Solution Overview

Problem

Existing coating methods struggle to achieve uniform coating thickness and uniformity on complex or irregular substrate surfaces, particularly in large structures, and lack effective control over environmental and substrate parameters during the coating process.

Innovation Solution

A system with detectors and a controller that regulate the release of coating material based on detected environmental and substrate parameters, including ambient conditions and substrate characteristics, to ensure uniform deposition and adjust the coating process accordingly.
