The manufacturing of industrial electronics, such as relays and switches, requires the marking of intricate schematics and multiple certification symbols on small surface areas. These components often feature transparent or colored plastic housings that demand a high-contrast identification solution. OMA JET's PIJ (Piezoelectric Inkjet) technology has become the professional choice for this specialized application, providing the clarity and durability needed for technical compliance.
1. High-Contrast White Marking on Dark or Transparent Surfaces
Many electronic housings are made of amber, black, or transparent plastics where standard black ink is invisible. OMA JET's PIJ systems utilize specialized high-pigment white UV inks that provide exceptional opacity. This ensures that even the smallest font sizes and finest circuit lines are clearly visible against the housing. The resulting mark is crisp and professional, ensuring that critical safety information is easily readable by technicians and inspectors.
2. Micro-Precision for Complex Diagrams and Symbols
Electronic components like the one in the image require the marking of tiny certification logos (CE, UL, TUV) and complex wiring diagrams. The OMA PIJ technology utilizes industrial printheads that achieve resolutions of 600dpi or higher. This precision allows for the marking of variable technical data and intricate symbols on a fraction of a millimeter, ensuring that all regulatory information is perfectly presented without any blurring or loss of detail.
3. Permanent Adhesion Against Friction and Chemicals
Industrial components must survive years of service, often in environments where they are exposed to vibration, dust, and cleaning chemicals. Our integrated UV LED curing system solidifies the white ink instantly upon contact. This creates a permanent, scratch-resistant bond with the plastic surface. The mark remains intact throughout the product's lifecycle, resisting the physical rigors of installation and the chemical exposure common in industrial control cabinets.
4. Safe "Cold Marking" for Sensitive Internal Circuitry
Sensitive electronic components can be negatively affected by the heat generated by some laser marking processes. OMA PIJ is a purely mechanical "Cold Jetting" process that operates at ambient room conditions. Because there is no thermal stress involved, the delicate internal coils and contacts of the relay remain completely safe and protected. This ensures that the identification process never compromises the electrical performance or reliability of the device.
Conclusion: By providing the ultimate combination of high-contrast clarity and material safety, OMA JET's PIJ inkjet solutions are helping the electronics industry achieve superior identification quality. With a decade of expertise in industrial coding, OMA JET remains the trusted partner for delivering high-performance marking technology to the global electronics market.
