BBOSHASI is the first auto surface treatment equipment with vaporing for PLA/ABS in the world.Direct heating method increase the risk of fire and explosion due to Flammable Vapors.Direct heating method reduces the effective processing because Vapors is not uniform contact with the product surface.BBOSHASI is safe to fire & explosion due to electromagnetic induction method.Effective swichgear structure makes vapors be a homogeneous condition in chamber to obtain smooth surface texture.Working time is very quick within 5minute and very stable.
