Materials Selection:
Toothbrushes begin with carefully chosen materials. The handle is typically made of plastic, while the bristles can be nylon or natural boar hair.
Plastic pellets are mixed and shaped into handles, ready for the transformation.
Injection Molding:
The plastic pellets are placed in an injection molding machine. Heat melts the plastic, and molds shape it into the desired toothbrush handle design.
Handles take form, ready to embrace bristles.
Bristle Attachment:
Bristles, often made of polished nylon, are folded and automatically placed into position.
Tiny staples secure the bristles to the plastic body of the toothbrush.
Trimming and Quality Control:
The toothbrush body and bristles go through a machine that trims the bristles to uniform length.
Rigorous quality checks ensure each toothbrush meets standards before packaging.
