Optimised reduction of surgical gloves pinholes using forward search method

This research investigates the factors that affect the existence of pinholes in surgical gloves during the manufacturing process. Since eight factors affect the existence of pinholes in surgical gloves, a two-level fractional factorial design 2(8-4) was used to study the main effects and the first-o...
