Material:

Robots for resistance welding of car body parts (plus the corresponding jigs and transport facilities)
METAL / NON METAL : steel, steel, zinc plated
Shape : No statement from company
Utilisation of equipment (throughput,workload) in % : No statement
Maximum possible throughput of parts per year : No statement
Max. area which can be cleaned per year : No statement

Dirt:

welding marks
Previous process : Resistance welding

Equipment:

Hydroblast Cycle 16-4
Mobile blast machine for CO2 dry ice pellets operated by pressed air (10 W, 4-16 bar) including a 30 ltr. container, which is filled manually from an insulated thermo container; fitted with a 10 m long hose plus nozzle; extra equipment: hose heater against blocking

Process:

Dry CO2 ice blasting

Duration of cleaning process for one part (min.) : 5.00
Duration of cleaning process for the charge (min.) : No statement
Recycling : Step:1 Since the agent is produced from waste gases, a closed loop is achieved on global level. CO2 sublimes, so only the dirt remains, which can be disposed of via municipal channels with the household-like company waste

Quality:

thin film of oil/grease tolerable/desired, Free of metallisations

Robots should weld again without problems

Subsequent process:

Continued operation/application

Costs:

Total sum : 7.416,00 EURO / Year
