Technology

Ink manufacturing uses advanced techniques to ensure consistency, durability, and high performance. Two essential methods are injection molding and extrusion, used to produce ink containers and cartridges.
  • Injection Molding – Creates reservoirs, caps, and casings by injecting molten material into molds for precise shape and texture.
  • Extrusion – Forms cartridges or tubes by pushing heated material through a die, then cutting to the required size.
These methods enable efficient large-scale production, ensuring each product meets high-quality standards for smooth and long-lasting performance.

Assembly

Assembly is a vital stage in ink manufacturing, where components are combined to ensure high quality, consistency, and smooth functionality.

Ink is filled into containers, cartridges, or marker reservoirs, then sealed to prevent leaks, labeled for traceability, and inspected for defects to ensure only the best-quality products reach the market.

A streamlined assembly process boosts efficiency, reduces waste, and maintains reliability, ensuring every ink product delivers optimal performance for writing, marking, and stamping.
