A Major Manufacturer of
Anesthesia Equipment Needed a Better Magnetic Valve . . .
The solution? We developed it...
Technology that other
vendors couldn't supply was developed by EAM. Here's what we
did to provide the solution...
They had designed a magnetically controlled valve for a line
of machines that regulate the flow of anesthetic gas
delivered to each patient. Obviously, the performance of
these valves is extremely critical. They are subject to
stringent quality control inspection before being approved
for installation in the machines.
The manufacturer was installing an Alnico magnet into these
valves during the final phase of the assembly process. These
magnets would have to be absolutely uniform in strength in
order for each valve to operate properly. Unfortunately, the
strength of the magnets was inconsistent, and it was causing
over 30% of the valves tested to be rejected.
EAM personnel visited the manufacturing facility in order to
develop a more accurate and cost effective magnetic
solution.
The EAM design team determined that the assembly should be
built first, and then magnetized using in process controls —
guaranteeing that a working valve would be produced every
time. It was also decided that assembly and testing should
take place at the EAM facility so that the performance of
the valves could be monitored on site using our state of the
art statistical process control equipment.
By implementing this new technique, EAM managed to lower the
rejection rate of the valves to less than one tenth of one
percent!
In addition, EAM physically redesigned the valve itself,
developing an insert molded piece that not only improves the
effectiveness of the equipment, but also results in
significant cost savings to the customer.
