水辅技术介绍：HydrAIT technology introduced

英文-Water Assisted Injection Molding Technology，简称WAIM，是在气体辅助注射成型基础上发展起来的新技术，即用水来代替气体辅助熔体流动充模，最后利用气体或自重将水从制品空腔中排出的成型技术。

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世纪70年代初，就有人提出将流体注射到熔化聚合物中形成中空芯的概念，这就是后来的“水辅助注塑成型技术”（WIT）。但是这种技术由于气体辅助注射成型（GAIM）的出现和广泛应用而被搁置一旁。
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.
近年来，由于气体辅助注射成型技术使用中暴露出的一些不足，人们又转而对水辅助注射成型技术的研究工作发生兴趣。目前这一技术的研发工作进步很大，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.
水辅助注射成型技术的首次商业应用是德国SuloGmbH公司制造的全塑购物车。这个项目开始于1998年，它用到了舒尔曼公司的PP材料和PME公司水辅助注射成型技术，来成型一个有三条直径为20-60mm，长为800-1500mm水道的制品。这个PP材料的购物车原来用气体辅助注射成型周期需要280s，而用水辅助注射成型只要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.
