STEPS IN OIL MANUFACTURING PROCESS
 PROCESS CONTROL - sample collection
 Laboratory
checks are repeated in all phases of the production process in order to
guarantee that each batch meets the required characteristics.
FOAMING
 A
lubricant is destined for use in moving vehicles and must not therefore
produce foam, because this could seriously affect performance. It is therefore
important to observe the speed it takes an oil to reduce foam. This can
be done by provoking it artificially, through the insertion of small nebulous
air bubbles into the lubricant.
BOILING
 For
some products it is very important to determine their boiling point using
high precision thermometers, for brake fluids for example this is very important
because the minimum formation of gas would jeopardize the correct functioning
of braking systems.
VISCOSITY
 At
this particular stage the viscometric check must confirm the required viscosity
(SAE grade: 15W-40, 10W-40, etc.).
