Non-contact marking of plastic materials with 355nm UV laser

 

New Era Securities analysis pointed out that the current national helmet penetration rate is extremely low. It is conservatively estimated that the production and sales of helmets will not exceed 50 million yuan per year. The demand for new helmets may exceed 300 million. If the average price is 100 yuan per piece, it corresponds to 30 billion yuan. Market demand.

 

Laser marking helps helmet production

As an important product that protects the personal safety of consumers like masks, the quality of helmets is also an important element that businesses should consider. How can we make our own helmets more popular with consumers, eliminate copycats from other friends, and improve efficiency? Laser marking technology will help businesses.

 

The use of laser marking as a processing method has the advantages of no processing force between the workpiece, no contact, no cutting force, and low thermal influence, ensuring the original accuracy of the workpiece. At the same time, the marking is fine, and the lines can reach the order of millimeters to micrometers. It is very difficult to imitate and change the marks made by laser marking technology, which is extremely important for product anti-counterfeiting.

 

Merchants can choose ultraviolet lasers to mark important information such as helmet material, production information, use precautions, and anti-counterfeiting labels on the helmet. It is not only beautiful to show the product personality, but also anti-counterfeiting treatment to eliminate the copycats of friends and merchants.

 

How to choose the right laser?

 

It is particularly important to choose high-quality UV solid-state lasers in industrial applications. A good UV solid-state laser should have the following advantages:

 

One, high precision. Ultraviolet lasers are often used for micromachining, and higher precision can ensure the accuracy and integrity of marking.

 

Second, it is easy to install and maintain. Many lasers are relatively cumbersome to install, and corporate purchases often take a lot of time to debug and install, which greatly occupies the development and maintenance costs of the enterprise. The excellent laser circuit design is simple, easy to install, and uses CNC control, which makes it easy to get started.

 

Third, the stability is high. A good UV laser usually has a wavelength below 0.4μm, a stable beam, and a balanced energy control. It can effectively micro-process the polymer material without showing signs of burn damage to the material.

 

Combining the above characteristics, RFH UV laser is an ideal choice.

RFH Expert Ⅱ 355nm ultraviolet laser has a laser wavelength of 354.7nm and a wide range of repetition frequency (single pulse to 200kHz), which can be better absorbed by the material and is less destructive to the material. At the same time, it has superior beam quality (M2<1.2), which is strictly guaranteed in all frequency ranges; pulse width <20ns@30k, the heat-affected area during processing is small, and it supports digital intelligent power control, simple operation, low hands-on cost, Suitable for various laser application control needs.

 

Relevant experts believe that: in the final analysis, helmets are not used for speculation, it is just a tool to protect personal safety. Buying a helmet is just the beginning. Wearing a helmet in accordance with regulations can effectively avoid or reduce injuries. It is the proper meaning of a civilized society to return public opinion to the theme of "security guarding".

 

As a supplier of industrial-grade high-end solid-state lasers for 13 years of Seiko, RFH Laser hopes to use laser technology to help the helmet industry develop efficiently and healthily.
