Crimpers, Applicators and Presses - Accessories are versatile items that are used in a range of applications from manual assembly, automation, automated testing and even production. The accessories are generally grouped into two categories; crimpers and applicators. Crimpers are usually light-weight hand-held tools that are designed to apply pressure onto the ends of various conductors or other objects to enable a secure connection, while applicators are typically designed to feed and manipulate specific components. This article will cover the general features and applications of these tools, as well as the different types of tools and their working principles.

1. Crimpers

Crimpers are used to join together two or more conductors, such as those found in cables, cords and wires. They use pressure to compress the materials tightly together, forming a secure seal. The connection produced is known as a crimp connection. Crimpers can also be used to form or bend specific shapes and are often referred to as tools such as ‘crimping pliers’. Today, these tools are used in a wide range of applications including industry and military, as well as in the telecommunications and medical fields.

Crimpers come in a variety of designs, but the most common type consists of a plunger that is powered by hand, electronically, hydraulically, pneumatically, or mechanically. The plunger exerts even pressure onto the conductor and a die attached at the bottom. The specific shapes of the die define the shape of the crimp connection. The dies can also be removed and changed in order to create different connections.

2. Applicators

Applicators and presses are used to apply force to a specific area in order to achieve a particular function. These tools can be used to inject, deposit, affix, join, or otherwise manipulate various materials. They are also known as applicator systems, as they typically consist of a base unit and various interchangeable parts such as feeders, guns, clamps, and motors. These tools are used in a range of applications from manufacturing processes to everyday installations.

The most commonly used types of applicators are pressure die casting machines, mould injection machines, thermoforming machines, and ultrasonic welding machines. Injection machines are typically used to inject plastic or metal into a mould in order to create a part or component. Pressure die casting machines use high pressure to cast metal into a mould. Thermoforming machines use pressure and heat to shape plastic into a particular shape, while ultrasonic welding machines are used to weld two or more pieces of metal together using vibrations and high frequencies.

3. Working Principles

The working principle of both crimpers and applicators relies on the principle of applied force. The amount of force required and the type of force used depend on the application and the materials being used. For example, in the case of cable crimpers, a light force is used to compress two or more conductors together. In the case of injection machines, a much higher force and temperature is required in order to inject plastic into a mould.

In general, most crimpers and applicators utilise a plunger system which is actuated either manually, electronically, hydraulically, pneumatically, or mechanically. Once the plunger is activated, it applies a certain amount of force onto the material, thereby carrying out the desired task. The plungers used in most types of tools are generally adjustable, allowing the user to exert the exact amount of force required for the application.

Conclusion

Crimpers, Applicators and Presses - Accessories are vital components for a range of applications, from manual assembly to automated testing. They generally use a plunger system to apply pressure and/or force onto the materials, allowing for a secure connection or forming of a component. The specific design and working principle of each type of tool varies, depending on the application and materials being used. However, the general principles of crimping and applicating still remain valid.
