Abstract
Manufacture to make the upper end(114) and lower end(116) of the die the same. Give the work part of the die some taper(15). The tapering angle is 0.2-0.6 depending upon the thickness of the molded object. Keep the amount of the width increase of it within 0.01-0.02mm. By doing so, the size increase of the object which takes place immediately after it passes thru the tapering position(15) by the force of the spring back phenomenon, can be carried out smoothly, preventing the possible damage from the spring back.
