What is a Crimping Tool and How Does it Work?

A crimping tool, also known as a crimp tool, is a hand tool with the help of which two pieces of metal are conjoined. The joining of the two metallic pieces takes place by means of deformation of either one of the metals or both the metals that are to be conjoined. The resultant joint is known as a crimp. An electrical connector, as the name suggests, is a device that is used for joining electrical circuits temporarily or permanently; it consists of a male-ended plug and a female-ended jack.

What is the Use of an Electrical Connector?

The use of an electrical connector can help join either wire of varying lengths together or electrical terminals to wires. Crimping is extensively performed in the metalworking sector for a wide array of applications ranging from affixing bullets in their respective cartridge cases to securing lids on cans of food made of metal. A good quality crimp is not that easy to make and mandates that you buy crimping tools only from standard manufacturers.

Most Common Crimping Errors Which You Must Need to Avoid 

Here are a few of the most common crimping errors and steps that will help you avoid making them:-

  1. The most common type of crimping error is that pertaining to the height of the crimp at the wire barrel section. The value of the crimp height should be well within the permissible range. This is very often caused by abrasion. If the crimping tool is loose, the crimp height at the wire barrel section may have a discrepancy in it.
  1. A lot of times, the presence of a gap between the barrel and the exterior diameter of the insulation of the wire, results in an improperly crimped wire which is, further, not even secured in its position. As with the crimping anomaly discussed above, this crimping error, too, results from either the abrasion of the crimping tool, looseness in the tool or from the use of an errant wire.
  1. Many times, the crimping is faulty or not up to the mark because of a number of reasons—from the partial insertion of the conductor, insertion of the insulated cover of the wire, and forceful extraction of the conductor out of the wire to over stripping of the wire. These can be avoided by inserting the conductor completely into the barrel, ensuring that the length of stripped wire is as per the permissible standard length.
  1. Lastly, many users often complain that the ratchet of their manual crimping tool cannot be released despite the handle being closed to the maximum extent. This can be taken care of by ensuring that the crimping tool is working perfectly fine—there shouldn’t be any deformities whatsoever in the ratchet or the springs of the tool.

Final Words About Most Common Crimping Errors

The key to perfect crimping lies in not just adhering to the aforementioned instructions but also buying from reputed manufacturers of crimping tools; some of the most renowned manufacturers of crimping tools are Dowells, Jainsons, Multitec to name a few.
