Laser absorption characteristics

CO₂ Laser (10.6μm: The alumina absorption rate is over 80%, and the silicon nitride/silicon carbide can reach over 90% after surface treatment.

Polarized light control

The alumina absorption rate can be increased to 95%.

Wavelength selection

Ultraviolet laser (355 nm): Cold processing, with a precision of ≤ 5 μm, without thermal influence.

Infrared laser (1064 nm): Hot processing, prone to generating recast layers and rough surfaces.

Processing parameters

Excessive power→Melting / Evaporation

Too dense pulses→Hot crack

Optimization plan: Reduce the duty cycle and increase the pulse interval to avoid thermal damage.

Key to prevent cracking

① Select laser with matching wavelength;

② Progressive parameter adjustment (power + pulse optimization);

③ Enhance cooling and suppress thermal stress.

The majority of plasma spraying processes utilize the high-temperature plasma generated by a direct current arc as the heat source. The working gas is mainly argon, and hydrogen, helium, or nitrogen may be added to increase the arc voltage of the plasma.

When plasma spraying powder materials, gas is usually used as the carrier to transport the powder, which is then sent into the high-temperature plasma jet for heating and acceleration. 

The powder particles are heated to a molten or semi-molten state, and then fly at high speed and impact the surface of the workpiece, quickly spreading and deforming, and it quickly solidified, forming a layer upon layer of accumulated structural coatings.

The advantage of plasma spraying lies in the high temperature of the jet. Due to its flexibility, practicality, and high cost-effectiveness, it has been widely applied. 

Packaging: Used in holographic cards/films/boxes/bags, vibrant patterns on milk tea cups, moisture-proof coatings on potato chip bags, and anti-counterfeiting prints on cigarettes, alcohol, cosmetics, and banknotes, achieving a precision of 0.01 mm.

Home & Lifestyle: Affects the texture of wallpapers and flooring, the smooth or matte finish of magazines, patterns and labels on clothing, non-woven fabric surface modification, coatings on hygiene products, and the soft touch of leather—all relying on precise coating control.

Technology: Applied in lithium battery separators, silver paste circuits for solar panels, privacy screen protectors, and liquid crystal displays, enabled by nanometer-level coating techniques.

Customization requirements: From the 30LPI coarse mesh holes of corrugated cardboard to the 1500LPI honeycomb mesh of electronic printing, everything can be "tailored to the roll";

Composition and Characteristics

Offset printing ink is mainly composed of pigments, resins, solvents, etc. It has the characteristics of good fluidity and fast drying, and is suitable for multi-color printing and high-speed production. Its viscosity is moderate, which can meet the requirements of the printing machine for ink fluidity and adhesion.

Main Applications

‌Packaging Printing‌: Suitable for packaging printing on substrates such as plastic films and paper, such as food soft packaging, pharmaceutical packaging, etc. ‌

‌Publishing Printing‌: Used for color printing of books and magazines, as well as efficient production of labels. ‌

‌Commercial Printing‌: Includes areas such as business printing and label printing.

High adhesion

By adding nano-resin, the adhesion on PE/PP films reaches 5B (according to ASTM test).

Widescreen color gamut

Utilizes high-purity pigments, with the color gamut covering over 90% of Pantone.

Heat transfer ink is a technology that transfers patterns from transfer paper to the surface of the substrate by heating. It is mainly used for pattern printing on materials such as textiles, plastics, ceramics, and metals.

By heating, the ink vaporizes and penetrates into the material's interior, creating permanent coloring. For example, when the pattern on sportswear is transferred to the fabric through heat sublimation, the ink combines with the fibers, achieving a non-removable effect.
