Ultimate Guide on How to Use a Crimping Tool

Hydraulic Crimping Tool – A core piece of equipment that is rarely seen by the public, yet underpins the unimpeded operation of the lifeblood of modern energy, transportation and industry. Specifically engineered to generate immense hydraulic pressure, it causes plastic deformation of metal conductors and connecting hardware (such as sleeves and terminals), thereby forming high-strength, low-resistance, permanent electrical or mechanical connections.

Most importantly, different categories of crimping tools are suitable for cables, wires, pipes and other workpieces of varying sizes or specifications. This paper explores the categories, types and operation methods of crimping tools.

Why Choose Hydraulic Crimping?

Compared with traditional bolted connections, welding or mechanical crimping, hydraulic crimping demonstrates overwhelming advantages:

• Exceptional Reliability: The formed connection features low and stable resistance with no risk of electrochemical corrosion.
• High Efficiency: Especially for large-section conductors, the hydraulic crimping speed is significantly faster than bolt fastening, making it a quick and straightforward process. Moreover, one set of tools can be equipped with a variety of dies to adapt to different working conditions.
• High Safety: It hardly damages the insulation layer or components of wires, and the crimped connections offer superior heat resistance, flexibility and vibration resistance.

What Types of Crimping Tools are there based on Application?

1.Battery Hydraulic Cable Crimper

Electric Hydraulic Cable Crimping Pliers are specially designed for crimping cable ends within the range of 400 mm². They are mainly used for crimping copper and aluminum wire terminals, and equipped with dies of different sizes ranging from 16 mm² to 300 mm².

2.Electric Hydraulic Press Tool

Hydraulic crimping tools are mainly used for crimping the joints of two pipes, and have become a standard process for pipeline installation in numerous high-standard fields such as building water supply and drainage, fire protection, and HVAC. For example, the SC-1550A is suitable for 12–54 mm [1/2″–2″] stainless steel pipes, PEX pipes, copper pipes and multi-layer pipes.

3.Battery Powered Hydraulic Hose Crimper

Air Conditioning Pipe Crimping Tools are professional tools specially designed for pipeline connection in air conditioning systems. Their core purpose is to achieve high-strength, high-sealing permanent connections between air conditioning refrigerant pipelines (mainly copper pipes), or between pipelines and components such as valves. The SUCA Air Conditioning Pipe Crimping Pliers are mainly suitable for crimping automotive air conditioning pipelines, drain hoses and sprayer hoses within 25 mm².

How to Use a Crimping Tool

In general, most crimping tools are extremely simple and easy to operate. However, the specific steps may vary depending on the crimping type, terminal type and crimping specification. Below, we take the most common cable terminal crimping as an example to illustrate.

Tools Required for Cable Crimping

• One crimping plier
• one wire stripper
• connectors (terminals)
• one cable
• one cable cutter

Operation Steps

1.Use a cable cutter to trim off the burrs at the end of the cable.
2.Strip the insulation from the cable (Note: Do not damage the solid conductors).
3.Install the terminal onto the stripped end of the cable and ensure that all conductors are fully inserted into the terminal.
4.Finally, place the wire terminal properly in the crimping tool and let the crimping pliers apply pressure to the joint. (Note: Select the crimping die of the corresponding size.)

Bottom line

There is a wide variety of crimping tools, but their overall operating logic is consistent. For most people, the process of using these tools is not complicated and can be easily mastered. We only need to select the appropriate crimping tool and crimping die according to different application scenarios to complete the crimping task effortlessly.
