Preparation tool: You need to prepare a tape measure or ruler for measurement.
Determine measurement position: Determine the position of the convex edge you want to measure, usually at the edge of the lid.
Align the tape measure or ruler with the raised edge: Align the starting point of the tape measure or ruler with the starting point of the raised edge, ensuring that it fits vertically with the raised edge.
Measure length: Gently slide the tape measure or ruler along the curve of the convex edge until the endpoint position of the convex edge is measured.
Record measurement results: Record the length of the protrusion you measured.
Through the above steps, you can accurately measure the length of the convex edge of the aluminum-plastic composite cover. Please ensure accuracy and precision during measurement.
