Molding | Permocast | Aluminum Casting | Texas


Permanent Mold is a great alternative to Die or Sand Casting, providing you, the customer, with high
quality castings at reasonable tooling and part prices. Permocast is dedicated to producing
quality castings, delivered on time at a fair price.


The Permanent Mold Process

The tilt of the machine pours molten aluminum into the die. The pour is hydraulically controlled to be approximately the same every time. Turbulence caused by an inconsistent pouring rate is controlled. After a preset chilling time, the mold is automatically opened and the part is ejected by a plate activated ejector system. Through strict control of each production variable, human error and rejects are minimized, resulting in high repeatability and maximim efficiency.

Advantages of Permanent Mold

  • 1

    Affordable tooling prices make it cost effective to produce in low, medium, or high volume.

  • 2

    Shell cores can be used to cast complex shapes, thereby reducing or eliminating machining costs.

  • 3

    Permanent mold castings are pressure tight with low porosity, fine grain structure and superior strength.

  • 4

    Permanent mold castings are dimensionally stable. Superior as-cast properties frequently eliminate requirements for heat treating.

  • 5

    Fine as-cast finish can eliminate some costly pre-paint preparations.
