Suggestions That Can Help With Transfer Molding In Rubber Parts Manufacturing

Posted on: 20 October 2021


When you put rubber compounds in a closed mold as to create a certain part, this process is known a transfer molding. It's used a lot by custom rubber part manufacturers. If you want to have complete success with it, here are some suggestions worth looking over.

Make Sure Molds are Strategically Manufactured

In order to create rubber parts through transfer molding, you need molds. However, you need to make sure they're strategically designed and manufactured in order to give you high-quality parts that can be made as quickly as possible.

The mold you use needs to provide a couple of things, in particular, such as a consistent temperature range and a fill that's properly balanced. These elements can help you get quality parts that have the same characteristics and dimensions, even if you have a long production run to complete for larger orders from a client.

Consider Steam Heating Methods

As mentioned earlier, transfer molding is only going to work if you're able to achieve the right temperature range that's uniform all over the mold. Then you won't have to worry as much about problems like warping and other defects.

One of the best heating methods that can deliver uniform results is steam. Using a system that produces hot steam will make it easy to achieve uniform heating all along with the mold that you've designed to make a specific rubber part. 

Select the Appropriate Subfield 

Within the main category of transfer molding in rubber parts manufacturing, there are different subfields. If you want to get the best results and know exactly how your rubber parts will turn out after this molding process, make sure you know which subfield to go with.

For instance, if you're trying to make really smart rubber parts, then micro-transfer molding is the best option. It can be used to make substantially small parts, but do so in a way that keeps defects and structural issues at bay. Whereas if you are looking to embed objects in the custom rubber part being manufactured, then resin transfer molding might be best for your project.

There are a lot of molding options for rubber materials, with transfer molding being more predictable since it is done using closed molds. If you take the time to see how this molding process works and how it should be set up, you can make decisions that guide your rubber part projects correctly.
