1.前言塑料及橡胶等的模塑成型品在工业上大量使用。优质的模塑成型品除依靠高超的成型加工技木外,还得依赖表面光洁的金属模具。然而这些金属模具的光洁表面却容易生锈或受异物污染和划伤,从而影响模塑产品的质量和使用性能。因此,有关人员应依照防锈规则,对金属模具进行严格的防锈管理。事实告诉我们,加工越精密,结构越复杂的金属模具,应力腐蚀的可能性就越大,
1. Introduction Molded molded products such as plastic and rubber are widely used in industry. In addition to high quality molding products rely on the advanced molding technology, have to rely on the surface smooth metal mold. However, the smooth surface of these metal molds is easily rusty or contaminated and scratched by foreign matter, thereby affecting the quality and usability of molded products. Therefore, the staff should be in accordance with anti-rust rules, the metal mold strict rust management. The fact tells us that the more sophisticated the machining, the more complex the structure of the metal mold, the greater the possibility of stress corrosion,
