The moulding machine includes a moulding chamber having at least one chamber end wall provided with a pattern plate adapted to form a pattern in a mould part and associated with a reference pattern block positioned in fixed relationship to a pattern of said pattern plate and adapted to form a reference pattern in an external face of a mould part. A detection system detects the position of a pattern face of the reference pattern of the sand mould part. A transverse and/or a rotational compaction position of a pattern plate is adjustable by means of at least one actuator. Said actuators are controlled by means of a control system on the basis of successive position detections performed by the detection system of pattern faces of reference patterns of compacted sand mould parts traveling along said path of travel.

Disclosed is a lost-wax method of casting a product, having steps of: attaching temperature control elements to a wax assembly; encasing the wax assembly and the temperature control elements in a ceramic mold; removing the wax assembly from the ceramic mold; filling the ceramic mold with molten material to form a cast part within the ceramic mold; and separating the ceramic mold and the cast part from each other.
