  • Method and device for manufacturing pellets of hot-melt ink
    Patent number: 7252280
    Abstract: A method for manufacturing pellets of hot-melt ink which includes the steps of filling molten ink into a mold cavity defined by a first die and a second die of a mold, allowing the ink to cool down and solidify in the mold cavity, and heating at least one of the first and second dies for re-melting the surface of the ink pellet to facilitate its removal from the mold cavity.
    Type: Grant
    Filed: August 20, 2003

  • Method for manufacturing pellets of hot-melt ink
    Patent number: 6692668
    Abstract: A method for manufacturing pellets of hot-melt ink which solidifies with a cooling rate-dependent shrinkage, comprising the steps of filling molten ink into a mold formed by two mold dies, allowing the ink to cool down and to solidify in the mold, and opening the mold and removing the ink pellet therefrom, wherein in the cooling step, the ink is shock-cooled with a cooling rate that results in a shrinkage sufficient to cause the solidifying ink to separate from at least one of the mold dies.
