Process:
Pre-degreasing degreasing → → → cold hot water washing → pickling → → in cold water and cold water → surface adjustment → phosphate → cold water hot water → → → Rider Pallet Truck pure water and dried
The above process may also make appropriate adjustments based on oil, rust sheet metal stampings situation, with or without pickling process, with or without pre-degreasing. The degreasing and phosphate chemical treatment process is a key step, the two processes directly affect the quality of the workpiece quality chemically treated and rust coating. Electric Hand Pallet Jacks Relevant process parameters and related auxiliary equipment also affect the quality of surface __ reason can not be ignored.
