| Coating (Painting)
As a precision CNC machining services supplier, we understand the importance of ensuring that the end workpieces not only meet functional requirements such as durability and scratch resistance but also have an appealing aesthetic appearance. Coating plays a significant role in achieving these objectives.
The choice of coating operations at Overland depends on factors such as the desired color, specific features required, and the intended functions of the workpieces. Coatings can serve both decorative and functional purposes, and we take into consideration your specific requirements to determine the most suitable coating operation for your workpieces.
By carefully evaluating factors such as color options, desired features, and functional requirements, we can select the appropriate coating operation to enhance the performance, durability, and visual appeal of your CNC-machined workpieces.
| Liquid Coating
As a precision CNC machining services supplier, we understand the importance of meeting functional requirements such as durability, scratch resistance, and aesthetic appearance for workpieces. Coating plays a crucial role in achieving these goals, whether it’s for decorative, functional, or both purposes.
In order to determine the appropriate coating operations, we collaborate with our trusted coating partners. Based on the specific color, features, and desired functions of the workpieces, our coating partners utilize liquid coating systems that offer the advantage of color change capability.
Liquid coating systems allow for quick color changes by regulating the Lab color space. This mathematical model describes all perceivable colors in terms of lightness (L), and the color-opponents green-red (a) and blue-yellow (b). This means that with liquid paint, the color can be mixed on-site to meet specific color specifications.
By leveraging liquid coating systems and working closely with our coating partners, we ensure that the color, features, and desired functions of your workpieces are achieved to meet your requirements.
| Powder coating
As a precision CNC machining services supplier, we understand the importance of meeting functional requirements and achieving a great aesthetic appearance for workpieces. Powder coating, as a distinct alternative to liquid coating, offers several advantages in terms of durability, scratch resistance, and resistance to outdoor conditions.
Powder coating can provide both decorative and functional benefits, allowing us to meet your specific requirements effectively. Our coating partner offers various coating operations and special effects to achieve the desired color, features, and functions for your workpieces. Some of the special effects commonly used in our powder coating projects include:
Plain type powder coating: This is a standard powder coating option that provides a smooth and uniform finish.
Hammer type powder coating: This special effect creates a textured surface with a hammered appearance, adding visual interest to the workpiece.
Texture type powder coating: Texture powder coating results in a textured surface finish, offering a tactile element and enhanced visual appeal.
Wrinkle type powder coating: This special effect produces a wrinkled or crinkled texture on the surface, providing a distinctive and unique appearance.
| Electro Deposited Coating
Electro deposited coating, also referred to as electrocoating, electrophoretic coating, or electrophoretic painting, involves the deposition of pigments or dyes onto a workpiece. This process is particularly useful for applying coatings to electrically conductive CNC machining parts. Workpieces that undergo electro deposited coating exhibit several beneficial characteristics, including:
Reduced friction: The coating helps reduce friction between moving parts, resulting in smoother operation and improved performance.
Uniform/even coating: Electro deposited coatings provide a consistent and uniform coating thickness across the entire surface of the workpiece, ensuring optimal coverage.
Enhanced wear resistance: The coating adds a protective layer to the workpiece, increasing its resistance to wear, abrasion, and damage caused by friction or external factors.
Anti-corrosion resistance: Electro deposited coatings act as a barrier against moisture, chemicals, and environmental factors, protecting the workpiece from corrosion and extending its lifespan.
Environmentally friendly (RoHS compliance): Electro deposited coatings are formulated to be environmentally friendly and comply with RoHS (Restriction of Hazardous Substances) regulations, ensuring safe and sustainable manufacturing practices.
