Rubber Transfer Molding
Custom rubber transfer molding can be seen as a combination of compression and injection molding and is great for high-quantity rubber molding needs. This process also allows for metal inserts and other custom options to meet specific needs. In addition to compression and injection molding, transfer molding is a great option to have when considering your manufacturing options.
