Shanghai Daoqin Plastics Co., Ltd.

         is ensure plastics parts surface defect, obvious toward structure and internal stress, in design and manufacturing mold meet/satisfy lower requirements:

        (1) mold material need use copper alloy, use high quality true 空铸钢 manufacturing, type surface 应沿出模 direction light to light 亮, degree small 于0.2m, surface most good hard 铬.

        (2)塑 parts surface 如实反映 mold cavity surface, therefore electroplating parts mold cavity separation light 洁, mold cavity surface coarse degree ratio made parts surface surface coarse degree high 1～2 grade.

        (3) separation type 面, weld lines and type 芯镶嵌线不 can design in electroplating upper.

        (4) gate design in made parts most thick 部位. is anti material mold cavity cooling fast, gate amount large (约 ratio injection large 1O%), most good using/adopting 圆形截面 gate and 浇道, long degree short 一.

        (5)应留 has gas 孔, in made parts surface generate gas filament, bubbles and other 疵病.

        (6) selection ejection machine 构时应 ensure made parts demolding.
