Product Description
This is a multi-functional horizontal expander machine, which is one of the key equipment in the HVAC industry. The machine comprises a gantry, a balancing device, a control system, a servo motor, a gearbox, and other parts.
The main function of this machine is to friction the inner walls of balls and copper tubes so that the copper pipes and aluminum fins can be closely combin, making the fins uniform and firm and able to efficiently transfer heat and air for heat exchange.
It plays an essential role in the modern production of heat exchangers. The machine is affordable and can replace tools at a low cost, adapting to the production of different sizes. This design can effectively reduce the cost of use.
Horizontal expander machine Working principle
This machine expands metal tubes in a horizontal direction, so the core of the heat exchanger is usually put flat on the table, and the metal tube is put into the hole of the fin. (If your tube length is greater than 5 meters, then you need a longer metal rod.)
1. First, the top of the metal tube must be expanding. We provide this pneumatic tool for expanding copper tubes, which is designed to make it easier for the Expansion machine to clamp the metal tube.
2. Align the copper tube with the Expansion machine and press the start button. The machine will automatically complete all the expanding work. Because a servo motor drives this machine, it can accurately control the tube length, and the error will not exceed 0.2mm.
3. Workers can start producing the following heat exchanger core when they finish expanding all the heat exchanger tubes. The expansion machine doesn’t need to be shut down, as this machine is very suitable for indirect production.
The machine won’t consume electricity when it’s not working, and if it’s going to be stop for a long time, you can turn it off.

Horizontal expander machine advantage
- Intelligent control
This machine is PLC control and built with various operating modes. Whether you are debugging production or large-scale production, engineers can switch production modes with just one click, which is very quick and convenient.
- Stable quality output
Each tooth of the expanding rod is finished by wire cutting, and the excess parts and burrs are precisely polished. During the expanding process, the expanding rod and the copper tube do not come into contact, thus improving the production stability of the heat exchanger.
- Scientific design
This Horizontal expanding machine is ergonomically designed, so people won’t feel tired even after long-term work. Even a frail Asian woman can operate this machine smoothly.
- Application of multiple sizes
The geometric layout of this Expansion machine is very flexible, covering almost all sizes in the HVAC industry. For multi-size applications, you only need to replace a tool cheaply.
- Powerful power output
The gearbox has multiple sets of gear transmissions and speed changes, which can output a powerful torque. It can quickly expand metal tubes such as copper, aluminum, stainless steel, and titanium alloy.

The surface process of the machine
This tube expansion machine is modularly designed; all parts are manufactured independently and assemble it. This manufacturing mode can significantly improve production efficiency, shorten delivery time, and also provide more possibilities for the surface treatment of each part.
Therefore, our machine parts are processed using different techniques to treat the surface of the parts, such as the control cabinet, the gantry frame, the machine body shell, etc. These parts are painted using the baking paint process. This paint has a long lifespan; and it will not fade, and the metal plate will not rust.
We have applied a nickel plating process for some unique parts, such as gears, collets, etc.
In short, the appearance of this Expansion machine is very beautiful, and when you see this machine, you will like it.
If you’re looking for an Expansion machine to produce heat exchangers, condensers, or evaporators,
then our machine, which is driven by servo motors,
has Very low operating costs and high production capacity, making it very suitable for you. You can contact our engineers to get more details about this machine.
