分瓶螺桿：將欲套標瓶做等距分開，進入帶瓶組。

分瓶螺桿的常用材質有三種：種，國產POM和進口POM材質，常用的為國產POM材質，優點是成本較低，特性是不易變形，自潤滑性能高，不會劃傷瓶子。進口POM特性屬于國產POM加強版，但是成本較高，所以大多數人設計師在非必要情況下還是選擇國產POM材質。

第二種，MC尼龍材質，成本與POM相差不大，常應用于沖擊力較大需要耐沖擊的環境，特性是耐沖擊、耐刮擦，自潤滑性能好，耐磨，有些朋友遇到分瓶螺桿經常斷裂的情況下，可以嘗試使用下MC尼龍的材質；

第三種，PE材質，PE的成本方面跟前面兩種相差不大，分瓶螺桿行業里用的比較少，PE材質的特性就是耐磨，很多朋友反映分瓶螺桿由于磨損較嚴重需要經常更換，建議可以試用一下PE材質的分瓶螺桿。

Bottle-separating screw: Separate the standard bottles to be set into equal sets and enter the group with bottles.

There are three commonly used materials for bottle splitting screws: the first one is domestic POM and imported POM materials. Domestic POM materials are commonly used. The advantages are lower cost, characteristics are not easy to deform, high self-lubricating performance, and it will not scratch the bottle. Imported POM features belong to the enhanced version of domestic POM, but the cost is higher, so most people choose domestic POM materials under unnecessary conditions. 

The second type, MC nylon material, has the same cost as POM. It is often used in environments where the impact force is large and needs impact resistance. The characteristics are impact resistance, scratch resistance, good self-lubricating performance and wear resistance. In the case that the bottle screw often breaks, you can try using MC nylon material;

The third type, PE material, the cost of PE is not much different from the previous two. The bottle screw industry is less used, and the PE material is the largest The characteristic is wear resistance. Many friends report that the bottle split screw needs to be replaced frequently due to severe wear. It is recommended to try the bottle split screw made of PE material.
