The difference between swaging and crimping

Since our founding, we have supplied expert manipulation and bending services for tubing, supporting industries from across the country. One of our most recognisable skills is that of tube swaging. A rotary swinging procedure, we use it to manufacture circular concentric cutbacks at one or both tube ends.

Crimping and swaging are two processes that we utilise on tubes, particularly ones used for hoses. They do share some similarities, but there are certain differences that separate them. To understand how they work and decide which one we should use, we need to know what the contrasts between them are.

An exterior swage incorporates a ferrule that’s transported through a reducing die that’s normally split. Professionals do this to bring down the ferrule OD to a preset size. Afterwards, the hose tube is thrust down into the stem serrations. Crimping is where we generate a metal ferrule or sleeve of the hose attachment via an encircling succession of die divisions. We do this to compress the hose using the fitting.

What is the main difference?

The rudimentary distinction between the pair is that swaging begins at the edge that’s nearest to the hose. As it approaches the fitting, it starts to minimise the ferrule. It halts around three quarters of the way up the ferrule and fashions a bell section, producing a bell pocket, which the surplus hose can flow into.

During swaging, a mechanism forces a ferrule and fitting past a secure split die bed, whereas crimping employs various segment dies. Additionally, the crimping process restyles the makeup of the total circumference and length concurrently. It also demands considerably more energy to lower hefty wall ferrules at the same time.

At Multiform Tubes, we don’t limit ourselves to using just one type of tube. Instead, we prefer to use various kinds tubing materials in our endeavours. This includes brass, copper, titanium, and stainless steel. We can work effectively with all of them, providing excellent services such as our tube swaging, bending, and other manipulation techniques.
