         for mold 进行抛 light main/primary has 两:

        一 is increase plastics mold light degree, degree;二 is make mold more easy demolding.

         in 进行抛 light 时, generally use coarse for machine processing mold type surface coarse abrasion, abrasion machine add tool 刀痕, rear again use fine 油石打 abrasion coarse 油石打 abrasion 痕迹, rear again use fine for fine 油石打 abrasion surface again 进行打 abrasion, most rear again use light or abrasion for mold type surface most rear light abrasion, most rear to light 亮如镜 效果.

         day active in, Common plastics mold light methods has types:

        1 machine light

         machine light is 靠切削, material surface property deformation by light rear 凸部而 to slip 面 抛 light methods, generally use strip/profile, 羊毛轮, and other, 以手工操 as is 主, parts 如回转体 surface, can use and other 辅助工 tool, surface quality requirements high can using/adopting ultra- 精研抛 methods.

         ultra- 精研抛 is using/adopting made abrasion tool, in has abrasion material liquid in, pressure in parts by processing surface upper, as high speed 旋转运动. utilizing technology can to Ra0.008μm surface coarse degree, is various light methods in most high. optical sheet/slice mold using/adopting this type of methods.

        2 chemical light

         chemical light is let material in chemical in surface micro 凸出 部 separation relatively separation excellent solvent understanding, from to slip 面. this type of methods main/primary advantages is complex equipment, can light complex parts, can meanwhile light very more parts, efficiency high. chemical light core issues is light liquid made. chemical light to surface coarse degree generally is 数10μm.

        3 electrical understanding light

         electrical understanding light basic and chemical light same, selection property solvent understanding material surface micro small 凸出部 separation, make surface light slip. and chemical light versus ratio, can remove anionic reaction effect/influence, relatively good. electrical chemical light process separation is 两步: (1) macro 平整. solvent understanding material toward electrical understanding liquid in expand dispersion, material surface coarse degree decline, Ra>1μm; (2) micro light 平整. cationic 极极化, surface light degree improve/increase, Ra<1μm.

        4 ultra- 声波抛 light

         will parts abrasion material liquid in, 并一起置于 ultra- 声波场 in, ultra- 声波 振动 function, make abrasion material in parts surface abrasion light. ultra- 声波 processing macro force small, 不会引起工 parts deformation, 但工装 made as and relatively difficult.

         ultra- 声波 processing can and chemical or electrical chemical methods combined. in solvent liquid 腐蚀, electrical understanding upper, again add ultra- 声波振动搅拌 solvent liquid, make parts surface solvent understanding material 脱离, surface 附近 腐蚀 or electrical understanding uniform; ultra- 声波 in liquid in function also can made process, surface light 亮化.

        5 流体抛 light

        流体抛 light, is high speed flow liquid and its belt/tape abrasion 粒冲刷工 parts surface to light 目. commonly used methods has: abrasion material processing, liquid 体喷射 processing, 流体动 force abrasion and other.

        流体动 force abrasion is liquid pressure 驱动, make belt/tape abrasion liquid 体介质 high speed 往复流 工 parts surface. main/primary using/adopting in relatively low pressure lower property good 特殊化 combined material (polymer material 质)并掺 upper abrasion material made formed, abrasion material can using/adopting carbon silicon powder 末.

        6 magnetic abrasion light

         magnetic abrasion light, is utilizing magnetic property abrasion material in magnetic function lower formed abrasion material 刷, for parts abrasion processing. this type of methods processing efficiency high, quality good, processing conditions easy control, as conditions good. using/adopting combined abrasion material, surface coarse degree can to Ra0.1μm.
