O-rings compared with other types of seals

O-rings compared with other types of seals

- suitable for a variety of sealed forms: static seal, dynamic seal for a variety of materials, size and groove have been standardized, interchangeability for a variety of sports: rotary motion, axial reciprocating motion or combined movement (such as rotation Reciprocating combination movement)

Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media

By selecting the right rubber material and the appropriate formula design, to achieve the oil, water, air, gas and a variety of chemical media effective sealing effect. Temperature range of use (- 60 ℃ ~ +220 ℃), the fixed use of the pressure up to 1500Kg / cm2 (with the reinforcement ring and use) simple design, compact structure, easy assembly and disassembly

O-rings cross-section structure is extremely simple, and self-sealing effect, sealing performance and reliable.

As the O-rings itself and the installation site structure is extremely simple, and has formed a standardized, so the installation and replacement are very easy.

More varieties of materials

Can be selected according to different fluids: nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), neoprene (CR), butyl rubber (BU), poly Tetrafluoroethylene (PTFE), natural rubber (NR) and other low cost dynamic friction resistance is relatively small

O-rings double-layer mold structure, including the upper mold, the lower mold, the mold, the mold between the formation of a number of O-rings cavity, the upper mold, the mold has two,

Forming a first and a second set of molds, wherein the lower mold of the first set of molds is fixedly mounted on the upper surface of the upper mold of the second set of molds, the lower surface of the upper mold or /

Of the upper mold is mounted on the upper surface of the support block, in the upper mold and the next mold after the formation of the plastic for the free flow and interlocking with the O-rings mold cavity

Gap. And the upper mold of the first set of molds and the upper mold of the second set of molds are respectively electrically heated

Tube. And said second set of molds are respectively provided with a row of rollers on both sides of the mold.
