How chemical etching process work
This process is done in different steps, sheet sizing, tooling, cooling and photo-resist lamination and stripping. In this etching process the material that is desired is laminated with a resist that is photosensitive and then exposed to a UV light to get the products image. The product obtained from exposing the substrate to a solution that removes the unprotected parts of it. These steps should be done carefully to achieve better results.
Advantage of chemical etching
Many chemically tested tools has advantages like dying and cutting. This gives the flexibility and cheap designs. The compression process does not cause mechanical stress on the material, leaving particles and tensions unchanged in the material structure or magnetic properties.act that the same process route is used to prototypes as is used to produce volume quantities.
Applications of chemical etching in hospitals
Stainless steel used in hospitals is made of nickel,chromium and molybdenum metals that gives a even finish ,corrosion resistant and a metal that increases the hardness to sustain the cutting edge simultaneously. Cobalt-Chromium due to its resistance to wear and corrosion it is applied in orthopedic implants.
Nickel titanium has two unique properties that is shape memory and super-elasticity characteristics. These properties have made the medical innovation possible.
Most metal can be chemically etched as long as the right equipment are used. The raw material for etching vary differently in price. Stainless steel, brass, copper, bronze, aluminum, titanium, nitinol, molybdenum, zinc, nickel, silver, gold, magnesium, Silver, nickel, Phosphorous bronze, Beryllium copper, Mu Metal all can be chemically etched. Silver and brass are cheaper than nickel titanium.
Titanium-due to its ability to resist corrosion, biocompatibility and the ability to knit with human bones, it has become a basic material in the medical field. has become a fundamental material used in medicine. Titanium and its alloys are used in a variety of implant applications, including bone and joint replacement, maxillofacial and craniofacial treatments, and cardiovascular devices, as well as for external prostheses, and surgical instruments.
Chemical etching does not need heavy equipment like laser cuts because of the improvisation of heat loss.
Other advantages are: Repeat for higher production, Great flexibility in design, and inexpensive equipment, Asymmetrical and compact parts, The physical characteristics and grain structure remain unchanged, Strict durability is capable of producing components with complex geometry.
Another major benefit of producing medical parts by chemical etching lies in the fact that the same process route is used to prototypes as is used to produce volume quantities.
