Laser technology is considered as a precise and fast method in processing material and becoming more essential in the field of medical & dentist instruments manufacturing.

Laser markers are used in the pharmaceutical, cosmetics & medical industry to apply identification marks, tracking data, and expiration date information to products and packaging. Such verification is, in particular, intended to reduce the globally increasing fraction of low-grade product copies.

1. Laser Marking

1.1. Marking on product packings

  • The information is chiefly barcodes, expiry days, others on drugs & cosmetics marked on different packings such as paper, plastic, etc

  • Or directly mark on product packings

1.2. Carved capsules

Tablets in the past are often printed with ink, which has many disadvantages such as easy to smudge, easy to erase and use of chemical solvents (ink), so it is difficult to ensure the health of the patient.

Meanwhile, the application of UV laser technology allows:

  • High-speed engraving, however, still maintains a smooth engraving effect, engraves very small details without damaging the shell surface.
  • Save costs for manufacturers by not using too many consumables for machine replacement and maintenance.
  • High flexibility: has the ability to change the marking without having to change the printing roller (ink printing method).
  • Serial numbering can be changed continuously and customized for each engraving or even by pill during the engraving line thanks to the ability to save stock files.

1.3. Anti-counterfeiting

The marks engraved by laser marking technology can not be forged or changed easily with strong anti-counterfeiting to certain extent. Thanks to the ability to handle flexibility, the UV laser can engrave text, logo, series number (traceability needs) or barcode / barcode (anti-counterfeiting application), ... onto the capsule and give It is possible to change the etching pattern per batch or per pill.

1.4. Marking on medical equipment

Laser is a technology to meet the requirements of marking on medial equipment. As other methods such as inkjet printing, thermal printing, chemical printing... are not suitable for medical implants or surgical tools that require corrosion resistance because of Contains chemical impurities and imprints that do not exist permanently.

Most dental drills, surgical instruments, tools and screws in bone transplantation and other implants are now laser engraved; laser marking is a non-physical contact marking process that provides high-quality, high-precision engravings that ensure clarity, legibility, and permanent existence. In addition, using a laser marking machine does not affect the surface properties of the device.

1.5. Trace and Track medical equipment

Medical equipments must be etched to properly trace and be trackable throughout the life of the device to improve patient safety, simplify product recall and optimize visual market.

2. Laser Engraving

2.1. Laser engraving in the medical (health) & dentistry

Most of instruments used in the heath and dentistry are always required highest quality. Therefore, laser technology is consider as a precise and fast method in processing material and becoming more essential in the field of medical & dentist instruments manufacturing. The reasons that laser technology can bring many benefits to this sector are the capabilities of cleaning and effectively removing debris and dirt on surface of materials. 

Additionally, laser engraving systems can also make details on products with high reliability and quality that can be used in all environmental conditions without any damage. Laser engraving in the medical (health) & dentistry has become popular in today's technological era due to the fact that there are so many manufacturers supply hospitals or medical centers with a wide range of devices or instruments for different purposes. 

Therefore, they must be shown clear origin and supported with manuals to prevent and handle with arising risks. In case of occurring unexpected incidents relating to the instruments, medical experts can easily identify their origin as quickly as possible to handle the incidents.

2.2. Permanent marking on medical equipment

Be suitable for medical devices processing because of its ability of permanent marking on metal and plastic materials. Often used to replace for other methods such as metal dot marking, corrosion, embossment, etc due to the advantages of clean, stable, digital and affordable proces.

3. Laser Cutting

3.1. Stent cutting

Laser cutting of very thin-walled tubes has developed rapidly in line with demands from the medical device industry. It is possible to Laser cut extremely complex shapes in 2 mm OD tubes with walls as thin as 0.2 mm. This application has placed severe demands on the conventional Lasers used. This Application Insight looks at the cutting of stents with lasers exploring both stainless steel and nitinol stents and examines the benefits of lasers and the advantages over other alternative technologies within the medical industry.

The average power required for these small scale tube cutting applications is in most cases relatively low, with most stainless steel stents typically being cut with 200-500W rated Fiber Lasers, with higher power levels needed only for nitinol. Certain specialist manufacturers now offer fully integrated Laser cutting systems/machines commercially fitted or retro-fitted with our Lasers. These systems/machines provide the sophisticated clamping and high accuracy multi-axis movement required for precision cutting of a range of different medical device materials.

3.2. Laser Cutting in the Medical Sector

The medical sector is one of the most vital sectors around the world and is one industry where it is perhaps more imperative than most that the processes from beginning to end-run smoothly.

Laser cutting is most often utilised in this industry for the creation of medical devices; devices which can be extremely small. Furthermore, these devices will be used to save lives, so their quality and reliability need to be assured from the start.

3.3. Creating medical devices

One of the most vital uses in is to create or laser cut medical devices. An example is the cutting of high-grade stents, devices which are used for things such as birth control or controlling kidney stone pain.

3.4. Precision tube cutting

Cutting with lasers enables precision tubes to be cut; items which are extremely popular within the sector.

3.5. Laser surgery

We explained above how cutting can be used on skin and human tissue, and this is because a cut can be made quickly, cleanly and precisely, without causing heat damage to the surrounding area.

Laser surgery is a better alternative to more conventional methods, such as using a scalpel, and you’ll often find laser surgery being used for processes such as eye surgery.
