Types of Rubber Molding

The process of rubber moldings has helped shape the way that we use rubber in today’s world. Rubber molding consists of shaping rubber into the desired shape. Sometimes the rubber is mixed with other materials to make the rubber more flexible, tougher, or resistant to UV rays and cracking. In general, there are three main types of rubber moldings that help create the rubber products used today.

These processes include: compression molding, injection molding, and transfer rubber molding.

Compression Molding: Compression molding is the simplest form of rubber molding. In this process, a sheet of rubber is placed inside a mold. The two halves of the mold are pressed into the sheet, forcing the sheet of rubber to take on the shape of the mold. This is one of the oldest forms of rubber molding, and it is also the crudest form of molding. Only the simplest shapes can work with this form of molding, and it often produces rubber pieces with errors in the final shape.

Injection Molding: Injection molding is the most precise way to shape rubber. In this process, the rubber is heated until it has a toothpaste-like consistency. The rubber is then injected into a mold and allowed to harden. Rubber pieces created this way are strong, unlikely to loose their shape, and retain the exact shape of the mold with few inconsistencies.

Transfer Molding: Transfer molding is somewhat of a mix between compression and injection molding. In this process, a large slug of rubber is placed into a pot. A machine forces the slug into the mold, which causes the rubber to take on the shape of the mold. Rubber pieces made this way have higher quality than compression pieces, but less than injection pieces.

Rubber, the Preferred Gasket Material

Whether your intention is to keep what is on the inside, in or what is on the outside, out; chances are you are using a gasket seal. There are many everyday uses for gaskets. We use gaskets to prevent our hoses, sink drains and pipes from leaking, and use them to keep the rain, ice/snow and other elements out of our vehicles to prevent damage to engine components and interiors. Since gaskets are typically keeping liquid forms from entering or leaving an area, it is essential that they are waterproof. This prevents rapid deterioration and alleviates problems in a system. EPDM, or Ethylene Propylene Diene Monomer, is one material that is used to make naturally waterproof gaskets.

EPDM, the preferred compound over natural or synthetic rubbers, was developed from a careful mixture of ethylene propylene and diene; EPDM acts as an elastomer as well as a polymer. This means that it is a measure of flexibility as a created substance; making it an excellent gasket. There are several shapes and styles that are created for the specific application that they will be used for. Gaskets that are designed to sit inside a nozzle for your hose to connect to the spigot to where water flows at a high rate of speed are called o-rings. Gaskets that are long and thin can be for the frame of the vehicle and its glass. Since gaskets are used to create seals, it is very important to use a flexible gasket to seal in water pipes and gas lines.

Believe it or not, EPDM gaskets are also the preferred gasket when it comes to high temperature applications. Not only is EPDM fireproof, it can be used in such environments like: industrial ovens or hydraulic systems that process high temperature chemicals or hot water. Since these forms of gaskets are so versatile in a variety of situations, it stands out as a highly sustainable strong material that can reduce the costs of other gaskets that fail due to rapid deterioration or poor compatibility.

Rubber Washer: For Wet Environments

An industrial washer and an industrial gasket are the same thing, although a washer made of rubber is only one type of gasket, which is particularly ideal for wet environments. Most rubber products now are synthetic, although there is a natural rubber substance that comes from the rubber tree. However, developing rubber in a lab is much easier as well as more prudent when creating products with specific chemical characteristics. The process of creating synthetic rubber allows for alterations to make the substance perfect for its application. Rubber is an excellent material for gaskets and/or washers for a multitude of reasons.

A rubber washer is shaped like a flat doughnut and is used as a seal in between various pieces of industrial hardware, such as with a flange combining two pieces of pipe or between a screw and the surface it is penetrating. Its thickness and size depend on the application. The rubber substance is water-proof, which is partly why it is a great choice for wet applications such as water treatment piping and medical applications involving fluid. Because of their durability, flexibility and water-proof characteristics they are used instead of metal gaskets for use in swimming pools, air conditioning systems, pressure washers, boats ad other applications where moisture is involved. Viton gaskets are a particularly popular type of rubber washer used on the market today.

Leaking pipes or tubing systems can be detrimental to the environment through which they are passing through as well as the employees who are in the area. This is particularly true in chemical processing plants and medical fluid tubing with patients. In this sense, rubber washers are vital to create an impenetrable seal to keep the substance within the tubes inside the tubes, which rubber washers are very good at. They can not, however, handle extreme temperature changes, which should always be kept in mind when purchasing a gasket for an application. Every material used to make washers have their upsides as well as their downsides.

Here at Reliant Rubber Company we manufacture and distribute top of the line rubber gaskets and other non-metal products. We do this through a number of different processes that leave behind excess rubber and material byproduct. We re-use and recycle the leftover material as much as possible.  If we are unable to use the material for in house

jobs then we donate the material to various organizations, schools and artists.

The leftover material is typically in the form of centers from gaskets and is able to be painted or cut.   By donating these materials to local organizations, schools and artists  within the community we are giving back to the community while also helping our environment by creating less waste.

