Rubber to metal bonding is a means by which rubber is mechanically bonded to a metal insert during the molding process. To begin the bonding process, the inserts are first prepped for production using a degreasing system to rid the parts of any contaminants before the adhesive is applied. Next, the heat activated adhesive is applied to the inserts using a technique similar to spray painting. Once the metals are prepared, they are ready for production.

The inserts are then physically placed, one at a time, into each cavity of the mold. For inserts on the top of a part, special magnets are incorporated into the mold to hold them in place while the mold is being loaded. Also, for inserts being encapsulated into the rubber, special chaplet pins are incorporated into the mold to suspend the insert in the mold & allow the rubber to flow around the metal.

Once the inserts are in place, the normal rubber molding process commences. After the mold is closed, and the molding begins, the adhesive on the metals is activated, allowing the inserts to bond to the rubber.

Typical applications for rubber to metal bonding include, any part requiring the combination of the flexibility of rubber and the stability of a metal. Components ranging in size from small mounts for motors to large locomotive suspension parts are just a sampling of parts produced using this process.

In the calendering process, fabric and rubber material is passed through a series of rollers to flatten, smooth and commingle the two or more materials. Calendered sheets can have multiple layers of both the elastomeric and polymer sandwiched together.

Sheeting produced by the calender process is typically divided into two classes either fabric inserted, or unsupported. Unsupported calender goods contain only layers of rubber or plastic that have been joined without cord, cloth or textile being inserted for strength or tear resistance. Tire cord can be used special cases; rayon, cotton, nylon, or polyester cords are arranged in parallel and bound together by rubber on a calender.

Depending upon intended use and required look or feel, the sheets of rubberized fabric are then smoothed, glazed, polished, or given a moir or embossed surface. The resulting surface characteristics depend on the pressure exerted by the rollers, on their temperature, composition, and surface designs, and on the type of coating or glaze previously applied to the material to be calendered. Following the calendering process the material is then wound into rolls and placed into storage.

PTFE is principally used as a gasket material because of it's capability to remain unaffected by the majority of chemicals used in industry. It is also classified, in most cases, as a food grade material, making it acceptable to both medical and food production industries. There are three basic types of PTFE gasket materials. Virgin PTFE , filled PTFE and expanded PTFE .

Virgin PTFE is by far the least expensive of the three varieties, and is used in most general applications. Filled PTFE is a gasket material with a virgin PTFE base to which a substance is added during manufacture to improve the sealing characteristics of PTFE . This "filler" usually is glass or graphite particles although ceramics has sometimes been used. The resulting gasket material is strong, yet highly compressible with very good, though not universal, chemical resistance.

Expanded PTFE is virgin PTFE to which a stress resistance has been added by means of molecular rearrangement during manufacture. This process ensures that the molecular chains from which the PTFE is constructed, do not arrange themselves into set patterns. This means that expanded PTFE possesses no structural weakness (grain) and expands and contracts equally in all directions. Because no additives are required, expanded PTFE also possesses the unique chemical resistance of virgin PTFE .

Extruded rubber products will differ from moulded rubber products based on the process where extruded parts are forced through a die of the required cross section under pressure of an extruder. Often extruded products are unvulcanized prior to being extruded, leaving the rubber in a soft and pliable state post extrusion. If this is indeed the case, the finished extruded products will normally need to be vulcanized before they are rendered usable.

The extrusion process begins with the unvulcanized rubber compound being fed into the extruder. Next, the flutes of the revolving screw will begin to carry the rubber forward into the die, with an increase in pressure and temperature occurring as the material gets closer to the die itself. Once it reaches the die, the built up pressure forces the material through the openings, where it will consequently swell in various degrees based on the material compound and hardness. Because of this tendency towards swelling, many extruded parts require plus or minus tolerances on their cross sections. During the vulcanization, the extruded rubber will well or shrink in both its cross section and its length depending on the type of rubber compound used. After vulcanization, a length of rubber extrusion will tend to be reduced in dimension more in the center of the length than in the ends.

PTFE O rings are excellent resistant to acids, chemicals, steam, oils, bases, high temperatures, etc. Widely known by its brand name Teflon.

Silicone rubber has historically been used in specialty applications in order to meet requirements other elastomers cannot. Silicones have the largest application temperature span of all rubbers (-120 F to 500 F, with one or two exceptions where highly specialized and costly Fluoropolymers can compare). 

Their chemical structure allows Silicones to be the most benign of all rubbers in medical applications (again, the exception are some very costly Fluoroelastomers). Cytotoxity tests of Silicone parts made with simple formulations show no adverse effects. 

The US military applies the longest shelf life criteria to Silicone rubber components. For example, a coolant hose made with Silicone meeting SAE J20, is given a shelf life of 20 years, whereas those made with chloroprene rubber meeting SAE J20 are given a shelf life of 8 years. 

The benign nature of this rubber makes components made with Silicone ideal for electronic applications, where long life and chemical inertness are essential to good electrical integrity over the component’s life. Silicone rubber parts can be made extremely conductive (resistivity of 0.0001Ω cm) or highly insulative (resistivity of 1015Ω cm). 

In the automotive components market Silicone rubber has found major utilities in break line components, electrical grommets, radiator hoses, fuel line check valves (Fluorosilicone) and Oil Pan and Rocker Cover gaskets, as well as Spark Plug boots. It is estimated that in a modern car, 25% of the rubber components (excluding tires) are made of Silicone rubber

PTFE Sheets are typically of two types, namely Skewed PTFE Sheets and Moulded PTFE Sheets. Widely used in applications where high abrasion resistance is required, chemical resistance, high heat resistance, Oil & Acid resitance, etc.

It is also classified, in most cases, as a food grade material, making it acceptable to both medical and food production industries. There are three basic types of PTFE gasket materials.

Because no additives are required, expanded PTFE also possesses the unique chemical resistance of virgin PTFE .

Spiral-wound gaskets comprise a mix of metallic and filler material. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.

These gaskets have proven to be reliable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.

Spiral wound gaskets have proven to be the most reliable sealing element for use in difficult, critical and arduous duties. Spiral wound gaskets are used in Refinery, Petrochemical, Chemical, Steam lines and Process Industries, where they have many advantages over older types of gaskets.

These gaskets are manufactured to International specifications such as BS, API, ASME, DIN.

Lead rubber Sheets are manufactured using specific formulations with Lead as base and other speciality chemicals which in turn stops radiation penetration. This Compound is specifically Researched and Manufactured by Vishal Rubber Technologies Pvt Ltd. 

Lead Shielding - Lead Metal is a primary material for Radiation Shielding. Lead is highly effective Metal in providing protection from various sources of radiation and has become a standard in the design of Radiation Protection systems. Its density makes it one of the preferred materials for high energy radiation applications; X-rays, gamma rays and other nuclear radiations.
Theoretically, almost any material can be used for radiation shielding if employed in a thickness sufficient to attenuate the radiation to safe limits. However, due to to its specific characteristics discussed below, Lead is among the most commonly used material. The choice of the shield material is dependent upon many varied factors, such as final desired attenuated radiation levels, ease of heat dissipation, resistance to radiation damage, required thickness and weight, multiple use considerations (e.g., shield and/or structural), uniformity of shielding capability, permanence of shielding, and availability.
