 It is important for molded rubber products to have certain standards. O-rings are no exceptions and there is something called an Aerospace Size Standard for O-Rings AS 568. It is a US standard for O-rings that came into being by the Society of Automative Engineers (SAE). As per this system, a dash “-“ is used to refer to O-ring sizes that are standardized. 

The main benefit of having standardized system is that the engineers can make use of the standard O-ring sizes to build prototypes and test their designs. They would know the size of standard O-rings and they would not have to measure it every time. This brings a sense of uniformity. The Aerospace Standard mentions the cross-sections, inside diameters tolerances and size identification codes for O-rings that are put to use in sealing applications. Talking about the uses of custom molded rubber products like O-rings, they are used in the manufacturing world extensively.  The biggest use of o-rings is that as an oil seal.

 You must note that you can get standard O-ring sizes in different materials. The most common materials used to make o-rings are Nitrile, Neoprene, Butyl, Silicone, Fluorosilicone, Fluorocarbon, and EPDM. 

AS 568 is Aerospace Size Standard for O-Rings to help engineers build prototypes and test designs. O-rings are used widely in the manufacturing world.

Industries require a lot of products to meet their requirements. There is a huge list of tiny products without which things would come to standstill. A few of them are molded products.

When you talk about molded rubber products, gaskets and seals would come to the mind. They may seem to be similar but the truth is that they are little different from each other. The main difference between gaskets and seals is that while you use a gasket to seal components that have a flat surface while seals are meant for surfaces that rotate like engine parts, shafts and pumps. Gaskets are for components that are static whereas seals are for parts that rotate.

Also, seals are round and flat whereas gaskets come in different shapes.

Gaskets are used in transportation, electricity generation, oil and gas and paper and pulp industry. 

Though gaskets and seals may look like ordinary products, they are very important. Just imagine how your vehicles would run when there are no seals for the engine to function. The whole automobile industry would come to a standstill without seals. This indicates that no matter how insignificant a product looks; at times you can’t do without it.

There are other molded rubber products as well and they are timing belt and O Rings. 

A gasket is meant to seal static components whereas a seal is ideal for surfaces that rotate such as engine parts. 

 Rubber products have an important role to play in everyday life. Some of the important ones are oil seals, vibration mounts, conveyor belts, AS 568 standard O rings and rubber sheets. 

Talking about conveyor belts, you must have come across a conveyor belt while waiting at the luggage area at airports. 

There are mainly 3 types of conveyor belts namely, 

•Basic belt

•Snake sandwich belt

•Long belt

A basic conveyor belt comprises of 2+ pulleys and it can be used manually or with a motor. The items placed on the belt move forward with the forward movement of the belt. They are also used in packaging and parcel delivery utilities as they make movement of goods from one place to another quite easy and effortless.

A snake sandwich conveyor has 2 separate parallel belts and is used to move goods up an inclined surface. This type of a conveyor as created in 1979 and is used widely till date.

A long belt conveyor has 3 drive units and is mostly used for sending goods over a long distance. The main use of this kind of belt is in the mining industry and construction industry.

 All the types of conveyor belts have their own usage and make it easy for people to move goods from one place to another. 

Conveyor belts are used to move goods from one point to another. There are mainly 3 types of conveyor belts – the basic belt, snake sandwich belt, long belt.

There are so many industrial products that help us in our day to day life that we are not able count them. The ones that belong to that category arecustom molded rubber products. 

The most commonly used custom molded rubber products are gaskets and seals, O rings and timing belt. In fact, a lot of things wouldn’t be possible without these products. 

To manufacture custom molded rubber products, there are 3 commonly used techniques and they are the following:

1) Compression molding – For this technique, uncured rubber is used. It is placed in a mold and compressed with the help of heat and pressure. The result is a finished rubber product that is ejected from the mold.

2) Injection molding – This process has been in use since 1960. In this process, pre-heated rubber is injected into a readymade mold with the help of pressure. After the curing is done, the rubber leaves the mold and is ready for use. 

3) Extrusion – Extruded rubber products are put through a die that gives them a tube-like shape. This process is used for rubber pipes and hoses.

The applications of custom molded rubber products are really wide but it is important that they are manufactured properly. 

Custom molded rubber products are manufactured using 3 commonly used techniques that are compression molding, injection molding, and extrusion. The products have a wide number of applications. 

There is a huge demand for different types of products in the manufacturing industry for different purposes. The same applies to molded products. Also, there is the need for a number of products that are made using rubber to metal bonding.

To begin with, there are 3 important elements of a rubber metal bond and they are the rubber, bonding agents and the substrate.

Moving on to the process of rubber to metal bonding, it has the following steps involved
•Elastomer preparation
•Surface preparation
•Primer

•Adhesive application
•Molding
•Testing

Products made using rubber to metal bonding are widely used in different industries. The main use includes shock absorption, reduction in vibration, friction dissipation, sealing, noise reduction and the like.
The industries where these products are used are the following:

•Aerospace
•Automotive
•Construction
•Electrical
•Industrial machinery
•Medical
•Plumbing
There are many different molded products that are put to industrial use and one of them are fabric reinforced hoses.

It is all the more important that the manufacturers of the molded products put in efforts to make the products so that they serve their purpose well and meet the requirements.

Rubber to metal bonding is a procedure involving several steps. The products made using the process are widely used in different industries such as medical, aerospace, automobile and construction to name a few.

There are many rubber products that are found in all around us and we don’t know about them. The oil seal is one of them. They are rotary shaft seals and their main purpose is to seal the gap between fixed and moving components. 

Oil seals prevent the lubricant from escaping therefore there isn’t any contamination via the opening. In other words, oil seals function as a physical barrier to keep the lubricating oil in its place and prevent its leakage. Also, external bodies like dirt can’t enter the system when there is an oil seal. 

Oils seals are of several types and materials based on what they have to be used for. The choice of material depends on the application for which the oil seal is to be used. The applications include domestic equipments, automobile, industrial pumps, power plant equipment, turbines used in aircrafts and compressors. 

O-rings are widely used as seals. AS 568 is a standard for O-rings from the Society of Automotive Engineers. It is SAE that specifies the standard sizes of o-rings.

Other important rubber products used widely in various industries include vibration mounts, conveyor belt, and rubber sheet. When they are of top quality they can serve the purpose well.

Oil seals are used as a physical barrier to seal and prevent the leakage of lubricant oil and keep it in its place. They are used in several industries. 

Rubber products of different types are needed to meet the requirements of different industries. Custom molded rubber parts are affordable and last for a longer time period but you must keep certain things in mind prior to choosing the product and they are the following:

Is it durable?

When a rubber part is not durable, it cannot fulfill the requirement. Therefore, while choosing a product, you must make sure that it can function for a longer time period. It has to serve the purpose precisely. You must choose the material based on how well suited it is for the application.

How is the performance?

When the custom molded rubber parts do their work well, they will naturally help in increasing the productivity and the profit you earn. Therefore, it is essential that you select the parts that perform well in every regard. You must choose the material that suits your requirements well.

This applies to all kinds of rubber products including o-rings, timing belt, gasket and seals. They will work well when you choose the ones made of the right material. It is completely based on the purpose for which you are using the molded rubber product. 

Keep the durability and performance of custom molded rubber parts in your mind before choosing them. They can go a long way in increasing productivity and profit.
