Mold Coatings for Release & Protection

Permanent mold coating is one of the operational parameters of the casting process that is often overlooked or misunderstood.

Coatings are necessary to provide 3 basic functions

  1. Act as a protective barrier between the mold and the casting to prevent mold erosion and wear
  2. Some degree of control over the solidification rate and direction
  3. Ensure the cast metal can be easily released from the mold as a barrier between the mold and the casting

There are different types of coatings, including release coatings that help with the mold release (often containing graphite for its lubricative properties) and insulative coatings that control heat flow (with varying refractory materials like vermiculite, bentonite, or graphite affecting their properties).

Read the full article for surface preparation, methods of application, and conditions under which coatings should be applied.

Recognized for their advanced tilt pouring capabilities, these machines minimize turbulence, ensuring consistent molten metal flow into the die cavity. The result?

  • Faster cycle times
  • Efficient metal usage
  • Enhanced aluminum casting quality

With aluminum castings presenting superior hardness, pressure characteristics, and a tight dendrite structure, we offer an edge over other casting methods. Our process facilitates easy integrations, such as sand cores or cast-in ferrous inserts. Having been at the forefront of permanent mold casting technology since 1959, our machines are an amalgamation of decades of experience and cutting-edge technology, driving unparalleled profits and production for businesses.

Vac-U-Check
Hydrogen is our friend or foe. Depending on the type of casting you produce, hydrogen absorption by molten aluminum can be helpful or harmful.

With the HALL Vac-U-Check you are assured a quick, simple, economical, and accurate method of monitoring the hydrogen level in your melt.

A vacuum solidified sample exaggerates the hole size, making the analysis of gas in the sample easy to determine by visual methods or by using the specific gravity formula.
