         specific issues specific analysis, solution tensile type mold 拉伤也 is has specific methods, in formed process in 应依照 decrease small viscous abrasion loss basic 原则, through 改变接触副 property as is 出发点. in formed parts Raw Materials 方面, parts and mold between, mold 方面特殊 for 待.

        首先 is by formed parts Raw Materials 方面. through for Raw Materials surface treatment,如 for Raw Materials 进行磷化, or other surface treatment, make by formed material surface formed non metal 模层, can large large decrease light or remove parts 拉伤, this type of methods cost relatively high,并 need add another production equipment and increase production 工序,尽 tube/pipe this type of methods has has 效果,实际 production in application very less.

         in parts and mold between add 一层PVC之 type film, has can solution parts issues. for/regarding production through machine can to 连续供 to film,而 for/regarding cycle production pressure equipment,每 production parts parts add film, effect/influence production efficiency,此 methods generally cost very high, also production a large amount of waste material, for/regarding small amount large type parts production using/adopting types methods is can 取. in formed negative very small combined, has through add lubricated or add EP additives lubricated can solution parts issues.

        实际 already 经证明现今广泛 by using/adopting methods is through mold 凸, 凹墨材 material or for mold 凸, 凹模进行 surface treatment, make by formed material and 凸, this 样接触副 property 质发生改变.

         solution parts and mold 凸, surface issues according to selection versus for methods. ratio parts and large small, production amount, by processing material types type and other selection application methods. in has solution issues methods in,以 using/adopting hard alloy is mold material and for mold 凸, surface chemical gas versus 沉积, TD覆层处理 is most good. its in also 以TD覆层处理 property ratio most high.
