Abstract:
Apparatus and methods for injection molding, in which at least one portion of at least one cavity surface that defines a mold cavity, includes a thermally controllable array.
Abstract:
Microneedle arrays made by an injection molding process that uses ultrasonic energy to assist flow of polymer melt into a mold cavity, said microneedles having a high proportion (at least 60%) of fill, i.e., completely formed microneedles across the array. Microneedle array can be on a base or land no more than 250 μm thick.
