Detail:

Due to the non-toxic tin plating, a large number of objects used in contact with food and beverages, the largest use is to manufacture tin cans, 

other such as kitchen utensils, food knife and fork, oven

1) Acid tin plating
advantage
1. tin is reduced by the bivalent, electricity consumption;
2. plating bath high conductivity, low bath voltage, high current efficiency;
3. operation for temperature close to room temperature, free heating equipment;

4. the use of appropriate additives can be gloss coating;
5. less damage to the substrate

2) alkaline tin plating bath
advantage
1. good uniformity;
2. a wide range of operations;
3. can tolerate more impurities;
4. simple formula;
5. no additives can be luster;

6. pretreatment requirements are not high;
7. can be used insoluble anode
