Adjust the slump of the concrete, the frequency of the vibration and talk to someone like Armcon or Numold about the use of moulding additives.

could be a few things not enough water in mix like my mix to look like porrige
what releasing oil you using and how much you are putting on moulds
where are the air holes mainly in the corners or on the main face of the slab
try diffrent things does your molds dance on your table or just sit
if they dance you wont get a good vibe so alter your motor or put rubber or wood under you moulds
