Case study: Understanding Human Factors and Materials in selection of Slitters (A project undertaken as an Intern)
Manufacturing speeds, flexibility and capabilities, and costs of outsource slitters are far often key determinants in traditional supplier selection for manufacturing. While these factors are important, they often overlook the operating competences and areas of innovation that can benefit the supplier-vendor relationship.
This project emphasises other aspects crucial in the evaluation of outsource slitters- human factors and materials management processes. These factors have a substantial impact in the operating competencies of the supplier. Without looking into these factors, the client often has to deal with quality and delivery issues due to manufacturing defects and downtime that would have offset upfront cost savings.

Case Study: Understanding Human Factors and Materials
Use the right method of cut for the right material and right cut!
Stefan Choo 22
Q&A/ Objections?“It’s much cheaper, easier and saves time
to choose a slitter who has machines that run at fast speeds and promise to slit across most materials.”
“We outsourced to them since it’s not our core capability, they should serve us accordingly. I don’t see any point in investing more time and resources to study their processes”

Glossary of terms Converting companies are companies that specialize in combining raw
materials such as polyesters, adhesives, silicones, tapes, foams, plastics, felts, rubbers, liners and metals, as well as other materials, to create new products. (Source: Wikipedia)
Web speed: (inferred) Feed speed of the substrate material that is to be processed. The web is usually a long thin flexible material passed over rollers.
* Web handling is the art and science of getting a web through a machine with maximum productivity and minimum waste.
Differential core technologies: Technology that allows for uneven cuts to be processed by the slitter
Slit Edge: The edge of a coil or sheet after being fed through a highly tempered knives located on the slitter head. The edge of slit coils has tighter tolerances than normal mill run edges.
Nip: a pinching force between two surfaces. In manufacturing,
