Abstract: Systems and processes that limit distortion of inserts (e.g., previously formed parts) in insert molding and overmolding processes. Initially, a mold may be closed (e.g., clamped) about an insert with the mold at a first temperature. After closing the mold about the insert, the mold is heated up to a second temperature (e.g., a temperature suitable for injection of the molding material) and filled with the molding material to contact (e.g., encapsulate) the insert. After the mold has been cooled, the mold may be opened and the finished part (including the insert and the solidified molding material) removed (e.g., ejected). The process may be repeated for additional finished parts. Closing the mold about the insert before heating the mold to the injection temperature advantageously limits distortion of the insert that would otherwise occur by placing the insert into the mold with the mold already at the injection temperature.

The die plate, cutting chamber and rotary cutter can have the same structure as an underwater pelletizer, but operating without water or liquid as a dry face pelletizer. The thus formed wax pellets drop out of the cutting chamber by gravity through an opening in the bottom thereof.

Abstract: Mineral samples for use in analytical instruments are created by a system that greatly reduces the sample preparation time and facilitates automation. For example, in some implementations, rather than grinding to expose the interior of mineral particles in sample plug containing mineral particles in an epoxy compound, the sample plug is sliced with a saw, which more rapidly provides in many applications a sufficiently smooth surface on the exposed particle surfaces for observation. Rather than slowly mixing a slow curing epoxy to avoid introducing bubbles into the sample plug, some implementations use a fast settle fixative and a mechanical mixture that avoid bubbles.
