Custom Rubber Parts

At Aero Rubber, we provide rubber molding services, rubber part fabrication, and rubber extrusion services.

Rubber Molding

Rubber molding processes form uncured rubber and other elastomers into useable products. At Aero Rubber, we offer the following rubber molding methods:

• Compression Molding. This process relies on compressive force to enclose a rubber preform into the mold cavity. The rubber material heats up and cures within the mold, allowing it to retain its form even after it is removed from the mold. This method offers low tool costs, fast lead times, and many other benefits.
• Rubber Injection Molding. Rubber material is heated until it is plasticized before being injected at high pressures into a mold cavity. The rubber material is then subjected to high pressure and heat, which starts the vulcanization process. Rubber injection molding is the preferred option for complex designs due to its high level of precision and consistency.
• Liquid Silicone Rubber (LSR) Injection Molding. This method is similar to injection molding but uses two materials: a base-forming compound and a catalyst. These components are combined within the mold before being heated and pressurized as normal. Benefits of LSR injection molding include biocompatibility, temperature and chemical resistance, and durability.

Fabricated Rubber Parts

Our team of manufacturing and fabrication experts can create a wide range of products and components from rubber sheets, tubes, cords, and blanks based on customer specifications. Some of the fabrication methods we specialize in include:

• Die Cutting. We use computer-controlled die cutting systems to provide fast and accurate die cutting services. We can die cut simple and intricate parts, seals, and gaskets from a wide range of rubber materials with quick turnaround times. Die cutting is ideal for both short and long production runs.
• Lathe Cutting. Lathe cutting provides parts with higher tolerances and superior sealing performance compared to die cutting. We work with a range of rubber elastomers and can produce almost any ID/OD dimensional combination. This method is ideal for high-volume production.
• Slitting. Slitting is a popular process for creating extremely precise, consistent strips of material from a rubber substrate. At Aero Rubber, we can slit long lengths and custom widths. We can also include pressure-sensitive adhesives when needed.
• Splicing. Splicing processes rejoin cut rubber strips to create a new shape. For example, strips of seals can be joined at the edges to form a circle, rectangle, or other shape. Our splicing processes include cold bond splicing and vulcanized bonding, and we can handle nearly any splice geometry.
• Water Jet Cutting. This process uses a high-pressure stream of water to cut through rubber materials. This method offers high levels of precision and speed compared to other cutting techniques. It also features lowers costs and the ability to cut dense and sponge materials.

Rubber Extrusion

In rubber extrusion processes, rubber material is forced through a die to create a continuous shape with a uniform cross-sectional area. Extruded rubber products are commonly used for door seals, bumpers, windows, and more. At Aero Rubber, we can accommodate a wide range of profile shapes and work with an array of elastomer materials to create rubber extrusions that meet customer specifications.

You’ll Need to Know or Discuss the Following:

1. The temperature range that your part will be operating in;
2. The environment your product will be working in, including any chemicals, gases, or light sources it will be exposed to;
3. Material specifications your parts must meet

Once your Aero Sales Engineer knows the basic operating conditions your part will require, they’ll be able to offer you options so you can choose what will work best for your application.

Major Items for Discussion When Purchasing Custom Rubber Products:

• Characteristics/dimensions that are critical to you
• Tolerances to be held for specified dimensions
• Which characteristics/dimensions are “for reference purposes only”
• Standards that apply and the applicable revision level of each
• What/whose drawing/print the order is to be manufactured to
• What/whose drawing/print the finished product must comply with
• If a sample for approval is required prior to production
• Whether Certification of Conformance is required
• If laboratory testing for specific material properties is required
• The date you require shipment by
