         gas injection molding （GAIM）

         molding principle:

         gas molding (GAIM) is in plastics to type 腔适当 时候(90%~99%)注入 high pressure inert property gas 体, gas 体推动 melt plastics 继续充填满 type 腔, use gas holding pressure plastics holding pressure process types new injection molding technology.

         features:

         decrease/reduce residual stress, drop low warpage issues;

        消 remove 凹陷痕迹;

         reduce clamping force;

         decrease/reduce runner long degree;

        节省材 material;

         shrink short production cycle time;

        延 long mold lifespan;

         reduce injection molding machine machine loss consumption;

        应 used for thick degree large formed product.

        GAIM can used for production tube/pipe and rod products, sheet/plate products and thick thin complex products.

         water injection molding (WAIM)

         molding principle:

         water injection molding (WAIM) is in GAIM upper development 起 一 types injection molding technology, its principle and process and GAIM similar. WAIM use water 代替GAIM N2做 is 排空, melt and pressure 介质.

         features: and GAIM versus ratio,WAIM tool has less advantages

         water hot rate and hot amount ratio N2 large more,故 products cooling time short, can shrink short molding cycle;

         water ratio N2 more 便宜,且 can ring use;

         water tool has can pressure shrink property,不容 easy 出现手指效应, products thick relatively uniform;

         gas easy or solvent melt make products inner coarse 糙, its in inner generate bubbles,而 water easy or solvent melt,故 can made inner light slip products.
