Among them, UV laser marking machine has been favored by more and more companies due to its unique laser wavelength and marking method, outstanding performance in identification clarity, durability and environmental protection.

UV laser marking machine is not only suitable for the identification of metal materials, but also can achieve high-quality marking effects on a variety of non-metallic and plastic materials. This equipment is widely used in industries such as electronic products, medical devices, cosmetics, food packaging and luxury goods, helping companies to effectively enhance their brand image and product traceability.

However, with the diversification of market demand, companies pay special attention to the adaptability of different materials when choosing marking equipment. Therefore, this article will explore whether UV laser marking machine is suitable for marking different types of materials, including plastics, metals and non-metallic materials, and analyze its performance on various materials to provide reference for related industries.

1. Basic principle of laser marking machine

UV laser is a laser with a wavelength range of 190-410 nanometers. Its basic principle is to emit a high-energy ultraviolet beam through a laser source to locally heat and evaporate the target material. During the marking process, UV laser can accurately control the size and energy of the spot to achieve a subtle marking effect. The process involves the absorption, conversion and removal of light to produce the required text, image or other pattern.

2. Technical features

● High resolution: UV laser marking machine can achieve extremely high marking accuracy, and its beam diameter can reach micron level, which is suitable for complex and small marking tasks.

● Low thermal impact: Compared with other types of lasers, UV laser produces a very small heat-affected zone during marking, which can effectively avoid deformation, burning or thermal damage of the material, and ensure that the surrounding materials are not damaged during marking.

● Wide applicability: UV laser marking machine is suitable for a variety of materials, including plastics, glass, ceramics, coated metals, etc., which can meet the needs of different customers.

● Environmental protection: The UV laser marking process does not produce harmful gases or waste, meets the requirements of modern environmental protection, and is suitable for use in various production environments.

3. Comparison with other laser marking machine

● Comparison with CO₂ laser marking machines

Different wavelengths: The wavelength of CO₂ lasers is usually 10.6 microns, which is mainly suitable for non-metallic materials such as wood, paper and certain plastics, while UV lasers are more suitable for application scenarios requiring high precision and detailed marking.

Thermal impact: CO₂ lasers generate high heat during marking, which may cause deformation or burning of materials, while UV lasers can better protect the surface of materials due to their low thermal impact characteristics.

Scope of application: CO₂ laser marking machines are mainly used for large-scale production of wood and paper products, while UV lasers are more widely used in high-end products in the electronics, medical, cosmetics and other industries.

● Comparison with fiber laser marking machines

Wavelength and absorption characteristics: The wavelength of fiber lasers is 1064 nanometers, which is usually suitable for metals and certain specific plastics, while UV lasers are suitable for processing low-light-absorbing materials, such as transparent or light-colored plastics.

Marking effect: UV laser can achieve more detailed marking effect, especially suitable for applications that require fine patterns and logos, such as coding of electronic components, while fiber laser performs better in fast marking and deep marking.

Equipment maintenance: Fiber laser marking machines generally require less maintenance, while UV laser marking machines may require more professional maintenance due to their more complex technology.

UV laser marking machines play an important role in modern industrial marking with their high precision, low heat impact characteristics and wide material applicability. Their performance and application scenarios make them indispensable equipment in many industries. Click here for more information

1. Plastic materials

● Commonly used plastics

PET (polyethylene terephthalate): widely used in bottles and containers, UV laser marking can form clear marks on its surface, suitable for the food and beverage industry.

PP (polypropylene): commonly used in electronic products and packaging materials, UV laser marking can form high-contrast marks on the PP surface, and it is not easy to wear.

PVC (polyvinyl chloride): commonly used for pipe and cable protection, UV laser marking has good adhesion and durability on PVC, suitable for various outdoor applications.

● Effect of UV laser marking on plastic surface

Marking effect: UV laser can make white, dark or transparent marks on the plastic surface, with clear marks and high contrast. The low heat impact during the marking process reduces the risk of material damage and maintains the integrity of the material.

Durability: UV marking has good chemical resistance and wear resistance, especially suitable for various plastic products used in daily life, such as cosmetic packaging and medical containers.

2. Metal materials

● UV laser marking effect on coated metals

Aluminum and stainless steel surface coatings: UV lasers can accurately remove the coating on the metal surface, exposing the metal substrate underneath, thereby achieving high visual contrast marking. Especially on aluminum, the marking effect is remarkable, providing clear and durable marking.

Diversified marking: For different coated materials, UV laser marking can produce different effects, including black and white contrast, color changes, etc., and has strong adaptability.

● Impact and control on metal substrates during marking

Due to its highly concentrated beam energy and low thermal impact, UV laser marking can effectively control the impact on metal substrates. Compared with traditional lasers, UV lasers greatly reduce the penetration of heat into metals, avoiding the problem of thermal deformation or burning of substrates.

By adjusting laser parameters (such as power, frequency and marking speed), the marking effect of metal substrates can be further finely controlled to ensure the beauty and durability of the mark.

3. Non-metallic materials

● Applicable non-metallic materials

Glass: UV lasers can accurately mark without damaging the glass surface, suitable for wine bottles, cosmetic bottles, etc., to ensure clear and visible markings.

Wood: Clear patterns and text can be produced on the surface of wood. The environmental protection characteristics of UV laser marking make it an important application in custom furniture and crafts.

Ceramics: Ceramic surfaces usually require high temperature and hardness. UV laser marking can solidify a lasting pattern on its surface, which is suitable for bathroom and home appliances.

● Advantages and performance of UV laser marking on these materials

High precision and fineness: UV laser marking can achieve high-resolution and fine marking on the surface of non-metallic materials, which is suitable for works of art and brand promotion materials.

Durability: Excellent marking of non-metallic materials, because UV laser marking usually does not cause structural damage to the material, and the marked surface has good wear resistance and corrosion resistance.

Environmental protection: The UV laser marking process does not volatilize chemicals, meets environmental protection standards, and is particularly suitable for products such as food and cosmetics that require strict compliance with hygiene regulations.

The wide applicability and excellent performance of UV laser marking machines in various materials (plastics, metals, non-metals) make it an important technology in modern industrial identification and brand promotion. Its high precision and low thermal impact characteristics further broaden the application scope of laser marking and meet the needs of different industries. Click here for more information
