Henrob Self-PierceRiveting Technology(HSPR)

Our reputation as thepioneer of modern dayself-pierce riveting hasbeen built on providingcreative products andjoining solutions for ourcustomers throughoutthe world. We invite youto take advantage ofthis service.

How SPR Benefits Your AssemblySelf-pierce riveting is a process of joining two or more layers using an engineered rivet. Unlike

conventional riveting, HSPR does not require a drilled or punched hole. In terms of

product design and ease of integration into your manufacturing process, HSPR

is a very flexible system. Ensuring superior, consistent joint

performance, HSPR can outperform both conventional

riveting and welding.

Benefits over welding• HSPR can join dissimilar materials

• HSPR installation equipment is operator- andenvironment-friendly:– no cooling water or fume extraction is required

– no waste products are generated– noise levels are low, typically <80dBa

• Riveted joints can be checked visually for properfastening

• HSPR is compatible with adhesives and sealants,including layered sheets

• HSPR can be used on coated and painted surfaces,and will create better joints even on steel withthicker coatings of zinc

• Because HSPR is a cold form process, distortion dueto heat-affected zones is eliminated

Benefits of using self-pierce riveting technologies• Can fasten stacks of 2 or more layers;

current applications include up to12mm total thickness in aluminum and6mm in steel

• Will not damage coated or paintedapplications

• Provides repeatable joint strength

• Eliminates hole preparation

• Can replace expensive, multi-piecefasteners

• Provides superior static and dynamicload-carrying capabilities

• Because the bottom layer is not pierced,an HPSR joint can prevent the ingress ofliquids or gases through the fastenedjoint

HSPR Technology

Henrob‘s philosophy is to design reliable, robust solutions for production. Thisis achieved with the aid of 3D computer-aided design (CAD) softwareallowing in-depth modeling of tools and product access studies. FiniteElement Analysis (FEA) software is used to ensure adequate life expectancy oftools.

Electric servo and hydraulic systems are available. The size, shape andconfiguration can be engineered to place the fasteners quickly and

consistently. A lower-weight frame can be built toaccommodate pre-existing equipment.

Optional process monitoring equipment ensures proper,consistent placement with manual, pedestal orautomated assembly.

Many feed systems are available, including tape,mechanical cassettes and loose feed. Robotic placing

arms and process monitoringequipment can be integratedas needed.
