Our Capabilites

Manufacturing Processes

Fabrication
Carbon, SS and aluminum with material thickness up to 1.5 inches in thickness.  Press brake forming /bending-Plasma burning to produce single components or complete assemblies

Materials
Vista International has the ability to produce components in a wide range of ferrous and non ferrous materials including low carbon and high alloy steels, aluminum brass, nylon and plastics

Castings
We have the ability to produce most all metal types using the
following process or medium sand, shell mold, squeezer, disa-matic,
die casting, permanent mold and investment casting

Permanet Mold Castings
While not as flexible as sand castings in allowing the use of different patterns (different part designs), lower the cost of producing a part. At a production
run of 1000 or more parts, permanent mold castings produce a lower piece
cost part. Of course, the break-even point depends on the complexity of
the part. More complex parts being favored by the use of permanent molds.

Die-Casting
Similar to permanent mold casting except that the metal is injected into the mold under high pressure of 10-210Mpa (1,450-30,500) psi . This results in a more uniform part, generally good surface finish and good dimensional accuracy, as good as 0.2 % of casting dimension. For many parts, post-machining can be totally eliminated, or very light machining may be required to bring dimensions to size.

Die-casting can be done using a cold chamber or hot chamber process.

Sand Casting
is used to make large parts (typically Iron, but also Bronze, Brass, Aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic).

Investment Casting
All alloys from low carbon to
stainless, lost wax and silicon lost wax
(more information)

Shell Molding
process offers better surface finish, better dimensional tolerances, and higher throughput due to reduced cycle times. A heated (200 ?C / 392 ?F) metal pattern is covered with a mixture of sand and thermoset plastic. This causes
a skin of about 3.5 mm (0.125 in) of sand/plastic mixture to adhere to the pattern. This skin is removed from the pattern to form the "shell mold".
The two halves of the shell mold are secured together and the metal is
poured in the shell to form the part. Once the metal solidifies, the shell is broken.
