Company Brief

Our quality range of Inflator Seals is manufactured in a relaxed or deflated position like cycle tubes. When the air pressure is applied the seal either expands or rise in order to meet the sealing face. Further, when the pressure is released the seal returns to its relaxed position after which all seals are supplied with a one way inflation assembly in water seal production.

These Inflator seals provide on inflatable sealing solution where the risk of fabric contamination is not acceptable.

Advantages

• Provides a leak proof closure yet allows clearance when needed

• Simplifies the design of the structure & hardware

• Minimizes the need of close matching and fabricating tolerance

• It is not subject to compression set which negates effectiveness of other seals

• Western inflatable seal has very good inflation and deflation property on joint & nozzel

• Size of the seal is very accurate with tolerance of +5% can withstand 4 kg cm2 pressure

• Western inflatable seals are uniform so there is very less chance of bursting at recommended pressure.

• Leak proof property at joint & nozzel

The extensive range of Inflatable Seals is used in a variety of manufacturing and OEM application. These seals are ideally suited for applications, which require a positive pressure applied along a part, door frame and mold vacuum chamber. Some of the other application areas encompass the following:

• Printing & Doctor Blades

The fabric reinforced seal is a completely molded seal, which is built around the same operating as a homogeneous inflatable seal. The addition of fabric helps to increase the amount of internal pressure by which the seal can operate where higher pressures are required in a non-enclosed environment.

Several various conditions which merit the use of a fabric reinforced seal are to achieve higher pressures.

 

Depending on the conditions that the seal can encounter, we can use nearly any fabric available reinforce such as inflatable seal calendared sheet or rubber extrusion as per the client’s requirements. Some fabrics used will have limitation with regards to the thickness of the fabric that can be applied within the part and what temperatures a fabric can withstand during operation.

• Nylon

• Kevlar

• Polyester

• Cotton

• Fiberglass

The fabric reinforced seals are prone to over pressurization and can fail if not properly operated. Further. These seals can also fail if cut or if a hole is poked in to the side-wall of the inflatable cross section. Thus, for these applications we can supply the safe operating & installation guidelines. In many cases the use of a proper retention system for a homogeneous seal is employed to compensate for a high pressure requirement. With a proper retainer and seal design a homogeneous seal can often take advantage of a thicker profile which can stand up to the most extreme pressures.
