The term “paint finishing” encompasses all processes engaged in the application of paint or finishes to a surface. These processes use all kinds of machines and tools, broadly called paint finishing equipment, to apply both functional and aesthetic finishes. Finishing coats, especially, are used to provide surfaces with one or more layers of protection against chemical agents and environmental impact.
To these ends, finishes and paints vary greatly, offering characteristics related to sheen, hardness, color, durability, and more. The applications of paint finishing equipment range from at-home projects, like the painting of one’s house, to large manufacturing ventures that require automated or robotic paint finishing equipment.
Some of the most common and basic paint finishing equipment include heat guns, air brushes, and paint rollers and brushes. Tools that often accompany these include roller trays, drop cloths, painter’s tape, dip sticks, and sandpaper. These types of tools are usually used to apply paint and paint primer during at-home projects, like wall painting.
Another machine commonly used with small-scale painting projects is the paint mixer, which mixes the contents of a sealed can of paint by rotating, spinning, inverting, shaking, and rocking it at high speeds. More advanced, industrial painting projects often employ paint machines, which are automated systems that use conveyors and robots to speed up and streamline the painting process. Read More…
Another popular paint application device is the paint sprayer, which is a triggered gun that sprays paint in even, thin coats. A similar piece of equipment is the pressurized paint reservoir, which consists of a compressed air system and connective tubing. The basic spray painting system configuration consists of a nozzle, an air compressor, a pressurized paint container, and tubes or hoses to connect them.
Spray painting systems as a whole are valued for the superior quality of the finish they leave, as well as the efficiency they generate by applying paint faster and wasting less paint than rolling or brushing systems. A piece of paint finishing equipment that often accompanies spray painters is the paint booth. A paint booth is a portable structure designed to both contain potentially hazardous paint fumes and overspray, and to keep out contaminants like dust that could ruin a smooth application of paint. Paint booths, sometimes called spray booths, are available in a variety of designs, from small cabinets to entire rooms.
In addition to these generalized paint finishing tools and machines, manufacturers produce some paint finishing equipment that is very application specific. One such type of equipment is powder coating equipment, also called electrostatic painting equipment, facilitates a special kind of spray painting that works with electrically charged powder in place of liquid paint. To work, both the powder and the product are electrically charged particles, ensuring that that powder, when sprayed, will be strongly attracted to the metal surface of the product.
Similarly, an airless paint sprayer produces a fine mist of paint via a hydraulic pump instead of an air compressor. Airless paint sprayers are valued in chemical, marine, and industrial applications, where they apply coats of paint extremely evenly and with a level of wetness that ensures superior adhesion, flow-out, and penetration of pits and crevices. Another specialized paint finishing device is the striping machine, which exists to paint lines. Striping machines supply lines in parking lots, on roads, on airport runways and on the dirt and grass of playing fields. Like most paint finishing equipment, striping machines consist of an air compressor, a spray nozzle, a small engine, and a series of hoses and valves.
To improve the relationship between the environment and painting and finishing applications, scientists and engineers are developing new alternatives to traditional paints and solvents, which threaten the environment and contaminate water supplies when disposed. At the same time, mechanics and engineers have found and continue to find and create new ways to decrease drying times, increase efficiencies and improve motors and engines.
As motors and engines shrink in size, they become less likely to break and require less fuel or power to operate. In addition, paints, stains, finishes, and other coatings have seen great strides in recent years, improving chemically and exhibiting greater viscosity and molecule cohesion. Only time will tell what the future holds for paint finishing equipment, but to get started with the resources available today, reach out to a paint finishing equipment supplier.
