水輔技術(shù)介紹：HydrAIT technology introduced

英文-Water Assisted Injection Molding Technology，簡稱WAIM，是在氣體輔助注射成型基礎(chǔ)上發(fā)展起來的新技術(shù)，即用水來代替氣體輔助熔體流動充模，最后利用氣體或自重將水從制品空腔中排出的成型技術(shù)。

English - Water Assisted Injection Molding Technology, referred to as "WAIM, is developed on the basis of    gas-assisted Injection Molding Technology, namely Water instead of gas Assisted melt flow Molding, finally use gas or Water weight from products to remove the Molding Technology of the cavity.
早在20世紀70年代初，就有人提出將流體注射到熔化聚合物中形成中空芯的概念，這就是后來的“水輔助注塑成型技術(shù)”（WIT）。但是這種技術(shù)由于氣體輔助注射成型（GAIM）的出現(xiàn)和廣泛應用而被擱置一旁。
As early as the early 1970 s, some will be formed in the fluid injected into the melt polymer in the concept of tubular, which is then "water assisted injection molding technology (WIT).But this technology due to the presence of the gas assisted injection molding (GAIM) have been set aside and widely used.
近年來，由于氣體輔助注射成型技術(shù)使用中暴露出的一些不足，人們又轉(zhuǎn)而對水輔助注射成型技術(shù)的研究工作發(fā)生興趣。目前這一技術(shù)的研發(fā)工作進步很大，并已得到商用。
In recent years, because of gas assisted injection molding technology used in the exposed some shortcomings, people turn to take an interest in the research of water assisted injection molding technology.At present the research of the technology progress is very big, and has set up a commercial.
水輔助注射成型技術(shù)的首次商業(yè)應用是德國SuloGmbH公司制造的全塑購物車。這個項目開始于1998年，它用到了舒爾曼公司的PP材料和PME公司水輔助注射成型技術(shù)，來成型一個有三條直徑為20-60mm，長為800-1500mm水道的制品。這個PP材料的購物車原來用氣體輔助注射成型周期需要280s，而用水輔助注射成型只要68秒。
Water assisted injection molding technology of the first commercial application was made in German SuloGmbH company all plastic shopping cart.This project began in 1998, it USES shulman PP material and PME company water assisted injection molding technology, to shape a has three of 20 to 60 mm diameter, length of 800-1500 - mm channel of the products.The PP material shopping cart with original gas assisted injection molding cycle need 280 s, and as long as water injection molding in 68 seconds.
