ONE SHOT - A self-punching fastening system for structural components of fibre reinforced plastics
The ONE SHOT process
The ONE SHOT process is a self-punching fastening system based on an innovative tooling technology in which newly developed fastening elements are utilised. This procedure is suitable for thin-walled structural components of fibre reinforced plastics, such as GMT, CFRP, SMC, PP long fibre.
The ONE SHOT process advantages:
Simple and safe production process . only one step
Locating the hole afterwards is no longer necessary
Clearance-free fit between fastening element and component
High level of ejection and anti-rotation safety
Clean cutting of anisotropic fibre structures
Minimised excess length on the backside
Plastic component 2 - 4 mm strong (up to 8 mm for GMT)
Punching, waste removing, inserting and beading – all in one step
Variations of the ONE SHOT fastening element
Thread insert
Hole reinforcement (round, oval)
Customer specific requirements can also be realised, e.g. threaded bolts, ball bolts, etc.
Technical Data
ONE SHOT thread insert with knurl joined into a 7.5 GMT (30 % GF). At room temperature, the axial load bearing capacity contrary to the setting direction FA[N] and the torque ML[Nm] depending on a bead have been measured.
