Zinc alloy processing process

1. review of mold drawings

2. mold development

3. mold T1. . .

4. Trial production in small batches

5. Technological process of mass production of

zinc alloy:

1. Die-casting blank, trimming

2. Cooling nozzle

3. Batch front treatment

4. Tapping

5. Polishing

6. Electroplating < It is more suitable for small-area laser engraving

2. Electroplating first, then laser engraving, and then laser engraving once, which is more suitable for large-area laser engraving, with high cost

2. Zinc alloy can also be mechanically drawn, with complicated process and high cost

3. Zinc alloy electroplating includes water plating and vacuum plating

1. Water plating

Advantages: wear resistance and good corrosion resistance.

Disadvantages: colors are limited to silver, light gun color and gold (gold is generally unstable)

2. Vacuum plating

Advantages: color selection is wider than water plating

Disadvantages: wear resistance and poor corrosion resistance.
