Shanghai Daoqin Plastics Co., Ltd.

        一直以, is improve/increase product strong/high degree and resistant temperature property and other property can, use glass fiber (GF) for plastics reinforcement modified formed non 常不错 selection. a large amount of 事实也证明 glass fiber (GF) belt/tape good property can. is, glass fiber (GF) and plastics 本身就 is types different material, 自然也就 generate versus property issues.

         glass fiber (GF) outer 露(or fiber exposure)就 is versus property issues 直接体现. glass fiber (GF) outer is add material injection molding processing process in 经常碰 to 且困扰诸 more 朋友们 一 issues.

         that glass fiber (GF) outer 露究竟 is how generate 呢?简而言之, from glass fiber (GF) upper glass fiber (GF) has long and short separation, is 一束一束, is white. add material is will glass fiber (GF) and resin blending pelletizing formed.

         in 射胶 时候, material flow is similar liquid flow methods. large 家应该看 河流里面, in 河流里 has 一 树枝 and other material 时, 经常会 in 沿岸边 has this category of 依附河岸而停留. if in injection molding in, is glass fiber (GF) outer 露.

         this is is glass fiber (GF) versus for/regarding plastics flow property need very more, plastics in mold in flow is from in front 流, 俩边往 outer methods flow, therefore flow property most good is to most front 面, flow property good 就会停留 in mold surface.

         meanwhile, glass fiber (GF) has promote crystallization function, 而PP, PA都 belongs to crystallization property material. crystallization fast cooling fast; cooling fast, glass fiber (GF) difficult by resin and cover/cap 住, that 么就容 easy generate glass fiber (GF) outer 露.

         currently usually solutions main/primary has below/following types:

        一, material 方面:

        1, glass fiber and versus property, for glass fiber (GF) surface treatment, add coupling agent and grafting material;

        2, add lubricant, lubricant main/primary is to glass fiber (GF) dispersion issues and lubricant tool has outer lubricated function, in molding 时候容 easy to products surface formed light slip 一层.

        3, also has other filling agent has improvement 效果, this 里就不 again 一一列举.

        二, injection molding processing 方面:

        1, improve/increase material temperature and mold temperature;

        2, high pressure high speed;

        3, using/adopting fast speed cold hot molding technology (RHCM).

        因 is if melt plastics in 接触模壁时 solid fast, glass fiber method by full 包覆, generate surface fiber exposure phenomenon. for/regarding RHCM molding, due to high mold temperature make type interface glass fiber full can by plastics melt 包覆, due to 该部位处于熔 melt 状态, make glass fiber toward 趋于一致, ensure shrinkage uniform property, ensure molding quality.

        三, mold 方面

         will product appearance 面刻意做 formed light or 蚀纹面, decrease/reduce glass fiber (GF) outer 露 视觉 reaction.

         currently, upper use add material most more is nylon add material. due to glass fiber (GF) outer 露, make type product application to 一定 限 made, currently main applications high strength structural parts. is use add material cosmetic parts, basic upper is light or 蚀纹面(例如 power tools), is add material difficult to appearance.
