Rubber Engine Mounts Molding Process

Rubber Engine Mounts Molding Process

There are three different molding processes for rubber engine mounts. Each one is used for specific purposes, so it’s important to consider your production needs. Here are the three processes:

Injection molding: this is one of the most common molding processes. It utilizes an injector to push the polymer into the mold. Once it is cured, the mold will be removed. Injection rubber molding is best for complex parts that need to be made at high production volumes. 

Transfer molding: this is one of the least commonly used molding processes. Transfer molding starts with a solid rubber charge which is heated. Once heated, the liquid rubber will enter into the mold and cure. Transfer molding is a great option for complex parts that must be produced at a low volume. 

Compression molding: this method of molding utilizes a charge placed into a mold which is then compressed and heated. Once cured the part is removed from the mold. This type of molding is typically used for less complex, low volume parts.

Choosing a molding process will greatly depend on the complexity of the part and how many parts are needed.
