1、制件的精度與質量，制件的尺寸精度和質量要求是設計模具并確定模具精度與表面質量的主要依據，也是確定模具工作零件加工精度、選取模具標準零部件精度等級，控制模具裝配精度和質量的主要依據。
1. The precision and quality of the parts, the size accuracy and the quality requirements of the parts are the main basis for designing the mould and determining the precision and surface quality of the die, and also the main basis for determining the machining precision of the working parts of the mould, selecting the precision grade of the standard parts and parts of the mold, and controlling the precision and quality of the die assembly.
2、制件的生產批量，制件的生產批量確定模具結構形式、精度等級與表面質量的另一重要依據，因為制件批量越大，要求模具的使用性越好、壽命越長。
2, the production batch of parts, the production batch to determine the mold structure form, precision grade and surface quality of another important basis, because the larger parts, the better use of the mold, the longer life.
3、制件材料的成型性能，金屬板材的塑性指標、彈性模量、屈服強度，抗拉強度等直接影響制件的精度和成形質量，因而也是確定模具工作零件或成形零件精度和質量的重要依據。
3. The molding performance of the material, the plastic index, the modulus of elasticity, the yield www.hupomoju.cn www.lujianbanmoju.cn www.paomoqiegeji.com.cn www.lianjieqi.org.cn www.baowenganggua.cn www.duihanfalan.com.cnstrength and the tensile strength of the sheet metal directly affect the precision and the forming quality of the parts. Therefore, it is also an important basis for determining the precision and quality of the working parts or forming parts of the mould.
4、模具類型與結構形式，不同類型和結構形式的模具，其精度與質量要求也有所不同。
4, mold and structure types, different types and structural forms of molds, their accuracy and quality requirements are also different.
5、模具加工技術水平，因為模具精度和質量最終是靠加工來保證的，所以模具加工設備的加工精度、自動化程度及模具人工的技術水平也是確定模具精度的主要依據之一。
5, the technical level of mold processing, because the precision and quality of the mold are ultimately guaranteed by processing, so the machining precision, the degree of automation and the technical level of the mould manual are also the main basis for determining the precision of the die.
