摘  要
 塑料制品廣泛用于機械配件、儀表工業、消費電子類產品、建筑、文教、農業、醫療衛生及日常生活等各個領域。目前各個行業對塑料制品的質量要求越來越高，這就要求生產過程控制越來越精確。作為操作者，我們必須對注塑機的操作規程有足夠的認識，并逐一掌握，確保能準確的運行機器，并保證人身安全。
 在經過對操作規程的充分學習之后，我們還要了解各種注塑機的分類以及特點，方便今后對生產不同產品所需的機器進行辨認區分。成型工藝是另一項重要的課目，要想產品的質量高，精度準確，就必須搞清楚機器是怎么運行的，各個部件是怎么協同合作的。作為主要的生產成品的機器，越是熟悉其成型原理，越能操作好它，越能生產出令人滿意的產品。另外，我們還要學會對造成塑件缺陷原因進行識別，準確的找到根源并能迅速的解決問題。
 所以，本文就注塑機的操作規程、成型工藝進行了重點分析，并對塑機分類以及塑件缺陷原因進行相關的學習。

Abstract
Plastic products widely used in machinery parts, industrial instrumentation, consumer electronics products, construction, culture, education, agriculture, health and daily life, and other fields. Present in all sectors of the quality of plastic products have become increasingly demanding, requiring more and more precise process control. As operator, we have the operational procedures of the injection molding machine to have sufficient knowledge and grasp one by one, to ensure accurate operation of the machine, and to ensure personal safety.     After a full study on the operational procedures, we also understand the classification of the various features of injection molding machines, to facilitate the future production of the machines required for different products to identify the distinction. Molding process is another important subjects, to products of high quality, precision and accurate, we must figure out how the machine is running, how the various parts of synergy. The production of finished products as the main machine, the more familiar with the shape theory, the more good it can operate, the more it can produce a satisfactory product. In addition, we have to learn the reasons which caused the plastic parts to identify defects and accurate and can quickly find the root causes of problems.     Therefore, this operation rules on the injection molding machine, molding process was analyzed, and classification as well as plastic parts presses associated defects of learning.
