In order to add value to their customers, metal fabricators are increasingly adding powder coating to their offering. In-house powder coating means the manufacturer does not have to rely on an outside source for this process. Not only does this reduce the cost, since a separate company is not handling any part of the process, but there is less risk of damage to the parts; Damage that can occur when multiple people are handling a product. Less transport and less handling before the part is coated and thus protected means less risk. In-house coating also means schedules are easier to maintain and deadlines met. However, companies interested in installing an in-house powder coating line should investigate their options.

Why Powder Coating?

For metal fabricators, powder coating is the preferred finishing option because of its durability and resistance to general wear. Metal parts that are powder coated do not scratch, chip, or fade. Powder coating protects metal components from environmental factors, such as moisture and sunlight.

Batch vs Conveying Powder Coating Systems

One of the main options available that should be considered is the type of coating system. Powder coating systems are either batch or conveying. With batch systems, the parts are moved using rolling racks or carts, either in small batches, or singularly if it’s a larger piece.  With this process, human operators usually perform most of the actions.

A batch system is a good solution for:

  • coating parts that vary greatly in dimensions, for very large parts, or for complex shapes.
  • a shop where only a limited number of parts are coated each week.
  • initial cost is a significant factor; simple batch systems cost considerably less to purchase and install.
  • facilities with limited floor space; batch systems can be condensed to take up less space.
  • labor costs must be calculated. Batch systems may require more labor compared to automated systems.

An automated conveying system is best for:

  • parts that are more consistent in size and shape.
  • companies that have high throughput demands.
  • operations where a higher initial cost is justified; an automated system can cost between three and 12 times more than a batch. The cost of a manual conveyorized system falls between the two.
  • facilities with adequate floor space. A conveying system requires more floor space, especially if there is multistage pretreatment
