The quality of Jinan injection mold can be evaluated in the following aspects:

注塑产品大小尺寸的稳定性、符合性，产品表面的光洁程度及是否美观、塑料原材料的利用率等；

The stability and conformity of the size of injection molded products, the smoothness and beauty of the product surface, and the utilization rate of plastic raw materials;

注塑模具的寿命：在确保产品质量的前提下，模具能使用的循环的次数也可以称生产的产品的数量；

Life of injection mold: on the premise of ensuring product quality, the number of cycles that the mold can use can also be called the number of products produced;

模具的易用性：是否方便使用、脱模是否容易、生产辅助时间(等待时间)尽可能的短；以及模具维修成本高低和模维修周期长短等。

Ease of use of the mold: whether it is the most convenient to use, whether it is easy to demould, and whether the production auxiliary time (waiting time) is as short as possible; And mold maintenance cost and mold maintenance cycle length.

提高模具质量的基本的方法就是模具设计时要考虑周全，包括模具材料的选用，模具结构的可使用性及性，模具零件的可加工性及模具维修的方便性，这些在设计时都要考虑到,权衡综合性能,有利因素化。

The basic method to improve the quality of the mold is to consider comprehensively in the mold design, including the selection of mold materials, the usability and safety of the mold structure, the machinability of mold parts and the convenience of mold maintenance. These should be considered in the design, weigh the comprehensive performance and maximize the favorable factors.

模具的制造过程也是确保模具质量很重要的一节，模具制造过程中的加工方法和加工精度也会影响到模具的使用寿命及易用性。各零部件的精度直接影响到模具整体装配情况,考虑到精度不可能达到100%，所以要通过改善零件的加工方法，提高模具钳工在模具磨配过程中的技术水平，来提高模具零件的加工精度。对模具主要成形零部件进行表面强化，以提高模具零件表面耐磨性，从而更好地提高模具质量。

The mold manufacturing process is also a very important section to ensure the mold quality. The machining method and machining accuracy in the mold manufacturing process will also affect the service life and ease of use of the mold. The accuracy of each part directly affects the overall assembly of the mold. Considering that the accuracy cannot reach 100%, it is necessary to improve the processing accuracy of mold parts by improving the processing method of parts and improving the technical level of mold fitter in the process of mold grinding. Strengthen the surface of the main formed parts of the die to improve the wear resistance of the surface of the die parts, so as to better improve the quality of the die.

模具的正确使用与维护，也是提高模具质量的一大因素。如：模具的安装调试方式应恰当，在有热流道的情况下，电源接线要正确，冷却水路要满足设计要求，模具在生产中注塑机、压铸机、压力机的参数需与设计要求相符合等等。在正确使用模具时，还需对模具进行定期维护保养，模具的导柱、导套及其他有相对运动的部位应经常加注润滑油，对于锻模、塑料模、压铸模之类模具在每模成形前都应将润滑剂或起模剂喷涂于成形零件表面。

The correct use and maintenance of molds is also a major factor to improve the quality of molds. For example, the installation and commissioning mode of the mold should be appropriate. In the case of hot runner, the power wiring should be correct, the cooling water path should meet the design requirements, and the parameters of injection molding machine, die casting machine and press should meet the design requirements in the production of the mold. When using the mold correctly, it is also necessary to maintain the mold regularly. The guide post, guide sleeve and other parts with relative movement of the mold should be often filled with lubricating oil. For dies such as forging die, plastic die and die-casting die, lubricant or molding agent should be sprayed on the surface of formed parts before forming each die.
