Die Casting Tooling for Zinc

The Role of Zinc Die Casting Tooling. Zinc parts are produced with the zinc die casting tooling in the zinc die casting machine. The components of the zinc die casting, as well as the zinc dies are alloy tool steels that are divided into two parts. These 2 parts are the ejector die half and the fixed die half, which permit the removal of the castings from the die casting machine. Modern dies may include cores, movable slides or other portions that can produce threads, holes, and shapes as may be required in casting. The sprue holes in fixed die half permit molten metal into the die and fill the cavity. Dies also have the locking pins that serve to secure the two halves. It also includes ejector pins that help in taking out the cast parts and openings for lubricant and coolant.

When the machine for die casting shuts off, the 2 die halves will be held together and locked by the hydraulic pressure of the zinc machine. The die parting line is the machine’s surface wherein the meeting and locking of the ejector as well as the fixed halves happens. The total area of the part’s surface being die casted, the pressure and the die parting line’s measurement needed in injecting metal to the cavity’s die manages to determine the machine’s clamping force.

What people refer to as those die casting molds and insert dies made of zinc are what is referred to as zinc die casting tooling. This tooling is available in various styles, shapes, and sizes. It comes in either 1 or more cavities. Zinc die cast tools varies due to cavity inserts as well as trim dies.

Zinc Alloy Die Casting Processes

Die Casting Processes with the Use of Zinc Alloy. Die casting is the process by which molten ferrous metal, e.g., zinc, magnesium, copper, lead, tin, aluminum, etc., are molded into cavities and placed under pressure to form. The method of die casting is ideal if the application needed is in large quantity and should be well-detailed and has fine quality. Zinc is a non-ferrous metal that is popularly used for die casting. This is due to the fact that zinc alloys have many characteristics that far exceed other metals. Zinc alloys have high strength and hardness, has high thermal and electrical conductivity, low cost, good finishing characteristics, outstanding fluidity, and excellent corrosion resistance among others.

In the zinc die casting process, two processes are involved, the hot chamber method and the cold chamber method. These two zinc die casting processes make use of various types of metal alloys during the production of parts in the zinc die casting process. The hot chamber method involves the process wherein a steel die is filled with a pool of molten metal, all the time maintaining pressure, until the metal hardens. The second process, the cold chamber method, involves the use of two separate chambers, first to melt, then to hold the melted zinc alloy before it is poured into a shot cylinder and afterwards inject them to the die casting die. Before, the metal alloys used in Zinc die casting processes are tin and lead. The zinc alloy however gained popularity and is now the first choice when it comes to die casting.

Cold Chamber Die Castings

Filed under: Cast Parts — Tags: — admin @ 4:39 pm

Cold Chamber Die Castings. Our technology had greatly improved through time; nowadays, everything is possible. One of those processes that were bought upon by technology is die castings. This refers to the procedure of forcing molten metal which is under pressure into the mold cavities. Almost all die casting is created from non-ferrous metals such as copper, zinc, magnesium, aluminum, tin and lead. This process is specially needed for applications wherein a huge quantity of small to medium parts are required and must possess a good detail, well surface state, and dimensional consistency. Zinc Castings are typically made using the hot chamber zinc die casting.

Cold chamber die casting procedure, this employ a higher-melting point alloys like magnesium and aluminum for example. Because the cold chamber is situated outside the furnace, this process calls for a means of competently moving the molten metal starting from the holding furnace down to the cold chamber. Basically, the cold chamber is located in the middle of the die and the die casting machine front platen. In transporting the molten metal, this is normally done with the help of a ladle mechanism which may be operated manually or automatically in casting aluminum alloys. In cold chamber die castings, the time consumed may vary. For small machine, it can last for 10 seconds and 2 minutes on the other hand for large machine.

Basically, cold chamber aluminum die casting is used during times when hot-chamber machines are not available. This procedure brings smooth cast surfaces and this help lessen or get rid of secondary machining operations while ensuring fast production rates.

Cold Chamber and Hot Chamber Die Castings

Filed under: Aluminum Casting Parts,Cast Parts,Zinc Casting Parts — Tags: , — admin @ 4:47 pm

Cold Chamber and Hot Chamber Die Castings. Die casting process basically consists of injecting molten metal under high pressure into a mold or die. It is a versatile process of creating reusable steel molds. The molds are designed to produce complex shapes with high degree of accuracy and repeatability. There are two fundamental methods in die casting, hot chamber and cold chamber.

Hot chamber die castings are used for alloys with low melting pot that do not readily attack and erode metal pots, cylinders and plungers. Typical hot chamber makes zinc parts. While cold chamber die castings are used for alloys with high melting points, most common of which is aluminum.

Cold chamber die castings employ manual method in pouring molten metal. A hydraulic operated plunger will seal the cold chamber port. Then, it forces metal into the locked die at high pressure. The machine uses a separate melting furnace and weighs several tons.

The cold chamber die casting machine is located outside the furnace, as compared to hot chamber. Thus, it requires a means of moving the molten alloy from holding furnace to the cold chamber which is attached between the die casting machine front platen and the die. Transporting the molten metal is typically done with a ladle mechanism. Cycle times can range between 10 seconds for smaller machines and up to 2 minutes for larger ones.

Cold chamber die casting is more popular in the manufacturing industry because of its cheaper production cost and durability. It may be more complex than hot chamber die casting but its dependability is more advantageous. Aluminum die castings are made using the cold chamber process.

Hot Chamber And Cold Chamber Die Casting

Filed under: Cast Parts — Tags: — admin @ 4:29 pm

Hot Chamber And Cold Chamber Die Casting. In the process of die casting, molten metal in injected forcibly into mold cavities, or “dies”, under very high pressure. Because this method of molding metal is extremely versatile, die casting is widely used as a method for forming metals into specific shapes. While it may use a similar process as mold casting, die casting uses pressures of up to 10 to 210mpa to inject metal into the die. The resulting material exhibits uniformity of parts, dimensional accuracy, and smooth surface finishes.

There are many different materials used in die casting, such as copper, zinc, tin, magnesium, and lead. However, aluminum die casting is the most widely used compared to these other materials as the metal is more malleable, and is good for creating large size cold chamber die castings, to die castings composed of tiny and complex parts.

There are two processes used for die casting, namely the cold chamber which produces cold chamber die castings, and the hot chamber process. To produce cold chamber die castings, a cold cylinder is injected with molten metal. With less time exposure given for the metal to be propelled into the mold, cold chamber processing is more often used for metals that easily meld with iron at very high heat. The cold chamber process is also used for metals that have high melting points.

On the other hand, in the hot chamber zinc die casting process, the pressure found in the die cavity connected to it becomes permanently a part of the molten material. A plunger is propelled toward an area that is non-pressurized, uncovering the inlet port appended to the pressure cylinder.
