        应当 according to production cycle for mold necessary 清洁. mold from pressure machine in rear need mold gas 孔以清 remove mold and sheet/plate non key/critical full oxidation material and 锈迹,以 anti its slow 腐蚀钢材 surface and 边缘. very more lower,即 make 清洁完毕,一 未 coating or easy mold surface very fast again 次出现锈迹. therefore,即 make very long time for anti mold 进行刷洗,但 is surface still can full 避免.

        当 molding process as formed rear usually in mold upper lower material or material, for/regarding different types type material, most 终清洗 requirements 也会不 same. ratio polyvinyl chloride (PVC) this category of resin generate chlorine hydrogen gas 体, from 而腐蚀 multiple Model/Grade mold 钢. other 一 残余 material is from flame retardant and resistant oxidation agent in separation 离出, can is for/regarding 钢材造 formed 腐蚀. also has 一 颜 material color agent make 钢材生锈, and very difficult remove. 甚至普通 封存 water if in 未经处理 mold surface long time,同样会 for mold formed loss 害.

         very more mold belt/tape has “自我清洁式” 通 gas tube/pipe 路, this tube/pipe tool has very high gloss degree. through for gas 孔进行清洗 and light, make its to SPI #A3 抛 light degree, or through abrasion or abrasion, will material 排放至通 gas tube/pipe waste 区域,以 anti 止残余 material viscous coarse machine base/seat surface. if as using/adopting coarse 粒 刷洗垫 sheet/slice, rigid 砂布, 砂纸, abrasion or belt/tape nylon 鬃毛, copper or made for mold 进行人工研 abrasion 时,就会造 formed mold degree 清洁.

         generally,当 utilizing hard 塑科, fine 珠, housing/shell and aluminum material and other as is abrasion agent for mold surface high pressure powder 碎清洗时, if frequency use this abrasion agent or use 不当, this abrasion methods make mold surface generate 孔隙而 easy 于残余 material its upper,导致 generate more more material, abrasion loss, or 者导致 mold fracture or flash/burrs and other phenomenon,反而 more 不利于 mold 清洗.

         is has reduce mold abrasion loss,我们应该找 to combined mold and processing process equipment.
