How to Make Your Own Custom Molded Rubber Products

The basic reason for utilizing rubber seals is stopping liquid leakage between 2 joined surface areas. These are essentially mechanical seals which are used in static in addition to vibrant sealing applications. Rubber seals, made of natural rubber or artificial rubber, are made use of in numerous industries such as automotive, aerospace, building and construction etc. These seals are widely adopted in different applications as a result of functions like resistance to aging, fire retardation ability etc

. Rubber Seals Designs

There are different ranges of such seals readily available on the market on the basis of their styles, materials, usage as well as applications. There are 3 popular layouts of these seals and each style has its distinct random sample. Let us talk about these styles listed below:


As the name recommends, these are rounded O ring manufactures designed, in the shape of O or a doughnut. It has the ability to do a sealing activity by warping to take the form of the tooth cavity and also can conveniently suit it. It can be a static or a vibrant seal. In fixed securing, there is no or little activity in between the mating surfaces. In vibrant situations, a relative motion is seen in between the mating surface area. O ring has easy placing needs.


This design is in the form of the letter-X and also for this reason referred as X-rings. At times, it is also known as Q-rings. Taken into consideration to be a much better option to O-rings. Utilized generally in rotary seal applications. X rings provide double-closing activity. They have a four-lobed configuration which prevent the seal from being twisted. With two areas to be secured, they call for much less contortion to supply an efficient sealing.

Square Bands

These are seals with square random sample. Made of all-natural or artificial rubber, these are used primarily in high stress gasketing functions. Square rings are used in place of similar sized O-rings or other shaped seals. They are optimal for static applications but not for dynamic applications. Some basic benefits of square rings are regulated surface area smoothness, much better elasticity, correctly formed sides, and accurate firmness.

U-cup Seals

An additional preferred layout of rubber seal is u-cup seals. They are generally used for signing up with rods or rams. With tiny gland areas, they end up being all the more excellent. With U-shaped cross sections, self sealing is feasible for both their inside and outside diameters. There are three ranges of such seals.
