Barrel plating is a well-established surface treatment process. It involves placing a fixed quantity of small metal or plastic parts into a specialized rotating drum, which is then placed in an electroplating tank. The rotation of the drum causes the workpieces to collide and conduct electricity, allowing the metal to be deposited on their...
Passivation treatment is a common process in the industry. Its main purpose is to add a protective layer to the metal surface, improving the corrosion resistance of the workpiece and extending the product's lifespan. It is a very important surface treatment process.
Stainless steel is a metal we often hear about and see in our daily lives. Its most relevant applications are in insulated cups, tableware, and kitchenware, while it extends to building materials and equipment parts. This metal plays an indispensable role in our lives. In Taiwan, it has other names, such as stainless acid-resistant steel or water...
In the surface treatment industry, people often mention "electrodeposition." What is it? Electrodeposition is a coating technology that uses an electric field to cause a charged coating to migrate directionally through a water-based medium and adhere to the surface of a conductive substrate. Another common term is "electrophoretic coating," which...
In the surface treatment industry, we often hear relevant technicians mention the three words hydrophilicity, water repellency and hydrophobicity for surfaces. When we mention these terms, we think of "lotus". As we all know, when rain falls on leaves, the water does not disperse, but appears on the surface as water droplets. The main reason for...
Abrasive materials play an indispensable role in the field of surface treatment. In addition to removing the burrs of the workpiece, additives can be added to achieve a polishing effect on the workpiece. Due to the diversity of appearance and different materials of today's workpieces, a variety of shapes and compositions have been extended to meet...
Since today's requirements for metal materials are more comprehensive, if you want to improve the strength and hardness of metal, you need to use "heat treatment" to achieve it.
The electroless nickel process is quite common in Taiwan. It mainly coats raw materials with a nickel layer so that the original workpieces can have high hardness, high wear resistance, and good corrosion resistance. It is suitable for copper, iron, Aluminum, stainless steel, powder metallurgy, zinc alloy and other metal materials. After treatment,...
The same workpiece can present different effects and functions through different processes according to different needs. As shown in the picture above from right to left: aluminum alloy material, anodized treatment (black) and chemical nickel. Next, we will briefly introduce each process to let you understand.
As the name suggests, "roughening" refers to the roughening of a smooth surface through physical or chemical treatment. The most common physical treatment is the use of aluminum oxide emery grit, which is determined by the particle size and size of the emery grit. The pressure of the sandblasting equipment produces surface effects of different...
