Kev Sau Duab Ntawv Twj Plastic Rau Injection Molding: Txhim kho rau PA66 Thermal Breaks

Kev tsim kho tshuab, txhawj xeeb rau tshuab extrusion die, yog qhov chaw uas kev kho tshuab siv ntau heev thiab kho mob kho tshuab, thiab yog qhov tseem ceeb heev rau kev tsim kho cov thermal break strips zoo. Tshuab extrusion die yog ib qhov chaw sib txig sib tov uas muaj zog siab, nyiaj cuab nyiaj tog uas ua phau ntawv tshuab tshwj tsis tau, tsim kho cov polyamide hlwb mus rau nws qhov chaw tshwj xeeb. Lub hlis ntim hauv, lossis manifold, yuav tsum tau tsim kho los ntawm kev siv software Computational Fluid Dynamics (CFD) kom paub meej tias cov polymer melt viscous no li cov dundoj li ntawm sab nraud ntawm lub tshuab die. Yog muaj qhov tsis sib xws hauv kev flow, yuav tshwm sim qhov khoom tsis zoo, xwm fab, xwm kab, lossis muaj qhov sib txawv tsis raug rau qhov thickness ntawm lub wall. Qhov ntev ntawm lub land length—the thaum kawg ntawm lub tshuab die—yuav tsum tau muab kho kom raug raws li qhov backpressure uas tseem ceeb rau kev ruaj khov cov melt thiab xaiv cov weld lines, kom paub meej tias muaj kev sib hloov zoo tshaj plaws thiab qhov surface finish zoo. Rau cov thermal break profiles tseem ceeb uas tuaj yeem muaj ntau qhov chaw lossis muaj qhov kev pab tshwj xeeb, qhov kev tsim kho tshuab die yuav tsum tseem ceeb dua. Thaum peb muab kev pab nrog Polywell, peb muaj kev paub ntau heev hauv kev tsim kho thiab tsim tshuab die. Peb tsim cov dies tsim nyog, tsis tu ncua, uas tseem ceeb qhov geometry txaus siab txog rau ntau million extrusion cycles, txhawm rau materials uas muaj glass filled, kom paub meej tias peb tus neeg siv khoom tuaj yeem tsim kho cov thermal break strips zoo, zoo tshaj plaws, thiab zoo tshaj plaws txhua hnub.
