Aluminium Gravity Die Casting

(Also Known As Permanent Mould Or Chill Casting)

At Skaigh Engineering we have been producing high-quality aluminium gravity die castings for a range of industries and customers since 1965. Gravity die casting is the process of pouring molten metal into a permanent cast-iron mould that is known as a die. Molten metal is poured into the die and gravity is used to fill the mould rather than pressure. Gravity die casting can be done using machines or manually and offers a higher casting rate than sand casting.

The casting process is essentially the same for both sand and gravity die casting with the main difference being the method by which the molten metal is poured into the die cavity. The casting process is as follows:

  • The die is heated and sprayed with a refractory coating

  • Once the die is coated it is then filled with molten metal

  • When the metal has solidified the die is opened to remove the cast parts

  • All scrap is then removed from the die including gate, runners, sprues and flash

Compared to sand casting, gravity die casting is able to produce higher quality castings with better accuracy, is stronger, more dimensionally consistent with a better surface finish. The faster casting rate is another reason to consider them but this is offset by the higher initial cost over sand patterns.

Since 1965 Skaigh Engineering has been providing our customers with high-quality gravity die casting of aluminium and zinc components. Over this time we have produced a wide range of complex castings in a wide variety of shapes and sizes.

We are continuing to invest in people and equipment and have recently replaced all of our furnaces with Morgan Mark IV/V High-Efficiency Recuperative Gas Fired Bale Out Furnaces which offer significant energy savings and environmentally friendly emissions. We are committed to reducing our impact on the environment while still providing our customers with the highest quality castings possible.

At Skaigh we offer customers both sand casting and aluminium gravity die casting which gives our customers a number of cost-effective options for their manufacturing needs.
