How Sign Manufacturers Can Automate Spray Finishing and Reduce Labor Costs

Automated spray finishing for sign manufacturers is becoming essential as shops look to increase production, improve consistency, and control coating costs across a wide range of substrates.

Sign manufacturers operate in a unique production environment. Unlike high-volume manufacturing, most shops are running short batches, one-offs, and highly customized jobs across materials like wood, MDF, acrylic, plastics, and metal.

Finishing these parts manually with a spray gun works, but it creates a bottleneck that limits growth.

The challenge is clear. How do you increase output and consistency without adding more labor, especially when every job is different?

Common Challenges for Sign Manufacturers

Spray finishing in sign manufacturing comes with a specific set of challenges:

• Short runs and frequent customization requiring constant adjustments

• Limited throughput tied directly to labor availability

• Inconsistent finish quality between operators or shifts

• Frequent color and coating changes slowing down production

• Operator fatigue from repetitive manual spraying

  
  

Because no two jobs are exactly the same, efficiency is often sacrificed for flexibility.

The result is a finishing process that is difficult to scale.

Why Hiring More Sprayers Isn’t Always the Answer

When production increases, the first instinct is often to add more people.

But in a sign shop, that’s not always practical.

• Workloads fluctuate

• Jobs vary in size and complexity

• Training new operators takes time

Adding labor increases overhead without guaranteeing consistent output or quality.

This is why many sign manufacturers begin exploring automated spray finishing. Not to replace flexibility, but to support it.

A Key Challenge: Expensive Coatings and Small Batch Sizes

Many sign manufacturers use:

• Adhesion promoters

• Specialty paints

• Protective topcoats

These coatings are often more expensive and often used in smaller quantities.

At the same time, jobs require:

• Frequent color/coating changes

• Different coatings throughout the day

• Minimal waste

A common concern is that automation requires large volumes of coating to be efficient.

Can Automation Work for Short Runs and Small Volumes?

The answer is yes, if the system is designed correctly.

Instead of relying on large material reservoirs, modern automated spray systems can use small, localized fluid delivery.

A solution like a compact pressure pot mounted directly on the spray arm, often called a Speedy Cup, allows you to:

• Run small batches without wasting material

• Perform quick color or coating changes

• Maintain flexibility for customized jobs

• Use only the amount of coating needed for each run

This makes automated spray finishing practical for sign manufacturers producing short runs and custom work.

How Automated Spray Systems Improve Sign Production

Automated spray finishing systems are increasingly used in sign manufacturing to apply coatings on materials like acrylic, aluminum, MDF, and plastics.

They are especially effective for:

• Base coating panels before routing or engraving

• Applying adhesion promoters prior to graphics

• Spraying protective topcoats on finished signage

• Consistently coating a wide range of substrates

Instead of relying on operator technique, automation delivers:

• Repeatable spray patterns

• Consistent film build

• Predictable results across every part

Just as important, modern systems are designed to handle short runs and frequent changeovers, making them well suited for custom sign production.

Features That Matter for Sign Manufacturers

For automation to work in a sign shop, it has to reduce waste, simplify changeovers, and handle variability.

Systems like the Mini Plus Automat Spray machine are designed with these needs in mind:

Reduced Overspray and Material Waste

A pressurized spray cabin helps contain overspray, improving transfer efficiency and reducing coating consumption.

Smart Part Detection

A photo diode detection system identifies the size and position of each part, allowing the machine to spray only where needed. This minimizes overspray and improves consistency, even with different part shapes and sizes.

Efficient Material Usage for Small Runs

The Speedy Cup system allows operators to run small amounts of coating directly from a compact pressure pot mounted on the arm. This is ideal for short runs, custom jobs, and expensive coatings.

Fast, Consistent Color Changes

An automatic color and coating change system, controlled through the touch screen, allows for:

• Faster transitions between jobs

• Reduced coating waste during changeovers

• Elimination of operator error

Easy Cleanup and Waste Management

A paper belt system continuously moves beneath the spraying area, making cleanup simple and reducing downtime between jobs.

Real-World Example: Automation in a Sign Manufacturing Environment

One sign manufacturer in the Northeast implemented a Mini Plus automated spray system to improve efficiency across a wide range of coatings and short-run jobs.

Their setup includes:

• A 3+1 fluid management system with Sames pumps and guns

• Integrated automatic color and coating change

• A Speedy Cup system for small batches and specialty coatings

• A laminar dryer to support throughput after spraying

In daily operation, they run:

• Primer

• Topcoat

• Adhesion promoter

Using the automatic change system, they can quickly switch between these coatings without manual intervention, reducing downtime and minimizing material waste.

For smaller runs or higher-cost coatings, they utilize the Speedy Cup to maintain efficiency without overcommitting material.

This combination allows them to:

• Handle high-mix, low-volume production

• Maintain consistent finish quality

• Reduce labor involvement in the spraying process

• Improve overall workflow efficiency

Choosing the Right Automated Spray System for Your Shop

Automation in sign manufacturing doesn’t need to be large or complex to be effective.

The right system should:

• Handle short runs and customization

• Support frequent color and coating changes

• Minimize material waste

• Fit within your existing workflow

Compact automated spray systems provide a practical way to increase efficiency without sacrificing flexibility.

Will an Automated Spray System Fit in Your Shop?

One of the most common concerns among sign manufacturers is space.

Many shops operate in tight production environments, with limited floor space and low ceiling heights. Adding new equipment can feel unrealistic, especially if it requires major layout changes.

The good news is that automation doesn’t have to mean large, complex installations.

Compact systems like the Mini Plus Automated Spray machine are designed specifically for smaller footprints, allowing sign manufacturers to introduce automated spraying without disrupting their entire operation.

Beyond the machine itself, layout matters.

Superfici America works with customers to:

• Develop custom layout drawings based on your available space

• Optimize equipment placement within your existing workflow

• Ensure proper fit, even in rooms with limited ceiling height

• Integrate supporting components like dryers without overextending your footprint

In real-world applications, systems like the Mini Plus paired with a laminar dryer have been successfully installed in small rooms with constrained space, proving that automation is possible even in compact sign manufacturing environments.

If space has been a barrier to automation, the right system and layout approach can make it achievable.

What to Expect When Implementing Automated Spray Finishing

For many sign manufacturers, the biggest hesitation around automation isn’t the technology. It’s the implementation.

Questions like:

• Will this system work with my coatings and materials?

• How do I know it will perform the way I need it to?

• How difficult will it be to get up and running?

A successful transition to automated spray finishing starts with the right process.

At Superfici America, that process includes:
