The dimensional tolerance die casting is one of the important indexes of casting quality. They are based not only the alloys used, but also the length,size, shape and location of each feature. So, to select the right die cast, we need to learn about the tolerance standards. Here we list the NADCA Dimensional Tolerance Standards For Die Cast. We also discuss how do the tolerances measure up to each other.
At Die-casting mould, we specialize in aluminum and zinc die casting, which are the two materials we’ll cover in this article.
The quality of die casting parts is affected by the selected raw materials, as one of the most commonly used materials, aluminum accounts for a large proportion in the metal cast products, and aluminum die casting enables a higher manufacturing rate than many other metal alloys. This technique also tends to be less costly. It yields lightweight but durable parts ready for any application.

Zinc is the fourth most popular materials in the metalworking industry that are shaped into die cast products. Many manufacturing experts consider zinc the easiest and least expensive metal to cast with because of its low melting point. It offers a range of benefits include maximum strength and hardness, corrosion resistance and higher dimensional stability than other metals.

Tolerances are used in more than die casting, these measurements come up in other production processes like sand casting, investment casting and machining. When you need a part with extreme precision, it’s often best to choose CNC machining. Like die casting, sand casting can adapt to complex designs and is compatible with a range of metal alloys. However, compared with die casting, this method has many disadvantages. It requires you to make a new mold every time you create a part, which can be time-consuming and expensive. High-precision work is possible with this method, but because it uses loose material instead of metal, its precision is not as good as that of mold. When dealing with die castings, you will also get higher tolerances.
