WHAT'S THE FUNTION OF O-RING

What is the primary function of O-ring？

‌ The primary function of the O-ring is to provide a seal between two closely fitting parts to prevent the leakage of gas or liquid.

What is the working principle of O-ring？

The sealing principle of the O-ring is achieved by its elastic deformation within a properly designed groove, and when the O-ring is subjected to pressure, its circular cross-section becomes elliptical, thus closing the gap between the sealing or contact surfaces.

What is the main materials of O-ring？

O-rings are made of various materials, and you can choose the right material according to different working environments and requirements.The common materials include rubber, viton,EPDM and silica gel, etc., which have good pressure resistance and corrosion resistance, ensuring the reliability and durability of O-rings in various harsh environments.

What is the advantage of O-ring？

The O-ring section structure is extremely simple, and it has a self-sealing effect, and the sealing performance is reliable. In addition, the O-ring itself and the structure of the installation site are extremely simple and standardized, so it is easy to install and replace. And resistant to oil, acid and alkali, wear, chemical attack, etc.

O-ring repair method

The trimming of O-rings is divided into three categories: manual, mechanical and frozen

1. Manual trimming. The operator holds the knife and gradually trims the overflow along the outer edge of the product. 

2. Mechanical trimming. In order to improve efficiency and quality, mechanical trimming appeared. A common one is a dedicated electric trimming machine with a rotating cutting edge. The blade used should be highly matched to the size of the part. If there is an overflow on the inner and outer edges of the product. It can be designed as a double-edged or multi-edged edge. to achieve a one-time finish. The machining accuracy of mechanical trimming exceeds that of manual trimming, and the efficiency is also doubled, especially for products with multiple cavities, which can be arranged and distributed according to the product, and the matching tool can be designed. After the product is out of the mold. It can be put on the whole plate and completed the punching 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 well controlled to prevent adhesion after being too high. 

3. Frozen trimming. The vulcanized finished product, together with the waste edges, is de-edged under freezing conditions.
