CLOSED LOOP FEEDBACK PRESS

The pressing of an article is achieved with a closed-loop feedback press. The closed-loop feedback press is effective to measure an amount of pressure applied and adjust the pressure to achieve a prescribed amount of compression on the article. Further, the press may leverage a closed-loop feedback system to maintain a consistent temperature of one or more platens. The press is able to adjust a pressure applied one or more times during a pressing operation to accelerate a temperature change in the pressed article while reducing the pressure applied as the temperature approaches a target temperature to limit unintentional deformation and bleeding of the pressed material of the article.

Bonding objects together

A method of bonding a connector to a first object includes providing the connector, the connector being separate from the first object and including a thermoplastic material; arranging the first object and the connector relative to one another so that the connector reaches from a proximal side of the object through a first opening in the object; generating and applying vibrations and mechanical pressure to the connector until a flow portion of the thermoplastic material is liquefied and caused to flow sideways radially into an open space; and removing the source of the vibrations and causing the liquefied thermoplastic material to re-solidify, resulting in the connector with a foot portion, a head portion, and a shaft portion between the foot portion and the head portion. The shaft portion extends along an axis through the first opening, and secures the connector to the first object.
