A first plastic part is fixtured in a first fixture, and a second plastic part is fixtured in a second fixture for welding to each other. The first plastic part can be independently moved relative to the second plastic part in each of three directions: 1) linearly in a direction parallel with a z-axis, 2) linearly in a direction parallel with an x-axis, and 3) circularly in a circular arc about an axis parallel with a y-axis.

Machine and method for welding plastic parts together

A method of evaluating flatness of a two-dimensional area of a surface of an unfinished workpiece prior to performance of a process step in which a prescribed operation is performed on the surface by a tool. A flatness value for the surface is calculated and used either to allow or to disallow the prescribed operation to proceed, and when allowed, uses the flatness value for parameter adjustment.

A plastic welding machine for welding plastic parts together is capable of controlling the weld force vector in both magnitude and direction.

In a process for welding plastic parts together, an IR shield redirects IR radiation emitted from a heater of a heating tool so that IR radiation which would otherwise be directly incident on certain portions of a plastic part and/or on other parts of the heating tool is avoided.

Limiting dispersion of IR radiation from a heater element during plastic welding

A machine which repetitively performs an operation, or operations, on mass-produced parts which are subject to part-to-part variations compensates for such variations by self-adjustment of its operation, or operations, at a location, or locations, where an operation, or operations, is, or are, performed.
