| Advantages | the castings have excellent dimensional accuracy. |
| Shortcoming | ² The main drawback of die casting is its high cost.
² The equipment for die casting, as well as the molds and related components, are relatively expensive compared to other casting methods. ² Therefore, it is more economical to produce a large quantity of parts when manufacturing die castings. |
| Step | Specification |
| Mold Preparation | ² During the preparation process, a lubricant needs to be sprayed into the mold cavity.
² The lubricant not only helps control the temperature of the mold but also facilitates the removal of the castings. |
| Filling and Injection | ² After closing the mold, high pressure is used to inject the molten metal into the mold.
² The pressure range is approximately between 10 and 175 megapascals. ² Once the molten metal is fully filled, the pressure will remain constant until the casting solidifies. |
| Sand removal | ² The pusher rod removes all the castings and separates the residues, including the mold opening, risers, gates, and burrs.
² This process is usually accomplished by pressing the castings through a specially designed finishing mold; ² Other methods include sawing and grinding. |
| Post-processing | ² During the production process of die-cast parts, problems such as bubbles and burrs may occur,
² And there may also be residual mold sand and oxide scale. ² Therefore, after the die-cast parts are manufactured, post-processing work needs to be carried out, including grinding, polishing, spraying, electroplating and other processes. ² The purpose is to make the surface of the die-cast parts more beautiful, while improving their corrosion resistance and mechanical properties. |
