History

As Chairman of Bison, Ron Bullock has opened the company to the global market, expanded Bison's overall product line, and established a Research and Development Center. Since the Bullock's acquisition of the company, Bison's sales volume has more than quadrupled.

PMDC Motor Acquisition

Bison Gear and Engineering of St. Charles, Illinois has enhanced its marketing leadership with the consolidation of the Bison Electric Company formerly located in Elgin, Illinois.

With this relocation and consolidation into the St. Charles facility in 2002, it has shortened lead-times to our customers while eliminating waste with excess material handling with our manufacturing process. With this acquisition, we were able to retain the expertise and experience of the motor division employees.

Lean Manufacturing

The Total Quality Management (TQM) program evolved in 1999 to a Lean Manufacturing strategy using the tools of Lean such as 5-S, Kaizen Blitzes, Kanban, and Single Minute Exchange Of Dies (SMED) as the primary means of improvement. Initially, Bison engaged in the training of its associates in Lean Methodologies and then moved it into motion within the manufacturing facility. Bison utilized this knowledge to evaluate the work processes to convert the manufacturing processes where components were made in batches, into one-piece-flow cellular manufacturing. In addition inventory and production scheduling began to be converted from a Material Requirements Planning (MRP) system into Kanban arrangements.

Value Stream Maps have been used as an important tool to identify any activities that do not add value to the process (value as determined by the customer). Dozens of Kaizen events were then eliminating waste throughout the entire value stream that has resulted in providing products with shorter lead times and fewer defects using less human effort, inventory, and costs.
