FAQ
Q: Yuav ua li cas rov qab - tswj kev tswj xyuas qhov hnyav npaum li cas?
A: Rov qab siab muab kev tiv thaiv tsis tu ncua rau cov ntsia hlau thaum rov qab los. Qhov no mechanical quab yuam compresses resin ua ntej ntawm lub hau ntsia hlau, venting cua ntxiab thiab standardizing cov ntaub ntawv ceev. Consistent melt density yields uniform volumetric filling across successive cycles.
Q: Dab tsi rov qab - qhov siab ntau yog haum rau cov txheej txheem polymers?
A: Kev khiav hauj lwm rov qab siab khiav ntawm 5 bar mus rau 30 bar rau cov khoom resins thiab 30 bar rau 100 bar rau engineering polymers xws li PC, PA66, los yog PBT. Kev txhawb nqa rov qab los txhim kho cov khoom sib xyaw, uas yuav tsum sib npaug nrog cov ntsia hlau ceev kom txo cov thermal shear.
Q: Lub tshuab no puas tuaj yeem ua cov iav - fiber ntau - rov ua cov resins yam tsis muaj ntsia hlau hnav?
A: Yog. Lub zog rov qab ruaj khov kho plasticizing stability yam tsis tas yuav tsum tau ua kom nrawm nrawm. Rau abrasive compounds, bimetallic chim thiab coated screws tiv thaiv mechanical clearances tiv thaiv ntev - lub sij hawm hnav.
Q: Dab tsi ua rau kev hloov pauv ntawm kev txhaj tshuaj mus rau theem plasticizing?
A: Tus maub los pib ntsia hlau rov qab thaum lub sijhawm tuav xaus thiab lub sijhawm txias pib. Screw rotation pib thaum lub proportional valve tswj cov roj tso tawm tom qab txhaj tshuaj piston, tswj lub hom phiaj rov qab siab kom txog thaum lub hau ntswj mus txog nws qhov ntsuas qhov nres.
Q: Yuav ua li cas kaw - voj voog tswj tiv thaiv kev txhaj tshuaj luv?
A: Kaw - voj tswj lem hydraulic Circuit Court siab thiab ntsia hlau txoj hauj lwm tsis tu ncua. Thaum resin viscosity los yog chim kub hloov, tus maub los kho lub valve chaw nyob rau hauv milliseconds kom ua raws li qhov programmed profile, tiv thaiv kev hloov pauv.
