How to Choose the Right Automated Spray Coating System

Selecting the right automated spray coating system for your production line requires careful consideration. Here are the key factors to keep in mind:

• Throughput Capability: We can adjust our automated paint spray systems to match your part size, coverage needs, and high production throughput goals. Consider these factors when evaluating a system's potential cost-effectiveness.
• Expertise and Technology: Partner with an experienced manufacturer who offers the latest technology tracking material usage, waste reduction, and part quality control.
• PLC Integration: Choose a system with a PLC (Programmable Logic Controller) to track critical process data. This ensures consistent coating quality and allows you to trace results for future improvement.
• Safety and Environmental Compliance: When working with solvent-based materials, ensure the system meets all safety and environmental regulations.
• Automation vs. Robots: Robotic systems generally offer greater flexibility in spray gun positioning, achieving higher transfer efficiency and reducing changeover times. Compare robotic and automated systems based on your current and potential future needs.
• Batch vs. Continuous Processing: All of Arnold Machine's spray systems are suitable for batch processing. Consider options to improve efficiency if you have frequent changeovers due to a diverse product mix. Evaluate continuous operation systems to see if they meet your production needs.

Arnold Machine offers four primary spray system classifications along with complementary equipment to create a fully integrated setup:

Index spray machines and chain-on-edge spray machines: These versatile systems coat round parts on their inside or outside diameters.  The machine rotates parts during spraying, allowing for precise coverage with a stationary spray gun. Index spray machines have fewer part fixtures and spindles for longer cycle times. Alternatively, chain-on-edge machines allow for shorter cycles with a continuous or indexing motion.

Interior diameter (ID) tube spray machines: These machines are built specifically for coating very long tubes (up to 40 feet!). Temperature-controlled drying ensures complete interior coverage with faster cycle times and reduced material waste.

Tumble spray adhesive automation lines: Our tumble spray lines address shortcomings in traditional dip lines and are ideal for oddly shaped parts requiring total exterior coverage. Unlike index spray machines, tumble spray lines avoid witness marks.

Automatic viscosity bulk mixing stations: These complementary stations can integrate seamlessly with the spray systems we offer. Each station maximizes viscosity consistency while streamlining operation and offering complete process control.

Customized Spray Systems Designed for Paint & Adhesives

Our automated spray coating systems expertly handle both adhesives and paints. We prioritize safety features to manage the solvent-based nature of many adhesives. Precise temperature control ensures consistent dry film thickness, even with multiple coats of primers and adhesives. 

Some paints may require slightly larger spray gun nozzles due to their thicker viscosity. However, the benefits of these systems remain the same for both types of materials.

Automated Spray Systems that Focus on Safety & Process Control

At Arnold Machine, we understand that safety and efficiency are paramount in your manufacturing process. That's why we design Automated Spray Systems with integrated safety features and precise process control. Our engineers will customize a system to your exact specifications, optimizing material usage, reducing cycle times, and ensuring a safe work environment.

Our systems prioritize safety with features like interlocked spray booth doors, part sensors, over-temperature controllers, and airflow monitoring. Safety pull cords and manual/automatic fire suppression options are also available in operator work areas.

We currently offer two coating machines – automated and robotic – to give you superior control over your process. All systems feature automated temperature control, rotation speed, spray time, fan and atomization pressure, and gun positioning. For intricate patterns, robotic systems enhance automation with robots that precisely manipulate spray guns.

Every system features process control capabilities to monitor adhesive viscosity, control substrate temperatures, adjust air and fluid pressures, and ensure repeatable spray gun setups. These systems also recirculate material to reduce downtime and prevent chemicals from blocking lines or guns.

Automated Spray Coating System FAQ

• My parts vary greatly in size and shape. Can automatic spray coating machines handle this kind of diversity?

  Yes! The flexibility of our robotic and automated systems allows for significant variation between parts.  We can tailor spray gun positioning, rotation speeds, and other parameters to ensure optimal coating results for various components.

• How does an automated paint sprayer system affect the work environment compared to manual spraying?

  Automated spray systems significantly enhance the work environment. Enclosed spray booths minimize overspray and protect operators from harmful VOC exposure. Additionally, automation reduces the need for repetitive manual tasks, improving workplace safety and ergonomics.

• I'm concerned about the complexity of transitioning to an automated system. What support do you offer?

  We understand that transitions can be challenging. Our team offers comprehensive support throughout the process, from initial consultation and design to installation, training, and ongoing maintenance. We’ll work closely with you to ensure a smooth transition of your new automated spray system.
