The b&m-REPTO® B is a threaded bolt for embedding in thermoplastics and duroplastics. The external thread of the bolt, which can be designed both as metric and as customer-specific, can be used for joining and assembling further components. It ensures a process-reliable and highly repeatable connection.
The b&m-REPTO® B can be embedded in the plastic by various embedding processes such as heat embedding, ultrasonic embedding and overmolding. Thereby, the knurl geometry has to be designed for the respective embedding process. An ideal knurl selection is essential for a later load case. Depending on the selection of geometry and material, the b&m-REPTO® B can be manufactured by machining or completely by cold forming. In the innovative production process using cold forming, the applied material can be used more efficiently and the thread strength can be further increased.
