Today, plastics are utilized in areas where metals were the preferred choice just a few years ago. With plastics, it is possible to integrate various processes and functions into a single component and manufacture that component in a single production step.
However, with plastic constructions, you arrive at the point when the manufactured component needs to be connected. Our answer to the necessity for a well-priced and reliable connection is self-tapping direct screw fastenings under the ARNOLD REMFORM® brand. Our thread-rolling screw with its asymmetric thread profile is screwed into a pre-formed boss, resulting in an economical, recycling-friendly assembly, and which can be removed and reinstalled.
Benefits
The choice of thread geometry can have a considerable influence on the quality of the joint. Here, the thread performs two tasks: First, the thread serves as the forming tool when tapping. Second, there is a form-fit connection which the screw cannot loosen by itself.
Characteristics
Improved plastics flow reduces loads on the boss material and ensures a fastener which is suitable for plastics. The high thread engagement with ARNOLD REMFORM® ensures that the cutting surface is substantial. This increases the fastening's over-torque, and the lower load on the boss material allows higher pre-load forces. This creates a durable connection at the maximum residual pre-load force.
Advantages
Compared with insert solutions, REMFORM® saves time and money:
- No additional joining elements needed
- No additional insertion process needed
- No risk to mold tooling, eliminates tilting when closing die
- Significantly reduced cycle time
- Asymmetric thread
- Optimized material flow
- Minimum tube load
- Optimum planning security
- Simple boss design
- High level of process reliability
