Die casting lets you make high-volume metal parts from select materials, such as magnesium, zinc, or aluminum. Like injection molding, the process involves a custom mold installed on a die-casting press before injecting molten metal into it. The right manufacturing partner will ensure cost-effective and reliable die-casting services that will deliver your parts with precision, with a range of finishing and post-process machining options. However, there are things you must consider before signing up for the service.
Consider the size and geometry of the part, the quantities you require, and other factors like the finish, strength, and thermal characteristics. You must also look into the speed or timing of your project and your budget and make sure the service provider can meet them.
Look into your manufacturing or production requirements. Die casting services is ideal for low to mid-volume metal part production and building complex and production metal parts. Moreover, check your design against your preferred manufacturing process to determine if you need to make changes
The process and machinery
Manufacturers refer to the clamp force tonnage available when classifying cold chamber and hot chamber die-casting machines. Machinery can accommodate 400 to 4,000 tons, but no matter the size, the purpose is the same, and that is to cast the part with injected molten metal.
Talk to the company offering die-casting services to learn about machine performance and clamping force. They can tell you about dimensional constraints, such as the platen area, die opening stroke length, and shot volume capacity.
Types of dies
Die makers offer multiple and single cavities, a combination of both, and unit dies. They make casting tools from alloy tool steels, such as zinc, magnesium, and aluminum.
Your design versus the die-casting process
There are many things to consider to get a high-quality part. For instance, you should ensure a proper draft for consistency and to avoid surface defects and warping. The amount of draft depends on the tool design and part, but be sure to speak with the provider of die-casting services for advice.
