injection molding parts processing generate flash solutions:
flash large more in mold separation combined upper, 如动模 and separation type 面, slip block slip 配位置, parts 缝隙, 顶针杆孔隙 and other 处. flash in very large degree upper is due to mold defect or machine clamping force large, generate force large clamping force 时, mold 胀开, make plastics 溢出, formed flash. (一), in molding process conditions causes 1） plastics melt degree low can can flash, melt temperature degree high or mold temperature high and other, has can can formed flash generate. 2）计 amount 不准确 3） plastics speed degree fast and pressure large easy formed flash 4） using/adopting more grade speed degree injection (二), mold and products design causes 1） mold separation type degree 差 2） mold and material 配置不 combined 理 （三）, material causes flash 1）PP, PE, PA and other plastics melt degree low, can force strong/high easy generate flash; 2）PA, ABS, PC and other has water separation, for water separation 敏感, 而导致 in high temperature lower large degree reduce flow degree, water separation in melt in has increase box/case dilute function, has easy generate flash can can property. 3）因 add recycled material more 而令黏 degree decline generate flash. （四）, machine causes flash 1） machine true positive clamping force 不足. 2）模 sheet/plate balanced. 3） injection machine 四根格林柱 deformation non-uniform. 4） mold 安装不 balanced. currently inner injection molding enterprise in remove product flash/burrs 时,绝 large separation also is using/adopting most most small 刀人工修刮 process, and machine production 现代化 enterprise 显 格格不入,况且人工修刮 flash/burrs not only efficiency low, but also defect rate very high. meanwhile,现 in 人工工资 very high, make enterprise in cost upper very large (人员工资, tube/pipe use and other)! product flash/burrs already formed is injection molding enterprise development most large bottle 颈, Japan and carbon acid for injection molding industry difficult 而发明 代替人工修边 cold 冻修边 machine.国 inner in chemical industry has company will equipment to China,帮 very more injection molding enterprise (如:手 machine OEM factory and other and other) solution difficult issues!!!
