Coloring process


1. Anodized aluminum: aluminum exterior, just one layer wrapped on the inner plastic.


2. Electroplating (UV): The effect is brighter than the spray image.


3. Spraying: Compared with electroplating, the color is dull.


Frosting: A layer of frosted texture.

Outer spraying of inner bottle: spraying on the outside of the inner bottle has a clear gap between the outer bottle and the outer bottle. When viewed from the side, the spray map area is small.


Inner spraying on outer bottle: Ink painting on the inside of the outer bottle looks larger from the outside. The area is small when viewed from the vertical plane. And there is no gap with the inner bottle.


4. Brushed gold and silver: It is actually a film, and you can find the gaps in the bottle through careful observation.


5. Secondary oxidation: secondary oxidation is performed on the original oxide layer, so as to achieve a pattern with a dull surface covering the glossy surface or a pattern with a glossy surface appearing on the dull surface. Mostly used for logo production.


6. Injection color: Toner is added to the raw material during product injection. The process is relatively cheap. Pearl powder can also be added, or cornstarch can be added to make the transparent color of PET become opaque (additional toner can be used for color mixing). The generation of water ripples is related to the amount of pearl powder added.


Printing process


1. Silk screen: The effect after printing has obvious concavity and convexity. Because it is a layer of ink. The silk-screened regular bottles (cylindrical type) can be printed at one time. One-time cost of other irregular pieces. Color is also a one-time fee. And it is divided into two types: self-drying ink and UV ink. Self-drying ink is easy to fall off for a long time and can be wiped off with alcohol. UV ink has obvious bumps to the touch and is difficult to wipe off.


2. Hot stamping: a thin layer of paper is stamped on it. So there is no bumpy feel of silk screen printing. And hot stamping is best not to directly on the two materials of PE and PP. Need to perform thermal transfer first and then hot stamping. Or a good bronzing paper can also be directly bronzed. Hot stamping is not allowed on aluminum plastic, hot stamping can be done at full speed.


3. Water transfer: It is an irregular printing process carried out in water. The printed lines are inconsistent. And the price is more expensive.

4. Thermal transfer: thermal transfer is mostly used for large-volume and complex printing products. It belongs to attaching a film on the surface. The price is too expensive.


5. Offset printing: mostly used for aluminum-plastic hoses and all-plastic hoses. If the offset printing is a colored tube, you must use silk screen printing, as the offset printing will show the background color. And sometimes a bright film or sub-film is attached to the surface of the hose.
