If you’re interested in a round duct making machine that’s not a spiral duct machine, here are some factors you might want to consider:

Machine Type: There are several types of machines used in the production of round ducts, such as plasma cutting machines, lock forming machines, and flanging machines. Each serves a different purpose in the production process.

Material: The type of material you plan to work with can influence the kind of machine you need. Common materials include galvanized steel, stainless steel, and aluminum.

Size: The size of the ducts you plan to produce will also affect your choice of machine. Some machines are better suited for large-scale production, while others are more appropriate for smaller ducts.

Budget: The cost of the machine is another important factor. Prices can vary widely depending on the type and brand of the machine.

Brand Reputation: It’s always a good idea to research the reputation of the brand or manufacturer before making a purchase.

After-Sales Service: Good after-sales service is crucial. This includes things like warranty, availability of spare parts, and customer service.

Remember to thoroughly research and compare different machines before making a decision. It’s also a good idea to consult with industry experts or professionals for advice tailored to your specific needs and circumstances.
