Punching Machine

When buying a duct corner punching machine, there are several factors to consider:

1. Model and Pressure: The model of the machine and the pressure it can exert (measured in kilonewtons, or KN) are important. For example, the J23-25T model has a pressure of 250 KN, while the J23-40T model has a pressure of 400 KN.
2. Dimension of Die Holder: This is the size of the die holder, which can vary depending on the model.
3. Slider Stroke and Stroke Times: These refer to the movement of the slider (the part of the machine that delivers the punch) and how many times it can stroke per minute.
4. Power: The power of the machine, measured in kilowatts (kW), is also an important consideration.
5. Dimensions: The overall size of the machine (length, width, height) can be a factor, especially if space is limited.
6. Brand and Manufacturer Support: Consider the reputation of the brand and the support offered by the manufacturer. For example, Artizono offers professional purchasing advice and can customize models according to customer requirements.
7. Safety and Ease of Operation: The machine should be safe to use and easy to operate.
8. Additional Features: Some machines come with additional features like a servo feeder for automatic feeding.

Remember to always consider your specific needs and circumstances when choosing a duct corner punching machine.
