Quick Guide to Industrial Finishing Systems and Paint Finishing Stages
High-quality finishes depend on a well-designed finishing system. Each part of the system plays a critical role in ensuring durability and the appearance of your product or component. If you’re coating aerospace parts, machinery, or small intricate parts, the stages of the paint process are just as vital as the components in your finishing system. Here is a quick guide to the essential components and stages of a finishing system.
Key Components of an Industrial Finishing System
- Pretreatment Equipment: Surface preparation ensures paint adhesion and long-term durability. Pretreatment systems include water wash stations, media blast booths, and rinse stages.
- Dry-Off Ovens: Parts must be dry before coating to prevent defects and improve finish quality. Dry-off ovens remove moisture to ensure effective coating adhesion.
- Paint Booths: The most critical component in a finishing system is the paint booth, providing a controlled environment to apply liquid and powder coatings.
- Paint Mixing Room: These are dedicated rooms for safe storage and mixing of paints with ventilation and temperature controls to keep your team safe and avoid toxic fumes in your workspace.
- Curing Ovens: Convection and infrared ovens are used after coatings are applied to harden finishes and ensure durability.
- Conveyor Systems: When adding automation to your finishing process, automated and manual conveyors are crucial to move parts through each stage of production.
Industrial Finishing Process Stages
The industrial finishing process is unique to each component or part. The material of your components or parts will have unique finishing requirements as well as the coating used. Here are the most common paint finishing process stages:
- Surface Preparation: This stage is for cleaning, degreasing, or blasting to remove oils, rust, or other contaminants.
- Drying: Surfaces need to be dry before applying primer or paint applications.
- Coating Applications: Using robots or manual processes to apply primer, basecoat, topcoat, or powder coatings inside a controlled booth environment.
- Flash-Off: This stage allows any solvents to evaporate before the curing stage.
- Curing: Using heat to cure coatings ensures paint or powder adhesion, chemical resistance, and long-term durability.
