If you want to do shiny gold color, shiny gun color and shiny antique sliver color, then we suggest you to buy following metal zipper teeth coating machines:
1) Shiny gold color coating machine
There are two choices: 13 shafts vertical model and 17 shafts horizontal model. If your workshop is not that big, you can choose 13 shafts model. If there is enough space in your factory 17 shafts model is better choice, which can produce our relatively shiny gold finish.
After the zipper comes out from the shiny gold color coating machine, we suggest to put them into alkaline water tank for 2nd neutralization.(there is one neutralization tank in the machine for 1st time treatment ).
2) 9 shaft shiny gold color fixing and cleaning machine
No matter you want to coat shiny gold color or other colors, it is better to buy one set 9 shaft shiny gold color fixing and cleaning machine. Which will make the coating color last for much longer time. After the shiny gold color zipper comes out from the 2nd alkaline water tank, it can be put directly into this machine. The workflow is: shiny gold coating--->alkaline water immersion--->color fixing and cleaning machine--->lacquering machine.
If you need to coat other colors after shiny gold(for example, shiny gun color), then the zipper should goes to another machine after coming out from the 2nd alkaline water tank. The workflow is: shiny gold coating--->alkaline water immersion--->shiny gun color coating--->color fixing and cleaning machine--->lacquering machine.
If you want to coat shiny gun color, then 19 shaft black nickel(common gun color) coating machine(Single color coating machine) is suitable option. This machine can do gun color, antique brass, shiny nickel and light gold. If you mainly do gun color and antique brass color, and only do shiny nickel or light gold occasionally, then you can only buy one machine. However if you have many orders for both dark color and light color, we suggest you to buy two machines. One set for gun color and antique brass color and the other machine for shiny nickel and light gold. As you know the coating formulas are totally different for the light colors and dark colors. If the tanks are not cleaned thoroughly after light color coating, the finish will not be pure when you do the dark color production.
Notes:
a) Shiny gold color coating is the very first step before doing shiny gun color, shiny antique brass color, shiny nickel color and light gold color.
b) Shinny gun color and black nickel color difference: shinny gun color is usually done by SEO2, and black nickel is done by stink ammonia water. Most factories are doing the shinny gun colors now.
