Crimpers, Applicators, and Presses: 59239-4 Application Field and Working Principle

Crimpers, applicators, and presses are various types of machinery used in a variety of mechanical, electrical, and medical applications. Crimpers and applicators are tools specifically designed to tighten or apply cables, wires, and other material to each other in a secure connection. Presses are ball-point or hydraulic tools that utilize a mechanical or electric force to extrude or cut a material.

The 59239-4 specification is a standard developed by the International Electrotechnical Commission (IEC) to ensure the quality of components used in different electrical and mechanical products. It defines the requirements for crimpers, applicators, and presses produced for specified electrical and mechanical products. This specification is applicable to hand-held tools of all types, for both manual and pneumatic tools with crimping or pressing force greater than 0.5 Nm (Newton Meter).

Application Field of Crimpers, Applicators, and Presses

Crimpers, applicators, and presses are utilized in various industries, such as for electrical and electronics, automotive, aerospace, medical device, and telecommunications applications. For example, crimpers are frequently used in automotive and electronic applications, for joining wires, or for making an electrical connection. Presses are used for consolidating material, such as sheets of metal, or for cutting plastics. In medical applications, applicators are used to dispense drugs, and the presses are used in plastic injection molding for medical implants, such as pacemakers or other devices.

Working Principle of Crimpers, Applicators, and Presses

Crimpers and applicators operate on the principle of using pressure to join different components together. The pressure is applied by a plunger connected to a chamber filled with air or other fluid. As the plunger is depressed, the fluid or air inside the chamber is forced in to the component, creating a strong bond between the two pieces. Pressure is gradually increased as the plunger is further depressed until the desired bond is achieved.

Presses operate on the same principle, however, they use a more powerful force to cut or extrude materials. A ball-point press applies its force from a single location by a ball-shaped plunger. This plunger is forced downward onto the material, cutting or extruding a desired shape. Hydraulic presses utilize the same force, but instead of a single point, a number of cylinders working in unison are applied to the material.

Conclusion

Crimpers, applicators, and presses are essential tools for electrical, electronics, medical, aerospace, and telecommunications applications. The 59239-4 specifications developed by the IEC define the standards for the products of such tools. Crimpers, applicators, and presses operate on the principle of using either pressure or force to maintain an electrical connection, cut or extrude material, or dispense a product.
