Vapor Black

Vapor Black 

PRODUCT Enquiry

 

The Vaporblack process, developed jointly by Vapormatt and Blackfast Chemicals, enables parts to be processed at room temperature employing a special chemical that is far more environmentally friendly than conventional solutions and non-hazardous to operators. Typical process time is less than 5 minutes, compared with the 45 minutes needed for traditional blacking.

 

Process Description

The process comprises wet blast pre-cleaning in the first chamber to remove surface contamination, such as heat treatment oxides and scale, followed by blacking with Blackfast 181 blacking solution in the second chamber, a water wash and then the application of a surface sealant (Blackfast 833) using dip tanks mounted to the right of the second chamber. The operation is carried out manually under preset process control parameters.

Immersion in Blackfast 181 removes minute particles of iron and steel from the component surface and replaces these with an iron copper complex, which is then oxidised (black). The surface complex produced by the process is similar to a phosphate finish but, importantly, there are no dimensional changes. The Blackfasted substrate will absorb oil / wax sealants into the component surface to give the treated parts corrosion protection.

 

Typical Applications :

  Industrial Machinery Parts.
  Cutting Tools.
  Tool Holders.
  Machine Tools.
  Clutch Drive.
  Drill Bits.
  Hydraulic Machinery.
  Hydraulic Blocks.
  Taps and Dies.
  Chains and Sprockets.
  Springs.
  Hand Tools.
  Jigs and Fixtures.
  Ball Screws.
  Fasteners.
  Gears.

 

TECHNICAL SPECIFICATION : "VAPORBLACK" MACHINES
The Vaporblack process consists of four stages :

Stage 1 : Vaporblasting and rinse in the first machine cabinet using VBM abrasive.
Stage 2 : Treatment with Blackfast 181 by spray wash in second machine cabinet (no abrasive).
Stage 3 : Fresh water dip tank at front right hand side of the Vaporblack unit.
Stage 4 : Treatment with Blackfast 833 in rear dip tank at the right hand side of the Vaporblack unit.
