Fluorine rubber o-ring manufacturers trimming into manual, mechanical and refrigeration and other categories: 1. Manual trimming. Operator hand tools, along the outer edge of the product, the overflow edge to gradually repair. This is the most primitive way. Low efficiency, quality assurance difficult, especially fluorine rubber o-ring size is small, high precision O-ring is difficult to do a thorough, in the net, and it is easy to damage the body and the connecting part and product overflow edges. Often leaving teeth marks, nicks, leaving oil spills, leaks and other problems affecting the seal of the aftermath. In addition. Hand trimming operating proficiency dependence is also very prominent. 2. Mechanical trimming. In order to improve efficiency and quality, there has been a mechanical trimming. Common is dedicated with a rotating blade electric trimmer. The height of the blade used to match demand and product size. If the inner and outer edges of the product have overflow edge. Can be designed as a double-edged, more cutting edge. In order to achieve a complete. Mechanical trimming precision than manual trimming, efficiency has improved several times, especially in a multi-cavity mold for the product concerned, in accordance with the arrangement and distribution of products, designed to match the tool. Be fluorine rubber o-ring product after the mold. Can put a full-page, once completed punching. Under heating with, one can repair dozens. The key is punching the temperature must be controlled, prevent the excessive adhesion. 3. Frozen trimming. The vulcanization good product together with scrap, were in addition to the side in freezing conditions. The technology was developed by Japan's Showa 昭凌 carbonated and domestic joint invention improves the precision for decades, with the freezing medium of choice, updating and improving the mechanical action, frozen trimming also experienced several generations of improvements, maturity and perfection work efficiency and process quality has significantly improved. In order to prevent twisting injury fluorine rubber o-rings, the design should note the following 1) O-ring mounting groove concentricity size, convenience and should not produce distortions to consider two aspects of processing. 2) O-ring section size should be uniform, and at each installation site should be fully applied in the seal oil or grease. Sometimes felt ring can also be used lubricating oil soaked refueling device. 3) increase the cross-sectional diameter of the O-ring cross-sectional diameter dynamic seal with O-ring should generally be greater than the static sealing O-ring; In addition, O-rings should be used to avoid the large diameter of the piston seal. 4) at low pressure also distorting damage, use protective seal retainer. 5) reducing the cylinder and the piston rod surface roughness. 6) the use of low friction coefficient material O-ring. 7) fluorine rubber o-ring is not easy to produce distortions manufacturers available to replace the O-ring seals.
