The groove blade of edge matching, mould coordinates under mould and groove on groove, the RPT draw rings to sequentially passing through flange mold, shaping mold forming
Finger hole depressed area groove, formed with RPT draw rings one but can be torn along groove stay piece.
Using the present invention of above-mentioned technical proposal, compared with prior art, its advantage is：
The pellet material of finger bore region can be retained by the mould, can both increase the integral face of tab body
Product, can be used to the region for retaining again, such as can be to stay printed on piece in reservation region in product packaging
LOGO, carve characters, for client provides products propaganda mode；By carrying out dent, processing line of weakness to the reservation region, hand is realized
The shaping of finger-hole, the use of draw ring is not influenceed.
Preferably, the further technical scheme of the present invention is：
The described curved knife blade arc length for cutting punch-pin accounts for the 1/3 of finger hole girth.
Described dent punch-pin outer rim is oval outer rim, and the groove on described dent cavity plate is oval-shaped groove.
The groove blade of mould is oval blade on described groove, the finger hole of formation be smooth, mellow and full ellipse
Hole.
