| Summary: | 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 |
