Why Go Permanent?

Advantages of Permanent Part Assembly

We live in a world where things are put together. The computer you’re using, the desk it’s on, and the chair you are sitting in have all been assembled. At Orbitform, we specialize in permanent part assembly, processes like orbital forming, impact riveting, roller forming, and hot upset riveting and forming. These four processes are all unique and have their own strengths, weaknesses, and qualities. They have major advantages in assembling parts that don’t need to be taken apart, both in reliability and longevity. But what are they? Why do these processes excel when compared to non-permanent fastening solutions? If your product doesn’t need to be taken apart, consider these reasons to switch to permanent assembly.


  1. Reduce the Costs of Fastening Hardware

Leave behind the retaining rings, threaded fasteners, nuts, washers, and cotter pins. With permanent part assembly, the part and the fastener are formed together creating a secure and permanent bond without the use of extra unnecessary hardware.

  1. Reduce the Costs of Machining Operations

Save money by avoiding costly operations like machining grooves and threads, drilling and tapping holes, etc. With the time saved in these areas, quality and throughput is increased.

  1. Reduce the Costs of Assembly Operations & Cycle Time

It’s the easy solution when it comes to reducing cycle times: reduce the number of hardware parts and operations that need to be done to a part. This could be installing a retaining ring or cotter pin, or driving a screw or a nut. Permanent part assembly means shorter cycle times and more parts moved down the line.

  1. Superior Retention

Compared to cotter pins, retaining rings, and Loctite® adhesives, permanent part assembly has a much better retention level. There’s a reason the word permanent is in the title.

  1. Improved Aesthetics

If you’re concerned with how your finished parts look, permanent processes deliver some of the best aesthetics. As we mentioned earlier, lose the retaining rings and cotter pins; make it look clean and finished with a formed head instead.

There is not a “one size fits all” solution for permanent part assembly. But you could start receiving these benefits by switching your assembly process. If your product doesn’t need to be taken apart, for shipping, maintenance, or repair, then consider switching to a process like orbital forming, impact riveting, roller forming, or hot upset riveting. Orbitform is an expert in delivering unbiased approaches to help our customers find the very best process to fit their needs.
