Graphite manufacturing is not like steel manufacturing, graphite manufacturing cycle is very long, from raw materials to finished products, at least 6 months (half a year) of time, like wine, every a links, every a times must be strictly controlled, but inevitably there will be quality differences, even if the same batch of products, due to the location in the furnace, processing temperature will vary, resulting in different performance.
Usually, we will be tested to meet a standard section of the graphite products as a qualified product, of course, in the qualified products within the upper limit and lower limit of the product compared to the use of the performance of some of the differences, we will feel that any graphite company will have this kind of phenomenon, but the difference is not very big, also not often encounters this kind of extreme situation, if the customer has the request, we will try to provide the similar material in order to reduce the use error. The biggest difference between domestic graphite and foreign graphite is the extent of the difference.
