Electrical Panels

Precision Mekotek Fiber Laser Power in Electrical Panel Manufacturing

From power distribution to automation systems, electrical panels—which serve as the nervous system of industry—must protect the expensive and critical equipment inside them (circuit breakers, drives, PLCs) from external factors. This protection (IP standards) is only possible with flawless sheet metal work. A misaligned cover prevents the sealing gasket (cast polyurethane gasket) from functioning properly and causes water and dust to enter the panel.

At Mekotek Lazer, we offer solutions to the two biggest challenges faced by panel manufacturers: cutting galvanized sheet metal at high speeds without compromising its corrosion resistance, and punching thousands of ventilation holes (slots) in a matter of seconds. We free you from the die costs and noise of traditional punch presses, adding quiet power to your production.

Why Choose Mekotek Fiber Lasers for Panel Production?

Panel manufacturing is a high-volume, detail-intensive process. Mekotek Fiber Laser Cutting Machines are built with the structural robustness and smart technologies needed to handle this pace.

1. Flawless “Rust-Free” Cutting of Galvanized Sheet Metal

The primary material used in the panel industry is galvanized sheet metal. Standard lasers burn through the zinc coating when cutting galvanized sheet metal, creating a risk of darkening or rusting along the edges. Mekotek’s high-pressure nitrogen or dry air cutting technology creates a “cold cut” effect by preserving the zinc coating. The cut edges remain corrosion-resistant and do not require additional cleaning before painting.

2. “Fly-Cut” Speed in Ventilation Holes

Drilling the thousands of vent holes (ventilation slots) needed to prevent panels from overheating takes minutes using traditional methods. Mekotek’s “Fly-Cut” technology drills these holes in a scanning pattern by simply turning the laser beam on and off, without ever stopping the laser head. Your production time is reduced by 50% to 70%.

3. Micron-Level Precision for IP Standards

Protection ratings such as IP54 and IP65 require a perfect fit between the cover and the housing. Mekotek’s cutting accuracy of ±0.03 mm ensures that the parts align perfectly after bending. The sealing gaskets press firmly against the surface, allowing your panel to pass the tests successfully.

Industry Applications: From Distribution to Automation

Mekotek technology plays an active role in every stage of low- and medium-voltage panel production:

Freestanding and Wall-Mounted Panels

Modular panel bodies, covers, and mounting plates. When processing large-format sheet metal (e.g., 1500×3000 mm), our automatic loading systems (Tower) enable unmanned, waste-free production.

Piano Types and Control Consoles

Holes for buttons, screens, and indicators on operator panels. Circular, square, or custom-shaped holes are cut exactly to the dimensions specified in the drawing, without the hassle of changing dies. The buttons fit snugly into their sockets.

Copper Busbar Processing

Cutting the copper busbars that carry electrical power within the panel. Mekotek Fiber Lasers can cut not only steel but also conductive metals such as copper and aluminum with high precision. The holes for busbar bending and assembly are cut with the laser in a single pass.

Outdoor Pavilions and Cabins

Transformer enclosures and field panels manufactured from thick galvanized or stainless steel sheet metal, designed to withstand outdoor conditions. Mekotek’s thick-sheet-cutting capability accelerates the production of these robust structures.

How Do We Help You Grow Your Business?

Competition in the panel industry centers on delivery time and quality. Mekotek Lazer offers you the following advantages:

Eliminate Punch Die Costs

For each different button diameter or fan hole, you need to purchase a new die for the punch press. With a laser cutter, however, the only limit is your imagination. Even if your customer says, “I don’t want a square hole—I want a star-shaped one,” you can simply modify the design and cut it in just one minute.

No More Additional Machinery for Copper Bars

A separate drilling/cutting machine is typically used for copper bars. With the Mekotek Fiber Laser, you can process your copper bars on the same machine you use to cut sheet metal, thereby reducing your machine investment costs.

Cost Savings in Assembly Work

Laser-drilled screw holes and assembly guides are so precise that your assembly line personnel won’t have to waste time searching for parts or aligning holes. Your production line runs smoothly.

Technical Insights: Flexible Manufacturing and Nesting

In panel manufacturing, the components of a panel (body, cover, base, and cap) can often vary in thickness.
