Die Casting For Mass Production

A highly efficient and cost effective process that delivers on quantity and quality

Die casting is often used in mass production of zinc, magnesium or aluminum parts. It is a very cost-effective production method that can achieve a high production rate, while still offer great accuracy and consistency.

As die casting and engineering specialists, the Omnidex Casting Team offers a full range of die casting services that exceeds the capabilities of a typical foundry. From die making to production engineering and QC, we can have the entire production line set up for you.

Close connections with the top-performing die casting factories

We have been working with some of the best die casting factories for many years. These factories can produce top quality products with highly accurate dimensions and tolerances. Also, you are not limited to the capacity of just one manufacturer, giving you more choice on materials and casting methods.

Advanced simulations and engineering support

We use the very latest software to simulate molten metal flow during the Die Casting process so that we can highlight feed points and identify areas where improvements can be made. Our casting designs always take the metal flow path and cooling shrinkage into consideration. Overflow wells, venting holes and cooling channels can be added to the designs if issues are found after simulation runs to improve the casting results.

Expert in die design and making

The die is the most important component in the process. The die must facilitate molten metal flow to fill up the cavities in the die. A draft angle is also necessary for easy removal of the solidified casting. More complex parts may have undercuts in the design, which require more die pieces. Our dies are typically made out of high-grade tool steel for optimal durability and cost-effectiveness, but we can also provide dies made of other special materials and alloys if necessary.

3 types of Die Casting methods

Cold-Chamber Conventional Die Casting

This process involves heating metal in a separate furnace, then transferring the molten metal into the casting machine. It is used for metals with a higher melting point, such as aluminium, magnesium and copper.

Hot-Chamber Conventional Die Casting

Instead of using a separate furnace, metal is heated inside the casting machine. The injection mechanism involves a goose-neck machine placed inside a crucible, which can heat the metal to melting point and inject it into the die. It is typically used for metals with lower melting points such as zinc alloys.

Multi-Slide Hot-Chamber Die Casting:

Multi-slide die casing uses tools with 4 perpendicular slides (in some cases up to 6 slides at angles other than 90°) to produce more complex and accurate castings. This process is used to produce small zinc alloy components at a rapid production rate.
