Before that, we have introduced two ways to choose laser marking machines for materials of different materials. So today, let's continue to see what other materials will be used in other different marking machine types!
Because of their lightweight, durable and easy-to-process characteristics, plastic and acrylic sheets have been widely used in advertising display, building decoration, electronic equipment housings and high-end consumer goods industries. The high light transmittance and hardness of these materials require that the marking scheme must be clear and long-lasting, and surface damage must be avoided.However, in the face of a variety of marking equipment on the market, choosing the right model often becomes a difficult problem for enterprises-the differences in physical properties of different plastic types (such as ABS, PVC or PMMA), the accuracy requirements of logo content (such as LOGO, barcode or text), and production efficiency requirements all require systematic evaluation. Today, based on industry practice, let us analyze how to clearly choose marking machines for plastics and acrylic.
Before choosing a marking machine, the company must first confirm the type and nature of the marking material. For example, the transparency of acrylic sheet (PMMA) requires the marking process to avoid thermal damage, while the hardness of ABS plastic requires the marking depth to be considered. At the same time, we must also clarify the marking requirements. For setting the size and clarity standards of the identification content (such as micron-level resolution), and conducting sample tests to verify the effect. In terms of production efficiency, we need to calculate the average marking time (such as time-consuming per unit product) so that it can match the production rhythm and avoid our diode laser marking machine being idle or bottleneck.
For plastics and acrylic, mainstream options generally include diode laser marking machine and ultraviolet laser marking machine. Diode laser marking machine uses gas laser technology in the infrared band (wavelength of about 1064µm), which has a high absorption rate of non-metallic materials such as plastics and acrylic, and can achieve clear and long-lasting marking. The advantage of diode laser marking machine is that it is suitable for fine and large-area marking, such as the long-term marking needs of billboards or display stands. It has high output power and high energy conversion efficiency (up to 30%-40%), and supports software editing of graphic text and flexible changes. Diode laser marking machine adopts radio frequency laser and high-speed galvanometer, which has fast marking speed and high yield, and is suitable for mass production (flight marking function can be installed and assembly line integration). Diode laser marking machine has low maintenance costs (no consumables, the laser is maintenance-free for 30,000 hours), energy saving and energy saving, but it needs to be carefully evaluated for deep carving or ultra-wide-range applications.
Another option is an ULTRAVIOLET laser marking machine, which is suitable for plastic and acrylic scenes that require color or ultra-fine marking.Its thermal effect is small, it can avoid surface damage to the material, and it is suitable for the detailed treatment of electronic housings or decorative plates. However, compared with diode laser marking machine, UV models are more expensive and may be slightly less efficient in large-scale production.
In terms of print quality, select the appropriate resolution (such as adjusting according to the transparency of the material), and verify the clarity through sample testing. The printing speed needs to match the production requirements, ensure stability and consistency (such as processing capacity per hour), and avoid speed fluctuations affecting the marking effect. Diode laser marking machine performs better at this point, and its high-speed galvanometer technology can achieve high-precision continuous operation.
Through the above steps, enterprises can efficiently choose marking schemes suitable for plastic and acrylic.
