Inflatable seals work by introduction of an inflation pressure into the cavity of the inflatable seals. This inflation pressure causes the displacement of the seals effecting a positive seal between the seals and the surface to be sealed. Once the seals inflation pressure is removed the seal returns to its uninflated position (memory). Regulated air is the commonly utilized inflatable seals medium while in some applications pnuematic (gas) or hydraulic (liquid) methods are suitable. Inflatable seals offer versatile configurations in three different planes: radially in, radially out, and axially. Inflator-seals are an inflatable silicone seal (like a door seal or aperture seal) that can be inflated to accommodate a variable sealing gap.

In India and globally does require high levels of design and quality control. At western we are capable to handle these needs. Our seals for the energy market (primarily nuclear power) typically consist of:Molded construction (rather than extruded) for near cross section tolerances fully molded configuration for our western inflatable seals (after cure joints that could be possible weak points and burn fabric )Fabric reinforcement for maximum structural integrity.Use of certified materials that have met the necessary radiation resistance testing.

Fluid bed dryer is well known and widely used equipment in pharma .it is used in granulation for drying the material desire moisture content in the tablet formulation granules fbd contains stainless steel chamber having removable perforated bottom known as bowl.as the flow of air by fan increases the fbd bag expand and powder start turbulent motion and material get dry .Fluid bed processing involves drying, cooling Of particulate materials. It is ideal for a wide range of both heat sensitive and non-heat sensitive products. Uniform processing conditions are achieved by passing a air through a product layer under controlled velocity conditions to create a fluidized state.

When the gap to be sealed between to rectangular surfaces having sharp corners or to seal two surfaces with irregular profile, in these cases customized moulded seals are used instead of the conventional extruded compression seals. The advantage of custom moulded seals is that dimension accuracy is well maintained specially around sharp corners or joints . Moulded seals shape does not deform at any spot in the seal. If its required to have a razor sharp fitting in an assembly that where moulded door seals are used.

Elastomers used for manufacturing Moulded door seals:-

• Silicone rubber has chemical resistance , FDA complianceand excellent elongation properties
• FKM has excellent chemical resistance andhigh temperature resistance
• Natural Rubber is seldom used because of itspoor aging propertiesexcept in cases where abrasion resistance is required.
• Buna N / Ntrile has good physical properties and excellentresistance to petroleum based fluids
• EPDM has very good weather resistance as well assteam resistance
• Chloroprene has good weather resistance andflame retarding properties

We can manufacture Moulded door seals in from5 Shore A hardness to 90 Shore A hardness

Western polyrub inflatable seal for isolator door is made from high strength FDA approved silicone rubber which inflate radially outward . Because the shell of the unit is fabricated due to less gape and not machined, the machined acrylic or steel door will be made to a much tighter tolerance than the frame. This means there will be a enough seal gap.western polyrub seal is made with 25 % to 50 % inflation which cover that gap with 2 kg pressure

Western polyrub silicone inflatable seal for use between the cover and base of a heat treating furnace. The seal includes an annular fluid-impervious member mounted on the base. brass Valves are provided to inflate and deflate the annular member. in the inflated position, the annular member extends between the cover and the base to provide a tight seal. The casing of the member is made of a metal or any other material, The use of bell-type annealing furnaces for heat treating coiled strips of material has become widespread in the art. These heat treating furnaces include a base of one or more pedestals on which the coiled strips of material which are to be heat treated are placed. An inner cover is placed over these coiled strips of material, and it is necessary in most instances to seal the coils within the inner cover to provide a controlled atmosphere therein.

what is dewaxing autoclave in the investment casting process, casting wax is injected into a metal die in order to create a solidified wax positive of the part to be cast. This wax positive is called a pattern. The wax pattern is then dipped in a ceramic slurry to form an external ceramic shell negative. Once the ceramic shell is created, a dewaxing autoclave is used to melt and remove the internal casting wax from ceramic shells. The ceramic shell is then fired and ultimately used as the mold cavity for the metal casting. The dewaxing process occurs in a dewaxing autoclave which lead is tight with silicone inflatable seal and typically involves a rapid pressurization to 85 psi (5.8 bar) and in some cases a gradual increase to 140 psi (9.6 bar). After heat up, there is a 15-20 minute dwell, and then a controlled depressurization at 15-30 psimin (1-2 barmin) in order to reduce the possibility of cracking the shells. Once pressure has dropped to 15 psi (1 bar), the wax is forced out of the dewaxing autoclave into a collection system using autoclave pressure which is controlled by inflatable gasket

Hydro electricity is the term referring to electricity generated by hydro power; the production of electrical power through the use of the gravitational force of falling or flowing water .Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the waters outflow. This height difference is called the head. western has developed and supplied inflatable seal to many turbine project

Western inflatable door seal is a reinforced elastomeric tube or without reinforced (depend on pressure)custom molded in a round concave, convoluted or flat configuration . It is designed to round out with the introduction of an inflation medium to form a tight barrier between a mounting and striking surface. When you feel air as per pressure(chk pressure data). the seal quickly expands to the striking surface, effecting a positive seal. When the inflation medium is removed, the seal retracts naturally to pre-inflated configuration. This position provides clearance for free movement of one or both surfaces.

Western high pressure Inflatable seals and loading tube solve a number of unique problems in the pulp and paper industry. paper manufacturing equipment is usually quite big. To control tolerances between mating pieces of equipment or to account for the thermal expansioncontraction of metal not possible when trying to use a conman seal like an o-ring.Use of an fabric reinforced inflatable seal in these instances would be able to take up these variations. Also, clamping large rolls of paper or pushing long doctor blades can be handled more easily with a western seal that can account for tolerance variations more easily than more traditional old methods.our quality is equivalent to seal master inflatable seal and pawling
