A seemingly simple cosmetic packaging material actually needs several sets of different molds to be assembled after injection molding. The cost of developing a set of cosmetic molds is very high. In order to reduce the pressure on customers’ mold development, many cosmetic packaging material customization manufacturers will develop some molds that conform to the market trend. Everyone only needs to customize different surface processes and their own logo. If the purchase volume meets the requirements, the cosmetic packaging manufacturer will also customize the new mold free of charge.
1. Die Structure Assessment
If it is mold opening customization, first of all, you need to confirm the feasibility of the mold structure with the customer, then mold manufacturing-mold test-mold repair-mold modification, and confirm the sample with the customer. If the mold is mature, you only need to check whether the mold is intact.
2. injection molding processing
Injection molding processing, into mass production, is in the product injection molding in the raw materials to add toner, the process is relatively cheap, can also add bead powder, add too white powder will make PET transparent color into opaque color
3. surface coloring
This step is to color the surface of the product. These processes are available.
Alumina: Aluminum exterior, wrapped in an inner layer of plastic.
Plating (UV): Compared with the spray chart, the effect is bright.
Spraying: Compared with electroplating, the color is dark and dumb.
External spraying of inner bottle: spraying is carried out on the outside of the inner bottle. There is an obvious gap between the outer bottle and the outer bottle from the appearance, and the spray pattern area is small from the side.
Outer bottle spray: is the inner side of the outer bottle for spray painting, from the appearance of a larger area, the vertical plane view area is smaller, and there is no gap with the inner bottle.
Brushed gold and silver: it is actually a film. Careful observation can find the gap between the bottle body.
Secondary oxidation: secondary oxidation is carried out in the original oxide layer, so as to achieve the pattern of smooth surface covered with dark matte surface or the pattern of dark matte surface with smooth surface, which is mostly used for logo production.
4. custom logo, pattern
There are many ways to customize logo, such as: 3D printing, water transfer printing, thermal transfer printing, silk screen printing, electroplating, bronzing, pad printing, etc
5. assembly
Assemble all the parts together, for example, the lip gloss tube needs to be installed with the handle, lid, bottle and inner stopper.
