As part of our full range of services, Cascade Gasket provides rubber and elastomer certified testing services for rubber and elastomer products for the aerospace, bus, communication, maritime, and train industries. We offer physical, thermal, and chemical testing services, including hardness, tensile strength, elongation, adhesion, modulus, and compression set testing. In addition, we can test for tear resistance and abrasion resistance, resilience, and flexibility. Our success in developing superb testing and production practices has earned us AS-9100 and AS-9102 aerospace certifications, as well as ISO 9001:2008 certification. We can also assist with consulting, design, research and development, and prototyping needs in concurrence with, or in addition to our testing services. Contact Cascade Gasket with any product drawings or information to begin the testing process.

Cascade Gasket assisted in the design and then manufactured this flight critical exit door seal for a commercial aircraft. The seal effectively blocks both air and water from the aircrafts interior, in flight and while grounded, and is composed of three materials: BMS 1-57 silicone rubber, D2000 inter-weave fabric, and inconel metal inserts at the top of the seal. Although rubber compression molding was the primary manufacturing process, several steps were involved in creating the door seal. First, the inconel metal inserts were pre-fabricated and coated, in preparation for receiving the rubber and fabric. Next, the part was hand formed and laid in the mold in four separate sections, blending together only at areas indicated by the print design. The mold was then placed under extreme heat and pressure for 4 hours, allowing the rubber to flow and fill the mold, assuming the shape of the final component, with a final tolerance of +- 0- .030. After the molding was complete, the part was cleaned and placed in an oven for 3 hours at 350 degrees Fahrenheit, to set the shape and cure the rubber. The final process involved the addition of a secondary seal, applied on the header section of the seal, for extended sealing and management of the product. The final exit door seal is both air and water tight, and measures 48 long by 27 wide.

This featured compression molded rubber seal was made using a grey rubber (BMS 1-57) compound and a corolon fabric. Because the fabric has a denser weave, it serves to increase durability. The rubber and corolon were first hand formed in the mold, then placed in the press at 230 degrees Fahrenheit (F) for 10 to 15 minutes to assume the proper shape and continuity. After the newly formed seal was removed from the mold and cleaned, it was set to post cure at 300 degrees F. During curing, the foam inserts and end plug (BMS 1-68) were formed by curing the liquid into pre-designed molds, and applying pressure and low-heat until complete. After curing, the seals holes and overall length were cut, and then it was assembled with the foam inserts and end plug, which serve to increase the products lifespan, fit, and performance. The completed seal assembly was designed to be applied in several places on a commercial aircraft, where it was mounted to metal bulkheads, to enable the sealing of metal parts.

Cascade Gasket is equipped to assist in all process steps, so contact us with your project information.

This compression molded insulation flange seal is manufactured in a series of steps. First, a foam insert (BMS 1-68) , molded in 2 parts, is bonded together into the designated shape. Next, fabric (D2000) is blended with a red silicone compound (BMS 1-74) using a red iron oxide ingredient which renders the component heat-retardant. The silicone and fabric combination is then hand applied around the foam insert to achieve the proper level of thickness, and then placed in a cool mold. A total of 6 different rubber coated fiberglass inserts are applied to the seal, at specified locations, to create the reinforced attachment points for the seal. The mold is then placed in the press at 320 degrees Fahrenheit (F) for 30 minutes, removed, cooled, and cleaned. The final component shape is set by post curing the seal at 400 degrees F. The completed insulation flange seal is used extensively in engine areas of a commercial aircraft.

Working with both metal and non-metal materials, Cascade Gasket offers full 5-axis waterjet cutting services. The full 5-axis capability combined with a 5 ft. x 10 ft. x 6 in. work envelope allow us to waterjet cut a wide range of pieces for clients in the medical, semiconductor, military, automotive, aerospace, and building industries.

Designed for use on commercial airplanes, these featured clamp blocks were value engineered to reduce significant weight of the aircraft. Made from a variety of components, including titanium screws, locking and standard washers, EPDM rubber (BMS 1-50), and carbon fiber composite channels and spacer tubes, the EPDM rubber was molded and cleaned before assembly. Each of the screws, washers, channels, and spacer tubes were purchased to adhere to strict customer specifications, and then assembled with the EPDM rubber block. As a result of the unique combination of rubber, screws, washers, channels, and spacer tubes, the clamp block assemblies were appropriate for use in almost any aircraft application, including hydraulic immersed and fuel pod locations. In addition to reducing the weight of the aircraft, the design of the assemblies reduced FOD and increased the speed and efficiency of installation.
