Working in a metallographic analysis laboratory for a long time, we have a lot of exposure to imported equipment, such as metallographic cutting machines, inlaying machines, polishing machines, hardness testers, and microscopes. As we are engaged in research work, sometimes the project schedule is tight and overtime is often required. We are afraid that the equipment may malfunction. Once a malfunction occurs, we need to contact the manufacturer's after-sales personnel for maintenance, replacement of parts, and so on, without wasting one to two weeks, Don't try to restore the equipment to normal. The worse situation is that once the parts are damaged and imported, most manufacturers may not have inventory in China. From placing an order to importing them, there won't be 2 months left to think about it. So that's what I'm afraid of.

    After working in the metallographic laboratory for so many years, the sample preparation equipment made by Americans is relatively good, but the after-sales service before was still not up to par. There was a failure of the metallographic cutting machine, and we had to wait for the parts for three months. Due to the shortage of after-sales personnel, after the parts arrived, we waited in line for repair for another two weeks. It was really helpless. No matter how anxious we were, it was useless for us to rush the project, I had to borrow equipment from other laboratories to barely complete the sample preparation task on time.

      In recent years, when purchasing imported equipment, we have included after-sales service as a key assessment item in the bidding conditions. The main equipment, such as metallographic cutting machines, inlaying machines, and polishing machines, are all imported from the United States. Last year, we directly purchased a set of equipment from supplier Nanjing Chain Energy. The after-sales service of Chain Energy is very professional and standardized. When signing the equipment procurement contract, Chain Neng added the after-sales service process as an attachment to the contract, conducting regular inspections and maintenance; Telephone guidance within 24 hours after the fault occurs; If it cannot be resolved by phone, the service engineer will arrive at the site within 48 hours; Commonly used vulnerable parts are available in stock.

      To be honest, although the contract states this and we can feel the sincere commitment of Chain Energy, there is still a shadow in my heart. I am also cautious in daily use and pray that the equipment will not malfunction. I don't know at what point there may be a problem, and I have to worry about getting angry again. I am really afraid of what will happen.

      Just a few days ago, we were rushing a batch of samples when suddenly the cooling water of the metallographic cutting machine couldn't come up normally. The cooling system of the metallographic cutting machine malfunctioned, my goodness! Quickly contact the after-sales service of Chain Energy. Well, the phone was immediately available. After listening to my detailed description of the malfunction, the service engineer instructed me on several operations and comforted me, saying, "Teacher, you don't need to worry. I will be in your laboratory tomorrow morning because there is a problem with the cooling circulating water pump. We will fix it for you as soon as possible and won't delay your work the next day. The stone in my heart finally fell to the ground. Sure enough, as soon as he started working the next morning, the young man arrived at the laboratory. After some tinkering, the machine resumed operation.

    This experience has made me admire the after-sales service provided by Nanjing Chain Energy! The teachers in the laboratory are very satisfied, and everyone agrees that the metallographic cutting machine made by Americans is good, and the after-sales service provided by Chain Home is better!
