Microtech Private Limited is manufacturing electrical
panels to meet the toughest quality standards and
are subject to rigorous manufacturing processes that
are as follows:
CPRI Test Certificate at 50KA for 1 sec
- ISO 9001 under implementation stage
Sheet metal and Painting:
metal parts are purchased from steel authority of
India and checked for the thickness at the time of
buying. Loading and unloading of the sheets are done
in strict supervision of HMPL employee to ensure that
no damage is to sheet while it is in transportation.
the Panel is fabricated as per the approved drawing,
it is subject to either Seven tank process or Sand
blasting Process to make the sheet metal free from
rusting, greasing. During seven tank process, hot
phosphating is done.
the sheet metal is through to above process, the two
coats of Zinc rich primers are applied on the Panel.
After applying two coats of Primer, the sheet metal
parts are washed and then fine finishing is given
to it by grinding paper. Putty is used to feel up
the patches and then Epoxy based surfacer is coated
on the Panel. After applying surfacer, that is kept
for drying. Once the drying is done, the paint ( as
per customer's specifications such as PU, epoxy )
is applied on the sheet metal for two times.
the paint is done the quality team inspect the paint
quality and then give their decision for the panel
the incoming material are checked for the manufacturing
defects and functional test. Wherever required H V
test is performed on the individual component. Once
this components are checked they are tagged for OK
or rejected part. The rejected part is kept in separate
rack and OK material is sent in the store.
the sheet metal enclosure is ready assembly is done
as per the drawing. When the panel is ready the outgoing
quality control on the panel will be done. In this,
mainly H V test and megger test is performed on the
panel along with functional test for specific requirement
and interlock, if any. Based on the test result, the
panel is sent to the customer when the same is OK.
