Shanghai Daoqin Plastics Co., Ltd.

in plastics made parts inner outer surface demolding direction, design demolding degree 以利于 demolding, 否则会发生 demolding difficult or ejection bad, scratch plastics made parts.

　　 commonly used degree value is 1~1.5°, can small to 0.5°. use upper has requirements 时, degree can using/adopting outer surface 5', inner surface 10'~20'. parts high degree large 时, can 允许不 design degree.

　　 made parts upper or add strong/high mono 边应该 has 4~5° degree; made parts demolding direction has several or 呈矩形格子状而 make demolding retardant force add large 时, use 4~5° degree; belt/tape has leather 花纹时应 has 4~6° demolding degree.

　　 generally lower, if degree 不妨碍 products use, can will degree value large 一.

　　 has is in mold opening let made parts in cationic upper or anionic inner, has decrease small 该边 斜 degree, or add large for 边 斜 degree.

　　 has requirements dimensions degree value can in made parts scope/range inner, can in scope/range outer.

　　 pressure made molding relatively large deep degree products 时, requirements anionic cationic need has 足够 斜 degree, also amount let cationic 模 斜 degree large anionic 模 斜 degree, this made parts lower 部 侧壁 thick degree ratio upper thick degree large. in pressure combined 时, due to function make made parts upper density to ensure.
