Perforated Metal Conveyor Belts

Belt Technologies has the capability to design and produce perforated metal conveyor belts using stainless steel with custom perforation patterns. We can apply the variety of available patterns through specialized perforation methods to guarantee the belt you order is the best match for your application.

Custom Perforation Patterns for Any Application

Perforated belts are most commonly utilized in vacuum transportation, where the perforations allow air to pass through the vacuum plenum of the conveyor, creating a suction force to hold products and materials in position on the belt. This type of secure transportation method can be found in a variety of industries and applications, including:

  • Solar panel production
  • Printing presses
  • Packaging
  • Clean room environments
  • Electronics manufacturing
  • Pharmaceutical processing
  • Medical device manufacturing

Vacuum perforations are also used in a variety of automated systems where a change in elevation may cause products to shift on the belt.

In addition to vacuum suction, perforated belts can be used in a variety of automation tasks, including:

  • Carriage positioning
  • Indexing
  • Timing

The engineers at Belt Technologies have the knowledge and experience to give precise technical feedback to ensure your metal conveyor belt achieves positional accuracy and repeatability.

Perforation Methods and Techniques

A variety of methods can be used to create perforation patterns in stainless steel belts, such as die-and-cut presses, rotary-pinned perforation rollers, mechanical and laser cutting, and chemical etching. Some methods are more damaging to the structural integrity of the metal than others. This can effectively shorten the lifespan of the conveyor belt and inevitably cost time and money in the form of product volume loss each time the belt must be repaired or replaced. These challenges can often be overcome by consulting with our experienced sales engineers to determine optimal perforation patterns and methods in reference to your specific application.

All of our perforation techniques produce consistent, accurate, and precise perforations with no burr. Our in-house laser cutting services can create perforation patterns in metal belts that are more accurate and economical than any other perforation method.

Design Considerations for Perforated Metal Belts

Belt Technologies has the ability to perforate belts as thin as 0.002” or as thick as 0.031”. We can also perforate belts as narrow as 0.125” or as wide as 36”. We are able to perform a variety of perforation methods on a wide range of belt dimensions, which allows us the flexibility to accommodate a number of hole diameters and patterns.

A number of factors must be considered when selecting a perforated metal conveyor belt; failure to account for any one can mean getting the wrong metal belt for your specific application. For example, for most applications, we typically limit the open area of each belt surface to less than 30%. This prevents material deterioration and extends the lifespan of each belt. To make sure you address all technical aspects of your application (including those about open area, distribution, diameter, pitch, etc.), our engineers will work closely with your team throughout the entire process.
