(1) iron and steel parts electroplating process


┌ Acidic galvanized
Degreasing → rust → │ → → → drying
└ Alkaline galvanized


(2) steel parts at room temperature black process
┌ Extreme water anti - rust oil
│
│ drying
Degreasing → rust → room temperature black → │ dip soap - → dip spindle oil or oil
│
│
└ immersion sealant


(3) steel phosphating process: degreasing → rust → → → → → → coating


(4) ABS / PC plastic plating process
Degreasing → hydrophilic → pre-coarsening (PC≥50%) → coarsening → neutralizing → finishing → activating → debinding → chemical ninking nickel → coking copper → copper plating → plating semi-bright nickel → high sulfur Nickel → plated nickel → plated → chrome plated


(5) PCB plating process
Degreasing → coarsening → prepreg → activating → debinding → chemical copper → copper → acid degreasing → micro-corrosion → plating low stress nickel → plating nickel → gold plating → drying


(6) multi-layer steel plating process
Degreasing → rust → copper plating copper → copper plating → plated semi-bright nickel → plated high sulfur nickel → plated nickel → nickel seal → chrome


(7) steel parts pre-treatment process
1, grinding parts → in addition to wax → hot dip oil → electrolytic degreasing → acid corrosion → non-its plating
2, non-abrasive parts → hot dip oil → electrolytic degreasing → acid corrosion → other plating


(8) zinc alloy plating pre-treatment process
In addition to wax → hot oil removal → electrolytic degreasing → acid corrosion → copper plating copper → copper or copper phosphate → other plating
