The Key Advantages of Laser Cutting
Laser cutting is a subtractive manufacturing technology that uses a high-powered, focused laser beam to vaporize, melt, or burn materials with extreme precision. Its popularity spans industries from aerospace and automotive to jewelry and signage due to its numerous compelling advantages. 1. Superior Precision and Exceptional Cut Quality Extremely Narrow Kerf: The laser beam is incredibly […]
The Superior Advantages of 316L Stainless Steel
316L stainless steel is a low-carbon variation of the classic 316 alloy and is a cornerstone of the austenitic stainless steel family. Its “L” designation stands for “Low carbon,” which is the key to its enhanced properties. It is renowned for its exceptional corrosion resistance, excellent mechanical properties, and versatility across a wide range of […]
Application of aluminum powder coating
Vehicle parts Powder coating meets the wear and corrosion resistance requirements of vehicle parts, most notably auto wheels and motorcycle frames. Architectural components Powder coating enhances the scratch resistance and aesthetics of aluminum architectural components such as handrails, curtain walls, and patio furniture. Electrical application Computer housings, lighting fixtures, and other application parts […]
Advantages of aluminum powder coating
Corrosion resistance Compared to traditional coatings, powder coatings are thicker and can delay corrosion and oxidation on their surface. Color diversity Aluminum powder coating allows you to flexibly choose a variety of colors or finishes(like metallic or textured) to spray on the surface of aluminum parts, which provides more options for customized product design. […]
How to powder coat aluminum?
Pre-processing Cleaning Before powder coating, it is necessary to use alkaline or neutral degreasers to thoroughly clean the aluminum surface to remove grease, dust, or oil stains that may affect adhesion. Sandblasting Sandblasting enhances the roughness of aluminum surfaces mechanically, thereby improving the adhesion of powder coatings. Pickling Pickling is a chemical process […]
Types of Powder Used in Aluminum Powder Coating
Thermosetting Plastic Powders Thermosetting plastic is the most used material for powder coating, and the common types used for aluminum parts are: Epoxy, Polyester, and PU. During baking, it melts and cures, forming a permanent coating on aluminum through a chemical process called crosslinking. This coating is hard, has overall better wear and chemical resistance […]
Why can aluminum be powder coated?
The good conductivity of aluminum ensures that it adheres evenly to aluminum parts through electrostatic adsorption when powder coating. Aluminum’s excellent heat resistance (melting point of 662°C) ensures that the workpiece will not deform during the baking process of powder coating. Aluminum has a natural oxide film (Al₂O₃) on the surface, which has a certain […]
What is powder coating?
Powder coating is a dry surface treatment for metals, including aluminum. It uses a specialized spray gun to apply finely ground dry powder(made from resins such as epoxy and polyester) onto the surface of metal parts. After high-temperature baking(typically 160℃-200℃), the plastic powder will melt, level out, and cure, ultimately forming a coating […]
Types of black oxide
Based on the operating temperature and the chemical solvent used, black oxide is generally divided into the following types: Hot black oxide The hot black oxide process operates at 140℃- 155℃. Immerse the metal workpiece in strong alkaline solutions such as NaOH and NaNO₂ to form a deep black and wear-resistant film on its […]
What is black oxide?
Black oxide, which is also called blackening, is a type of chemical conversion coating process mainly applied to ferrous materials like steel or iron. The metal reacts chemically with a specific alkaline oxidising solution to produce an extremely thin layer of iron oxide(Fe₃O₄) film. This film(about 0.5-1.5μm)is uniformly black and tightly bonded to the metal […]
