What is Rubber Molding?
Rubber molding is a process used for creating industrial rubber parts. This process uses heat and pressure to mold rubber into specific rubber components used in many different industries. This can be done via multiple types of molding processes, including injection molding, transfer molding, and compression molding. PHB specializes in injection molding services, as well as insert molding and overmolding.
Rubber molding has a wide range of uses, and is frequently used to make gaskets, tubing, hoses, and many other industrial parts. Both synthetic and natural rubber can be used, and the decision of which to go with is often based on the specific application of the part.
Types of Rubber Used in Rubber Molding
There are many different types of rubber, both synthetic and natural. Each has its own unique properties which may make it a better choice for a specific application. PHB utilizes the following rubbers for its rubber injection molding:
- Viton: Viton has a strong heat resistance, so it’s an ideal material for applications that will experience high temperatures of up to 400° F.
- Nitrile: Nitrile is ideal for applications where it will be exposed to oil, fuel, and grease.
- Neoprene: Neoprene is a great all-around rubber with many applications, and is particularly useful in outdoor applications due to its strong resistance to ozone, sunlight, oxidation, and water.
- Hycar: Hycar has strong physical properties, including good heat resistance, but its strongest property is its resistance to water and fuels.
- Silicones: Silicone is one of the purest and most durable forms of rubber, which allows for its use in food, medical, and pharmaceutical applications.
- NR:Natural rubber has strong all around physical properties, with good resistance to ozone, sunlight, oils, petroleum, oxidation, and water.
- EPDM: EPDM is commonly used for outdoor applications, most famously for roofing. This is due to its strong resistance to ozone, extreme temperatures, and UV.
- Custom Blends: Depending on the application, creating a custom blend to maximize the necessary properties may be your best option. Get in touch with us to learn more about making a custom blend for your application.
Advantages & Disadvantages of Rubber Molding
Rubber molded products have many advantages. First, this process allows for customization, both in regards to materials used – PHB offers many different types of rubber with different properties – as well as the ability to mold that rubber into the exact shape needed for a part. Rubber itself is also a great material to use for many applications due to its strong physical and chemical properties, including water resistance, durability, and ability to maintain its shape.
There are also many advantages to using injection molding to make rubber parts. This includes short cycle times, which allows for mass production of parts in a short amount of time. Injection molding is also flexible, and overall is an efficient and cost effective process for mass production.
The main disadvantage of using injection molding for rubber is its initial tooling cost. The initial setup and machinery are costly, which is why this process is most cost effective when producing high quantities of rubber parts.
