Rubber Compression Molding Services
Compression molding is a manufacturing process by which rubber is melted into a mold cavity. Plugs are then placed in the top of the cavity to heat and pressurize the rubber, where it is cured and formed into a unique product or component. Compression molding is a cost-effective method for manufacturing large parts.Ace Seal is an ISO/TS certified provider of custom compression molding services for a wide range of rubber materials. With over 35 years of experience, we are an expert manufacturer of custom molded products. Our advanced technologies allow us to deliver high-quality rubber components that can be used in a variety of industry applications.

Advantages of Compression Molding
This process offers several benefits, including:
- Fast turnaround times
- Least expensive production option
- Little to no tooling required
- Suitable for large parts & components
- Enhanced strength and durability
- Low waste
Compression molding is best suited for parts that do not require tight tolerances or have complex configurations. Parts molded using this method also require deflashing, which can sometimes extend production time. Our experts can help you decide whether rubber compression molding is the right choice for your project.
Choosing the Right Material for Your Custom Compression Mold
Each industry has its own set of regulations, so it’s important to consider your application requirements before selecting the appropriate rubber material for your project. What works for automotive components may not work for medical devices. Common considerations include:
- Weather and environment (indoor vs outdoor)
- Temperature tolerance
- Exposure to potentially corrosive substances (chemicals, oils, gases, fuels, etc.)
- Production costs
- Industry regulations and requirements
Ace Seal works with a wide selection of rubber materials. Browse just some of the options available to you below. If you are unsure which material is best suited to your project needs, reach out to a member of our staff, and we will assist you.
Rubber Material Options
Buna-N (Nitrile) Compression Molding
Buna-N, also known as nitrile, is a synthetic rubber commonly used in the aerospace industry due to its resistance to oil, fuel, and various acids and alkalines. Its hypoallergenic properties also make it a popular choice for medical and dental applications.
EPDM Compression Molding
Ethylene-Propylene-Diene-Methylene, or EPDM, is one of the most versatile rubbers available due to its resistance to heat, weather, and harmful UV. EPDM also provides excellent abrasion resistance, making it especially suitable for industrial or automotive applications.
Fluorosilicone Compression Molding
Also known as FVMQ, flurosilicone is a saturated rubber material that provides strong stability in high and low temperatures. It is often used as a sealant due to its resistance to a variety of oils, fuels, and solvents.
Neoprene Compression Molding
Neoprene maintains stability and flexibility under extreme weather and temperature conditions. This material is resistant to chemicals, fluids, and combustion, which makes it ideal for a variety of demanding sealing applications.
Silicone Compression Molding
Silicone rubber is generally non-reactive, stable, and resistant to extreme environments. This material can withstand temperatures as low as -75°F and as high as 450°F, making it ideal for a wide host of applications, including automotive manufacturing, medical devices, food storage, electronics, and more.
Viton® Compression Molding
Known for its high density, Viton® is a synthetic rubber well suited to ultra-harsh environments. This material comes in a variety of grades that are all resistant to high temperatures, petroleum products, solvents, and a wide range of chemicals.
