Gravity casting is a time-honored process that continues to hold significant potential for innovation. Addressing the need for versatility in customer foundries, Dratec has developed a modular machine concept designed for exceptional flexibility. This system enables quick changeovers for diverse casting applications and can be seamlessly scaled from basic to highly complex production. By integrating core pulls and additional clamping units, the base machine is perfectly equipped to manufacture even the most intricate castings with ease.

Compared with gravity casting, tilt casting offers the advantage of a significant reduction in the amount of recirculating material. This is achieved by utilizing the moulded part contour as a cast-in system and a reduced gating area. At the end of the filling process, the metal cast last collects in the gating area, which now serves as a feeder. The advantage of the modular design is also here the flexible attachment of core pulls with programmable travel speeds to adapt the machine to a wide range of requirements. The machines are completed by Dratec with external units for melt handling and part removal to form automatic casting cells.
