Class A: We collectively refer to it as a static problem
The so-called static state is the problem that lies quietly waiting for you to discover. For example, this channel has dead corners, that size is not in place, this temperature distribution is uneven, and so on.

Whether you find it or not, this type of problem is often the easiest to solve, as long as you observe and analyze it attentively, you can find the answer. Of course, this is only limited to people engaged in this industry's services, usually static issues. Most hot runner companies are already addressing some root causes.
For example, static problems rarely occur in well done hot runner companies, as years of experience have accumulated. Usually, such hot runner companies have better reliability, but often many hot runner companies encounter the same problems that are difficult to solve

Class B: we call it dynamic problem

Such problems arise in a changing way, and they are also high-level problems.

For example, now there is a set of hot runner mold that produces unqualified products, the hot runner glue is normal, and there is no static problem of the hot runner. At this time, this kind of problem can be called a dynamic problem. Some well-known foreign brands of hot runner companies will focus on developing solutions to dynamic problems.

Therefore, some of our customers said that the hot runner of the same set of products from abroad and at home will be different. If the foreign pressure is small and the product deformation is small, the product made is transparent, and the light transmittance is often good, the molding process is simple to adjust, and the size and processing accuracy can be guaranteed. The only difference is that the hot runner company that does well considers the dynamic problem before the hot runner, This is also the response to the dynamic problems that domestic hot runner companies must improve.
