The Riveting

Riveting means joining two parts by rivets. There are many types of rivet: tubular, semi-tubular, solid, self-piercing... different materials: steel, aluminium, copper, stainless steel...and different riveting technologies.

The main advantages of the riveting

	Rivets join different materials: plastic to steel for example, painted or coated material, composite and even more. You can join more then two parts at a time.
	Mechanical joining is guaranteed, constant and joining quality is easy to assess; with welding for example, process quality can only be assessed by using sophisticated, expensive techniques.
	The riveting process is ecological, free of fumes, sparks, vapours, oils and so on..

	A thread insert, also known as a threaded bushing, is a fastening element inserted in an item to add a threaded hole. In general, it can be used to provide a more durable threaded hole in softer materials.

	The solid rivet creates a mechanical joint joining two or more sheet metal parts, metal ones in general. It is also used to join composite materials where welding cannot be used. It is not a removable joint as the mechanical approach is definite and can only be disassembled by removing the rivet itself. Capmac Industry uses this rivet to joint both pre-pierced sheet metal parts and as a self-piercing rivet which perforates sheets automatically.

	The tubular rivet creates a mechanical joint; this kind of rivet is usually used to assemble metal sheets or composite materials. It is not a removable joint: it is used when there is significant shear stress between the two parts to be joined. This type of riveting is particularly suited when one or both the materials is "soft": using a solid rivet, the stalk would swell and consequentially deform the plate. Using a tubular rivet avoids any deforming.

	Semi-tubular rivets are similar to solid rivets except for a partial hole at the tip. This hole’s purpose is to reduce application force needed by rolling the tubular portion outward. The finished look of a tubular rivet will be a head on one side and a rolled over, exposed shallow blind hole on the other.


	Blind rivets are tubular and supplied with a mandrel through the centre. The rivet assembly is inserted in a hole drilled through the parts to be joined and a specially designed tool is used to draw the mandrel into the rivet. This expands the blind end of the rivet and the mandrel snaps off. These types of blind rivet have non-locking mandrels and are not used for critical structural joints as the mandrels could fall out due to vibration or for other reasons leaving a hollow rivet that would have a significantly lower load carrying capacity than solid rivets.

Riveting Technology

PR technology means self-piercing rivets can be used to join two sheet-metal parts without pre-piercing them. There are several market solutions applying this technology, but in general they all involve using special patented rivets. click here
