Lexington invests in high-tech robotic painting system

Lexington Manufacturing has many years of experience painting window and door components manually. High-quality painting can be challenging, but we thrive on conquering challenging situations. That’s why we invested in a robotic painting system to increase accuracy, consistency, and to allow even faster output that’s ready to ship.

Manual painting challenges

Manual painting often requires at least a two-hour delay for drying. The technical aspects of painting manually also have many variables:

  • Viscosity of the paint
  • Temperature of the paint
  • The part being painted
  • The temperature and humidity of the plant
  • The painter’s endurance

These variables and many more provide a very narrow, operating window for successful manual painting.

Basically, if the paint won’t stick, it won’t work.

Robotic painting coverage is superior

Robotic paint coverage is accurate, consistent, and allows less waste.

Our robotic paint system produces finished components in sizes from 1 foot to 16 feet in just 18 minutes—from entry into the booth, to being painted, fully dried, and ready-to-package for shipping.

The robotic painter can be utilized in two different modes: “Follow-me” mode or CNC mode. In Follow-me mode, the robotic arm sprays over the entire part, which is effective for components with less complexity.

In CNC mode, the operator writes a CAD program that instructs the robot’s reciprocator arm to spray at various angles and for specific amounts of time, to apply an exact amount of paint. This reduces wasted paint and overspray on intricate components, while providing consistent coverage, every time. We can even change profiles when programmed and loaded ahead of time.

Other paint systems, such as electrostatic, are less precise and harder to control. Companies can struggle with profiles that have a large number of peaks and valleys, highs and lows. An electrostatic painting system isn’t designed to reach these grooves, where Lexington’s CNC robotic painting system is.

Elevator oven dryer allows better airflow

Our two-stage elevator oven dryer can also be set with different temperatures and airflow to provide the precise level of finish needed for the part. More airflow early in the drying process adds gloss—less air later in the process brings a matte finish.

With robotic painting, we purposefully assist our customers by bringing the entire process of finishing components under one roof. We buy the material, profile wrap the component, paint and dry the unwrapped part, and then ship it—ready to be installed into the window.

Consistent, ready-to-assemble components

With seven profile wrappers and the engineering to support it all, and now our robotic painting system, we provide ready-to-assemble components for the window and door industry—consistently.

Every part we ship is identical in quality and identical in production cost.
