Application of laser engraving in medical equipment manufacturing
Laser engraving machine application in medical industry
Nowadays,laser engraving technology is popular in medical industry.
Because it brings many benefits to the medical device manufacturing industry.
Laser engraving do the most appropriate benefits for the industry.
Main marking requirement
The main requirement of medical device manufacturers for engraving systems is to :
minimize errors; trace ability ;and engraving of all types of identification.;permanent trademark.
Standards for the accuracy of engraving product content
Medical device manufacturers have strict standards for the accuracy of engraving product content (QR code, logo type, alphanumeric content) and engraving position. This standard specifies which parts of the component and device to be etched.
Engraving content can be as simple as a serial number or date, image code, graphic, company logo or trademark, or more complex, such as barcode or 2D, QR code and font type. multi-lingual.
Currently, there are many types of materials used in the health industry, and of course the engraving requirements must also be considered consistent with these types of materials. The most variable materials include.
Firstly,Metal (stainless steel, platinum, titanium, aluminum anodized, chrome-plated steel, etc.).
Secondly,Non-metallic – plastic (there are many types including PC, ABS, Delran, PEEK, HDPE, silicon and many different colors)
medical material environment requirements
The requirements for engraving on metal equipment vary,.It depends on the specific application.
However, most applications require acid corrosion protection and can withstand high alkaline cleaning methods, as well as other corrosion requirements.Such as water, steam, moisture and high temperature resistance.
Also,For non-metallic materials (plastics) that require various engravings, it typically includes the clarity requirements of the engraving content and requires engraving without damaging the internal materials. The surface of the product must be kept smooth to avoid the growth of pathogens and bacteria.
marking requirements for medical devices
In general, the marking requirements for medical devices (general materials) must include below things.
Firstly,markings must be legible.
Secondly,the durability of the markings.
Thirdly,easy traceability and anti-counterfeiting.
Benefits of carving on medical equipment
As we know,laser engraving is a popular method.
Because other methods such as inkjet printing, thermal printing, chemical printing…they are not suitable for medical implants or surgical instruments that require corrosion resistance .Because they contain permanent non-existent Chemical impurities and engravings.
Also,Most dental drilling tools, surgical instruments, tools and screws in bone grafting techniques, and other implant tools are now engraved with lasers;
Also,laser etching is a non-physical etching process that provides high quality, high precision engraving to ensure Clear, easy to read and permanent.
In addition, the use of a laser engraver does not affect the surface characteristics of the device.
For these reasons, laser engraving has increasingly become the preferred method in the manufacture of medical devices.
