The Magnum 4500 BFF random semi-automatic case erector is a self-adjusting bottom case forming machine with integrated bottom sealer.  The design utilizes a precision T-Table, adjustable folding assembly, and reliable side belt drives to provide accurate, consistent case forming and tape application to the bottom of random cases.  The machine features dual side belt drives that automatically adjust to the case when a sensor is triggered.  The machine is designed to handle cases from 6” to 20” wide, 3” to Unlimited” tall (top flaps open), and 6” to 24” length.  The system is designed to operate at 8-12 cases per minute depending on case size in random mode, and up to 20 cases per minute in uniform mode.  To allow ergonomic positioning, the pass height can be changed via adjustable legs from 27 inches to 35 inches.  Locking casters are included for portability.

The Magnum 4500 Random BFF is offered as an economical productivity-increasing alternative to manually hand forming cases and hand taping, whether filling directly afterwards on a packaging line or stockpiling cases for later filling.  Expected improvements in efficiency are typically 3-5 times as many cases output per single operator compared to hand folding in the same time period.  In addition, the Magnum 4500 BFF delivers the added benefit of consistent, aesthetically appealing, cost efficient tape application to the bottom of the case.

The primary benefits yielded from the machine are lower labor cost from fewer operators required to produce an equivalent number of cases formed per hour, higher throughput per hour, reduced operator strain from fewer repetitive motions, as well as decreased tape consumption.  This results in full return on equipment investment that can be realized in just months of machine usage – not years.  The system is designed to work with all Highlight case sealers for a complete packing line solution.

The Magnum 4500 Random BFF includes Highlight’s industry-leading 200 series tape head which will accept any 2-inch carton tape and provide optimum case sealing to the bottom of the case.  An optional 3-inch tape head, series 300, is also available for heavy duty applications and is completely interchangeable with the 2” version.  Highlight Magnum tape heads are engineered to be the heaviest duty and most reliable tape heads in the industry.  The user-friendly design allows for easy tape threading, fewer moving parts for minimal maintenance, and simple built-in adjustability for accommodating virtually any case type.
