Die Casting

Die casting is an automated casting process that forces molten metal such as zinc, copper, aluminum, magnesium, lead and tin into a mold cavity with high pressure and high speed. The molds are also called tools or dies, which are designed especially for each product, so die casting can fabricate metal parts with high accuracy. It is a prefect technique for making small and medium-sized metal parts in large quantities.

MOKO Technology is specialized in die casting technique, we have top-tier casting machines including hot-chamber die casting and cold-chamber die casting machines, and we have offered die casting services for many projects ranging from different industries like electronics, healthcare and automotive.

The Advantages of Die Casting

High Accuracy: The die-cast process makes sure that the metal parts are made with precise dimensions, and the parts from different batches can be uniform and consistent only if the mold is not changed.

Good Performance: Die-cast products are featured with high corrosion resistance, high strength and hardness and durability, as there are no welded parts.

High Production Efficiency: Its short cycle time and automation  allow the manufacturer to fabricate thousands of metal parts quickly, and there are no extra processes needed.

Versatility: It can be applied to produce metal parts with different alloys and various shapes even some complex shapes.

Die Casting Processes at MOKO

Hot-chamber Die Casting

Hot chamber casting, also known as gooseneck machine, is a process that has a quick cycling time(about 15 cycles per minute). It is suitable for low-melting alloys such as zinc and magnesium. The feature is that the metal is heated in the casting machine as there is a built-in furnace to melt metal, and the molten metal would be finally forced at high speed and high pressure into the mold through the gooseneck. But we should notice that the hot-chamber die casting is not suitable for aluminum, as it would carry iron out of the molten pool.

Cold-chamber Die Casting

When you hear the name “cold-chamber”, you must wonder that if such a process is carried out in a cold environment? The answer is no. We still need to melt metals, but the furnace is not built-in. Before we start cold-chamber casting, we need to melt metal in a separate furnace, and transport a precise amount of molten metal into the cold-chamber machine(the temperature of the chamber is the room temperature), and then it would be forced into the die by a hydraulic or mechanical piston. Cold-chamber die casting has a slower cycle time and it is perfect for high-melting alloys such as aluminum.

Hot-Chamber Die Casting VS Cold-Chamber Die Casting:

Temperature Range: Hot-chamber die casting is suitable for low-melting alloys and the maximum temperature it can handle is around 450°C. While the cold-chamber die casting can handle metal alloys with a temperature of about 600°C.
Furnace Location: The furnace is built inside of the hot-chamber machine, but for the cold-chamber machine, the furnace is separated.
Production Time: Hot-chamber die casting has a faster cycle time than cold-chamber die casting that requires manual operation of the molten metal.
Tool Life: Hot-chamber machine has a longer lifespan as it handles low melting alloys, which has less impact on the machine.
