UV laser cold marking leaves a smooth mark on surfaces. When marking plastics, start by deciding what kind of marking is required. The use of ultraviolet and green lasers to photochemically change the material is one method, as is surface melting or foaming.
UDI marks on medical-grade plastics must be touchably smooth to prevent bacterial growth in certain locations. This is when using UV wavelengths for “cold marking” is useful.
For applications sensitive to heat degradation, cold laser marking with UV lasers modifies the material’s molecular structure, which is desirable. The heat affected zone is the term used to describe this thermal damage outside the marking area (HAZ).
TiO2, one of the additives included in white plastics, strongly absorbs UV radiation and causes a chemical reaction that darkens the plastic.
Instead of just leaving a mark on the surface of the plastic, this procedure leaves a mark that is smooth and quite legible. As UV-A radiation in these long waves poses no risk to the human body, it is frequently employed in cosmetic procedures.
However, the UV-B and UV-C radiations must be employed with the appropriate safety precautions when working with various materials and in various procedures since they might be harmful.
Because it destroys the bonds between atoms and molecules on the product, UV lasers are also known as “Cold lasers,” which keeps the product from overheating and resulting in exact and accurate outcomes on the substance as it evaporates, unlike other lasers,
The Global Cold laser marking machine market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Emtex has released the reasonably priced ELM5 (UV) laser marking machine made in India. Cold laser engraving is another term for the UV laser marking machine, which is also referred to as the blue laser beam.
This technology has the ability to engrave with a low rate of heat. One of the primary causes is the machine’s lightwave or UV light spectrum. Due to the fact that it doesn’t heat the material surface like CO2 and fibre do, this technique can engrave across a variety of materials.
It enables the UV laser to mark on all plastics and other materials that react negatively to heat in a clear and very precise manner. A 100% permanent design was produced using an advanced laser technology called a UV laser marking machine.
This machine uses a 355 nm light laser source that produces fine marking and a reduced focusing point diameter. Whereas a regular fibre laser cannot operate, their special wavelength enables product labelling.
The ultra-fine laser beam quality used in ultraviolet laser marking machines produces smooth, clear, and exact markings on a variety of goods, including rubber, nylon, glass, plastic, and other metals.
