Clinching, also known as press joining, is a process (bulk-sheet metal-forming) which aims to join thin sheets of metal without involvement of additional components such as bolts, rivets, nuts and screws and uses special tools to form an interlocking system between two or more sheets. This process has no temperature requirements as such and can be carried out at room temperatures; however, in some cases, the sheets to be interlocked can be heater prior to the process in order to improve the ductility of the material. The technology of clinching is a result of the advent and development of industrial engineering. A dye and a punch are the tools used in clinching.
The intensity of pressure coupled with shape of the clinching tool helps to determine the mechanical interlock of the materials. Clinching machines are appropriate to fasten a wide range of ductile material like low carbon steels, aluminium alloys, copper. Their suitability also extends to materials such as magnesium alloys, titanium alloys, high strength steel and also polymers, wood and metal hybrids and so on. It can also be applied on metals with their surfaces coated, for example, plastic-coated, galvanized metal sheets and pre-painted metal. Clinching tools are used in clinching process to join metal sheet without using welding or fasteners and by joining the material of the parts itself. Clinching accessories are additional equipment along with tools used in clinching.
There are different clinching tools such as round joint flanged punch, round joint flanged die, round joint die, round joint flat die, offset die, twin point flanged punch etc. There are different accessories which complete the clinching tool set. Few of them are springs, holding flange, strippers, hexagon socket and open end wrench, tool checker (for monitoring the process and condition of the clinching dies), measuring equipment (to measure and control the dimension) and spray equipment (for lubrication). There are main two categories of clinching tools namely, static clinching tools and mobile or wireless clinching tools. Clinching tools and accessories should be selected carefully with respect to the type of material being clinched, its thickness and overall needed aesthetic appeal.
Clinching Tools and Accessories Market: Drivers
The factors that are driving the clinching tools and accessories are related to the popularity of the process of clinching. The tools are accessories are a major component of the clinching system without which the process cannot be carried out in the required manner to achieve the anticipated results. Moreover, tools and accessories form two sides of the same coin. Without accessories, tools are incomplete, be it tool maintenance accessories or tool carrying accessories, and they are of utmost importance. To give an inkling, more the usage of tools more are the accessories associated.
The clinching tools are adopted owing to increased adoption of the clinching technology in various industries due to its various advantages. The technological developments have raised the bar of the machinery equipment and accessories. This has helped manufacturers manufacture more sophisticated tools and accessories for clinching making them a vital aspect in the clinching market.
