Toothbrush manufacturing process production process

   process flow

  1. Handle injection molding

   Place the granular or powdered plastic in the barrel of the injection machine and heat it to soften it and use a push rod or rotating screw to continuously extrude it from the die (the shape of the die is the desired The cross-sectional shape and length of the product depends on the demand), and the product is required after cooling.

  2. Value hair

  The brush head is implanted into the toothbrush handle by the hair value machine, and the hair is cut into various required shapes after the hair value.

  3. Polishing

   After cutting, if the bristles are not smoothly treated, they are simply damaged by being too sharp. Rounding the tips of the bristles can prevent this kind of damage.

  4. Tensile stress detection

  Because the toothbrush is used very frequently, the strength and elasticity of the toothbrush itself are very high.

  5. Packaging and delivery

   generally use ultrasonic welding machine or heat sealing machine to seal the plastic packaging of the toothbrush to prevent the invasion of bacteria.

  Material selection

  Toothbrush handle: PP, PS, PMMA, ABS.

  PP:

  Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0.90--'0.91g/cm3, which is now One of the lightest varieties of all plastics.

  PS:

   Polystyrene is colorless and transparent, can be colored freely, and its relative density is second only to PP and PE. It has excellent electrical properties, especially good high-frequency properties .

  PMMA:

  , commonly known as plexiglass, is a non-toxic and environmentally friendly material that can be used to produce tableware, sanitary ware, etc. It has outstanding chemical stability and weather resistance.

  ABS:

  ABS resin is one of the five major synthetic resins. Its impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties are excellent, and it also has easy Processing, product size stability, good appearance gloss, etc., simple painting and coloring, and it can also carry out secondary processing such as surface metal spraying, electroplating, welding, hot pressing and bonding. It is widely used in machinery, cars, and electronics. Electrical appliances, instrumentation, textiles and construction are a kind of thermoplastic engineering plastics with a wide range of uses.

  Toothbrush bristles: nylon, DuPont hair

   The bristles are mostly made of nylon, and the more advanced ones are made of American DuPont hair.
