Ductile casting quality of mechanical industry influence
 Ductile casting quality for mechanical product performance has a
great influence, directly affects the precision of the pattern
in ductile castings and the mechanical performance, ductile
castings must carry on the strict quality control and
inspection, generally for ductile castings appearance quality,
faster way of judgment are available, and if the ductile casting
rough or have a slight crack on the surface of the said when the
ductile castings is unqualified product, ductile castings
internal quality check will need to use audio, ultrasonic,
X-ray, eddy current, to check the amount and judgment.
Of course, in the production of ductile casting will be some
problems in the process of casting, casting problem is mostly
after processing after pressure testing, thus causing the waste
of raw materials and energy, in order to solve the problem of
ductile casting rejection rate is high, the production will take
the most the measures that is "infiltration" impregnation means,
under certain conditions the impregnation to micro pore, ductile
castings after curing percolate into the pore of the packing and
casting pore walls in the perfect, the can wall microporous
letter, so allowing ductile castings can be full of pressure and
seepage control technology.
Prevent work
On the wall in order to avoid the above problems we will from
the production and processing time will be up to prevent work,
in order to prevent the occurrence of this phenomenon, at the
time of processing must be strictly in accordance with the
process of the process, serious and responsible do melting
casting problem, strictly enforce process discipline, makes
every effort to do it fast and smelting of quality, to strive to
achieve rapid melting, when aluminum alloy smelting. To cover
aluminum alloy with flux level, in order to prevent aluminium
alloy inspiratory, once the abnormal in the production process,
to timely and on-site technical personnel contact, take decisive
measures to deal with.
Ductile castings "electrolytic polishing"
Ductile castings "electrolytic polishing" is very important
"electrolytic polishing" can further improve the quality of
surface, the oxide can improve the corrosion resistance, so you
don't need a shock, for ductile castings, anodic oxidation was
often encountered, but have to say, the casting process of
aluminum alloy are hard to do, is very good, pure aluminum
profiles and alloy composition on this rather than itself.
