The characteristic of alloy steel casting is similar to that of Carbon Steel Casting and cast steel containing alloy elements such as manganese, chromium, and copper is a cast alloy steel. China Alloy Steel Precision Casting is also called lost wax casting, or China Alloy Steel Investment Casting . Casting products are precise, complex, and close to the final shape of the parts, which can be used without processing or with little processing, so It is an advanced technology.
In wax pattern process,we mix stearic acid and paraffin wax in wax pattern making,as you know,it is better than polyethylene,and the wax deformation is small.
In
shell making,we adopt automatic sand-covering production line, which was
invented under the guidance of our general manager.The indoor temperature was
controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more
stable,the internal tissues much more well-proportioned.
In
shell hardening process,we use aluminium chloride to harden the shell.This can
make the shell so hard that it can`t be distorted,at the same time the bug
which the casting may have will be decreased.If there are letters or numbers in
it,they will be much clearer.
In
dewaxing process,about 95% of the castings suppliers adopt the original water dewaxing
technics,but we using the advanced steam dewaxing technics,which we are very
proud of.This can effectively avoid the air-hole and sand-hole,making the
casting look much nicer.
In
smelt process,we use middle frequency furnace,avoiding the emergence of the
oxide; in molten steel control part,we use Germany-imported direct reading spectrometer
machine,assuring its quality before the molten steel out of the furnace.During
this process we use ERP production and management software to get the feedback
information.
In
shell-knock out process,we have special machines,which can decrease the hitting
and knocking, easily made by manual shell knocking out.
In shot-blasting
process,we have crawler-type and hanging shot-blasting machine,with steel shot
0.5-0.8,making the products smooth.Of course,if the customer wants it look much
nicer,we also can carry out sand-blast treatment.
In
heat treatment process,we use electric furnace,and adopt double-temperature
control in order to heat the products equally.As a result, the products will
have great metallurgical structure.
Our
tolerance can reach at the grade of 5-7 according to our country`s tolerance
standard.
In machining process,we have 12 CNC machining centers
and some other machines, so we can make further machining if the customers need.
Products in alloy steel cast factory divide into Forklift Parts Investment Casting, Agricultural Machinery Parts Investment Casting, Petroleum Parts Investment Casting, and Chemical Parts Investment Casting.
