Fdrill vs the traditional craft

fdrill热熔钻与传统工艺对比


fdrill热熔钻头加工过程
Fdrill is a thermal drilling process that produces a bushing formed from the parent material by plasticising it. This is an alternative to traditional fastening methods as Fdrill uses the material itself to form a stronger connection.
