In architecture, perforated metals are often used as decorative accents. Additionally, industries such as food and beverage, chemicals, energy, and acoustics utilize perforated metals for practical applications like filtering sound and fluids.

Chapter Two &#; How Perforated Metals are Made?

Various methods can be used to perforate metals. The key factor in the process is the type of sheet metal being used, which is typically thin and flat, making it easy to cut and bend. The thickness of the metal is measured in gauges, with higher numbers indicating thinner sheets.

Although perforated metals can have a wide range of shapes punched or stamped into them, the specific method used is less critical as long as it creates the desired holes. Common perforation techniques include using dies and punches or needles on a roller.

Making Perforated Metals

Metal Sheets

Soft metals such as aluminum and copper are generally easier to perforate, but most metals can be perforated with the right approach. The thickness of the metal is the most critical factor, as it determines the intensity required for punching or stamping. The intended function and specifications of the final product play a significant role in choosing the appropriate metal.

The metal's thickness impacts both the duration of the perforation process and the quality of the end result. Thinner metals are usually more cost-effective and easier to manipulate. The metal's strength is essential based on its application, whether for industrial purposes or decorative use. For decorative metals, their strength is influenced by their functional role, as they may act as structural supports or enhance the visual appeal of a structure.


Pattern Variety

Perforated metal sheets can feature a variety of patterns, each tailored to specific functions. Architectural patterns are often ornate and decorative, enhancing aesthetic appeal, while industrial patterns used for filtration, drainage, and screening are typically more uniform and practical.

Staggered patterns may include end patterns that are either finished or unfinished, with unfinished ends being the norm. An unfinished pattern means the holes at the edge of the sheet are incomplete, allowing sheets to be seamlessly aligned to create a continuous pattern when joined.

The margin in a pattern refers to the space from the edge of the sheet to the first perforation, creating a border around the sheet. In no-margin sheets, the pattern extends right to the edge of the sheet.


Method of Perforating

Several methods are available for perforating metals, with rotary pinned perforation rollers being among the most common. These rollers use pins or needles to create the desired shapes in the metal sheet. Rotary pinned perforation can be performed either hot or cold. In the hot process, the pin rollers are heated, resulting in holes with increased tensile strength. Cold rotary pinned perforation is used for thinner, more ductile materials, producing punctures with a distinctive volcanic appearance.

Other perforation methods include laser, plasma, water jet, die and punch, and nibbling. The choice of method depends on various factors, such as the desired speed and type of perforations.

Laser perforation is one of the most advanced and costly methods, offering high precision and accuracy. It provides results comparable to hot rotary pinned perforation but with superior control over size, dimensions, and pattern detail. The main advantages of laser perforation are its consistency and precise control over the final product.


Lubrication of Metal Sheets

Perforating metals can achieve up to 1,000,000 punctures per minute with remarkable speed, accuracy, and precision. The high-speed punching process generates significant friction due to metal contact, which requires a cooling method for the sheets after perforation. Light oil lubricant is applied to cool the metal sheets as they exit the punching process.

The other type is the XY axis machine, which offers different capabilities and applications.

    Wide Punch Press

    A wide punch press can have metal fed in sheets or coiled rolls. As the material passes through the machine, the ram rapidly descends on the metal, striking it with great force to produce a complete row of holes in one single motion. Wide punch presses can create perforated sheets rapidly in large quantities.


    XY Axis

    XY axis machines feature a single die or a cluster of dies attached to the ram. In this process, the material stays stationary while the ram moves across it to create the punches. Although the XY axis method is more time-consuming, it allows for the production of various shapes on a single workpiece.

    Typically, XY axis punch machines are CNC programmable, enabling precise control over the positioning of the metal sheet and the punching of holes.


    Rotary Pinned Roller

    A rotary pinned roller perforating machine features a large cylinder with evenly spaced pointed needles around its circumference. As the cylinder rotates, the sheet metal is pressed under the needles, which punch holes into the metal. This method is extremely fast and efficient, rapidly creating numerous holes as the metal sheets pass beneath the roller.


    Laser Perforating Method

    In contrast to rotary pinned roller and punch press methods, laser perforation is a non-contact process that uses lasers to burn precise holes into the metal sheet. This method offers exceptional accuracy and consistency, creating holes with a reinforced ring around them, similar to what is seen with rotary pinned roller hot perforation.

    Laser perforation can produce holes as small as five microns in diameter, which is significantly smaller than a human hair. The technique relies on directing a focused beam of light to a very small point on the metal sheet to achieve this level of precision.
