Rubber burrs which are formed on a first molding product are set to the closer side of spaces of side surfaces. Therefore, when the first molding product is placed in a resin mold for a resin molding process, it is unnecessary to insert a rubber-burr portion in the resin mold at a predetermined position (at which protrusion rubber parts can be brought into tight contact with the resin mold for sealing). That is, the rubber burrs formed along the parting lines can be placed in a cavity of the resin mold. Therefore, since second rubber covering parts can be easily inserted in the resin mold at the predetermined positions and working time can be reduced, workability can be improved. Moreover, since the predetermined positions of the resin mold can be surely sealed by tight contact with the side faces, generation of resin burrs can be suppressed.

The composite material includes at least 20 vol % of the particles for a polydispersity index PI of the particle size distribution of <0.7 or are present in at least 30 vol % of the composite material for the polydispersity index in a range from 0.7 to <1.2, or are present in at least 40 vol % of the composite material for the polydispersity index of >1.2.

The invention relates to a rectangle detection and extraction method based on contour matching optimization, which is characterized in that it comprises the following steps: Step 1: Detect and extract the edge contour of the original image to obtain the edge image; Step 2: Calculate each non-edge pixel in the edge image The distance D(p) from the nearest edge pixel, and then perform normalized distance transformation to obtain the normalized distance S(p), where p is a non-edge pixel; Step 3: use a regular grid to cover the edge image, and Assign initial values ​​to the rectangles in the regular grid; step 4: calculate the comprehensive contour matching degree of each rectangle in the regular grid and the rectangles in the rectangle's neighborhood set, and select the rectangle with the largest contour matching degree as the initial rectangle extracted; step 5: Remove repeated rectangles and non-rectangles to obtain the final extraction rectangle of the edge image. The method of the invention regards the rectangle as a whole, expresses it as a five-dimensional vector parameter, and realizes high-precision detection and extraction of the rectangle by optimizing the matching degree between the outline of the rectangle and the edge extracted from the image.
