S&A Industries Corporation

United States

Serving the transportation industries with our thermal shielding products, S&A Industries is a leading manufacturer of thermal protection sleeves that can be used to protect a variety of engine compartment and powertrain components from radiant heat sources. S&A's thermal sleeving with its high reflective and insulating features protects engine compartment and powertrain components from high temperature sources that can reach 400 Celsius. Our thermal protection sleeving, also known as reflective sleeving, is a spiral wound flexible conduit that can be produced in diameters from 8mm to 150mm, and wall thickness ranging between 1.2mm to 2.5mm. Our thermal protection sleeving can also be designed to guard against fluid penetration plus offer abrasion resistance.

S&A Industries offers a number of high-quality high performance expandable damping material options that are used for vehicle welded body damping and insulating. Common applications include floor panel silencers, tunnel, dash panel and wheel house damping. All products are custom designed and manufactured to meet our customers' specific performance requirements. Our expandable sheeting is adhered and expanded between body panels. When the body-in- white is processed through the E-Coat system the sheeting expands to provide superior sound damping and structural integrity. S&A Industries possesses the latest sheeting technology at our new Mississippi facility. We can custom blend, die cut and assemble our damping sheets to various structural vehicle body panels. We construct expandable damping sheet from asphalt based compounds. Contact S&A Industries today to learn more about our premium insulation sheeting products.

Thermo-Compression Molding of a Non-Woven Polyester Acoustic Duct for the Automotive IndustryAt S&A Industries, we're a leader in custom thermo-compression molding services. We were recently contracted by a customer in the automotive industry to fabricate a porous noise reduction duct. This duct was to be used in air induction systems on the dirty air side. This product featured an embedded hydrophobic resin, which prevents water intrusion with no negative impact to NVH. To create this custom duct, we used a non-woven material, our thermo- compression expertise, and our superior assembly services. Hydrophobic, temperature resistant polyester was used for its lighter weight than a molded plastic counterpart. The complex assembly of the duct with plastic components assembled to the air filter box interface exhibited to our customer that our experience and knowledge extends beyond thermo-compression molding and allows us to work on projects from inception to completion.

S&A Industries develops and manufactures porous duct components that help attenuate resonances in engine air induction systems, HVAC and EVHybrid Battery Cooling systems. S&A Industries can provide a single component or a complete acoustic solution system that helps to reduce noise harshness and provide a superior sound attenuating quality. Our components and porous duct systems are used by the world's leading automotive manufactures to help minimize noise propagation generated from the engine compartment. Our porous acoustic ducts are used in millions of sophisticated air induction systems, worldwide to reduce engine noise resonances. Our lightweight ducts are used to cool complex Hybrid Vehicle Batteries; our duct systems not only attenuate the blower motor noise they also protect the battery from inlet

Compression Molding of a Non-Woven Porous HVAC Duct for the Automotive IndustryS&A Industries developed this thermo-compression molded, non-woven, porous duct that reduces noise in an automotive HVAC system. The duct, which was designed to reduce the air flow imbalance between inlet and outlet openings, offered a 9 dB improvement from 1000 Hz to 16000 Hz (max blower speed at 12V) to the full blower speed. We used highly specialized software, such as LAMPSSAPY for noise, SCRYUFluent for pressure drop and UGNX for design to create and model the duct. The porous non-woven polyester used in this S&A duct is 35% lighter than a comparable, 2.5 mm-thick plastic blow-molded duct. The part improved the pressure drop by 10% at 65 cfm and met the standards for automotive interiors. Please see below or contact us directly for more information.

Compression Molding of a Non-Woven Porous Air Intake System Duct for the Automotive IndustryS&A Industries manufactured a porous, air-intake system (AIS), noise-reduction duct that meets automotive environmental and engine compartment requirements. The non-woven, compression-molded, recyclable polyester used in the duct reduces engine noise. Permeability can be adjusted to change its acoustic performance and it offers excellent temperature resistance. The porous part also weighed less than a molded plastic part and featured a water drain valve and is hydrophobic treated. The duct was created using highly specialized software, such as LAMPSSAPY for noise, SCRYUFluent for pressure drop and NX Unigraphics for design. We diligently tested and validated the parts and offered global delivery. For more information, please contact us directly.

Manufacturing of a Transmission Wire Harness Protection Sleeve for the Automotive IndustryAn automotive industry client asked S&A Industries to produce a tubular heat protection sleeve to be used on a wire harness for a high volume automotive transmission application. S&A engineers assisted in the custom-design, then developed and built the automated tooling required to cut-notch, crimp, pierce and assemble an eyelet feature for securing the sleeve to the wire harness. The S&A team also validated the thermal effectiveness of the sleeve in accordance to SAE J2302.The composite assembly featured a combination of non-woven insulating materials and highly reflective aluminum foils. The wire harness maintained a temperature of under 125C when in operation just 150 mm from the 550C heat source. Online automated inspection ensured the finished product complied with the customer-supplied specifications. For details, please see below .

Thermo-Compression Molding of a Hybrid Electric Vehicle (HEV) Duct for the Automotive IndustryCalling on our thermo-compression molding expertise for parts for the automotive industry, S&A Industries was contracted to manufacture this custom inlet and discharge duct. The compression porous duct was designed for noise reduction within a battery cooling application for hybrid vehicles. The purpose is to bring cooled air to the ESS from the cabin without creating a noise issue for the passengers. This thermo-compressed duct project allowed us to exhibit our many capabilities beyond thermo-compression including non-woven material production, hot plate welding, gluing, in line testing and complex assembly. Producing and utilizing recyclable non-woven polyester provided a 35% weight reduction compared to a plastic duct. It also afforded a temperature resistance up to 95C and breathability of 10ldm2minmbar. The duct, used globally for hybrid and electric vehicles, offered safety features to protect the expensive batteries used in the specialty vehicles. The noise performance of the part speaks for itself. The Inlet porous duct yielded 10dB improvement compared to a molded duct. The discharge porous duct yielded up to 5dB at higher frequencies.
