         extrusion mold use non 常普遍, if in use 时, selection has attention/notes to quality excellent poor,会严 heavy effect/influence to extrusion mold positive use, is let mold to good use, lower provide has 关判断 extrusion mold quality good bad specific methods.

        一,看看 this mold thick degree, although mold need large force use or is other poor ring 境,但 is is more 次 倒模 demolding, mold is separation easy loss consumption, deformation, bad,而 need solution this issues 根本做 method is add thick mold thick degree, therefore thick degree can obvious separation mold 档次.

        二,看看 extrusion mold specifications is standards, good mold can will production extrusion plastics product dimensions control in 零点几 mm 误差当 in,而 poor mold production product 误差会达 to mm is cm.

        三,查看整 mold and 做工, good mold is inner outer 两面都十 separation light slip,看起 富 has gloss, but also micro lubricating 沉手, poor mold can can surface has or is 坑坑洼洼,两者一 ratio is high lower 立现.
