The vast majority of marking methods damage the silicone rubber and thus weaken the material's reactive properties, or the marking is not durable, faded, rubbed off, smudged and blurred. However, laser markings processed with UV laser marking machines are able to maintain the properties of multifunctional materials and are able to process high-contrast, stable, long-lasting and biocompatible marks while retaining the properties of the material itself.
High-contrast durable markers
In these industries, the manufacture of silicone rubber products requires ultra-high decorative and informative markings. However, not every marking method for marking meets this need.
Effectively heal the needs of various industries
Inorganic silicon-oxygen substances are physically and physiologically harmless, making them suitable for medical devices.Because they are highly resistant to ozone, ultraviolet rays, and high temperatures, they are the materials of choice for the automotive and aircraft industries. And components in these industries must be able to withstand high temperatures and harsh environments. Overall, silicone rubber is stable and provides good sealing properties over the life of its use.
Marking is challenging for a long time
Long-lasting marking marks that are clearly visible and traceable and, crucially, have strong contrast.For the medical industry, the most important thing is to find a biocompatible material and a flexible processing process. Important factors for the automotive industry are heat and light resistance, as well as anti-counterfeiting and secure traceability. Find a reliable marking method to solve the current silicone rubber challenge: laser marking of fairly soft and flexible materials.
Laser marking solves existing problems
In the process of cooperation and application development, the laser marking method of ultraviolet laser marking is the process application of silicone rubber material processing marking. Laser marking marks are clean, efficient, and have strong contrast. Not only can it be easily and flexibly integrated into a wide range of production environments and systems:
- It is possible to mark anything you want on a silicone rubber device: logos, graphics, pictograms, and even images.
- Durable and tamper-proof uses, e.g. serial numbers, lot numbers, producer data and codes (1D and 2D codes, etc.).
It is important for manufacturers to use a laser marker with an integrated camera system. Ultraviolet laser marking machines are the most ideal machines for highly sensitive materials, and they are laser marking machines that can process high-contrast markings. For example, during the engraving process of silicone rubber, the surface of the product is photochemically coated with a mark.
The heat generated in this process is very low, and although the silicone rubber has been processed into a mark with strong contrast, the material itself does not change, which is important for the manufacture of parts for medical instruments, airplanes and automobiles. In addition, high-contrast markings are just as durable as liquid silicone, and UV laser marking machine-processed markings are subjected to temperatures of around 145°C when the material is used in engine bearings.
Advantages of laser marking:
→ Economical process methods
→ Simple, flexible integration
→ Clean consumables-free markings
→ Automatic calibration of devices and markers
→ Integrated imagery for control
