HENROB Ltd

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.

Henrobs 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 Henrobs 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.

Speed and quiet operation are features of each system. Typical riveting cycle time ranges from 1.0 to 4 seconds.

HSPR has a number of advantages over other joining techniques, such as welding and blind riveting:

Joins a range of dissimilar materials such as:
Steel
Aluminium
Plastics
Joins multiple material stacks
Non-thermal process, can be used after coating or painting with virtually no asthetic or other damage
Low energy demands
Fast cycle times
Operator and environment friendly; no heat, fumes, sparks or waste
Repeatable quality
Visually checkable joint
Compatible with adhesives and lubricants
Automatic rivet feed allows continuous production
