Improvement Tools and Parameter on Coating Manual Machine for Coating Automatic Machine to Reduce Reject

Abstract

NTC (Negative temperature Coefficient) is an electronic component, esistance value changes based on temperature changes and this component is a passive component. Manual coating machine is a machine for coating or wraping NTC (Negative Temperature Coefficient) material. Improvement automation on this machine is for updates machines previously operate by manually become full control by a compute. Manual machine can’t monitor reject and performance machine, because of that author make an improvement on this machine to reduce reject, optimal method, monitoring performance and other. Method using on this proposal is update parameter and make a machine become automatic with new tools like a using motor stepper, pneumatis system, and vibration system. Update parameter doing by study of parameter for best parameter to get more stable quality, for tools define by spect material and spesification part. This proposal expected can make a quality stable, reduce the reject, auto operate and movement machine more optimal. The target for reducing reject make a 0.78% from the target 2%, for consumption of chemical a and chemical b reduce until 48.57% from the target 30%, for OEE on auto coating machine get 88% from the target 85% and cycle time on 1 hour get 4031 pcs on manual caoting machine make a 5379 pcs on auto coating machine for percentage can reduce until 33,44%.
