Rectangular Housing Shell with Plastic Equipment Housing and Triangular Flange Multiple Holes

Measuring and control instrument enclosures, elevator control unit housings, and energy storage module covers use a plastic equipment housing where triangular flange hole position and wall flatness together determine whether the cover bolts flush to its mating chassis and whether the snap latch slot engages at the correct closing force; flange hole position error forces bolts off their thread axis, while wall flatness deviation leaves a visible gap at the parting line. Shanghai Hanshen (Shanghai, founded 1991) CNC-mills this thermoplastic plastic equipment housing with rectangular shell, triangular flange, and multiple holes with CNC milling and boring and milling machining at their north of 35,000 m² Shanghai facility, with flange hole positions, snap latch geometry, and wall flatness confirmed against your released print during in-process inspection. ISO 9001 certification governs process documentation for elevator, energy storage, measuring and control, and OEM manufacturing plastic equipment housing applications. We can quote once we have flange dimensions, hole positions, snap geometry, and thermoplastic grade from your drawing.
