Zinc parts surface treatments have diverty types of surface finishes, include of painting, powder-coating, black nickel plating, chrome-plated, Ec-coating, shot blasting and mirror polishing etc. Depends on the functional and aesthetics of parts, they accept different surface finishing options. Zinc parts are so easy to be coated by luxurious metal and become more attractive and glossy due to the specific metal has a strong bonding attribute for color metal material. This makes zinc parts surface treatments diversity.
Which Types Are For Zinc Parts Surface Treatments ?
Zinc parts require more luxurious decoration to meet functional and aesthetics of them, they will have various types of surface treatments.They maybe involves of the below common surface finishes for zinc die castings in modern industrial metal parts manufacturing.
Polishing
The die casting part polishing process is indispensable in treating the surface of metal casting parts. Such as glossy, mirror-reflective surface, satin surface. The polishing effection is decided by the requirements of the surface finish. Like precision electric components, decorative parts, consumer products need different polishing effections.
Shot Blasting
Shot blasting or bead blasting hit on the metal parts in high power. These small particles generate a uniform hitting on the surface of parts. The process can remove some hidden and tinny burrs on the cast parts in high efficiency, remain the cast parts more smooth surface. It is suitable for industrial equipment, non-decorative housings, and outdoor applications.
Nickel-Plated
Zinc parts can be plated with bright nickel to enhance the parts appearance glossy, people can choose satin nickel or bright nickel effections. The common plating can make these zinc die casting parts more durable and aethetic stylish. The bright metal coating layer can protect the surface of these parts, withstand the aid substance corrosion and prevent metal part surface further oxidation. and enhances wear resistance of these parts. Like some fashion accessories, zipper headers, jwelleries and decorative trims.
Chrome-Plated
Zinc parts chrome-plated can enhance corrosion resistance, wear resistance, or aesthetics. The treatment process is super surface finish level process method for zinc parts, striking copper, coating nickel, then plating chrome on the surface of metal casting parts. These zinc parts with chrome-plated accept water rinsing and neutralization. These surface finish material is expensive, but the effection is best. Die casting parts electroplating can create a metallic look (e.g., chrome-plated). Like consumer goods, automotive parts, and appliances components are all plated in real life.
Electro-Coating
Electro-Coating is high-perfermance metal coating process, which deposit the paint on the surface of metal part with electric current, aim to decorate and protect the surface of the part well. Zinc parts, especially zinc die casting parts requires aesthetic and durable appearance, such as consumption electrical goods enclosures, automotive internal components and fashion accessories. Various color electro-coating painted zinc parts become more and more popular.
Power-Coated
Powder coating finish means coating a layer of thermal melt paint or polymer powder on the surface of metal part. As Metal Casting Parts Coating, The thermal melt material spray evenly on the surface of cast parts with spraying gun, then deliver the metal parts into oven, makes the themal melt material deposition on the suface of the cast parts, generate a thin, durable protective finish.
Texure Or Pattern
Marking specific textured or patterned surface on it directly during the casting process. Text finish is very common surface finish, Stamping texure and pattern on surface of the core of the mold. Of course our laser marking on zinc die castings can mark brand logos and patterns on the part, For zinc die castings, We can select the right laser marking enquiqment to engrave custom logos and brand patterns on the surface of custom metal parts. CO2 Laser is typically used for both non-metal materials and metal materials. More can be used with certain coatings on zinc parts.
Zinc Parts Surface Treatments Advantages
Zinc Parts surface treatments impove not only the aethetic appearance of metal parts but also enhance their durability. With some specific surface treatments, make zinc parts specific functions in some professional occasions. These obvious advantages take into the sight on the blew key points.
Enchanced Zinc Parts Corrosion Resitance
zinc parts surface treatments enhance a thin protectional layer for the zinc parts, makes them endure aid corrosion and high salt content air corrosion. Especially these zinc parts used in some hash environment and worse weather, prolong their life time. Depends on the requirements of functions and application environment, these zinc parts can have specific surface treaments and meet diverty demands in many industrial fields.
Improved Zinc Parts Appearance Aesthetics
Some zinc parts require gloss and mirron-flection effection or bright smooth effection, such as jwelleries, gifts and automotive interial components. These metal parts requires mutil- processes surface treatments, reach bright, gloss and mirror-flection aethetic appearance. So these specific treatments, which include of e-coating, chrome-plating, powder-coating and texture finish can create aethetic and luxurious appearance effections.
Extend The Life Time Of Zinc Parts
Zinc parts surface treatments enhance a thin protectional layer for the zinc parts, makes them endure aid corrosion and high salt content air corrosion. Especially these zinc parts used in some hash environment and worse weather, prolong their life time. The zinc parts are more durable when they have a lay of thin protective film on the surface, natually their life time is extended.
Increased The Zinc Parts Wear Resistance
These surface treatment material is bonded on the surface of zinc parts, and not easy to peel when they are uesed times. So these c parts become more wear resistance after surface treatment. Instance for more consumer electrical goods housings and enclosures, fashion accessories and zipper headers, and remain bright and attactive appearance for long time. Some luxurious gifts and automotive interial components are chrome-plated, makes them more wear resistance than nickel-plating surface finish, because the copper stiking coating is high hardness copper bonding material, so they are more wear resistance.
Meet Some Specific Functionalities Of Zinc Parts
Some small sizes oof zinc parts are used for communication and electrics, and require high-perfermance electrical conductivity, So they maybe accept silver, gold and copper bonding material adhered on the surface of them. These specific surface treatments can add some specific functionalities of zinc parts.
Conclusion
In summary, zinc parts surface treatments are diversity, from the initial polishing to multi-processes chrome-plating, aim to creast high performance protective thin layer on the surface of zinc parts. These make the zinc parts more durable and improved parts appearance. Of course expert suggest stongly that choose more professional treatment finishing supplier to product high quality zinc parts to meet the requirements across many industries.
