注塑模具的塑料制品是否符合注射成型加工原理進行分析研究，其中包括對制品幾何形狀、尺寸精度及外觀要求等，進行必要的討論，盡量避免在模具制造中不需要的東西。
Whether the plastic products of injection mold conform to the principle of injection molding is analyzed and studied, including the necessary discussion on the geometric shape, dimensional accuracy and appearance requirements of the products, etc. , try to avoid things that are not needed in die making.
濟南注塑加工，除了良好的加工設備和熟練的模具工人外，還有一個很重要的因素就是要有好的模具設計，尤其對于復雜的模具，模具設計的優劣占80%以上。一種優秀的模具設計是：在滿足客人要求的前提下，加工成本低，加工難度小，加工時間短。
Jinan injection molding, in addition to good processing equipment and skilled mold workers, there is a very important factor is to have a good mold design, especially for complex mold, mold design of the pros and cons account for more than 80% . An excellent mold design is: to meet the requirements of the premise of the guests, low processing costs, processing difficulties, processing time is short.
要具備注塑機、模具結構、加工工藝及模具本身的加工能力。為提高模具設計水平，應采取以下措施：
Must have the injection molding machine, the mold structure, the processing craft and the mold itself processing ability. In order to improve the mould design level, the following measures should be taken:
1.了解每一套模具設計的細節，了解每一套模具的用途。
Understand the details of each mold design, understand the purpose of each mold.
2.在設計時多參考以前類似的設計，并且對模具加工和產品生產有理解，從中吸取經驗教訓。
In the design of more reference to the previous similar design, and die processing and product production have an understanding, learn from the experience.
3.多了解注塑機的工作過程，以加深模具與注塑機的聯系。
Know more about the working process of injection molding machine to deepen the relationship between mold and injection molding machine.
4.到工廠去了解加工工藝，了解每種加工方法的特點和局限性。
Go to the factory to understand the processing technology, understand the characteristics and limitations of each processing method.
5.了解試模結果及自己設計模具的模具改型情況，吸取教訓。
Understand the test results and mold modification of their own design mold, draw lessons.
6.在設計時，盡量使用較成功的模具結構。
In the design, try to use a more successful mold structure. Kill. Learn more about the impact of mold water intake on the product.
7.了解更多的模具進水對產品的影響。
Learn more about the impact of mold water intake on the product.
濟南注塑加工開始到裝配結束只是其全部制造過程的70%~80%。由于預縮與實際收縮不一致而引起的誤差，脫模過程順利進行，冷卻效果如何，特別是澆口尺寸、位置、形狀對產品精度和外觀的影響都要通過試模進行檢驗。所以，試模是檢查模具是否合格和選擇最佳成型工藝必不可少的一步。
It is only 70% ~ 80% of the whole manufacturing process from the beginning of injection molding to the end of assembly in Jinan. Due to the error caused by the inconsistency between the pre-shrinkage and the actual shrinkage, the demoulding process is carried out smoothly, and the cooling effect, especially the influence of gate size, position and shape on the precision and appearance of the product, must be tested by the trial die. Therefore, die test is to check whether the mold is qualified and the selection of the best molding process is an essential step.
