FAQ

  • Q matter or sandblasting stainless steel cutlery is same ?

    A
    Is it the same for matte or sandblasting stainless steel cutlery?
    Cool-Stainless-Steel-Knife-Set
    Is it the same level of process?
    The two methods of treating the stainless steel surface are different.
    The matt treatment method uses a matt liquid to complete the matt
    electrolysis process. Sandblasting is the use of compressed air to
    spray the abrasive toward the surface of the workpiece at a high speed.
    The purpose is to improve the surface appearance quality by removing
    the oxide layer, rust, etc. on the surface.
  • Q why Sanded-marks appear after sandblasting?

    A sanded-mark

    It is very likely that the choice of abrasive hardness is too high,
    or the size is too large, or the sandblasting pressure is too large
  • Q will the workpiece will become thicker after blasting?

    A
    Many users will worry about the thickness after the sandblasting ,in fact it is no need to worry 
    Sand blasting will remove the oxide layer on the surface; sandblasting abrasive  will not
    be attached to the surface of the workpiece, and the workpiece will not be thickened.

  • Q Why the blasting machine does not blast abrasives?

    A
    If you have problems of the sandblaster blasting abrasives, there are factors and solutions will give you some knowledge
    1. Run out of the abrasive. Turn off the air and refill the blasting abrasive.
    2. The blast gun gets block. Turn off the air and remove the nozzle to check whether there is blockages.
    3. Check whether the blasting meida is dry, because wet abrasive will cause accumulation. If wet abrasive cause this problwm, clean the gun and nozzle, discharge the abrasive, dry and seive it for resuing.
    4. The compressed air with moisture enters into the machine not only causing wet abrasives but making the blasting hose damp and stick with medias. To avoid such conditions, equipping a dryer may be better.
    5. Without sieve causing bigger dust and ununiform abrasive entering the media valve,
    6. Filling too much blasting abrasive. Over-load of abrasive will cause unpressurized.

  • Q Pressure Blast Cabinet VS Siphon Blast Cabinet

    A
    1)Working Principle:
    Siphon Type - With the compressed air flowing in the blasting gun, the siphon action will create a negative-pressurized environment that sucks the abrasive and delivers to the blast gun nozzle, which attains the purpose of abrasive blasting on the parts' surface. For the Suction blast cabinet, the compressed air is the power source of both abrasive supply and speed accelerate.
    Pressure Type - The direct pressure cabinet is specially designed with a pressurized vessel containing compressed air, which will (pneumatically)push the media to the nozzles through a media outlet valve, then blast them onto the target. The compressed air is the power source of both abrasive supply and speed accelerate.
    2)Different Features:
    Siphon Type
    A: Suitable for light blasting job and general-purpose finishing
    B: The abrasive delivery is much slower than pressure blaster
    C: Achieve abrasive travel continuously through the machine.
    Pressure Type
    A: Perfect for removing heavy coatings and conteminants
    B: The air push the abrasive 40% faster than siphon type, greatly increase the productivity.
    C: The pressure vessel needs to re-pressurize and cannot work continuously.
