Barrel type wet-blasting and conversion coating equipment

BL-740-TH Overview


Tumble barrel type wet-blasting and Phosphate conversion coating equipment which has a large capacity to process, as it has a drum type barrel for continuous automatic processing of degreasing, cleaning, roughening and conversion coating to metal fittings. It is applicable for complex shaped work pieces such as a cylindrical shaped bush and mount etc. or sheet shaped work piece like metal fitting for disc brakes.


  • A tumble-barrel at the blasting part is used and therefore a whole treatment of metal fittings with effective stirring is applicable.
  • A whole process work piece on various shapes, such as complex, cylindrical and plank shapes are applicable.
  • An unique barrel drive is applied for a metal fitting transferring method in the treatment liquid tank, and it can prevent deterioration of the liquid due to mixture.
  • Processing with stable quality is applicable, since the work piece will surely be moved to the next tank at a constant speed.
