Rubber Rings Factory introduces rubber O-ring trimming methods:

1. Manual trimming. The operator holds the knife and gradually repairs the overflow along the outer edge of the product. This is the original method. The efficiency is low and the quality is difficult to guarantee. Especially for O-rings with small size and high precision requirements, it is difficult to be thorough and clean, and it is easy to damage the connection between the product body and the overflow. Tooth marks and nicks are often left, leaving oil and air leaks and other residual problems that affect the seal. In addition. The dependence of manual trimming on operational proficiency is also prominent.

2. Mechanical trimming. In order to improve efficiency and quality, mechanical trimming appeared. The most common is a special electric trimming machine with a rotating blade. The used blade A must match the height of the product size. If the inner and outer edges of the product have overflow. It can be designed as double-edged and multi-edged. To achieve one-time completion. The machining accuracy of mechanical trimming exceeds that of manual trimming, and the efficiency is also doubled. Especially for a multi-cavity product with a mold, a matching tool can be designed according to the arrangement and distribution of the product. After the product is out of the mold. The whole page can be put on, and the punching can be completed at one time. With the cooperation of heating, dozens of them can be repaired at a time. The key is that the punching temperature must be controlled well to prevent adhesion after being too high.

3. Freeze trimming. The vulcanized finished product and the waste edges are removed under freezing conditions. This technology was jointly invented and improved by Showa Carbonic acid in Japan and Zhaoling Precision in China. Over the past few decades, with the selection and replacement of freezing media and the improvement of mechanical action, the freezing trimming has also undergone several generations of improvements, and it has become mature and perfect. , Work efficiency and processing quality have been significantly improved.
