There are generally two methods of making polyester buttons.

Sheet

Sheet Casting button is made by a special centrifugal casting. Fully mixed Unsaturated Polyester Resin and other chemicals is poured into the rotating centrifugal drums (casting process). After sometime it will turn to be soft glue due to chemical reaction. Then cut into sheets. Put the sheets on punching machine to form different sizes of blanks. After the curing process, the state of punched blanks will turn into hard.

Sheet Casting buttons are producing by two types of Casting Drums:
Undulation Drum:
Only Pearl Imitation buttons are casted by Undulation drums to show the undulation effect.
Plain Drum:
All types of Sheet buttons are casted by Plain Drum.
There are many styles of sheet buttons, such as imitation shell buttons, pearl buttons, imitation wood buttons, multi-layer buttons, etc.

Rod

Rod Casting process of button making technology currently used by us is from Bonetti, Italy. Rod Buttons is poured by a W-shaped pipe. Pour the completely mixed Unsaturated Polyester resin, Pigments and other chemicals into the waxed aluminium tube (different sizes) through a special oscillator (casting process). When the resin become soft glue, pull out the resin stick from the aluminium tube (different sizes) and then cut it into slices (thickness wise). After the curing process, the state of sliced blanks will turn into hard.
Imitation horn button, imitation corozo button, etc., all belong to rod button.

Imitation leather button is a kind of button made of synthetic resin. Its surface has a strong sense of leather. In practical use, it is mostly used for high-end clothing. What are the characteristics of faux leather buttons?

1. Imitation leather buttons have rich colors, and the surface of common buttons has leather lines. This kind of buttons can be colored easily, and buttons of various colors can be made at will. Moreover, the smoothness of the button surface can be set according to the requirements of customers. Effects such as extra bright, matte, matte and so on can be processed.
2. The price of imitation leather buttons in the market is relatively cheap, because the production process is not different from that of plastic buttons, and the efficiency is relatively high. The overall cost is reduced, so its price is also lower, but it is still different from pure plastic buttons.
3. The product processing cycle is long. Due to the wide coating process of the imitation leather button, its production cycle is lengthened, and the general delivery time is more than half a month.
4. Because imitation leather buttons are made of synthetic resin, they are limited in heat resistance, wear resistance and resistance to organic solvents. They cannot be exposed to high temperature at will, nor can they be soaked in organic solvents, and they cannot be stirred in a washing machine for a long time. This will easily damage the shape of the button and reduce the service life.

The packaging of clothing buttons is an important process in the production process. Considering the collision in the transportation process, the packaging quality of clothing buttons is particularly valued.
In particular, the buttons of clothing with special treatment, such as paint baking, oiling, electroplating, pad printing and other processes, are easy to scratch. If necessary, the packaging processes such as film pasting and plastic sealing shall be adopted, and each product shall be isolated separately to avoid friction between products, so as to ensure that the quality of buttons will not be damaged during transportation.
