What is Gravity Die Casting?

Gravity Die Casting is a permanent wave mold molding process, where the mellow metallic element is poured from a vessel or ladle into the mold. The cast cavity fills with no power early than graveness, filling can be controlled by tilting the die. Undercuts, and cavities can be incorporated into the part shape with the use of sandpaper cores. This process gives a better surface polish than backbone shed a well as better mechanical properties, both ascribable to rapid hardening .
additionally, this action has a higher vomit rate than aluminum sandpaper cast, however, the metal molds are a higher price than sandpaper. Advantages of this process include the possibility of depleted gasoline porosity, and fine grain sizes can be achieved .
Compared to sand vomit, this procedure requires less coating and fettle and gravity die casting tends to produce a higher quality intersection. The Gravity die casting product method acting is by and large less price effective in the fabricate of tooling compared with sand cast.

Gravity Die Casting Process

Gravity die casting is often a manual process, with the molten alloy added with the use of a ladle. however, for some high volume applications it is besides potential to use an automated ladle to pour the mellow metallic element. The accelerate and the direction of the fill up can besides be controlled by tilting the die.

apart from the method by which the melt metallic is poured into the fail cavity, and the gravity die material, the project process is basically the like as sand frame. It involves four steps :

  1. The die is heated and then sprayed with a refractory coating, and closed. The coating both helps control the temperature of the die during manufacture and it also assists in the removal of the casting.
  2. Molten metal is then manually poured into the die, (although in some cases a machine can be used) and allowed to solidify.
  3. The die is then opened and the cast parts either removed by hand or in some cases ejector pins are used on the mechanised machines.
  4. Finally, the scrap, which includes the gate, runners, sprues and flash, is removed from the casting(s). The castings are then processed to remove sharp edges and excess material, then blast cleaned (if required) prior to dispatch to the customer.

Gravity die shed is a lifelike partner to sand draw, and allows us to offer the customer the most price effective road for casting fabrication .
