In any type of highly precise and fine line indication at longer work distance than formal hand reaching, comparing with formal line drawing or printing work with manual line aligning tool, it would be a much better solution to apply a shorter wavelength made device of 405nm violet laser line generator. It gets much shorter wavelength of 405nm than other visible optical spectrum, which can be focused into a thin beam, enabling micron-level positioning accuracy, meeting the precise positioning requirements of packaging machinery. When violet laser module makes proper installation or integration with various packaging machine or device, not relying on any manual labor force input, it always assures quite easy reaching, high precision and high fineness violet line indication for various packaging machinery works conveniently.

The usual design of 405nm violet laser line generator is equipped with automatic power control and automatic current control circuit boards, thus violet laser beam maintains stable brightness and straightness over extended periods of operation, ensuring consistency during the packaging process. Being made with an import 405nm violet laser diode within 50mW to 100mW and high power up to 150mW to 500mW and metal heat sink cooling system inside a durable anodized aluminum alloy housing tube, 405nm violet laser module achieves superior nice heat dissipation, ultra stable and reliable violet reference line projection within constant work time of 10 hours per day.

The violet laser light provides strong contrast on the surfaces of most packaging materials, making the violet laser beam clearly visible even in complex lighting conditions, making 405nm violet laser line generator easy for operators to observe and for equipment to identify. Cooperated with adjustable focus optic lens, after freely adjusted laser line fineness, the projected violet laser line width is generally adjustable from 0.2mm to several centimeters, allowing for tailored adjustments based on the specific operating requirements of packaging machinery and adapting to various packaging scenarios. Being made with ultra compact size tube design of 16mm, 18.9mm or 26mm diameter, this violet line laser module can be installed in the confined spaces of packaging machinery, minimizing space and simplifying integration into various packaging equipment.

Applications in packaging machinery:

Material positioning: During the material conveying process, a projected straight violet line laser module serves as a positioning reference, helping the material to be accurately positioned. This ensures that subsequent packaging processes (such as filling and sealing) are carried out in the correct position, improving packaging accuracy and product consistency.

Cutting marking: For equipment that needs to cut packaging materials (such as cartons and films), 405nm violet laser modules provide clear cutting lines to guide the cutting tool for precise cutting, reducing material waste and improving cutting quality.

Labeling assistance: In labeling machines, violet alignment laser lines can be used to mark labeling positions, ensuring labels are accurately applied to the designated area of the packaging container, ensuring accurate and aesthetically pleasing labeling.

Folding guidance: In processes such as carton folding, violet line laser modules provide reference lines for the folding mechanism, ensuring the accurate fold angles and positions of each side of the carton, helping to improve packaging regularity and efficiency.
