Common defects in BMC molding
During BMC molding, various quality defects can occur. Common issues: 1) Porosity - caused by trapped air or moisture; solution: pre-dry material, improve venting. 2) Surface blisters - caused by rapid heating; solution: optimize temperature profile. 3) Warpage - caused by uneven curing; solution: ensure uniform mold temperature. 4) Incomplete fill - caused by insufficient material or pressure; solution: increase shot size or injection pressure.
