Toothbrush is a dental instrument that is used to clean the teeth, along with toothpaste or mouthwash. It comprises the handle that is made from plastic and small nylon bristles fixated into the brush’s head. The modern designs of toothbrush offer wide range of styles and shapes in the market and they are mechanically produced.
Generally, toothbrushes are made up of natural boar or nylon bristles and plastic handles. How is toothbrush made?
- The first step involved is molding the handles. First, the plastic is shaped into pellets and these will be placed in an injection molding medicine that heats the plastic until melted. The rotating screw of the plunger forces the liquid into the handle molds that will form the entire handle which includes the small hole or cores where the bristles are inserted. The molds are clamped securely with pressure employed into the molds, while the plastic is cooling. If the molds have sufficiently cooled, the clamps should be removed with the small pins pushing the handles out of the molds.
- Then the bristles that are made from nylon are placed into the core or small holes of the handle automatically. The bristles are stapled into the core using tiny metal staples.
- The next step is trimming the bristles. The toothbrush passes through the machine for trimming that slice the bristles into appropriate length and shape for specific design.
- The toothbrushes are packaged into plastic or cardboard containers. Labels are to be attached into the package to give information or details about the product including the hardness of the bristle and the usage recommendation.
- And finally, toothbrushes that are bundled are to be clustered into much larger shipping crates or boxes and they are delivered to distributors.
