Abstract:
A method of forming an oral care implement, a method of forming a head plate for an oral care implement, and an oral care implement or head plate formed therefrom. The head plate may have micro-sized or fine features. The method may include providing an amount of a first solid material upstream of a first mold cavity; prior to the first solid material entering the first mold cavity, applying ultrasonic energy to the first solid material to melt the first solid material into a first molten material; flowing the first molten material into the first mold cavity; allowing the first molten material to harden within the first mold cavity to form a head plate comprising micro-sized features; forming a body from a second material, the body including a handle portion and a head portion; and coupling the head plate to the head portion of the body.
