Three Methods Of Rubber Molding Production

Custom rubber molding products find application across a wide range of industries. In fact, it is difficult to imagine an industry or manufacturing setting that can work without rubber. Industries employ rubber items in different capacities to meet their production demands or aid in the production process. For instance, automobile industry relies on customised rubber products or components for the production of new vehicles. Tyres, tubes and various other rubber components find place in the vehicle production. These components are produced by various methods of Custom Rubber Moulding To Customer Specification. The method of rubber production also decides the cost of the rubber. Let’s have a look at three rubber production methods that are most commonly used:

Transfer molding

It is a method in which an uncured slug of rubber is placed in a chamber above the customised cavity of mold. Pressure is applied directly to this chamber in order to force the rubber to pass through small opening which are called as sprues. The rubber then transfers through those openings and fill the mold cavity. The rubber is left in the mold until it is fully cured.

Transfer molding ensures faster curing time than other methods because extensive amount of heat is produced during the process. Also, it results in less wastage because the material remains inside a closed chamber throughout the process. This method can produce highly complex designs but cost a little more.

Compression molding

This is the oldest and the simplest method of producing Rubber Molding Products. During this process, an uncured slug of rubber is seated in a cavity between two plates which are later pressed together. The shape of the cavity is designed according to the desired form of the final product. Pressure is applied to the plates in order to make rubber conform to the shape of the cavity. Mold is kept closed until the product is cured.

This is a simple and economical method, but requires more time and effort to do the entire process. The process is manual so chances of inconsistency may persist.

Injection molding

Injection molding is the most expensive and sophisticated method of rubber molding. However, the method always results in the most precise and consistent results. In this method, the uncured rubber is softened before molding and then injected into the mold in order to make desired products. The process is fully automated and requires a precise amount of raw material. The cavity of the mold remains closed throughout the process thereby wastage is not a problem. But yes, this is a complicated and expensive option.
