Analysis of the solution in the plastics injection tube using theoretical analysis of defects and their impact on quality FMEA

Abstract

 Injection molding process with Production process. Start by getting Pre pane Ingredients for a plastic injection molding of plastic tubes from the experimental fact. Bake resins Plastic injection tube quality inspection to be released to the customers who have ordered the production of plastic tubes in various sizes. The study found that most of the problems from the injection tube is not completely trouble-finned specimen spot colors are not standardized. Due to such problems, there is a variety of reasons. It needs to be analyzed in order to fix the problem. The cause and effect diagram this analysis is based on the production of plastic tubes 4M man machine materials and method. The common problem is that all 10 leading causes of air pressure. Equipment failure age of pressure injection of too much or too little. Bake resins longer period. Inexperience with operating machinery. Irresponsible in front of the responsible Plastic moisture accumulation Polymers are contaminated by foreign substances and resin color does not meet standards.

Research study, analyzed hare collected data the defects and their impact on the quality of the injection tube. Considering the shortcomings of the RPN more than 100 points to make corrections. Found that the cause of the defect needs to be revised number 3 cause of defects, including 10 cause did’t tubes did not meet the required standards. Term stability in injection molding is injection and the force of the wind is not uniform. The recommendations to rectify the problem, including the 140-185
