If melted plastic leaks from the bottom of your vertical injection blow molding machine, take heart. Bishop Tool & Design Inc. has an answer: a screw called Vibes2.
Bishop Tool of Mount Holly, N.J., designs and makes single-stage screws for extrusion, blow molding and injection molding. Vibes2 has undergone a six-year field test.
The design includes corrected opposing pressures with a special deflection angle, which creates an impassable area that contains the material.
In all test cases, the configuration has eliminated leakage of the homogenized compound, Bishop Tool said.
The company even installed the screw in worn barrels where processors were losing as much as 25 percent of the material. The Vibes2 screw has cut that amount to less than 1 percent.
Bishop Tool can build new Vibes2 screws or modify the shank of an existing screw when it is being rebuilt.
