At Philpott Solutions Group, we can manufacture high-quality rubber parts for any application. Our robust molding capabilities include rubber transfer molding, rubber compression molding and rubber injection molding – giving us the ability to mold complex parts into any shape specified. So, what’s the difference between these molding processes? Let’s take a look!
Rubber Transfer Molding
Rubber transfer molding allows us to produce highly complex designs for a myriad of applications. In fact, from bowling lane bumpers to rubber pads for automotive, truck, OEM and many other applications, the transfer molded products we manufacture for our customers are everywhere you look. Unlike compression molding where the rubber material is heated and the part is formed between upper and lower dies, the rubber transfer molding process involves the use of a ram to compress the rubber material into a transfer mold where it is heated and compressed further into a mold cavity. After the rubber part cures, it is removed from the mold cavity and ready for the customer.
Rubber Compression Molding
Similar to rubber transfer molding, compression molding allows us to manufacture complex shapes and designs for numerous applications. A key difference between the two processes is that compression molding does not require a transfer mold. While the two molding processing use different machines, both serve a similar purpose. However, compression molding cannot produce parts with intricate shapes like rubber transfer molding and rubber injection molding can.
Rubber Injection Molding
If your parts need to be precise shapes, then you need rubber injection molding. This process is similar to transfer molding, but the rubber charge material is continuously supplied through a nozzle that injects the heated and liquefied rubber into a mold cavity where it is compressed and cured. As a contract manufacturer, we have the capability to injection mold parts for any application. From small volumes to millions of parts, we’re able to take your mold, or one that we custom design and engineer for you, and fabricate parts that meet your exact specifications.
