Automatic Spray Coating Line: What Are the Advantages?

An automatic spray coatingline created as a brand new design effectively implemented within a pre-existing working plant can truly revolutionise most finishing processes. How? By offering a number of tangible (and measurable) advantages compared to traditional techniques (especially manual processes) and ensuring a fast return on investment. In this feature, we will review the parts that make up an automatic spray coating line and explain how this type of solution improves end product quality and reduces operating costs.

Automatic spray-coating line set-up

By working in synergy, automatic spray coating machines can create simple or complex lines, with flat and vertical configurations, including elliptical designs and sophisticated anthropomorphic robots. The whole system is equipped with advanced software to ensure total control over the process and, consequently, the best possible performance in any use condition.

An automatic spray coating line can be used for finishing surfaces made of different materials, such as wood, ceramic, metal, glass, fibre cement and plastic. Depending on the application, specific process parameters and interchangeable tools are required.

Without going into too much detail, we analyze the types of available spray machines:

  • Oscillating spray coaters, with one or two arms: these machines meet the needs of manufacturers who need to process small-, medium- and also large-sized production volumes.
  • Rotary or elliptical spray coaters: perfect for customers looking for maximum performance in terms of productivity and speed, without ever compromising on quality. The high number of guns in these spray coaters allows for uniformity of application.
  • Coating robots: these automation solutions guarantee high outout and at the same time very high finishing quality. In particular, robots that work horizontally ensure flexibility, speed and precision. Configurations with one or two robots operating in stationary load or oscillating mode are possible. Thanks to computer technology and tracking functions, two robots are able to work simultaneously on the same item, dramatically reducing processing times.

Advantages of an automatic spray-coating line

Let's now review the advantages of installing an automated spray coating line, especially when compared to using manual methods.

As can be easily understood, the automated spray coating technique in itself guarantees greater transfer efficiency and consequently - lower paint consumption (and related costs). In addition, it improves the quality of the end product, not to mention the level of homogeneity that can be achieved even on complex surface designs and the possibility of always processing deliveries in predictable times.

Automation adds extra benefits to spray coating techniques: just think that even by employing qualified personnel, it will not always be possible to achieve the coating quality standards required by customers. There are too many variables that could affect the performance of a finishing line based on manual workmanship. An employer's most experienced operators, for example, could become ill and be temporarily replaced by less skilled personnel. All of this often leads not only to inferior results but also to wasted paint, time and substrates (therefore, to a waste of money).

These potential critical issues could all be resolved by introducing automated spraying equipment.

Results and benefits of automated spray coating

Regardless of the industry you operate in (automotive, furniture or consumer durables), choosing equipment to create an automated spray coating line can lead to several benefits also in terms of output:

  • Guaranteed high quality finishes and consistency, also based on specific customer requests;
  • Flexibility in every phase of the process: possibility of processing small batches efficiently, including customisations and special processes;
  • Transfer efficiency and productivity: essential for securing good margins. This is thanks tosoftware solutions and the IoT (Internet of Things), which help monitor processes and optimise every step, while patented technologies increase productivity;
  • Constant innovation, thanks to the development and integration of increasingly high performance and effective tools and methods into automatic spray coating lines.

These factors ensure greater competitiveness in a market that requires shorter delivery times, lower costs and better quality.

Benefits of Automated Spray Coating Systems - Dubois Equipment

The liquid finish on many products is essential for protecting materials from corrosion, UV damage, abrasion and more. Some manufacturers use manual spraying methods to coat their products. However, manual spraying can be inefficient, expensive and unsafe.

Investing in automated metal coating machines can benefit your manufacturing company in numerous ways. The advantages include reducing costs, reducing waste, increasing output and improving workplace safety. We take a look at these automatic pipe coating machine benefits in the guide below.

1. Reducing Waste and Costs

Automatic spray coating equipment eliminates waste and reduces costs in a few ways.

