EPPsys RSD

Specification

Overview
- Friction welding geometry specifically developed for EPP foams
- Ideally suited for tolerance-independent assembly because no pilot hole is necessary
- Easy assembly after the foaming process
- Special drive bits available for the different drive geometries
- Usage in foam densities from RG30 to RG250
- Weight savings and recyclability thanks to the use of polymer material
- Available in large (22mm) and small (12mm) diameters as an insert for use with EVO PT® screws Ø 5mm and 6mm

Friction welding insert for EPP foams

The EJOT^® EPPsys RSD („Reibschweißdom“ = friction welding boss) is an effective fastening element for EPP foams. The innovative friction welding process directly embeds the fastener in the EPP foam and securely connects it to the molten material. Then the EPPsys RSD enables easy and reliable direct fastening with the EJOT EVO PT^® screw.

EJOT Delta Tubus as an alternative to friction welding

EJOT® EPPsys RSD is a fastening element that enables greater use of foamed components in assemblies to achieve valuable weight and cost savings. The broad application-specific product range of EJOT® EPPsys gives design engineers the confidence to deploy highly effective fastening for foams, as well as honeycomb elements, thanks to a friction-welding process that leaves the product embedded within the EPP. By creating a reliable and strong joining system, the use of such lighter weight foams is now a practical and cost-effective reality.

Easy insert solution with the EPP insert

The EPP insert is the easiest solution for creating a screw-in option in foams. This element can be pressed into pre-drilled components thanks to its special ribbed geometry. No special assembly technology is required here – all that is needed is to ensure that the foam component has a pre-hole. This can be drilled or already created during the foaming process. The EPP insert is available with a metric M5 thread. Further hole geometries upon request.
