bercobrush® octopus anchor wire

The new anchor wire for plastic toothbrushes

Tuft retention continues to be a major priority in the manufacturing of plastic toothbrushes. However, current grooved anchor wire designs have maxed out their tuft retention capabilities.  Enter bercobrush octopus, a completely new and innovative approach from bedra, the leader in anchor wire technology.

Increased tuft retention up to 20%

bercobrush® octopus utilizes a new structure, modeled after the suckers on an octopus leg, to dramatically increase tuft retention.  This newly structured design is perfect for applications that require enhanced tuft retention or for situations that require equivalent tuft retention in a smaller footprint.  These designs also offer excellent economic advantages.  Compared to a double-sided triple grooved wire, bercobrush octopus utilizes 3% less materials per meter and up to 9% less compared to single-sided triple grooved wire. 

  • Increased tuft retention up to 20%
  • No deformation during punching
  • Equivalent tuft retention utilizing smaller wire dimensions
  • Reduced material usage up to 9%
  • Customized designs available upon request

Smaller wire, bigger effect: reducing wire sizes will save material and thus costs. The dimensions for bercobrush® octopus are 1.40 x 0.25 mm. The fact that here minimum format and maximum quality go together is a strong argument in favor of bedra. Closest tolerances, high tensile strength and reproducibility are certainly standard. On request we also develop wires to your specific requirements.
