How to ensure the best effect of laser cutting acrylic

Acrylic, also known as plexiglass, is a polymer material with good transparency, chemical stability, and plasticity, it has a very wide range of applications in many fields and is currently one of the most common non-metallic materials.

Acrylic processing performance is excellent, both using thermal processing molding and with mechanical processing of cutting plasticity, our daily life common acrylic products include acrylic light boxes, acrylic signage, acrylic doors and windows, acrylic lampshades, acrylic furniture, etc., a wide variety of acrylic products, covering almost all areas from home to industry.

 

Laser is one of the main ways to cut acrylic processing, laser cutting acrylic has many unique advantages, such as high processing accuracy, processing speed, non-contact processing without mechanical stress, automation, and so on. However, laser cutting acrylic is not simply pressing the button and waiting for processing on the line, want to cut the best results, the following aspects must be noted:

 

1. Material pretreatment: acrylic surface dust and dirt will affect the effect of laser processing, before processing should pay attention to keeping the surface of the material clean, part of the surface of the acrylic will have a layer of protective film, pay attention to the use of laser equipment with film cutting function, if not recommended to remove the protective film and then cut.

 

2. Laser parameter settings: laser parameters, power, speed, and focus are the main parameters of cutting, in general, cutting thicker acrylic requires higher power, but too high a power may lead to the edge of melting, the power is too low may not be able to cut completely. Before we start processing we need to repeat the control test and use the most appropriate laser parameters.

 

3. Processing mode: the processing process on the final results also has a great impact, such as cutting a thicker acrylic plate, if the laser power is not enough, a single cut using a slow high power to carry out, is very likely that the edge of the burnt and so on, at this time you can increase the speed of power reduction, and then repeated processing, which can reduce the heat accumulation of the cut to avoid the edge of the over-burning.

 

4. Equipment maintenance: well-run equipment is the basis for smooth processing, so we have to do a good job of regular maintenance of equipment and Pojet, especially the optical path and mechanical axis part. For example, the focusing mirror long-term exposure to soot, is easy to contaminate, if not cleaned up promptly, it will lead to a light path skewed, affecting the processing effect.

 

Laser-cutting acrylic wants to ensure the best results and should be well-prepared in all aspects, not only when processing to adjust the parameters, but before and after processing should also pay attention to a variety of details. Of course, laser cutting is not so easy to make mistakes, as long as there are no major problems, the basic cutting effect can still be guaranteed.

History of Lasers

Image
  Lasers have been hailed as one of the great inventions of the twentieth century, following nuclear power, computers, and semiconductors, and have brought about a great technological breakthrough for mankind. The laser radiation produced by lasers is famous for being the "fastest blade", the "most accurate ruler" and the "brightest light". Nowadays, laser technology plays an important role in many fields such as medicine, the military industry, communications, and so on.   The birth of the laser is the result of the tireless efforts and arduous exploration of many scientists.   In 1917, Albert Einstein proposed the concept of "stimulated radiation", which laid the cornerstone for the theoretical foundation of lasers.   Although the theory of lasers had already been proposed at that time, the actual preparation of lasers was quite challenging. By the 1950s, with the progress of photon and microwave technology, the manufacture of an oscillator cap...

Automated laser welding improves MDM yields

Image
Hiring and training skilled personnel is not only costly, but in today's labor market, it is becoming increasingly difficult for companies to find and retain this talent. Automated laser welding systems dramatically reduce the need for skilled personnel. For example, once an engineer or technician has specified and stored all aspects of a welding application using the machine software, the operator can safely initiate the welding process with limited access to functions through the GUI.   Avoiding subjective judgment on the operator's part, combined with the use of in-situ vision, process monitoring, laser monitoring, and post-process validation features, provides consistent production, increased yields, and reduced scrap. Whenever there is any deviation from the specified limits in the process, the machine makes the necessary adjustments or stops the process and alerts the operator. This is clearly a benefit for any application. It would be especially beneficial when welding p...
