WARCO specializes in custom rubber extrusions, from one-time special orders to high-volume runs. Our extruders can produce custom rubber profiles in a wide variety of sizes and shapes including cable jacketing, O-ring cord, tubing, rubber seals, squares, and rectangles. Our experienced sales team can provide product selection and design support, whether you require standard extruded rubber gaskets or custom extruded rubber profiles. With our in-house formulation and mixing capabilities coupled with die design and fabrication on state-of-the-art die-making equipment, we can design a rubber compound to meet your specific requirements for quality and performance while minimizing cost.

Our Extrusion Manufacturing Process
The process begins with our experienced sales representatives assisting you in product development, design and profile construction. Once the product’s needs, applications, and timeline has been determined, the request is sent to our Research & Development Lab. In our Research and Development Lab, our team of chemists and engineers will create a custom formulation that will best fit the determined requirements. Our commitment to research and formulation development has kept us at the leading edge of rubber technological innovation. This formulation is then sent to our In House Mixing undergoes the first Quality Assurance Check.
All formulas are mixed with our Banbury® machine and thoroughly tested before it is used in manufacturing in order to make sure that we are delivering excellence in quality. After the rubber compound batch has been formulated, mixed, and tested, it is now able to move to our compound and mix stock room to begin the manufacturing process.
Next, the material is taken to our extrusion department. We offer a multitude of different options when it comes to extrusions including microwave, cold feed with hot air vulcanization, and much more! 
We have three ways to vulcanize our extruded profiles, Autoclave, Hot Air Convection and Microwave. If the extrusion requires separate vulcanization, then our team prepares the material in a way that it will maintain its shape and quality throughout the process.
Once the extrusion is cured then it will be subject to a number of different product preparation methods as needed. We offer a number of different services in order to ensure that our customers get the highest quality product available. These services include marking, stenciling, private branding and much more. If needed your extrusion can be spliced with our splicing department, learn more about splicing below.
At this time, our packaging and shipping department prepares the rubber for transport. Each of our products are packed with extreme care and precision in order to ensure that your product is delivered to you in pristine condition. These products are given to our partners within the transportation industry and they deliver directly to wherever your desire.
Compounding capabilities include Neoprene, EPDM, Nitrile, Fluorozone® FKM & Genuine Viton®, Natural Rubber and Silicone. We also provide custom compounding to meet Military, AMS, SAE, ASTM, NSF, FDA and commercial specifications. View our Specifications.
WARCO’s diverse production equipment & capabilities include:

- A 50 FT autoclave produces straight lengths up to 50 FT
- A unique pole cure system that enables us to produce rubber tubing with near-perfect inside diameters
- Vulcanized spliced and rubber extrusions
- Mil-Spec and custom markings
Pristine Material Handling. Profiles for conveyor systems and warehouse applications. Compounds can be formulated to meet industrial, as well as food grade applications -“From rocks to eggs!”
Our extrusion equipment is extremely versatile.
As the industry-leading specialists in rubber extrusions, we are capable of producing cable jacketing, O-ring cord stock, tubing, squares, rectangles, as well as irregular shapes in a wide variety of sizes. Rectangles can be up to 5 inches thick and 6 inches wide or 1 1/2 IN thick and 12 IN wide with cord diameters up to 7 IN. Request a custom job
Rubber extrusions can be spliced and vulcanized to form an endless variety of shapes. WARCO’s extensive splicing capabilities allow us to produce seals and gaskets for a broad array of aerospace, automotive, chemical processing, construction, food processing, industrial, oil and gas, wire and cable, as well as military applications.
Our Splicing Department personnel are experts in creating high-quality spliced products. Our spliced parts are hot vulcanized, creating a stronger bond than can be achieved with standard adhesives. WARCO formulates and mixes its own proprietary splice compounds for the specific rubber parts that we’re splicing. After the application of the splice compound, the parts are then placed in molds where heat and pressure are applied to hot vulcanize the material, ensuring a long-lasting, reliable product.
Advanced equipment and multiple cavity molds permit high-volume production of O-ring and various other shapes – including squares, rectangles, and irregular profiles – at a fraction of the cost of alternative production methods. Combinations of extruded and molded parts can be spliced as well, allowing limitless configurations; resulting in substantial savings in time and tooling costs of fully molded products.
WARCO has been the source of a number of different custom formulations (over 4,000) and a variety of unique and diverse products. Our legacy of over 110 years in rubber manufacturing has allowed us to become true experts in extrusion & splice rubber manufacturing. Even if you do not know how our rubber can fulfill your application, our team has been trained to assist you and determine how our products can solve your problem.
