High-Precision Industrial Tampo Pad Printing
At ADIRAJ COATING PVT. LTD., we deliver industrial pad printing (tampography) that sets the benchmark for visual acuity, sharp micro-definition, and durable adhesion on challenging geometry. Operating out of our specialized Chakan facility, we cater directly to automotive Tier-1 cockpit component makers, electrical switchgear manufacturers, and consumer electronics brands.
Pad printing solves a vital manufacturing challenge: applying intricate 2D images, warning labels, ISO symbols, and multi-color branding onto 3D shapes that cannot be printed by conventional flat-bed methods—such as spherical knobs, concave pushbuttons, cylindrical levers, and textured injection-molded housings. By utilizing deformable elastic silicone transfer pads and hardened steel photopolymer cliché plates, our process picks up a microscopic ink film from the etched engraving and transfers it seamlessly without optical distortion.
Core Technical Strengths
Micro-Registration (±0.05mm)
Precision CNC fixtures and micrometer adjustment tables guarantee tight multi-color alignment without ghosting.
Automotive 2K Hardened Inks
Solvent and UV-curable inks with specialized cross-linkers withstand hand perspiration, cleansers, and harsh road oils.
Complex 3D Geometry
Custom-molded silicone pads conform flawlessly to compound curves, steep angles, textured surfaces, and recessed cavities.
Cleanroom Application
Controlled air-filtered printing environment prevents dust particle entrapment for zero visual defect rejection.

Standard Operating Procedure
Artwork & Cliché Etching
Vector graphics are converted to micro-etched steel plates with depth calibrated to exact micron ink release.
Surface Ionization & Cleaning
Components are pre-cleaned and de-ionized with anti-static air guns to eliminate surface dust and static charges.
Pad Ink Transfer
Elastic silicone pad depresses into ink cup, lifts the tackified image film, and transfers it onto the part with pinpoint alignment.
Thermal Cure & Audit
Parts are cured in temperature-regulated drying tunnels, followed by rub resistance and tape adhesion verification.