Flags Across theNation, is one organization that has taken our waste and worked to recycle them into timeless pieces of art done by members of the community. We donated 1,000 black closed cell sponges to Flags Across the Nation. These sponges were used in their ART for Veterans class.

In addition to this organization we have donated our cork centers and gasket cores to local art teachers & crafters who have used these pieces in their art and craft creations. They’ve been used for things like bulletin boards, Christmas ornaments and key chains, just to name a few.

Let us know which pieces of art are your favorite and if you have any other suggestions for what we can do with our leftover materials.

The Natural Progression of Rubber Molding

Rubber is by no means a new substance, dating back to 1500 B.C., although it is one that has evolved significantly in the last 140 years. This evolution has come from chemical alterations being applied to natural rubber in its molten state, creating specialized versions known as synthetic rubbers. How rubber is formed and manufactured is a parallel evolution, as more efficient and detail oriented techniques, such as rubber molding, are now equally as popular as the rubber extrusion techniques that have been around longer. Technological advancements are changing the face of our world in wonderful ways, including the natural progression occurring with materials such as synthetic rubber and the processes that turn it into useful products, such as rubber molding. However, this evolution does not mean that the older die casting methods and the original substances like natural rubber are forgotten. In this case progression does not wipe out the competition; it only dominates it.

Beginning with the basics, natural rubber is a substance developed from latex, which is a milky substance extracted from a few flowering plants. The most notable source is the Pará rubber tree, although other latex producers include the rubber fig and the Panama rubber tree. Much like the process for collecting maple sugar, a rubber source has a hole drilled into it and a container attached to the tree to collect the latex as it leaks out, which is known as “tapping”. Before natural rubber can be used to create the abundance of rubber products on the market today, it must be treated so that when it is shaped it will hold that shape.

This is partly why the production of synthetic rubber was so obvious in the progression of the material, because it already required additional substances to be useable. The inherent characteristics of rubber include strength, excellent elasticity and a water-proof surface. When synthetic rubbers were produced, such as neoprene, EPDMand silicone rubber, additional characteristics such as heat resistance, chemical inertness, corrosion resistance and adjustable rigidity and flexibility were added to the list. This evolution of rubber has benefited the industrial world as well as everyday consumers without wiping out the natural rubber sources, which are still utilized although not to the same degree.

Rubber molding therefore deals with synthetic rubber substances more than it does with natural rubber, just as most industrial manufacturing companies that use rubber utilize molding methods a bit more often then rubber extrusion. The technique rubber extrusion uses involves a screw extruding machine, which presses molten rubber through a specially cast die. The rubber comes out the other end in an identical shape to that of the die it passed through. This is a quick and effective process, although it cannot be used to create the same complex, multidimensional geometries that molding can. However, rubber extrusion is still a viable process utilized often to make items such as weather-stripping, trim, grommets, bumpers and seals, all of which are used for climate and moisture control in specific environments. It is also the platform from which rubber molding launched their more precision focused methods.

The variety of rubber molding techniques have rejuvenated the way industrial manufacturing is able to produce rubber products, and it has increased the possibilities when trying to create exactly what is necessary for a specific application. For example, the rubber seals used in high-pressure environments such as the construction of a space shuttle need to be developed and designed to fit perfectly where they are needed. Processes like injection molding, compression molding and transfer molding, which all involve closed dies where molten rubber is injected so that every nook and cranny of the mold is filled with the rubber substance for an exact replica, meet that need for perfection. The evolution of one process into another has enabled us to create items that make products safer and more perfect, which in some cases is just aesthetically pleasing and in other cases is the difference between life and death. Progression is what we as a human race have embraced since we began living on this earth, and something we should never stop doing, regardless of the arena in which we are doing it. Rubber molding and synthetic rubber are just two of many examples in the evolution of human technology and human experience.

Rubber Bushings for Safety

Production and manufacturing industries use heavy machinery as a common occurrence. The results of this can be loud and dangerous workplaces. When you have heavy pieces working at once and have them vibrating and moving with numerous small parts, it is important to take the necessary safety precautions. One item that is often considered is the addition of rubber bushings.

Commonly, rubber bushings are forms of extruded rubber that are used to reduce or isolate vibration in machinery. Each piece of machinery is unique and has different qualifications for parts, sizing, and other items. Rubber bushings are able to take any shape. Bushings can be designed for ways to absorb, reduce, and/or isolate vibration in a machine or set of machinery. While they are available in any shape and can even be custom created, their most common form tends to be shaped as cylinders. Typically, they are fitted with metal tubes that can assist in increasing the bushings strength.

These products are useful for softening noise and vibration in heavy machinery and these products can be useful in suspension systems as well. They are seen in cars and skateboard truck systems. Not only do they help in this way, but they are also able to extend the life of the metal parts that they are being used with. The systems provide a buffer between metal components. This makes them smoother for movement. The thing to keep in mind is that because of intense situations which the systems are applied to, they will wear down. These bushings should be checked regularly to see if they need maintenance or replacement.
