The need for single-use syringes in Indonesia is predicted to experience a significant growth. Jig and fixture are used to keep up with the skyrocketing demands. The jig and fixture have been designed and manufactured, but unfortunately, there are problems in the clamping and rolling process which was triggered by the surface roughness. The hypothesis had been simulated however, the result has not been validated due to the ongoing pandemic. Thus, this study was conducted to experiment the effect of surface roughness on the rolling process ability. The experiment results will be compared with the previous simulation and analyzed, and also taking a consideration of using polyurethane layer and its effect as a needle scrolling material. The experiment result has shown that the surface roughness affects the needle rolling process. Although, slip does not occur at certain surface roughness values, however it still occurs at other roughnesses. The polyurethane layer tested has shown that it was able to prevent this phenomenon but overtime the surface roughness of the polyurethane also increases. Hence it was not a viable solution
