In the cosmetic packaging industry, often can see the metal texture of the packaging, in addition to the original metal material, is through the spray plating treatment. Because of environmental protection factors, many spraying factories have been closed or rectified recently. However, vacuum coating has become a new trend of environmental protection in the plating industry because of its safer, more energy efficient, lower noise and less pollution emissions. Today let’s walk into this process together.
Basic knowledge of vacuum electroplating:
What is vacuum plating?
The process is in vacuum conditions, the use of low voltage, high current way to heat the steam source, the target in the case of power heating dispersed to the surface of the workpiece, and in the shape of amorphous or liquid deposition on the surface of the workpiece, cooling film process. Because the coating machine evaporates the target in the vacuum state to generate the coating, this process is called vacuum electroplating.
Vacuum plating process:
Step1: Pre-treatment. The pre-treatment process of different products is different, such as the pre-treatment process of powder powder box spraying is to sand the accessories before to prevent the spray of powder box teeth. After sanding, the parts also need to be wiped to prevent dust on the surface of the product after sanding.
Step2: Install the fixture on the line. The fixture should generally be installed in the middle of the product (so the general sprayed product will have the fixture print, but it will usually be covered by a mirror or aluminum plate), ready to be installed after the line.
Step3: double dust removal. First, spray the surface of the product with environmentally friendly cleaner, and then wipe it with a dry cloth after treatment.
Step4: automatic static electric dust removal. After the second dust removal, it is also necessary to carry out electrostatic dust removal treatment to prevent the surface of the product with static electricity, adsorbing dust and hair.
Step5: Automatic spraying of electroplating primer. After electrostatic treatment of the product, it is necessary to spray a layer of electroplating primer, after spraying the electroplating primer, it is necessary to pass the UV lamp, and then install the product on the electroplating rod.
Step6: Start electroplating. The products that come out after electroplating are bright silver mirror effect.
Step7: Color spray. The electroplated products also need to be colored according to the needs of customers, and then the line is sprayed after color mixing. (After spraying, it should be cured and dried by UV lamp)
Step8: offline full inspection. After electroplating and painting, the product can be finished, that is, the electroplating process is completed. After the next part of the product needs to go through a full inspection, and then install the standard packaging.
Advantages and effects of vacuum electroplating
Advantages of vacuum plating:
1. Protective effect. Protect the surface of the product from light, rain, dew, hydration and various media erosion. Using paint to cover the object is one of the most convenient and reliable protection methods, which can protect the object and extend its service life.
2. Decorative role. Coating can make the object “put on” a beautiful coat, with luster, luster and smoothness, and the beautified environment and objects make people feel beautiful and comfortable.
3. Special function. After painting the special coating on the object, the surface of the object can be fireproof, waterproof, antifouling, temperature indication, heat preservation, stealth, conductive, insecticidal, bactericidal, luminous and reflective functions.
The common effects of vacuum coating:
Can do solid color (bright or matte), gradient, seven color, magic color, special texture (such as flower spots, raindrops, ice cracks, etc.) and other effects.
The detection method of vacuum electroplating products
1. Product cleaning: the visible surface parts inside and outside the product should be clean, no stains, oil stains and other dirt affecting the appearance, and no white marks left after the hand is allowed.
2. Product appearance: Check whether the product has wrinkling, shrinkage, foaming, whitening, orange peel, vertical flow, particles and other undesirable phenomena.
3. Characteristic check: According to the standard color plate check spraying color difference (color difference meter), film thickness (film thickness meter), gloss.
