摘要
类似于气体辅助注塑 ,但用水代替气体来成型中空结构件的技术称为水辅注塑技术。该技术的最大优点在于通过水的冷却作用 ,可以使生产周期缩短 30 %～ 70 % (与气辅工艺比较 ) ,同时可以获得更小和更均匀的制品壁厚 ,材料的内部结构也更加均匀。对这种技术的原理、设备。
Water injection technique(WIT)is an injection molding technology,in that the hollow cavities are generated by injection of water instead of gas into the plastic melt.With WIT,production cycles can be shortened by 30 %～ 70 % compared with gas injection due to the better cooling effect of water.Furthermore,the thinner residual wall thickness,the more accurately centered cavity and the more homogenous microstructure can be achieved.The principles,injector technology, advantages and disadvantages,and potential application of WIT were introduced.
