Shanghai Daoqin Plastics Co., Ltd.

product usually is due to in 拼缝处 temperature degree low, pressure small formed. ⑴ temperature degree issues: ① material temperature degree low; ② nozzle temperature degree low; ③ mold temperature low; ④拼缝处 mold temperature low; ⑤ plastics melt temperature degree 不均. ⑵ injection molding processing issues: ① injection pressure low: ② injection speed degree slow. (3) injection molding processing mold issues: <1>拼缝处排 gas defect; <2>部 parts gas defect; <3> separation runner small; <4> gate small; <5>三 runner Imported 直径太 small; <6> nozzle small; <7> gate 离拼缝处太远, can increase gate; <8> products thick thin, formed solid 化; <9> type 芯偏移, formed mono thin; <10>模子偏移, formed mono thin <11> made parts in 拼缝处太 thin, add thick; <12>充模 speed rate and other; <13>充模 material in 断. (4) equipment issues: ①塑化容 amount small; ② material in pressure loss large (柱塞式注 pressure machine). ⑹ material material issues: ① material material 污染; ② material material flow property 太差, add lubricant improvement flow property.
