a) the formation: Bavia is formed on the surface of the mold or compost in place of the exhaust system. Bavia is a consequence of the closing of the mold is not sealed, or due to pressure, mold clamping force problem. b) causes -Die manufacturing is incorrect, the error between the two halves of the mold is too large or the mold is broken. Mold clamping-force too low. -Flow temperature, cylinder temperature, speed or pressure in the injection mold is too high. -Mold close not sealed due to: mold, is joint yet mounted channels (due to dirt, corrosion). c) how to fix -Adjust the mold for the appropriate or correct the damaged spot. -Clamping force higher mold reset or change the larger machines. -Reduction of injection pressure high injection speed or pressure, keeping the smaller. -Reduce the flow temperature and mold temperature. -Check the correct surface of the closed mold, if needed for the imagery.-Choose the appropriate port location.
