Our
commitment to quality control has led to utilization of state-of-the-art
controls throughout the production process. Examples are:
-
Sand heater/cooler keeps incoming sand at + or - 5 degrees F.
This provides high predictability of chemical binder systems.
-Microprocessor
controlled continuous mixer provides tight control of binder/catalyst
ratio in mixed sand.
-Rollover/draw
unit enables deep patterns with minimum draft to be drawn from
molds without breaking mold surface or pattern. This reduces sand
defects.
-Melting
under an argon shield prevents oxidation and slag formation in
the molten metal, thereby limiting slag defects in the castings.
-Chemical
analysis is performed with a vacuum spectrometer prior to tapping
the furnace. This ensures that metal chemistries are within specification
parameters.
-Ladles
are brought up to temperature by a computer-controlled pre-heater.
This provides consistent ladle temperature which increases heat
loss predictability in the pouring operation.
-Optimal
furnace temperatures are verified by an immersion pyrometer prior
to tapping.
-In-house
pattern shop enables rigging refinements to be made quickly and
correctly.
-Heat
treating cycles are performed by computer controlled programs
and monitored by chart recorders.
