METHOD AND APPARATUS FOR JUDGING PLASTIC PROPERTIES OF INJECTION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus capable of properly judging the plastic properties of a plastic injection material. SOLUTION: The apparatus for judging the plastic properties of the plastic injection material is constituted of a truncated cone-shaped fall cone, a fall cone holder for freely holding and dropping the fall cone on the surface of the injection material and a display device for displaying the value of the plastic properties of the injection material on the basis of the penetration quantity of the fall cone to the injection material to judge the plastic properties of the injection material on the basis of the penetration quantity of the fall cone to the injection material.
