Detailed Application Scenarios

Toy and Stationery Printing HY-902 heads print clear cartoon patterns and logos on toy cars, figures, blocks, pen barrels and erasers. Uniform ink pickup, many transfer times, long service life for large volume production. Non toxic and odorless, meeting toy safety standards.

Electronic Housing Printing HY-902 heads print clear logos and button marks on phone housings, chargers, remote controls, mice and keyboards. Sharp edges, uniform ink layer, strong adhesion. Good deformation recovery for accurate multi color registration.

Application and Operation Instructions Step 1: Prepare clean mold and tools, wear nitrile gloves. Step 2: Weigh A and B components at 100:2 to 100:3 ratio accurately. Step 3: Stir slowly in same direction for 2 to 3 minutes until uniform. Step 4: Vacuum defoam at negative 0.1 MPa for 3 to 5 minutes. Step 5: Pour slowly into mold from one side, avoid bubbles. Step 6: Cure 3 to 4 hours at room temperature, demold, rest 24 hours before use.
