EPMS V/S HRPO
"Valgro EPMS Process V/S Acid Pickling Process"
Features |
Valgro-Fynex EPMS (ECO PICKLED METAL SURFACE) process |
Acid Pickling process |
Shot / slurry blasting Process |
Consumables | Valgro EPMS (ECO PICKLED METAL SURFACE) process does not used hazardous chemical | Acid used in acid bath of the sheet metal is corrosive | Send or mineral used with Air Shot / water |
Work environment | Eco friendly work environment | Acid fumes damaging the Building, equipment, people, land etc. | Dusty work environment |
Disposal restrictions | No Disposal restrictions, mental peace from pollution control board | Used hazardous chemical require special storage and disposal restrictions from PCB. | Require approval from pollution control board (PCB) |
work station | 20% floor space require against traditional process. | Large space require (500 feet) | Large size of blast chamber and dust collection system require |
Line stoppage | No side effect on surface during line stoppage | Over pickling damage sheet surface, Rinse stain, metal lose, dimples | |
Line speed | Faster than Acid pickling process | Low running speed | Lower production speed |
Life of the consumable | Longer brush Life for surfacing operation | Frequent replacement require acid chemical and fresh water | Maximum 1 or 2 time used |
Surfacing benefits | Delayed oxide formation 30 to 90 days rust free warrantee | Oxide & Rust generated very fast on pickling process due to corrosive chemical | Surface hardness increase in shot blasting process |
Surface cleaning quality | Consistence surface cleaning 1st meter to last running meters for batter coating printing operation | Due to historical problems no proper adhesion for coating & Printing on unclean surface | Occasional embedded shot into carbon substrate is not acceptable to customer |
Productivity | Increasing the Productivity : reduce historical problems with increase surface value | Non Productive Work : Oil patch, oxide layer, rust surface, depth oxide, un-pickled patch, mill scaled, black spot not clean perfectly | |
maintenance & Consumable cost | Lower maintenance cost. Very Economical Consumable | Higher maintenance cost, require frequent replacement of Acid pump and other component | Expensive Consumable, Impeller, Blade set, Housing Liner, and other rotating parts replacement twice in month |
Metal Loss | No / Negligible Metal Loss (0.5% metal loss) | 1% to 2% Metal Loss During the pickling Process | |
Inventory & storage | Can be store at your regular store department with lower space | Required special and large storage tank space for fresh & Used chemical | Required special and large storage space for fresh & Used chemical |
Labors | Faster production in minimum men power | Required number of labor in pickling process | |
One stop solution | Technological support for abrasives brush and brushing machine for batter surfacing from Valgro India | Require two different type of experts for both object | |
Break even points | Very fast break event achieve, compensate with floor space of land, with in 6 to 12 month | Land is very expensive and acid pickling process require large area of land |
