Injection molding is a manufacturing process by which rubber or plastic is injected into a custom mold to produce intricate shapes designed to meet unique specifications. This method is ideal when manufacturing runs of identical parts that would be difficult to replicate through other manufacturing techniques. Injection molding offers several benefits, including:

  • Fast production times
  • Cost-effective
  • Consistent quality
  • Enhanced strength and durability
  • Little to no finishing required
  • Low waste

Ace Seal is an ISO/TS certified provider of custom injection molding services for a variety of plastic and rubber materials. With over 35 years of experience, we are an expert manufacturer of custom molded products. Our advanced technologies allow us to work with tight tolerances to deliver high-quality simple and complex molded parts to our consumers.

Choosing the Right Material for Your Custom Injection Mold

Each industry has its own set of regulations, so it’s important to consider your application requirements before selecting the appropriate 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 and plastic 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 & Plastic Material Options

Nylon Injection Molding

Nylon 6 and nylon 66 provide high tensile strength and elasticity. Resistant to harsh chemicals, these materials are used for applications that require high mechanical strength, such as automotive components and machine parts.

HDPE Injection Molding

High density polyethylene provides a high strength-to-weight density ratio and is resistant to a variety of solvents. It is commonly used for items like plastic bottles, food storage containers, outdoor furniture, and piping.

PVC Injection Molding

Polyvinyl chloride, or PVC, is one of the most widely used synthetic polymers. It’s lightweight, high strength, and low cost make it a popular choice amongst almost any industry application.

Polypropylene Injection Molding

Polypropylene is a thermoplastic polymer that is durable and chemical resistant. It contains insulative properties, making it ideal for applications that generate heat, such as electronic components.

Polycarbonate Injection Molding

Polycarbonate is a strong material that can withstand significant impact. Naturally transparent, this plastic is commonly used to make windows, lighting fixtures, eyeglasses, medical devices, and automotive components.

ABS Injection Molding

Acrylonitrile butadiene styrene, or ABS, has a low melting point and very high tensile strength. This plastic is one of the most commonly used materials for 3D manufacturing and the fabrication of OEM parts.

Polyurethane Injection Molding

Polyurethane provides excellent elasticity and is resistant to chemicals and abrasion. This material can survive high impact and harsh environments, making it useful for automotive and hydraulic applications.

Buna-N (Nitrile) Injection 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.

Silicone Injection 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.

Neoprene Injection Molding

Neoprene maintains excellent stability under extreme weather and temperature conditions. This material is frequently used for demanding sealing applications due to its resistance to harsh chemicals, fluids, and gases.
