Laser marking plastic technology has become commonplace in industrial equipment, medical devices, aerospace components, auto parts and general household appliances. However, medical device manufacturing (MDM) suppliers are required to track their products using unique device identification (UDI) codes, data matrices, and other tracking information. They must also meet strict Food and Drug Administration (FDA) and GS1 guidelines. In the event of a rare failure or other adverse event, tracking where and when a product was manufactured can go a long way in identifying the problem and taking action to prevent it from recurring.

 

Today, let's talk about UV laser marking plastic bottle cap technology according to UDI GS1

 

"Cold Marking" with UV laser provides smooth marks within the surface

When laser marking plastics, the first thing to consider is the type of mark you want. Methods range from surface melting or foaming, to photochemical changes to materials using UV and green lasers. For medical grade plastics, UDI markings must feel smooth and eliminate areas that could harbor bacteria. This is where "cold marking" at UV wavelengths comes into play. The use of UV lasers during cold laser marking changes the molecular structure of the material, which is ideal for applications sensitive to thermal damage. This thermal damage outside the marked area is called the heat affected zone (HAZ). Additives in white plastics, such as TiO2, strongly absorb UV light and undergo chemical changes in the plastic, making it darker. This process produces smooth, highly legible marks inside the plastic, not just on the surface.

 

For plastic surface marking, the RFH classic S9 UV laser is highly recommended.

 

According to the needs of market development, the newly launched S9 series laser split machine of Shenzhen RFH Laser Technology Co., Ltd. includes water-cooled and air-cooled. Compared with products of the same type, the S9 series is smaller in size, more refined in design, and more stable in light output. The small and compact design means that users do not need to make a large optical path, which can greatly reduce costs and save space, and can be easily installed in the field of flying marking equipment. The S9 UV laser is not only small in size, but also has a more stable cavity structure and stronger expansibility than similar products. The same cavity can generate lasers of various powers, and the stability of different power segments is greatly improved

RFH 355nm UV laser can cut screen protector tempered glass film with smooth and even cutting edges   With touch screen being increasingly used, the demand of mobile phone tempered glass film is also increasing. However, the sizes of different mobile phone brands are different, so the tempered glass film needs to be cut and drilled to required size. In the past, people used traditional CNC cutting technique on tempered glass film, but this method can easily lead to micro cracks or broken edges. So how to prevent tempered glass film from damaging during the cutting process? Well, RFH UV laser can help. The tempered glass film using RFH 355 series UV laser to drill and cut on won’t damage because of heat or crack because of instability. Instead, its cutting edges are quite smooth and the drilled holes are very round, making it more suitable to be used in smart phones.
