Introduction to systemic analysis of die-casting of molten metals
U proteklih pola stoljeÄa broj postupaka koji su osnovni uzor tlaÄno lijevanje metala i injekcijsko preÅ”anje plastomera porasta je na viÅ”e od 260. To zahtijeva poopÄavanje i razvoj opÄeg modela kojim bi bili obuhvaÄene sve postojeÄe inaÄice navedenih postupaka. Na temelju provedenih istraživanja ustanovljeno je da su tlaÄno lijevanje i injekcijsko preÅ”anje, prema funkcijama koje trebaju ispuniti u osnovi isti postupci s razliÄitim materijalima i parametrima praoblikovanja. U prvom Älanku analiziran je povijesni razvoj navedenih postupaka i utjecaj uvoÄenja novih inaÄica. To je dovelo do potrebe precizirane terminologije, pa se sada preciznije radi o tlaÄnom lijevanju metalnih taljevina i injekcijskom preÅ”anju elastomernih taljevina. Na temelju provedenih istraživanja navedeni su faktori koji utjeÄu na sustavnosni pristup tlaÄnom lijevanju metalnih taljevina. U drugom dijelu opisat Äe se sustavnosna analiza tlaÄnog lijevanja metalnih taljevina.In the past half century, the number of procedures that are basic models of metal die casting and injection molding of thermoplastics raised to more than 260. This requires a generalization and development of a general model that would cover all existing versions of these operations. On the basis of research it was found that the die casting and injection molding, according to the functions to be fulfilled, are essentially the same procedures with different materials and primary shaping parameters. The first article analyzes the historical development of the above procedures and the impact of the introduction of the new versions. This has led to the need for refined terminology, so now the terms are more precisely defined as die casting of metal melts and injection molding of thermoplastic melts. On the basis of research are listed factors affecting systemic approach of die casting of metal melts. The second part will describe the systemic analysis of die casting of metal melts
