porosity into  chrome Surface

finish , thus  pioneering  the 

words  Porous Chroming

Industry.Today,this process

is  not  just  our 

Basic activity - it  is

our strength .

Electrodeposited  chromium 

is extremely hard  and

has non-stick and very

low wetability properties.

Whilst these enable  chromium

to remain  free of contaminent ,

they also render it almost

impossible to lubricate.

The bonding between the

parent  metal and chrome

in a  word   is   perfect  .

Two  factors  affect   the 

bonding ,mechanical

pre-treatment  of  the 

parent  metal and its electro

chemical preparation . 

By  creating  porosity  on  this 

 surface  by   our  patented

Porous  Krome  Plating,  we

have  gone   further   and

ensured   sufficient    oil 

retention   by    inducing  

minute surface  reservoirs.

These Porous Krome plating

techniques are widely used

by   us   to   recondition   a 

variety    of    components 

such  as Diesel    Engine 

Liners ,Crankshafts,Piston

Rods ,Hydaulic Cylinders 

etc. list

is  increasing  rapidly.
