Some issue for Choke Bean

Choke bean is an important part of positive choke. Though it is small and simple part, but there is some issue for it. During our working experience, we have some quotation from some America company for choke manifold. And every quotation just mention choke bean. It is same to our quotation. As we know, there is tungsten carbide in the choke bean. But recently, one commodity precious metals price is crazy recently, which is Co. Co is one of important component of WC. Co’s international price is double of end of last year. So choke bean’s price will be nearly double of last year. And choke bean’s price affect choke manifold price. One of our customers just bought some choke bean two months ago, and we feel that he is so lucky.

Maybe some customers search quotation from other supplier, the price will be keep the same with last year. The reason is that they shorten length of tungsten carbide. So the life of choke bean will be shorter. If end user insists us to do this, we also can do it. But please don’t think that our price is extra higher than other’s.
