Aluminum Frame Profile With Window Casement and Machined Mounting Holes

We operate dedicated lines that support clean seating and repeatable mounting for window casements. We make critical dimensions, datum structures, and finish requirements the primary controls during machining and inspection. From a dimensioned print, we control mounting hole patterns and reference faces before cutting. We perform the frame machining in Shanghai at an ISO 9001 and ISO 14001–registered facility. Pricing and production timing are set by frame length range, machining complexity, and finish requirements. Window casement alignment is held consistently so mounting holes, sealing edges, and surrounding frame geometry stay in step from trial runs to repeat orders.
