1. FKM O-ring rough edge is too large, in the production, often need to use the mold, after forming, need to pour out from the mold.In many cases, there will be burr after the fluorine glue O-ring mold, burr will greatly affect the quality of the product, in order to ensure that the edge is smooth, no burr, often need to use the edge machine or frozen packaging edge to deal with the burr.

It can be said that the pruning problem of the burr has become one of the problems that many fluorine glue O-ring manufacturers need to solve. Once the burr is too large, it will affect the appearance and quality of the product, leading to poor product sales.

2. FKM O-ring raw material problem, because in the production of fluorine rubber O-ring, raw material is a very important link.In many cases, the stretchability and resilience of the fluorine rubber O-ring produced are lack, not only because of the loose time control in the production process, but also because of the raw materials.

Many mechanical processing industry and fluorine rubber o-rings seal performance is higher, which requires the product of the material itself to have good sealing performance, in order to produce the high quality of fluorine rubber o-rings, the manufacturer will choose high thin silicon cuff links of raw materials, if improper raw materials selection, performance is likely to lead to the product can not meet the requirements of customers.
