    Mr. Khera: (India)
    I am making eps beads for the lying bags. I am always exporting to the European market. The pre-expander machine from Northern Alliance Machinery Group is very good to use and the best advantage for me is that I can make very light beads, as low as 4kg per cubic meter. For the same volume bags, the lightest the eps is, the less material I use, so their machine helped me save a lot of money. I like their machine very much.

    Fernando: (Sri Lanka)
    I am from Sri Lanka, and thanks to Northern Alliance Machinery Group, I gained national award for making green building materials. EPS waste is always a problem for the environment in our country. People throw it everywhere or burn the waste and it polluted the environment a lot. After I bought machines of eps concrete wall panel line, I collected the eps waste and crush them and used it for making wall panels. People knew that I use eps waste so they sent the eps waste to my place. I am doing good things to help protect the environment, at the same time, I can save the cost and gain high profits. I am very glad that I have this line.

    Kareem: (Saudi Arabia)
    I bought a whole line of making 3D wall panels from Northern Alliance Machinery Group in 2017. In fact, I started to search machines of such panels since 2010. The 3D panel technology originated from Italy but the machines are too expensive. So I started to search it on Chinese market. I visited a lot of factories before I decided to buy from Northern Alliance. Facts proved that my decision is right. I got the whole line at a very reasonable price and I got my line running at the end of 2017. This is a turn-key project and we just prepared water and electricity. Now the machines are working very well and our construction project is proceeding smoothly.

    Mr. Mahesh: (Sri Lanka)
    I am from Sri Lanka and our country is surrounded by sea water so we have rich resources of fish. The fishes are exported to many countries. For the packing of fish, eps boxes are the best so we always have very good business. We started making our first box with a small semi-auto machine and the productivity is very small. But now we expanded a lot and we have 4 full-automatic machines, all for making fish boxes. Lidia gave a lot of after-sale support for the production. Whenever I have questions, no matter how late, she always reply to me in time. I am very thankful to her help. We will still grow our business in the future.
    Mr. Atef: (Egypt)
    Mr. Atef: (Egypt)
    Our first eps line was bought in 2004 from Northern Alliance Machinery Group. At that time, I was studying in the university and my father visited China and bought the line. Later our factory expanded little by little and now I am in charge of the factory. We bought new eps machines but we are still using the old one which we bought in 2004. I can prove that the machine has really a high performance-price ratio. I think German machines must be better, but if you want to save money and have a reliable machine, just go to Northern Alliance. By the way, I am from Egypt.
  • Mr. Sanghvi: (India)
    Mr. Sanghvi: (India)
    I bought the machine from Northern Alliance by chance. I was deciding to buy the machines from another supplier in that city, then when I was shopping in the mall, I happened to meet their salesperson Lidia. I visited their factory the next day and then decided to buy from them. To be honest, I chose them at that time because they gave me a lower price than the other factory. After my line worked, I found I made a right choice. Their machines works perfectly. My operator is a very experience person, he has experience of using eps machines from many factories. He told me the machine from Northern Alliance is very easy to use and maintain. And the product quality is really good. Our product densities have a big range from 4.5kg/m3 to 40kg/m3. The machine can deal with all without any difficulty. I am happy that I have their machine.
  • Mr. Hadley (the United States)
    Mr. Hadley (the United States)
    I have a trading company and I have bought 6 eps lines from Northern Alliance and then sold to African countries. I trust their machines very much because they have never caused me problems. Whenever I need help, they are always there to help me. The first time when I bought their machine in 2008, I went to their company to check the loading, but later, I didn’t need to go there at all. They did the work very well for me. And they also do very well for the onsite installation. Even if I am not in the buyer’s factory, I don’t need to worry at all. They also helped me buy other machines from other companies at good quality and a good price. I really appreciate it. We will have a long-term co-operation.
  • Mr. Lars (Denmark)
    Mr. Lars (Denmark)
    I am from Denmark and we are a company making lightweight concrete. We were thinking to use this lightweight concrete to make wall panels for our market. So we bought their wall panel molding machine. We didn’t ask for the onsite installation but they offered us very detailed explanation about how to install the machine. It is very helpful. We are now using the machine well.
  • Mr. Naizer (Saudi Arabia)
    Mr. Naizer (Saudi Arabia)
    I first came to know Lidia in 2009. And I didn’t buy the eps machine until 2017. During this time I did a lot of inspection and Lidia also helped me a lot in the preparation of all things. I am sorry when the machines were installed, it was our Ramadan and it took a long time. Now the machine runs very well and we will expand a new line for shape molding in the next few years.
  • Mr. Eldar (Uzbekistan)
    Mr. Eldar (Uzbekistan)
    I am a big fan of Northern Alliance. Our country needs a lot of eps blocks for wall and roof insulation and because of language barriers, few buyers can find the good machine suppliers. I have bought over 10 lines from Northern Alliance to our country. My customers are happy that they have good quality machines and good after-sale services, I am also very happy that I have a good profit. Before, I bought only EPS machines, in 2019, I bought my first XPS line. I am using it by myself now and also use it to show to our customers so that I can sell more machines in the future.
  • Mr. Babahani (Iran)
    Mr. Babahani (Iran)
    We are among the first manufacturers of eps blocks in Iran. We bought our first line from another Chinese machine factory in 2001. In 2005, I wanted to expand my factory and I needed another line. The first machine works well, but the price is too high so we bought our second line from Northern Alliance at a very reasonable price. The machine works very well until in the middle of 2019, Iran’s EPS market was not as good as before, we changed to a more profitable product and sold the machines to others. We helped the buyer with the installation. Although it is second-hand machine, it works well enough and our customer is satisfied.
