Apparatus and methods for jetting liquid material in desired patterns

摘要

An apparatus 10 for jetting liquid material in desired patterns includes a jetting module 18 that is couplable to a source of liquid material 12. A piston 46 is disposed for movement within an interior chamber 42 to rapidly develop high pressure within the module 18 so that liquid material 12 is jetted from through a pattern plate 70 in a desired pattern.
