Permanent Mold Casting

Martinrea Honsel has the capability to provide three different methods of the permanent mold process: (i) the gravity PMC, (ii) the gravity tilt PMC and (iii) the low pressure PMC. In the comparison with the gravity process in the gravity tilt process, the die is tilted towards the side of the pouring opening and then slowly moved back into the upright position as the pouring progresses.

In the low-pressure process, the molten metal is subjected to pneumatic pressure in the casting furnace and enters the die opposite the force of gravity through a rise pipe. The advantages of the low pressure PMC are good filling-ability for thin-walled and large area parts and hollow and pressure tight structures for air or fluid containment.
