Thermoplastic Duct Housing with Rectangular Vent Housing and Integral Mounting Flanges

The duct aperture and flange mounting faces are moulded from the same tool cavity, so aperture centre position relative to the flange bolt hole pattern is fixed in the tool and will not drift between production runs the way a two-piece assembled housing would. Nantong Hongen Automotive Parts (Nantong, Jiangsu, established 2014) injection-moulds thermoplastic rectangular vent housings with integral mounting flanges at their approximately 2,500 m² Nantong facility. Duct aperture dimensions, flange flatness, and bolt hole positions are all confirmed during first-piece before production release. ISO 9001 certification governs production traceability for automotive HVAC, home appliance, power tool, and general industry vent housing applications. For quoting, include aperture dimensions, flange specification, hole pattern, and thermoplastic grade so we can prepare a moulding quotation from our Nantong team, serving medical equipment, consumer goods (others), and motorsport applications.
