Metal casting has been a cornerstone of metalworking for art and industrial projects since 3200 BCE, and it has evolved to produce a wide array of objects such as weapons, jewelry, and components for the automotive, electronics, aerospace, machinery, and medical industries. This method is ideal for creating both simple and intricate metal parts more efficiently and cost-effectively than other techniques, including CNC prototyping.
However, for certain projects, blending CNC machining with metal casting delivers the best of both worlds: speed and precision. If you're deciding which method suits your project best, consult with an experienced service providerwho can assist you in choosing the appropriate materials and metal casting techniques.
Which metal casting method and material should you choose?
Your choice depends on factors like your part’s design, shape, size, strength, purpose, and quantity, as well as the desired surface finish, cost, and project timeline. Regardless of your design, take the time to check it against your preferred manufacturing process to determine if you need to make any changes. Here are some of the popular metal casting services:
Hot chamber or gooseneck die casting: Hot chamber is the most commonly used die casting process where a chamber of an injection system is immersed in molten metal, while a gooseneck metal feeder delivers the metal into the cavity.Cold chamber die casting: Where machine corrosion is a concern, cold chamber die casting can be the alternative to the hot chamber method because it doesn’t immerse the injection system into molten material.Sand casting: A tried-and-true metal casting method that uses hardened sand to make complex parts.
Selecting the best materials
Whether CNC prototyping or metal casting, material selection ultimately depends on what you’re making, the quantity, and the function. Pressure die casting can deliver high-quality parts in high volumes using materials like magnesium, zinc, and aluminum. These materials are versatile for making prototypes and end-use parts. Additionally, consider the environmental factors that can impact your design, the material properties, and the part’s life cycle.
