注塑模具的塑料制品是否符合注射成型加工原理进行分析研究，其中包括对制品几何形状、尺寸精度及外观要求等，进行必要的讨论，尽量避免在模具制造中不需要的东西。
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.
济南注塑加工，除了良好的加工设备和熟练的模具工人外，还有一个很重要的因素就是要有好的模具设计，尤其对于复杂的模具，模具设计的优劣占80%以上。一种优秀的模具设计是：在满足客人要求的前提下，加工成本低，加工难度小，加工时间短。
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.
要具备注塑机、模具结构、加工工艺及模具本身的加工能力。为提高模具设计水平，应采取以下措施：
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.了解每一套模具设计的细节，了解每一套模具的用途。
Understand the details of each mold design, understand the purpose of each mold.
2.在设计时多参考以前类似的设计，并且对模具加工和产品生产有理解，从中吸取经验教训。
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.多了解注塑机的工作过程，以加深模具与注塑机的联系。
Know more about the working process of injection molding machine to deepen the relationship between mold and injection molding machine.
4.到工厂去了解加工工艺，了解每种加工方法的特点和局限性。
Go to the factory to understand the processing technology, understand the characteristics and limitations of each processing method.
5.了解试模结果及自己设计模具的模具改型情况，吸取教训。
Understand the test results and mold modification of their own design mold, draw lessons.
6.在设计时，尽量使用较成功的模具结构。
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.了解更多的模具进水对产品的影响。
Learn more about the impact of mold water intake on the product.
济南注塑加工开始到装配结束只是其全部制造过程的70%~80%。由于预缩与实际收缩不一致而引起的误差，脱模过程顺利进行，冷却效果如何，特别是浇口尺寸、位置、形状对产品精度和外观的影响都要通过试模进行检验。所以，试模是检查模具是否合格和选择最佳成型工艺必不可少的一步。
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.
