Die Casting Capabilities
Die casting is a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. The die casting process involves the use of a furnace, metal, die casting machine, and die. The metal, typically a non-ferrous alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine. There are two main types of die casting machines - hot chamber machines (used for alloys with low melting temperatures, such as zinc) and cold chamber machines (used for alloys with high melting temperatures, such as aluminum). However, in both machines, after the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting.
Cold chamber die casting machine - Cold chamber machines are used for alloys with high melting temperatures that can not be cast in hot chamber machines because they would damage the pumping system. Such alloys include aluminum, brass, and magnesium. The molten metal is still contained in an open holding pot which is placed into a furnace, where it is melted to the necessary temperature. However, this holding pot is kept separate from the die casting machine and the molten metal is ladled from the pot for each casting, rather than being pumped. The metal is poured from the ladle into the shot chamber through a pouring hole. The injection system in a cold chamber machine functions similarly to that of a hot chamber machine, however it is usually oriented horizontally and does not include a gooseneck channel. A plunger, powered by hydraulic pressure, forces the molten metal through the shot chamber and into the injection sleeve in the die. The typical injection pressures for a cold chamber die casting machine are between 2000 and 20000 psi. After the molten metal has been injected into the die cavity, the plunger remains forward, holding the pressure while the casting solidifies. After solidification, the hydraulic system retracts the plunger and the part can be ejected by the clamping unit. The clamping unit and mounting of the dies is identical to the hot chamber machine.

Custom Process
To receive accurate cost and time estimates for your custom casting project, please provide the following information of the parts you are requesting,
• Drawings and specifications:
including but not limited to material, dimensional tolerance,
machining requirements, actual or estimated weight and inspection
requirements.
• Material: a specific metal grade or the preferred material and desired
properties.
• Quantity: Include the anticipated volume, both present and future. Quantity
has a large influence over production method, pattern development,
and overall cost.
• Quality acceptance criteria, such as nondestructive test, mechanical testing are all critical considerations for a quote.
