In-line Laser Marking Equipment

Inline inkjet coder

Name: Inline inkjet coder
Brand: SINOMV
SKU: SK-350 / SK-450

Single-head, single-track, one-side coding. SK-350 is a small-character coder up to 350×350 mm; SK-450 is a micro-character coder up to 450×450 mm.

The inline inkjet coder prints one side of a board on the line. SK-350 uses a 65 μm nozzle at 1148 characters per second. SK-450 uses a 40 μm nozzle at 1514 characters per second. Print accuracy is ±0.02 mm and character height is 0.6–6 mm. Conveyor height is 900±20 mm, and the direction can be switched. Vision sets the print position, reads fiducials and compensates them, and the line can take MES work orders, block duplicate codes and handle X-out boards.

Questions

Which laser source should I pick?

Use fiber on many metals, UV when heat would mark a polymer or glass, and CO2 on wood, acrylic, paper and leather. S500-X, S450-X and S350-X can be configured with the source the material needs.

Do I need two heads for two sides?

No. S350-X, S450-X and S500-X can each be configured as single side, flip both sides, or dual-head both sides. Board ranges go to 350, 450 and 500 mm.
