What crimping dies are

To understand what crimping dies are and what they are used for, it is necessary to consider the meaning of crimping and how it is performed. Crimping is a common operation in wiring that involves connecting a cable to its termination or connector. The union is both physical, as the cable is joined to the destination element, and electrical since once the connection is correctly established, the passage of electric current (or data) can occur. To perform the crimping operation, a specific tool is needed, namely a crimping plier, which requires dies placed at the ends to work: it is precisely the dies that come into contact with the cable and the element to be connected, allowing the crimping to happen. On the plier, the dies must always be positioned in pairs, respecting the correct placement and carefully inserting the locking pin to secure their position.

The crimping dies are accessories that must be added to a dedicated plier and vary depending on the type of crimping to be performed: there are indeed different types, and choosing the right one depends exclusively on your needs and the material to be crimped.

How crimping dies work

But how do crimping dies work? All dies, once applied to the plier, allow the crimping operation through a mechanical squeezing that holds the cable on the connector due to the pressure applied. If the plier and dies are used correctly, the mechanical squeezing ensures a good electrical connection. Often, however, crimping alone is not sufficient, especially in conditions where external agents (such as water or humidity) could compromise the connection: in these cases, soldering with a tin alloy is also preferred.

Once crimping is done, the connection is irreversible and it is no longer possible to detach the cable from the previously connected connector. Also, crimping pliers (or presses) are not all the same but have differences: for example, the crimp profile (oval, hexagonal, trapezoidal, etc.) can vary, and some models are designed to crimp specific materials or work under certain voltage ranges (e.g., pliers ideal for connecting non-insulated joints or working within specific electrical voltage intervals). As already mentioned, we always recommend consulting an expert before purchasing to be sure of making the right choice.

Types of crimping dies

Let’s analyze in detail some types of crimping dies:

• Crimping die for pre-insulated ring terminals: these are dies for ring terminals and end connectors. They can be used for cables with sheath and differ by crimping ranges (expressed in mm²). They are generally used with pneumatic and/or electric crimping pliers;
• Die for bare terminals and ring terminals: these are similar to the previous ones, but the connection is with bare ring terminals. Usable with pneumatic and/or electric crimping pliers, differing in crimping ranges.
• Crimping dies for coaxial connectors (ideal for this type of cable). They differ by crimping range and profile shape.
• Crimping dies for flag fastons (pre-insulated and not) and dies for pins: specific dies for crimping certain connectors.
• Dies for pins and pre-insulated ring terminals: used for crimping both elements.

These are some common examples of dies, but many different types exist on the market, each specific to the connector to be crimped. In any case, it is important that these accessories are made according to precise safety standards to avoid unpleasant surprises or dangerous issues.
