Baker Manufacturing Uses 5S, Plant Layout and Lean to Streamline Growth


Founded in 1873, Baker Manufacturing Co. LLC is located in Evansville, Wisconsin, and consists of three divisions: Baker Casting Division, which pours gray and ductile iron castings; Haight Pump Division, which produces gear pumps; and Baker Water Systems Division, which manufactures products for residential, municipal/industrial, and environmental use. Baker Manufacturing Co. acquired Campbell Manufacturing in 2008. Baker employs between 100 and 200 people across the divisions.

The Challenge

Baker needed to increase capacity and reduce throughput in its industrial water systems welding department to meet existing and future demand. For help the company turned to WMEP Manufacturing Solutions, part of the Wisconsin MEP and the MEP National Network™, a trusted advisor who has been delivering successful projects at Baker Manufacturing since 2005.

We enlisted the help of WMEP to provide training and guidance on 5S organization to a young welding team that was facing extremely high sales order growth. WMEP came in for six sessions over the course of two months. This compressed timeline definitely energized the weld team to make the needed changes in their areas. There had been turnover with the team and this focus on organization and streamlining the area bonded them together to make good improvements.

MEP's Role

Baker needed to increase capacity, which required adding another welder and rearranging the work area. To reduce throughput time, the welding process needed to be more efficient and reduce the waste associated with an inefficient layout. Improving throughput time and decreasing lead times created an opportunity to significantly increase sales. By reducing lead times, Baker can attract more customers and improve market share.

To develop a weld work layout area, WMEP Manufacturing Solutions conducted an analysis and design that involved: creating a charter; collecting and analyzing data; developing a matrix of product families and process steps; creating a value stream map of current processes; developing future state flows using lean principles; and identifying process change requirements. A second phase involved creating a plant layout that considered future state flows using lean principles, having the project team agree on a proposed layout and having the team report out to management. Next came the facilitation of a 5S workplace organization method.
