         extrusion machine export pressure various factors effect/influence in relatively large 波动, can effect/influence products dimensions degree

         if in extrusion machine export and between add 装一台 melt 泵, can use stability extrusion machine export pressure 波动, make property extrusion formed is can can, from improve/increase plastics products dimensions degree, in mono time inner improve/increase extrusion machine output/production volume. melt is types positive 位移输送 equipment, high degree gears and 容积式 structure design, make stability extrusion formed is can can, in 化纤, pelletizing, plastics film, sheet/slice 材, sheet/plate 材, type 材, pipe/tube, electrical cable, wire drawing, composite/compounding extrusion and other production upper to application, comparison good 效果:

        1. can achieve stability extrusion, improve/increase extrusion products dimensions degree, reduce waste product rate. in extrusion process in, material material add material amount non-uniform, machine and machine temperature degree 波动, screw speed and other phenomenon is difficult 以避免. use melt gears can remove add material system add material 误差, can large degree decrease low upper process 传递 波动, fast speed stability as 状态, improve/increase extrusion products dimensions degree, reduce waste product rate.

        2. improve/increase output/production volume, reduce can consumption, achieve low temperature extrusion, long machine lifespan. due to extrusion machine polymer melt 泵, extrusion machine decrease pressure function to gears upper formed, extrusion machine can in low pressure low temperature lower as, amount large large decrease/reduce, output/production volume improve/increase. gears ratio extrusion machine more easy has 效 建立 machine pressure, can reduce extrusion machine back pressure, make screw 承受 轴 toward force decline, long use lifespan.

        3. tool has property extrusion features, upper, lower equipment 协调工 as. due to gears 泵漏流 amount relatively less, 泵 输送 can force and speed basic formed property 关系, gears speed rear, its amount can 确切 知道, due to can upper, lower equipment and gears 泵同步 工 as speed degree, utilizing gears 泵入口, export 处采集 pressure, temperature degree and other 信息资 material, achieve extrusion process full in 线监测 and control.
