Abstract
PURPOSE: To perform two-color forming with clear exposure of symbols from the outer circumferential surface of the secondary forming material by providing concave resin feed grooves extending from the primary forming material's side wall to the rear of symbols and subsequently preventing the symbol's surface being covered by the secondary forming material.
CONSTITUTION: Ring-shaped primarily formed element 2 with plural symbols 1 provided in a projected form along the outer circumferential surface is attached inside the cavity of the secondary forming mold 4. Then the surface of symbols 1 are brought into contact with side wall 6 and molten secondary forming material dyed in different color from the primary forming material, is injected into metal mold 4. The secondary forming material is charged into the circumference of symbols 1 through resin feed groove 3. At that time, the primarily formed element 2 is pressed against side wall 6 by the pressure caused by the secondary forming material being fed into the cavity 5, so that the front surface of symbols 1 is not covered by the secondary forming material.
