• Die thread: Dies come in different threads, such as straight , metric, half inch NPT, and others. The die thread will determine the kind of hoses or fittings the machine can work with.
• Die profiles: Die profiles can be in the form of round, square, or custom designs, and they affect the shape of the crimped fitting. This specification is extra important for businesses that focus on aesthetics and precision.
• Die templates are similar to die profiles, but in this case, they follow specific patterns used in most industries.
• Crimping force: This is the force generated by the crimping machine, typically indicates in tons. It measures the strength of the machine to crimp fittings or hose that is force dependent.
• Power source: High-pressure crimping machines can be hydraulic, pneumatic, or electric.
• Voltage: This is the electric voltage the machine uses, usually AC 220V/380V or as specified for different models.
• Wattage: This is the wattage of the power output by the machine. It will determine the volumetric crimping capacity.
• Current: It is the machine's crimping current that determines how fast it can crimp a fitting or hose.

To prolong the usefulness of a high-pressure crimping machine, it is essential to maintain it correctly. Some maintenance practices include the following:

• daily cleaning of the machine to remove debris, dirt, and dust, preferably using a dry, clean rag.
• Lubricating all moving parts to prevent wear and tear.
• Storing in a dry, clean, and ventilated place when not in use.
• Inspecting for damages or signs of wear and tear and repairing or replacing any damages found.
• Calibrating the machine occasionally, especially after long use, to maintain accuracy.
• Reporting and fixing any hydraulic leakages if using a hydraulic machine.

Usage scenarios of a press for crimping high-pressure hoses

Crimping machines for hydraulic hoses are used in industries that manufacture, install, maintain, or use hydraulic systems and machinery. Such industries include the construction, mining, agriculture, oil and gas, marine, hydraulics service centers, and automation industries.

In the construction industry, high-pressure hoses are used in large construction machinery and equipment such as excavators, cement, and concrete pumps, among others. The mining industry also uses high-pressure hoses in the same manner as the construction industry, especially on equipment and machinery that operate under very high-pressure and high-temperature conditions. In the agriculture industry, high-pressure hoses are mostly used in specialized farming machinery such as those used for farm irrigation and industrial-scale farm equipment. The oil and gas industry mostly uses high-pressure hoses to transport crude oil and gas from extraction points to refineries. They are also used in specialized machinery and equipment such as pressure control systems, fluid power systems, and offshore drilling equipment.

The automation industry utilizes high-pressure hoses in automated factories and manufacturing plants. The same applies to the service center industry. Crimping machines are essential in these industries so that hydraulic hoses can have end fittings attached to them for those high-pressure hoses to function properly.
