Casting flask is also called moulding flask, sand box or moulding box. It is an indispensable tool in the production of sand castings. At the same time, it also plays an important role in the casting process. A suitable sand box can improve the quality of casting and reduce the consumption of molding sand, thereby reducing production costs.
Casting flasks are usually made by welding steel plates. But it can also be made by sand casting process. In other words, the sand box itself can also be a sand casting. For the automatic molding line, the casting flask has a fixed size. Taking the FBO 3 automatic molding line as an example, the size of the flask should be 508 * 610mm.
If the iron foundry does not have a suitable casting flask, then they will have to make some casting flasks for production. There are many types and sizes of sandboxes. The small flask is suitable for the production of small metal castings, and the large flask is suitable for large castings. Their shapes include circles and squares. Sometimes, some reinforcing ribs are welded inside to fix the molding sand. During the casting process, all designs need to be considered to suit production. However, the flask of the automatic molding line cannot be changed. Only packaging boxes used for manual molding and resin sand molding processes can be used.
Generally, unless you want the iron foundry to speed up production, the purchaser of castings does not have to bear the cost of manufacturing the sand box. More flasks can greatly increase productivity.
