Foundries have a variety of classification methods: according to the different metal materials used, is divided into cast steel, cast iron, cast copper, cast aluminum, cast magnesium, cast zinc, cast titanium and so on. And each type of foundries can be further divided into different types according to its chemical composition or metallurgical organization. Such as cast iron can be divided into gray cast iron, ductile iron, creep cast iron, malleable cast iron, alloy cast iron, etc.; according to the foundry of different molding methods, can be divided into ordinary sand foundry, metal foundry, die foundry, centrifugal foundry, continuous pouring, mold foundry, ceramic foundry, electro-slag remelting foundry, bimetallic foundry, etc.. Among them, the most common sand foundry applications, accounting for about 80% of all foundry production. And aluminum, magnesium, zinc and other non-ferrous metal foundries, mostly die foundries.

Funderija produzzjoni, to control the quality of foundries and inspection. First of all, to develop from raw materials, auxiliary materials to each specific product control and inspection of the process code and technical conditions. Each process is in strict accordance with the code of technology and technical conditions for the code of technology and technical conditions for control and inspection. Fl-aħħarnett, the finished foundries for quality inspection. to inspection. quality inspection. To be equipped with reasonable ittestjar metodi u xieraq ittestjar persunal. Ġeneralment fuq id-dehra ta ' il- funderija kwalità , can be meta mqabbla ma' il - kampjun blokk biex jiddetermina il - wiċċ ħruxija ta ' il- funderija ; il-wiċċ ta' il-multa xquq jista ' ikun kulur metodu, manjetiku partiċella metodu ta' spezzjoni. Interna kwalità ta ' funderiji, disponibbli awdjo, ultrasound, eddy kurrenti , X-ray u - ray metodi biex iċċekkja u imħallef.
