Liquid Painting Systems

Built for Performance, Designed to Last

At Precision Conveyor, our liquid finishing systems are designed around your parts and your process—not some off-the-shelf kit of mismatched components. Every project begins with a deep understanding of your coating requirements, throughput goals, floor space, and operational challenges. From there, we engineer a complete system—from conveyor to spray booth to oven to controls—all built for durability, accuracy, and ease of maintenance.

What We Build In-House

Unlike integrators who assemble systems from third-party components, we design and build all major equipment in-house:

  • Chain-On-Edge Conveyors – Smooth, accurate part transport with built-in rotation or indexing
  • Spray Booths – Designed for proper airflow, overspray capture, and operator safety
  • Ovens – Gas or electric convection or infrared, with uniform temperature control
  • Automation – Robotic loaders, gun movers, indexing logic, part tracking
  • Fixtures – Precision tooling for consistent orientation and coverage
  • Controls – Allen-Bradley PLCs, HMI touchscreens, part tracking, and diagnostics

Built on a Chain-On-Edge Conveyor Foundation

All our liquid coating systems are based on our proven Chain-On-Edge (COE) conveyor technology. These conveyors provide:

  • Part stability during rotation or indexing

  • Process accuracy with consistent spacing and speed

  • Mechanical robustness for demanding environments

Fluid Handling & Delivery

We’re not tied to any single brand. That means we can select the best components for your specific application, and design the fluid handling system around it:

  • Electronic spray gun, pump, and agitation pneumatic control

  • Online solvent or flush supply

  • Circulating or direct-feed fluid delivery systems

  • 2K meter/mix systems

  • Pressure pots with agitators

  • Pump-fed systems from day tanks or 55-gallon drums

  • Automatic color change systems

  • Automatic flush systems

We design every system with transfer efficiency in mind—getting more paint on the part and less in the air.

Pretreatment Capabilities

Prior to painting, your product may require preparation. We’ve developed a range of integrated pretreatment solutions:

  • Washing and Dry

  • Grit Blasting

  • Pre-Heating

  • De-stat Blow Off

  • Masking

Drying, Curing, & Cooling

Our ovens are custom-designed for your part, process, and performance requirements:

  • Electric Infrared

  • Gas Catalytic Infrared

  • Ultraviolet

  • Convection (Gas, Electric)

  • Cooling Enclosures (Forced Air)

Controls & Automation

All control systems are designed and programmed in-house by Precision Conveyor:

  • PLC-Based (Typically Allen-Bradley CompactLogix)

  • Touchscreen Interface

  • Part Tracking

  • Fault Detection

  • Production History Tracking

Safety Systems

We take operator safety seriously. Every system includes proven safety mechanisms:

  • Guards / Fencing

  • Light Curtains

  • Pull Cords

  • Door Interlocks

  • Push Button E-Stop Stations

  • Air Flow Sensors

Light curtains and perimeter fencing deliver Category 4 operator protection without slowing production.

Code Compliance

Our designs meet or exceed applicable codes for painting and coating systems:

  • NFPA 70 (NEC)

  • NFPA 79

  • NFPA 86 (Ovens and Furnaces)

  • CE / UL

  • CSA / TSSA (Canada)

  • OSHA

Maintenance Is Not an Afterthought

We incorporate features that make maintenance safer, faster, and less disruptive:

  • Oven access doors with work lights

  • Spray booth access doors for filter change

  • Overspray collection baffles

  • Observation windows

  • Conveyor maintenance zones

  • Auto lubrication systems

Many of our systems remain in operation after 30+ years in tough environments. That’s not luck—it’s deliberate design.

Installation, Startup & Training

Every Precision Conveyor system comes with hands-on support:

  • On-site installation and interconnect

  • Startup and debug with customer maintenance team

  • FAT (Factory Acceptance Testing) at our facility

  • Operator and maintenance training

From first bolt to final startup—our team takes pride in delivering systems that run right and look good doing it.

Proven Platforms & 3D Design

Our systems may be custom-built, but they’re never experimental. Every solution starts with a proven mechanical foundation and is modeled in full 3D using Autodesk Inventor before a single part is fabricated. These digital prototypes ensure proper fit, flow, and maintainability—and give your team a clear picture of how it will all come together.

We sweat the pixels so your team doesn’t have to. Inventor models help us catch conflicts, plan service access, and lock in performance before steel hits the floor.

Frequently Asked Questions

How much do your systems cost?

 Systems typically range from $50,000 to over $1 million depending on complexity. We always aim for the most economical design that meets your needs.

Typical lead time is 12+ weeks from order, depending on system size and backlog.

 Ideally, part drawings, weight, coating type, desired throughput, and available space. But we can start the conversation with just a photo and a goal.

 Very little. Most customers run for years with minimal upkeep. Nobody wants to maintain a dirty paint line.

 Yes. With small-radius turns in our COE design and optimized layouts, we’re able to fit systems into extremely constrained footprints.

 Yes. We can design our conveyor, ovens, and automation to work with existing spray booths, controls, or robots.

This is generally not done in liquid systems due to contamination risk. However, we can design for minimal waste and high transfer efficiency.

Yes. We regularly build indexing systems that stop parts in front of spray guns for consistent coating.

Yes. Many of our customers are open to site visits.

We provide immediate support from our engineers. That said, most of our systems run trouble-free for years.

We typically provide full systems, but are happy to quote conveyors, ovens, or controls as standalone solutions.

Yes. We regularly upgrade ovens, controls, and conveyors on legacy systems.

We build nearly everything in-house, focus on longevity and serviceability, and never hide behind a catalog of mismatched components.