Reduce Bounce-Back and Overspray

Bounce-back and overspray are typical issues when applying liquid finishes with manual coating spray equipment. They both cause a significant amount of product waste. In comparison, automated spray systems are far more accurate and precise. They continuously adjust the nozzle, spray height and volume of fluid dispensed when coating products. The result is that less liquid is wasted when spraying products.

Ensure Consistent Finish Application

Coating spray equipment also ensures uniform application of finishes to oddly shaped parts and hard-to-reach interior areas. A consistent application of coatings onto products can help limit the need to scrap or re-spray products that have been incorrectly coated.

The flexibility of spray machines to cover nearly any shaped product means you save time adjusting the position of what you are coating. A range of different products can also be sent along the conveyor belt instead of just one product at a time.

Boost Productivity and Savings

As a result of this flexibility and accuracy when spraying products, automated spray systems can reduce wasted time in manufacturing. There is less time spent adjusting products and the spraying machine, so the automated system is more efficient.

Metal coating machines require less downtime than manual sprayers when changing spray setups. Once you have programmed different coating types for specific products, you can switch between them quickly. The machine adjusts the spray level, nozzle position and more accordingly.

Automated spray coating machines are also versatile. They can spray various liquids including paint, stains, protective coatings and finishes. This versatility means that you can invest in one device with multiple functions instead of several machines that each have one function. 

Automatic spray coating systems need less human intervention and monitoring. Employees now have more time to focus on tasks that require intense concentration and human skill.

2. Increasing Workplace Safety

A significant benefit of automatic spray coating systems is that they can enhance workplace safety. Many of the chemicals used in spraying and finishing applications are toxic properties or flammable. They can present a severe health risk to human operators while spraying products.

Eliminate Air-Borne Chemicals

Automated systems are typically enclosed. Products pass under the spray nozzle that is held within a covered compartment. This setup eliminates the spraying of dangerous and volatile chemicals into the air, leading to a lower risk of long-term health problems for employees or accidents in your facility.

Filters in automated machines also keep chemicals or pollutants from escaping the system and entering the air in the factory. Workers spend less time handling these hazardous materials, reducing the possibility of spills and contact with dangerous chemicals.

Reduce Slip Hazards

These systems also reduce slipping hazards in your facility by ensuring a cleaner work environment. If there is any excess coating and finish liquids when spraying, they remain in the enclosed spraying systems rather than gathering on the floor during production. Workers no longer have to worry about falling due to slippery equipment or floors. A clean workplace is a safer workplace.

3. Improving Output Amount and Quality

Being able to increase your output without sacrificing quality is essential. The more high-quality products you can produce quickly, the more orders you can take. Automated metal spray coating machines can help — they can increase the speed and the quality of the coating. Together, these two features enable you to improve the output and quality of the goods you manufacture.

Spray Items More Quickly

Automated pipe coating machines are considerably faster than manual spray coating. Automatic spray coating systems can spray large quantities of products in a short amount of time, increasing your output drastically. If you manufacture large products or parts, they can take hours or even days to coat when spraying manually. Automated coating machines can significantly reduce the time it takes to finish spraying large products, allowing you to complete more orders over time.

Experience Less Downtime

Further, there is less downtime between changing liquid coatings or colors. You can then coat multiple batches of different products with varying finishing requirements in a shift. There is no need for manual adjustments or tooling changes that can waste manufacturing time.

Once you have programmed different colors or spraying needs into a machine, you can switch between them by pressing a few buttons. The ability to rapidly change between coatings is essential if multiple batches of products need to be sprayed in different colors or with different finishes.

Achieve Even Sprays

Inconsistent spray coating can result in lower-quality products and increase the need for touch-ups and reworks. Automatic spraying systems coat products with a uniform and consistent thickness to ensure complete coverage and a high-quality finish.

Every product has the same level of coating on every part when sprayed by an automated coating system — there is no overlapping coating from over-spraying or spots missed resulting in cleaner finishes. This quality remains the same with every batch, resulting in consistently high-quality products.

The consistent quality of products saves time in manufacturing, resulting in higher outputs for your facility.
