Powder Coating
Powder coating, a dry surface finishing process used on a variety of surfaces, primarily metals. With finely ground particles of pigment and resin, then cured under heat to form a hard, durable layer for the purpose of protective and decorative.
The curing process of powder coating is a key step to ensure the quality and performance of the coating, and requires precise control of temperature and time to achieve the best coating effect.
Parts after powder coating will become harder, more durable, more uniform and have good protective properties.
Available Materials for Powder Coating
High machinability and ductility. Aluminum alloys have good strength-to-weight ratio, high thermal and electrical conductivity, low density and natural corrosion resistance.
Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed.
Titanium is an advanced material with excellent corrosion resistance, biocompatibility, and strength-to-weight characteristics. This unique range of properties makes it an ideal choice for many of the engineering challenges faced by the medical, energy, chemical processing, and aerospace industries.
Iron is an indispensable metal in the industrial sector. Iron is alloyed with a small amount of carbon – steel, which is not easily demagnetized after magnetization and is an excellent hard magnetic material, as well as an important industrial material, and is also used as the main raw material for artificial magnetism.
Steel is a strong, versatile, and durable alloy of iron and carbon. Steel is strong and durable. High tensile strength, corrosion resistance heat and fire resistance, easily molded and formed. Its applications range from construction materials and structural components to automotive and aerospace components.
Stainless steel alloys have high strength, ductility, wear and corrosion resistance. They can be easily welded, machined and polished. The hardness and the cost of stainless steel is higher than that of aluminum alloy.
Highly resistant to seawater corrosion. The material’s mechanical properties are inferior to many other machinable metals, making it best for low-stress components produced by CNC machining.
Brass is mechanically stronger and lower-friction metal properties make CNC machining brass ideal for mechanical applications that also require corrosion resistance such as those encountered in the marine industry.
Few metals have the electric conductivity that copper has when it comes to CNC milling materials. The material’s high corrosion resistance aids in preventing rust, and its thermal conductivity features facilitate CNC machining shaping.
Design Considerations
- It is recommended to plug and mask threaded or reamed holes or other critical-to-function surfaces during this process.
- In general, powder coating polymers are insulative and do not conduct electricity well. For applications requiring electrical insulation, the coating must have the appropriate dielectric properties.
- Consider the color, texture, and finish of the coating to meet aesthetic requirements.
- If the coating will be exposed to outdoor conditions, it must be resistant to UV rays, moisture, and temperature changes.
