中英对照，可直接用于产品样本、外贸手册

一、主要适用场景 Main Application Scenarios

1.注塑成型行业（*主流）Injection Molding

中文 机边直接安装在注塑机料斗上方；新料+水口回料+色母+功能母粒多组分配比；家电外壳、汽车内饰件、日用品、塑胶配件；频繁切换多套产品配方，稳定产品色差与克重，降低**率；也可接入中央供料系统，多台注塑机集中配料。

English Machine‑side installation above injection machine throat. Proportion virgin pellet, sprues/regrind, color masterbatch and functional additives. For home‑appliance housings, automotive interior parts, daily plastic goods. Frequent recipe change‑over, stabilize color & part weight, reduce reject rate. Can integrate with central material‑handling system for centralized batching for multiple injection machines。

2.普通挤出工艺 General Extrusion

中文 管材、型材、板材、普通吹膜、淋膜；rPET回收料改性；PLA/PBAT可降解塑料配料；3D打印耗材挤出；适合中等产能、允许间歇批次工作的挤出线。

English Pipe, profile, sheet, general blow‑film, lamination film; rPET recycling compounding; PLA/PBAT biodegradable plastic batching; 3D‑printing filament extrusion. Suitable for medium‑output extrusion lines allowing intermittent batch operation。

3.塑料回收再生 Plastic Recycling

中文 回收颗粒、破碎回料与新料精准配比；回收料批次品质波动大，重量计量抵消密度变化，保证每一批次配比一致。

English Accurate blending of regrind/recycled pellets with virgin resin. Gravimetric measurement offsets density fluctuation of recycled materials to guarantee consistent batch ratio。

4.改性与特种颗粒 Compounding & Special Pellets

中文 通用改性颗粒、TPE弹性体、电缆料；多配方小批量换产；颗粒类阻燃、增韧助剂配比。

提示：微量添加＜0.5%不建议单用GIW，建议搭配独立失重色母机。

English General‑purpose compound, TPE elastomer, cable‑grade compounds. Small‑batch production with frequent recipe switching. Dosing of pellet‑type flame retardant & toughening additives.

Note: Not recommended for additive ratio below 0.5%, better cooperate with separate loss‑in‑weight feeder。

5.无纺布、化纤颗粒配料 Non‑woven & Chemical Fiber

中文 无纺布生产线颗粒配料；化纤粒子共混；流动性良好颗粒物料。

English Pellet batching for non‑woven production line; blending of chemical‑fiber pellets, for free‑flowing pellet materials。

二、适合物料 Suitable Materials

中文：流动性良好塑料颗粒：PP、PE、ABS、PC、TPU、PET、rPET、PLA、PBAT、TPE、各类色母粒、颗粒状助剂、破碎回料。

English: Free‑flowing plastic pellets: PP, PE, ABS, PC, TPU, PET, rPET, PLA, PBAT, TPE, color masterbatch, pellet‑form additives, crushed regrind.

三、不适合场景 Not‑Recommended Applications

中文

1. 高速24h连续挤出（流延膜、大产能造粒线）：优先选用失重式LIW喂料机；
2. 超细粉体、高粉尘物料，易挂壁搭桥，影响称重精度；
3. 极低比例微量添加（＜0.5%），传感器量程造成相对误差放大。

English

1. High‑speed 24‑hour continuous extrusion (cast‑film, high‑capacity compounding line): loss‑in‑weight feeder is preferred.
2. Ultra‑fine powder, high‑dust material: easy bridging & material hanging, deteriorate weighing accuracy.
3. Micro‑dosing below 0.5%: relative error amplified by load‑cell range。

简短版英文（样本摘要）

Applications of Gravimetric Batch Blender(GIW) Widely used in injection molding, general extrusion (pipe, sheet, blow‑film), plastic recycling, biodegradable‑plastic processing, 3D‑printing filament and non‑woven industries. It handles virgin resin, regrind, color masterbatch and pellet‑form additives. It works in batch mode, ideal for medium‑capacity lines with frequent recipe change‑over. Not suitable for high‑speed continuous extrusion and ultra‑fine powder materials.
