Sand casting

PROCESS AND PRODUCTION

Casting in sand moulds is one of the most popular technologies in production of semi-finished products due to its universality and low production costs.

It is used in production of individual and serial castings of varied weight and dimensions. The process consists of performing individual moulds made from mass with quartz sand grains (the sand is selected in line with the expected characteristics of the product) and filling them with metal of suitable properties. In most cases the mould includes a casting core intended to form the inner shape of the casting.

The method allow us to produce rough castings of varied shapes which usually undergo further mechanical working. With the latter process we are capable of achieving dimensional accuracy.

Omodelowanie odlewniczeh

W naszym zakładzie odlewniczym wykonujemy odlewy piaskowe w formach z różnego typu mas, w zależności od wagi i przeznaczenia odlewu. Przygotowujemy głównie formy dzielone wykorzystując modele wielokrotnego użycia i w niektórych przypadkach, głównie prototypach, także formy niedzielone  używając modeli jednorazowego użycia .

MOULDING

Proper moulding process is essential for the achievement of expected quality of castings. It is affected by the quality of the casting mass used, the process of its preparation, and then the technique of its proper dosing into boxes. The moulding shop in our aluminium foundry is equipped with modern casting mass mixing system and automatic mass dosing and thickening system. In some cases moulding takes place in self-curing and thermohardening casting masses.
