Thermo-Compression Molding of a Non-Woven Polyester Acoustic Duct for the Automotive Industry
At 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.

Compression Molding of a Non-Woven Porous HVAC Duct for the Automotive Industry
S&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.
