Die-casting parts are uniform metal components that can be made in any size, finish, surface texture, or geometry. They are made from reusable molds, with their applications varying from aerospace to automotive. High-volume production projects are most suitable for die casting as the low-maintenance and simple tools make it possible to craft custom pieces in bulk quickly.
With different procedures, you must consider your requirements and find the most suitable material and technique to guarantee accurate parts and quick turnaround at a reasonable cost. Here are tips for choosing die-casting parts.
Know the options
Reputable die-casting specialists can create metal parts from materials such as magnesium, zinc, and aluminum. Like injection molding, the process uses a custom mold tool installed on a die-casting press to accommodate molten metal into the cavity. The components can be finished in different ways, including anodizing and powder coating.
Check your design
The success of the process can depend on your design. Manufacturers recommend checking it against a prospective manufacturing process to determine any changes when necessary. In die casting, you must consider several factors that can make and break the quality of your part.
Proper draft application is crucial to the process as it ensures consistency without surface defects or warping. The exact draft you require can depend on the tool or part design, but ask the manufacturer for professional advice.
Explore the materials
Material selection for die-casting parts can depend on the type and temperature of the metal. A higher temperature could mean serious wear and damage to the mold. Every aspect of the mold is subject to various conditions, impact, and wear, so ensure adequate hardness that suits your purpose.
When choosing die-casting parts, pay attention to factors like thermal conductivity, hardness, heat resistance, plasticity, strength, and resistance to molten metal damage and hot and cold fatigue. Moreover, consider small heat treatment deformation, hardenability, and tempering resistance.
