Testing the Compatibility of Laser Marking and Medical Sterilization

Medical lasers have become the main option for marking surgical instruments, thanks to their high precision and resistance to sterilization.The company uses high-temperature and high-pressure testing to ensure that its labels remain legible under extreme conditions, and its products meet industry standards.When selecting equipment, you have to take into account the nature of the materials and the sterilization requirements, and also pay attention to certification and after-sales service. In daily operations, you have to pay attention to equipment maintenance and worker safety.

This is the core advantage of medical laser marking.

The medical industry requires the highest standards of precision and durability in its equipment. Laser marking machines can make markings as small as a micron on stainless steel and titanium, and they remain clear even after high-temperature sterilization.This "one-step molding, long-term retention" characteristic makes it the first choice for surgical instruments and implants.

A test of the compatibility of laser marking and sterilization.

The pre-processing and practical use of the scene are simulated.

To simulate real sterilization conditions, the samples were repeatedly treated with 134 ° C steam, to see if the edges of the markings would carbonize or fall off.Some manufacturers deliberately "up the ante" by soaking the label in an acid or alkaline solution before sterilization to ensure that the label will remain legible in extreme conditions.

The data are compared with industry standards.

The test results must be compared to standards such as ISO 15223, and focus on parameters such as depth of engraving and contrast.For example, the markings on orthopedic instruments must be at least 0.02 mm deep in order to withstand more than 20 sterilization cycles.

Suggestion from a medical equipment manufacturer.

Matching power and materials.

For example, low-power fiber lasers are needed for ceramic surgical knife handles, while orthopedic titanium plates may require UV lasers of 30W or more.Choosing the wrong type of equipment can result in poor printing, or even damage to the surface of the equipment.

Certification and after-sales service guarantees.

The first choice for equipment manufacturers is those with FDA or CE certification, which typically provide custom sterilization test reports.We once had a client neglect to follow through on after-sales service, and when the equipment broke down it stopped the entire production line.

The most important points of daily maintenance and safe operation.

After 200 hours of operation, the lenses have to be cleaned, as dust accumulation will affect the precision of the marking.When using a laser, always wear protective glasses. Even though the laser point is small, reflected light can damage the cornea.
