This design also takes into account the problem of personnel safety and environmental protection. I stated some protection for problems that may arise, such as fire prevention measures, anti-static measures and personnel protective measures. During the production process, the production staff have to comply with the operation procedures strictly, make good toxicity protection measures, and often participate in the relevant training to understand the relevant information.
According to the assignment, I accomplished the design. Throughout the design, I have a comprehensive understanding of the process of extrusion. Combining the professional knowledge with my own experience in cognitive practice, I will flexibly apply them to my future.
Teacher Nan Gao, who guided the design, has put forward a lot of valuable comments and positive suggestions to help me improve the design quality. Besides, she was strict with me and guide me to broaden thinking. She helped me a lot when I had encountered a bottleneck. Here, please let me express my high praise and respect for the Teacher Gao! During the design process, the students together to explore the design showed me their kindness. I also wish to express my heartfelt thanks.
Due to the knowledge about the PP reinforced with short glass fibers workshop is so amplitude, and my knowledge and experience is so limited. Please make comments on the design’s mistakes,every teachers.
