2.1. Rubber Gaskets

Techvision is a leading, manufacturer-direct, one-stop source for all your Standardand Custom Rubber Gasket and Sealing requirements. Aside from our industryleading quality and service, Techvision handles all types and grades of rubbermaterials and employs all types of processes in order to get the job done right of

high quality, on time, and in the most cost effective way.

Why is the use of different processes important? Most fabricated rubber productscan be made through more than one basic process, but that doesn't mean that oneis just as good as another. In fact, we commonly work around "easier" ways to geta job done because, for instance, we don't want a customer to buy an expensivemold to get a few parts that could be done as die cut gaskets or extruding coupledwith secondary vulcanizing or machining operations. In other words, you don't haveto know whether the custom gaskets you need would be better manufactured asdie cut gaskets, extruded rubber seals, or molded rubber gaskets. Our technicalassistance is free, and our knowledgeable staff will consider all possibilities. Wethink you'll like how we do our job, and not having to worry about whether yourparts are a die cut gaskets or molded rubber, or especially whether or not they'llbe done right and delivered on time.

Of course, just as we don't approach your part requirements with a biased view onhow to fabricate it, we also don't favor any particular materials. In bothcases, our only bias is towards what works best for you, our customer (or at leastsoon-to-be customer...we hope). We won't try to sell you expensive fluoroelastomer rubber gaskets if your temperature and chemical resistancerequirements don't require it, and even if it does, we won't push a more expensive

variety like Viton®

(unless you insist) if a less costly alternative is available.

We have various raw materials in this category for different applications. Kindlycontact us for your requirements. These seals are machined as per precisiontolerances on CNC machines.

Wiper Seals

Rod wiper/scrapers effectively wipe and scrape the full 360º circumference of a

reciprocating rod. They are designed to remove road dust, dirt, ice, mud, weld

flash, paint and many other particulates from the rod surface.

They prevent damage to bearings, seals, packing, and rods, thereby reducing or

eliminating contamination of fluids in hydraulic systems.

Rod wiper/scrapers consist of a honed, double spiral,

wiping element of age-hardened beryllium copper

(Rockwell C 40 hardness) surrounded by a synthetic

rubber elastomer. It is designed so that the

beryllium copper element is distended from thefinal rod diameter. It is precision honed to an inner-

diameter tolerance of+/- 0.0005". The honing

process guarantees a true circle on the ring inside

diameter and provides a highly polished and knife

sharp edge. In operation, the beryllium copper ring

polishes the rod without damage to the rod's finish.

It is self-sharpening and does not oval, curve, or

feather.

Rod wiper/scrapers are found wherever hydraulic or pneumatic cylinders are used.

They have demonstrated their effectiveness on fork lifts, resistance welders, off-

road machinery, farm equipment, hydraulic presses, foundry machines, andaircraft landing gear.

2.4. Rubber Diaphragms

Techvision's rubber diaphragms are versatile seals used in a wide range of applications to

handle various fluids, air, and vacuum sealing and flow requirements. Our rubber

diaphragms are custom-designed and engineered to operate for specific pressures and

pressure changes, mechanical requirements, fluid interaction, and dynamic life.

Techvision's rubber diaphragms can be tuned for unique application characteristics through

component and material design, to optimize final assembly performance and cost

Rubber Diaphragms typically function

within the application by transmitting

pressure from one system to another

without exchanging media between the

systems. Techvision diaphragms can also be

designed with integrated valves designed

to seal up to a pressure threshold before

allowing for the system to vent (leak). We

offer 100% in-line computer controlled

pressure testing of diaphragms for critical applications.

RUBBER LINING APPLICATION PROCESS:

The process of rubber lining is divided in to the following steps.

1. Preparation of the base surface.

2. Preparation of rubber sheets.

3. Application of the rubber sheets on the metal surface.

4. Vulcanization

5. Testing & inspection

Surface Preparation:This is very important process for rubber lining. The surface of the metal must be free fromoil, paint, scales, rust etc. This is generally removed with the help of sand blasting/ shotblasting. After the surface is cleaned, adhesive or bonding agent is applied to surface. Twoor three coats are applied, as adhesion is an important process for rubber lining.

Preparation of rubber sheets: The rubber compound is manufactured as per the requirements after looking in to thechemical and other conditions of the process. Rubber sheets are made on calendar machinein different plies. Lining up to 6 mm thickness can be applied in single layer. If thethickness is more, it is applied in 2 or more layers. For pipes & fittings extruded rubber

tubes are inserted in the pipes.

Application of rubber sheets:Un-vulcanized rubber sheets, which are prepared on the machine, are applied on to theadhesive coated, half dried surface under slight pressure of hand or with a metallic roll aswell as with the help of various lining tools. We have to ensure that no air gets trappedbetween the metal surface and rubber sheet. Joints are made levels and joined with helpof knurling tools.



15

Vulcanization:By and large vulcanization is carried out in an auto clave. This is the process by whichrubber changes from plastic state to elastic state. The temperature and pressure dependupon the rubber compound and thickness of lining. Large size equipments, which are rubberlined at site, are vulcanized by open steam as well as by hot water curing, the temperatureis maintained to get the rubber cured and for this method special compound of rubber is tobe manufactured for this process.

Testing and Inspection:All the rubber-lined items must be tested before and after vulcanization. This is to ensurethat they are free from faults, which might cause failure of the equipment. Visualinspection in good light is carried out to check mechanical damages blisters and poor joints.There after spark test with a high voltage is carried out to check mechanical damages, pinholes, blisters and poor joints. Hardness test is must for rubber lining. Knocking test is alsocarried out by an experienced hand with the help of wooden hammer to check whetherthere is any poor bonding.

Protection of rubber lining equipments:

The vessel should be stored away from sunlight or it should be covered by tarpaulin or some,other device. This will avoid direct sunlight, which may affect the surface due to the

presence of ozone. The vessel should be filled up with water when not in use for longerperiod.
