Custom metal die-cast parts refer to metal parts that are produced through the die casting process and are custom-made according to the specific requirements of a customer. In die casting, molten metal is forced into a mold cavity under high pressure. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Once the metal has solidified, the dies are separated and the cast part is ejected .

A die-casting die is a specialized tool used in the process of die-casting to manufacture high-volume, low-cost metal parts with tight tolerances. The die-casting die is made up of several parts, which include:

1. Die cavity: This is the part of the die that defines the shape and size of the final product. The molten metal is injected into the die cavity to form the desired shape.
2. Sprue: This is the channel through which the molten metal is injected into the die cavity. The sprue is typically located at the bottom of the die cavity.
3. Runner: The runner is a channel that connects the sprue to the different parts of the die cavity. It helps to distribute the molten metal evenly throughout the die cavity.
4. Gate: The gate is the point where the molten metal enters the die cavity. It is located at the end of the runner and is designed to control the flow of metal into the cavity.
5. Ejector pins: These are the components that help to eject the finished part from the die cavity once it has cooled and solidified. The ejector pins are typically located on the side of the die and are activated by a mechanism that pushes them against the finished part.
6. Cooling channels: These are channels that are built into the die to help regulate the temperature of the die during the casting process. The cooling channels help to prevent the die from overheating and warping, which can result in defects in the finished product.
7. Die halves: The die halves are the two main parts of the die that are bolted together to form the complete die. The die halves typically contain the die cavity, sprue, runner, gate, ejector pins, and cooling channels.

Die casting is a metal casting process that involves forcing molten metal under high pressure into a mold cavity, known as a die, which is typically made of steel. The molten metal is injected into the die cavity at high speed and pressure, and then solidifies rapidly to form a complex, three-dimensional shape.

The die casting process typically involves the following steps:

1. Mold preparation: The die casting machine operator prepares the mold by cleaning it, applying a lubricant, and closing the two halves of the mold.
2. Molten metal injection: The molten metal is melted in a furnace and then injected into the die cavity at high speed and pressure using a hydraulic piston.
3. Cooling and solidification: The molten metal cools and solidifies rapidly inside the die cavity, taking on the shape of the mold.
4. Ejection: Once the metal has solidified, the die halves are opened and the finished part is ejected from the die cavity using ejector pins.
5. Trimming and finishing: The finished part may require additional trimming, machining, or finishing operations to remove any excess material or improve its surface finish.

Die casting is used to produce a wide variety of parts with high dimensional accuracy, excellent surface finish, and tight tolerances. It is commonly used to manufacture parts for the automotive, aerospace, electronics, and consumer goods industries, among others.

The time it takes to complete a custom die casting project can vary widely depending on several factors such as the complexity of the part, the size of the production run, the level of design work required, and the capabilities of the chosen die casting company. Generally, the lead time for custom die casting projects can range from a few weeks to several months.

Here is a breakdown of the typical lead times for custom die casting projects:

1. Tooling design and fabrication: This is the process of designing and manufacturing the die casting tooling or molds required to produce the custom part. Depending on the complexity of the part and the level of design work required, this process can take anywhere from a few weeks to several months.
2. Sample production and approval: Once the tooling is completed, the die casting company will produce a small batch of sample parts for approval by the customer. This process can take several days to a few weeks, depending on the complexity of the part and the availability of the necessary materials.
3. Production run: After the samples are approved, the die casting company will begin the full-scale production run. The length of the production run will depend on the size of the order, but can take several weeks or even months to complete.

It’s important to note that custom die casting is a complex process, and lead times can be impacted by a range of factors, such as the availability of raw materials, the capacity of the die casting company, and unforeseen manufacturing issues. It’s always a good idea to work closely with the chosen die casting company to understand their specific lead times and to plan accordingly.
