Abstract: The influence of elastic micro-deformation of cavity on the precision of product was analyzed. A new approach to cavity design was proposed for the controlling of product precision. In order to realize precision molding, it was necessary to strictly control the value and fluctuation of the hold pressure.

Key words: precision molding, high pressure molding, product precision, hold pressure
