Shanghai Daoqin Plastics Co., Ltd.

         advantages

         shrink short cycle

         made parts molding cycle shrink short, has system cooling time made, made parts molding solid rear can and ejection. many use hot runner mold production thin parts molding cycle can in 5秒钟 below/following.

        节省 plastics

         in pure hot runner mold in has cold 浇道, therefore production material. this for/regarding plastics price application project especially heavy large. upper, upper main/primary hot runner production 厂商均 in world upper and plastics raw materials price year to development. is hot runner technology is decrease/reduce material reduce material has 效途径.

         decrease/reduce waste product

         decrease/reduce waste product, improve/increase product quality. in hot runner mold molding process in, plastics melt temperature degree in runner system to control. plastics can more is uniform 一致 状态流入各 mold cavity, its is quality parts. hot runner molding parts gate quality good, demolding rear residual stress low, parts deformation small.

         production 自动化

        消 remove rear 续工序, has production 自动化. made parts hot runner mold molding rear is formed product, 无需修剪 gate and recycling processing cold and other 工序. has production 自动化. outer very more product production 厂家均 will hot runner and 自动化结 combined 起 以 large degree improve/increase production efficiency. many plastics molding process is in hot runner technology upper development 起. 如PET预 molding made as, in mold in more color 共注, multiple material process, STACK MOLD and other.

         disadvantages

        尽 tube/pipe and cold runner mold versus ratio, hot runner mold has many significantly advantages, mold use need understanding hot runner mold disadvantages. 概括起 has below/following 几点.

         cost upper rise

         hot runner parts price comparison 贵, hot runner mold cost can can large degree increase high. if parts output/production volume small, mold tool cost ratio/proportion high, upper 不划算. mold micro editor for many development China mold use 户, hot runner system price is effect/influence hot runner mold use main/primary issues 之一.

         equipment requirements high

         made as process equipment requirements high, hot runner mold need precision processing machine as ensure. hot runner system and mold formed and combined requirements is 严格, mold in production process in 会出现 very more heavy issues. plastics 密封不 good plastics loss bad hot runner parts in production, nozzle parts and gate versus for 位置不 good products quality heavy decline and other.

        操 as repair complex

         and cold runner mold versus ratio, hot runner mold as repair complex. use as 不当极 easy loss bad hot runner parts, make production method 进行, formed large loss 失. for/regarding hot runner mold new use 户, need relatively long time use experience.
