Hello friend:
In fact, people who don't know how to buy equipment is like buying a lottery ticket? Find a supplier? I'm not sure if you're a good buyer or a good buyer. If it is not good, you can only change the manufacturer again in the next year.
I am in this business? I can teach a few small aspects. Equipment now quality are not much difference is only the service which is good and which is bad. Although they buy things is the buyer? But also try to make good relations. Good relations with small parts and small services people are embarrassed to charge. Service is two sides? Not unilateral. There are times when it's just a matter of listening to the good and the bad.
Secondly, when you buy the equipment, you should choose a bigger manufacturer. Their service will be perfect a lot.
You can go to Baidu to retrieve which ones are doing aluminum foil sealing machine to compare.? Now I found it is? Shanghai Yixing Packaging Machinery Co., Ltd. ranked first
Buy equipment not the highest price not the lowest price? The best way to do this is to get a good deal of money for your products and services. Low service cannot be guaranteed? Higher equipment are their own hard-earned money heartache.
This handheld device is good quality? You can consider it. The output is a little smaller? The price is also cheap? We can explore each other some time.
