Regarding the surface identification of
surgical instruments, due to the need for surgical identification, designers
will make a variety of identification lines on the surface of implanted
interventional instruments. Recently, I chatted with some friends and said that
some of their stainless steel products had a slight yellowing problem in the
logo link. They asked me if there was a problem with the material. Later, after
understanding, it was found that there was a problem with the selection of the
logo process. Well, we are establishing a logo When the standard requires, what
issues need to be paid attention to?
Nowadays, the popular design marking
process options are all laser markings. Indeed, the laser-made markings belong
to a high-temperature sintering process, which causes the surface to become
black. Then even if you choose stainless steel. After laser processing, if the
treatment is not good, there will be secondary oxidation possible afterwards,
which is the rust phenomenon that everyone often appears. JY Machinery team
generally recommends that when choosing this laser marking process, we must
force the chemical protection of the sintering position to improve its
corrosion resistance.
In fact, for the marking process, many of
the foreign surgical instrument process choices are corrosion processes. After
being energized through the chemical solution, the color difference reaction
occurs on the surface to achieve the black reaction. For this situation, JY
Machinery team conducted a series of Experiments and demonstrations show that
the corrosion resistance of this process is better than the effect of laser
surface recognition, and the test is not a problem for more than 75 hours, and
then it can pass the biosensitivity test smoothly. So the question is coming,
why do many designers prefer laser marking? Some investigations have also been
done in this regard, and they all agree that the advantage of the laser effect
is that the edge of the mark is better than the erosion.
For the process selection of surface
recognition, what should be paid attention to? Laser marking is carefully
selected for carbon steel material devices, implanted devices, and products
that require "biocompatible" test products. Based on the safety
considerations, JY Machinery recommends that you choose a corrosion process to
ensure surface stability and avoid some. Security threats. In addition, we also
need to do a good job of secondary contact and cross-influence risks in surface
chemical protection and clean circulation.
