ONE SHOT self-punching fastening system BÖLLHOFF
An ever increasing diversity of models and variants, new designs and materials as well as decreasing development times and product cycles lead to new and manifold tasks when connecting the most different materials.
To meet these high requirements to the fastening technology, fasteners and processing systems must be perfectly designed and harmonised. Böllhoff, as a specialist for fastening and assembly technology, and FRIMO, as a specialist for tooling and machinery, have jointly developed an integrated process.
The benefit for the customer: bundled fastening and processing know-how for faster and economical processes.
State-of-the-art: ”Two-shot process”. The state-of-the-art technology for producing hole reinforcements and inserting threaded inserts or similar
fastening elements is called "two-shot process". This process consists of two steps: punching including waste removal as a first step and inserting and beading over the fastening element as a second step. The problem is, that the exact position of the punched-out hole must be located again. Thus, the overall process
is prolonged and complicated.
Böllhoff and FRIMO have considerably improved this punching and joining process! The result is called ONE SHOT process, 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
