Belvac Production Machinery Inc. developed a machine to finish two-up, neck-to-neck polyolefin container “logs” made by a major North American blow molder.
The two extrusion blow molded bottles, joined in a dumbbell-shaped part, have to be separated and trimmed. Belvac said its rotary machine, the MT/F 200, trims out the centerpiece, or moil, sets the containers in an upright position and smooths out the rough edges on both the inner neck finish and the top sealing surface. It can finish 100 logs, or 200 containers, per minute.
Belvac, in Lynchburg, Va., said the customer, which it declined to identify, has ordered a large number of the machines to replace its current in-line and horizontal spin trimmers, which have resulted in high scrap rates and machine downtime.
Belvac is limiting sales of the trimmer design to plants outside North America. But the equipment maker said the restriction does not cover its range of trimming and finishing systems.
