What is Surface Treatment?
Surface Treatment is a technique used to alter or enhance the properties of a material's surface to improve its durability, aesthetics, and functionality. This process is typically applied to metals, plastics, and glass, adding one or more protective or decorative layers. Surface treatment is crucial for improving corrosion resistance, wear resistance, and the visual appeal of parts.
Surface Treatment Types - Process Overview
At Yuhui, we offer a range of high-quality surface treatments designed to improve corrosion resistance, aesthetics, and product lifespan. Our surface treatment processes adhere to environmental standards, promoting sustainable and green manufacturing.
Painting
Our painting service uses a variety of eco-friendly coatings for precise application on diverse surfaces, delivering customizable color options and a smooth, decorative finish.
Powder Coating
This process provides high hardness, corrosion resistance, and scratch protection for metal surfaces. It is ideal for industrial products and outdoor equipment, ensuring long-lasting durability.
UV Coating
Using ultraviolet curing, this treatment enhances surface wear resistance, chemical resistance, and lifespan. UV coating is suitable for precision parts that require a high-quality, durable finish.
