PURPOSE:To detect the characteristics of sealing resin easily by measuring the degree of abrasion of a test-piece arranged where it contacts a flow passage according to the kind of sealing resin flowing through the flow passage. CONSTITUTION:A lower mold 10 is formed of wear-resistant metal, the spiral flow passage 11 is formed, and an injection part 12 for the sealing resin is formed at the center part of the flow passage 11. Bottomed holes 14 where test-pieces are supported are formed at plural positions along the flow passage 11, and leg parts 13a of the test-pieces 13 are inserted into the holes 14, so that the outer circumferences of the heads 15 of the test-pieces 13 contact the flow passage 11. |
