cutting and forming simplify processing steps, perfectly matching automated assembly lines for large-volume electric fly swatter manufacturing.

3. Application Summary

Featuring lightweight build, high structural strength, uniform electric conduction, reliable safety protection, low cost and easy processing, light expanded metal mesh serves as the dedicated three-layer mesh substrate for electric fly swatters. It fulfills three core design demands simultaneously: efficient high-voltage insect elimination, human anti-electric shock safety and lightweight finished racket construction, making it the mainstream mesh material for civilian bug zapper rackets worldwide.
