Usulan Perbaikan Kualitas Defect pada Proses Seal di Bagian Solid Quarter (Studi Kasus Perusahaan Automotive Rubber)

Abstract

Quality improvement approaches and methodologies have been developed through previous
research. This study proposes quality improvement for automotive rubber companies as a case
study in which the largest percentage of NGs in item-B in the seal, compact / quarterly
departments during the January-June 2019 period was found. Based on the results of the study
there are differences, initially suspected and explained through the P control map, that is, there
is a point outside the control limit (UCL), which is the 20th observation. Identify possible causes
of inaccuracy in 5 factors, namely (low engine temperature, decreased engine pressure, and
compressor mold holes), method (giving toluene liquid in mold before inserting material at
maturity), material (less material coating and end of profile cuts or dirty joints), people
(pursuing production targets and new employees who are still in job training), environment
(night lighting). Get repair with 5W + 1H method.
