BIW (body in White) and CIW (cab in white) manufacturing programs of aluminium intensive structures typically selects Henrob as the supplier of choice for SPR. Henrob self-piercing systems are regarded as the bench mark in the industry because they offer very high levels of reliability in production and a history of zero parts per million rivet defects in service.
Automotive riveting is not a new concept, Audi pioneered high volume SPR in the early 1990's. SPR is still the first choice for Audi, Jaguar, Daimler and BMW when considering aluminium intensive vehicles.
Henrob's self piercing rivet is unique in the market place having been adopted across a range of automotive components not just Body In White (BIW), but Tier one suppliers commonly use a self pierce rivet in sunroof manufacturing and moon roof manufacturing. Henrob also have direct experience in designing and building turnkey robotic sunroof assembly cells.
Other common applications for the self piercing process include bonnet manufacturing (hood manufacturing), Boot and tailgate (trunk lid) manufacturing. Well know vehicle manufactures including Jaguar, Landrover, Daimler, Hyundai, Ford and many others utilise low weight closures, i.e. Bonnets, Hoods, Trunk lids, Boot lids, Doors, Window regulators, Sunroofs, Air bags assemblies, Seats, Heat shields and many other applications.
Hood, bonnet and trunk lid applications have even migrated down to smaller sized vehicles such as the Renault Cleo. Henrob’s involvement in the USA market is enabling greater penetration of SPR into that market for closures such as hoods but also for Cab in White (CIW) assembly lines in the truck industry.
SPR is not just restricted to the automotive industry. Henrob self pierce riveting is used across a range of transportation industries including buses and coach bodies, snowmobile chassis, boats, seating on aeroplanes A self piercing rivet can be used in trailer manufacturing assembling the roof to cant rail using an automated assembly station. A single trailer can have 100's of self-pierce rivets inserted into the structure.
Caravan manufacturing, and the recreational vehicle (RV) market uses Henrob self-piercing rivet (SPR) to assembly aluminium structural frames.
"Self-piercing riveting (SPR) has become an important alternative joining technique for the automotive applications of aluminum sheets. Most existing SPR machines use electrical motors to drive a rivet into the sheets. A significant amount of research has been conducted to improve an SPR joint's strength by increasing the mechanical interlock .......
Henrob | Self Pierce Riveting
Henrob is committed to pushing the boundaries of HSPR technology to new levels. Its philosophy - "an innovator not an imitator" - is realised in a corporate culture based on entrepreneurial and creative flair. We are extremely proud of having in our Henrob family the largest and most talented group of people solely dedicated to self-pierce riveting technology.
Henrob’s philosophy is to design reliable, robust solutions for production. This is achieved with the aid of 3D computer-aided design (CAD) software allowing in-depth modeling of tools and product access studies. Finite Element Analysis (FEA) software is used to ensure adequate life expectancy of components. Design data can be exchanged via the web, e-mail or FTP servers, offering rapid turnaround of rivet joint designs and equipment proposals.
Henrob applications engineers add fastening and assembly expertise to your technical team. After a careful review of your joint and installation needs, they will propose a complete fastener and tool specification suited to your application requirements and production environment. They may even suggest product design changes to allow more efficient assembly.
Whether developing a new product or streamlining assembly of an existing one, you can rely on Henrob's experience and innovation in fastening technology. From standard tools to customised systems, from rivet joint design assistance to automated assembly cells, Henrob can find your optimal solution.
Henrob fastening systems have benefited applications in a wide variety of industries around the world. View our case studies to see how we have helped customers cut in-place costs while improving their assemblies and finished products.
Henrob Self-Pierce Riveting (HSPR) is a cold joining process used to fasten two or more sheets of material by driving a rivet through the top sheet(s) and upsetting the rivet, under the influence of a die, into the lower sheet without piercing it.
