Let’s dive in — see how high-precision injection moulds for automotive air vent housings are built and run. In this walkthrough, we show the mould design, parting line and ejection setup, cooling layout, and trial moulding of PC+ABS/PP parts. Watch how tight tolerances, smooth surface finish, and stable cycle times are achieved for OEM and Tier 1 interior programs, including LHD/RHD and multi-zone vent variants.
