Rubber Compression Molding: Science Meets Productivity

When talking to experts, most agree that rubber compression molding is both a science and an art. After all, this process involves using rubber material, which, depending on the type, produces different products. For a successful rubber molding process, a top manufacturer knows what to use, how to use it, and what to look for to ensure you receive a superior finished product.


Because both science and art play a crucial role in making compressed rubber products, it is imperative that you hire the right manufacturing company. Otherwise, you could end up with a subpar product, which could damage relationships with your customers and tarnish your good reputation. To better understand how the rubber molding process works, consider the following.


The Molding Process

Depending on the compressed molded products that you need, a reputable manufacturer will select the appropriate uncured rubber material. To control weight and shape, the operator uses a preform. After getting placed into the mold cavity, the cover closes, and the material is compressed between two plates. That compression is what forces the material compound to flow and fill the inside area of the mold cavity.


Until the appropriate amount of pressure and the correct temperature is reached, the rubber material remains compressed, allowing for the cure system to activate. Overseeing the process of compressing molding products is an experienced and trained operator. That individual is responsible for determining the right curing cycle time for optimal processing. With the cycle time complete, the now-molded part or component ejects from the mold cavity.


Advantages of Compressing Molding Products

When looking at this process compared to others, it offers several advantages. As an example, tooling is not as sophisticated in most cases. Because of that, manufacturing parts and components is easier and more affordable. Also, there is not as much wasted material using the compressed rubber molding process, which again, saves you money.


Avoiding Defects

From both a scientific and an artistic perspective, a professional operator who uses a cutting-edge machine and superior quality rubber can quickly identify potential problems. As a result, there is less risk of extended manufacturing time, which would delay your order and possibly impact you negatively in other ways as well. Whether it’s blistering, porosity, or some other defect, issues get identified and corrected immediately.
