Deoarece cele dou\u0103 procese influen\u021beaz\u0103 diferit propriet\u0103\u021bile materialului \u0219i geometria, schimbarea necesit\u0103 de obicei reproiectarea complet\u0103 a piesei.<\/p>\n<p class=\"ds-markdown-paragraph\">De exemplu, un suport forjat masiv ar putea necesita goluri \u0219i nervuri de ranforsare pentru a putea fi turnat sub presiune, \u00een timp ce o carcas\u0103 turnat\u0103 ar putea necesita simplificare \u0219i \u00eengro\u0219are pentru a rezista solicit\u0103rilor forj\u0103rii.<\/p>\n<h3 class=\"ds-markdown-paragraph\">Exist\u0103 limite de dimensiune pentru aceste procese?<\/h3>\n<p class=\"ds-markdown-paragraph\">Da, fiecare proces are limite practice de dimensiune. Turnarea sub presiune este limitat\u0103, \u00een general, de dimensiunea injec\u021biei \u0219i for\u021ba de \u00eenchidere a ma\u0219inii, fiind potrivit\u0103 pentru piese mici \u0219i medii, precum carcasele \u0219i suporturile. Forjarea poate produce componente masive, precum elice de nave sau c\u00e2rlige mari de macara, dar este limitat\u0103 de capacitatea presei \u0219i de posibilitatea \u00eenc\u0103lzirii uniforme a lingourilor mari de metal.<\/p>\n<h3 class=\"ds-markdown-paragraph\">Cum difer\u0103 costul final al unei piese turnate brute fa\u021b\u0103 de o pies\u0103 forjat\u0103 brut\u0103, dac\u0103 necesit\u0103 volume diferite de lucr\u0103ri secundare?<\/h3>\n<p class=\"ds-markdown-paragraph\">Structura costului total difer\u0103. Turnarea sub presiune are de obicei un cost ini\u021bial mai mare pe kilogram de material, dar un cost mai mic pentru finisarea secundar\u0103, deoarece produce forme apropiate de cele finale. Forjarea poate avea un cost mai mic al materiei prime, dar costuri secundare mai mari (prelucrare mecanic\u0103 \u0219i finisare), deoarece de\u0219i forma ini\u021bial\u0103 poate fi apropiat\u0103 de cea final\u0103, sunt necesare lucr\u0103ri de precizie suplimentare pentru toleran\u021be stricte. Op\u021biunea \u201emai ieftin\u0103\u201d depinde de costurile materialului \u0219i manoperei \u00een compara\u021bie cu timpul de prelucrare \u0219i amortizarea sculelor.<\/p>\n<h3 class=\"ds-markdown-paragraph\">Aceste procese influen\u021beaz\u0103 comportamentul piesei la tratament termic sau acoperire de suprafa\u021b\u0103?<\/h3>\n<p class=\"ds-markdown-paragraph\">Da. Datorit\u0103 structurii granulare dense \u0219i orientate a pieselor forjate, acestea r\u0103spund de obicei uniform la tratamente termice precum c\u0103lirea \u0219i revenirea, care le sporesc \u0219i mai mult rezisten\u021ba. Piesele turnate sub presiune pot avea probleme la anumite tratamente termice din cauza porozit\u0103\u021bii interne (pot forma b\u0103\u0219ici) \u0219i pot necesita etan\u0219are specializat\u0103 (precum impregnarea \u00een vid) \u00eenainte de aplicarea unor acoperiri, cum ar fi vopsirea \u00een c\u00e2mp electrostatic sau placarea cu crom, pentru a preveni degazarea.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Alegerea dintre turnarea sub presiune \u0219i forjare influen\u021beaz\u0103 rezisten\u021ba, costul \u0219i performan\u021ba unei piese metalice.
