Compression Molding Of A Non-Woven Porous HVAC Duct

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.
