Surface Finishing

Metal surface treatment allows you to enhance your product’s appearance, performance and lifespan. The Komacut platform simplifies obtaining sheet metal parts with your preferred surface finishing at mass production quality and pricing by offering a range of standard metal surface treatments, in a variety of colors and finishes. Simply upload your drawings to receive instant quotation for sheet metal parts with a range of advanced surface finishing options. Our system will provide real-time feedback on what surface treatments are available for your part’s size and geometry, as well as providing examples, technical information and photo galleries of the finishes available – allowing for quick and easy choice of the optimal finish for your project. You can learn more about various surface finishing options below:

Powder coating is a dry finishing method that produces high-quality, long-lasting finish while allowing for increased productivity, efficiency, and easier environmental compliance. Powder coatings are available in sheer range of colors and textures, and technological improvements have led in exceptional performance attributes. They are used as protective and decorative finishes whether its powder coated steel or other materials. There are a wide range of powder coating colors and textures available, including both glossy and matte finishes.

The surface is immersed in a pool of liquid paint that is subsequently electrified during the e coating process. The amount of electric current delivered to the liquid determines the coating thickness. This enables extremely fine coating thickness control and uniform film layers. The thinness and evenness of the coating allows for very tight part tolerances for high precision parts.

Zinc plating is commonly used to protect metals like iron and steel from the corrosive forces. It involves the electrodeposition of a thin layer of zinc metal onto the surface of another metal item. In zinc plated parts the zinc coating acts as a physical barrier, preventing rust from accessing the metal. This process is often used with screws and other small fastener and parts that will be exposed to corrosive conditions.

Anodizing is an electrochemical technique that converts the surface of aluminum to aluminum-oxide. The outcome is a coating that is reasonably hard, inert, electrically insulating, and absorbent. Because it is an inherent component of the aluminum, an anodized layer provides exceptional adherence. Anodizing allows for a range of particularly vibrant colors to be added to aluminum parts.

Passivation of stainless steel is used after machining or other detrimental processes to restore the corrosion-protective oxide coating. This top layer adheres to the metal securely, forming a natural seal that prevents the elements from corroding the metal's subsequent layers.

Galvanizing sheet metal is a rust-prevention procedure in which zinc is applied to steel to prevent rusting. The zinc coating protects the underlying metal. It accomplishes this by functioning as a corrosive element blocker. Galvanized metal will have increased strength, and better endurance.
