Anti corrosion and corrosion resistant XOK imported rubber star ring
Anti corrosion corrosion of imported rubber ring star advantages and wide application
Size: diameter * diameter;
Executive standard: American Standard, Japanese standard AS568 JIS2401-P, JIS2401-G;
The hardness of the material: NBR70Black;
Use temperature limit: -40~120 degrees, -20~100 degrees; long:
Performance characteristics: resilience, good sealing, wear resistance, high temperature resistance, oil resistance; can work stably in different media, and long service life.  
Widely used: in gas or liquid medium, can be suitable for long-term use in a variety of static and dynamic environment. Star shaped sealing ring is generally installed in the outer circle or inner circle, the cross section of the rectangular groove is sealed. It is widely used in aerospace equipment, electronics, electrical appliances, agricultural machinery, sanitary ware, mining machinery, automobiles, watches, ships and other industries.
The performance advantages of imported Qingxing Ding ring:
1. imported Qingxing Ding type sealing ring with low density and high filling;
Anti aging ability excellent 2. imported NBR has been acclaimed as without cracking rubber;
3. imported NBR rubber star ring has good elasticity and compression resistance;
4., Ding rubber star seal ring is a good rubber sealing ring.
 
The soil resistance type circle trimming is divided into manual, mechanical and frozen three:
1. hand ring trimming soil resistance. The operator carries the cutter and gradually repairs the overflow edge along the outer edge of the product. This is the original method. Low efficiency and poor quality guarantee, especially for small size, high precision star ring is difficult to achieve, clean, and easy to damage the product body and the edge of the junction. Often leave teeth marks, gaps, so as to leave oil leakage, leakage and other issues affecting the seal. In addition. Manual trimming also depends on the proficiency of the operation.
2. mechanical resistance drops of oil ring trimming. In order to improve the efficiency and quality, mechanical trimming has appeared. A special electric trimming machine with rotating blade is common. The blade must be highly matched with the size of the product. If the inside and outside edges of the product are overflowing. It can be designed as double edged and multi blade. To achieve the completion of a single time. Precision trimming over manual trimming, efficiency has increased, especially for multi cavity products of the first mock exam, according to the arrangement and distribution of products, design tool and matching. After the product is out of mould. Can be set on the page, complete punching a. Under the coordination of heating, dozens of repairs can be made at one time. The key point is that punching temperature must be well controlled so as to prevent excessive adhesion.
3. frozen soil resistant ring trimming. The finished product, together with the waste edges, is removed in the freezing condition. The technology was developed by Japan's Showa carbonate and domestic Zhao Ling Precision joint invention improvement, for decades, with frozen medium selection, replacement and improvement of the mechanical action, frozen trimming has also experienced several generations of improvement, gradually mature and perfect, the efficiency and quality are improved obviously.
