Die Casting Molds 101: How The System Works.

Die casting molds can be called by a host of names including die casting tooling, die casting dies or even insert dies. However, to simplify matters, these die casting molds may be simply referred to as “die casting tooling”. Regardless as to whether the dies are used in cold chamber machine production or hot chamber machine production, the principle behind its use is the same.

Die casting tooling molds come in two halves: the cover half and the ejector half. These two pieces are usually secured with locking pins that are now automatically fastened and released. The cover half is the immovable part. This remains as is all throughout the operation and usually does not contain any holes or passageways. The ejector half, on the other hand, can be detached during production since this is integral in the automatic ejection of the pieces within the dies. This half also contains spruce holes where the molten material is allowed to be squeezed through and eventually fill up the die cavity.

With more sophisticated dies, especially those that are designed to have pieces that have holes and tubes running within, the ejector half usually contains the gates (inlets) and runners (passageways) where it can route the molten material to. When the molten has taken the desirable shape, die casting mold tooling usually utilize ejector pins to automatically remove the pieces from the dies. Some machines even have openings for coolants (to speed up the cooling process considerably) and lubricants (in preparation for the next stage in production.)

Various Aluminum Casting Processes

Filed under: Aluminum Casting Parts,Cast Parts,Die Casting Company — Tags: , , , — admin @ 6:06 pm

Various Aluminum Casting Processes. Casting is a process which involves the pouring of a liquid material into a mold, which is shaped as desired, and then the liquid material is allowed to cool down to solidify. The shaped material is then ejected out of the mold afterwards.

Aluminum is one of metals that are commonly used in the casting process. There are various Aluminum casting processes, these are: sand casting, investment casting, permanent mold casting, and die casting. The simplest and the most flexible and most popular method among these is the sand casting method. It is the most cost-effective in the production of parts which require small quantities and can be used in molding any shapes through the fine sand and binder mixture. After casting, the sand molds are either hauled to land-fills or reconditioned in order for the sand to be reused. For repeatable production from various metals and high performance alloys, the use of investment casting is more appropriate. This method is commonly used for small castings and is also used in the manufacture of aircraft door frames. Investment casting, as compared to the other methods of aluminum casting process, is an expensive process. Permanent mold casting is typically used for non-ferrous metals. It is stronger and less expensive as compared to sand castings in terms of production requiring large quantities. It uses a vacuum in forcing molten aluminum into the metal molds. Among all these methods, die casting is the one which is popular in terms of usage in the aluminum casting processes. It is applicable in both ferrous and nonferrous metals and is the most appropriate in the production of parts which require more details.

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.

The Advantages of Cast Parts Process

Filed under: Cast Parts — Tags: — admin @ 5:59 pm

The Advantages of Cast Parts Process. Die casting is process that involves the use of high-pressure in injecting molten metal into mold cavities which are shaped as desired. Die casting is frequently used in the castings of nonferrous metals such as aluminum, copper, lead, magnesium, tin based alloys and zinc. This method is best appropriate in the manufacture of parts with small or medium size requiring large quantity production. This method is highly regarded as flexible, thus becoming widely used aluminum casting process in the metalworking industry.

Aluminum Cast Parts process is suitable in the production of parts which require various shapes, ranging from the simplest to the complex shapes. Die casting, as compared to other methods, is suitable for the fabrication of aluminum parts of various measurements as to its thickness. This method has an excellent dimensional accuracy and is known to produce parts which have smooth cast surfaces. It has the capacity to cast thinner walls as compared to sand casting and permanent mold casting. Through this method, threaded inserts, heating elements and high strength bearing surfaces can be cast-in. This method also lessens or eradicates the need for secondary machining operations. Another feature of the use of this aluminum die casting process is that it has rapid production rate and has a casting tensile strength as high as 415 MPa.

Cast Parts uses a system which has a fast cycle time and has a convenient casting machine for melting the metal. Die casting method uses two types of die casting machines: the hot-chamber machines and the cold-chamber machines.

Aluminum Sand Casting Process

Filed under: Cast Parts — Tags: — admin @ 1:52 am

Aluminum Sand Casting Process. Sand casting is one of the various aluminum castings processes. Sand casting involves the used of sand mixture in molding the molten liquid (metal). In this process, the first step is to create a mold in the sand, next is to integrate a gating system, take out the pattern, pour in the molten metal into the mold cavity, let the metal to cool down to solidify, and lastly, break away the sand mold and remove the casting.

When using the sand casting process, a pattern of the desired shape is used. This pattern can be made up of wood, plastic or metal. A single pattern can be used for simple designs, while complex designs usually have split patterns. The split pattern is divided into two parts, the upper part is called the cope, and the bottom part is called a drag. In the process, the mold is filled up with either a casting sand or green sand. Chills can be placed in the mold in order to control the solidification and metallurgical structure of the metal.

Aluminum sand casting process is an inexpensive process for manufacturing aluminum cast parts. It is cheaper as compared to other aluminum casting processes such as die casting and investment casting. Sand casting can be used in both high-temperature and low-temperature metals but is usually used in the processing of low-temperature metals such iron, copper, aluminum, magnesium, and nickel alloys. This particular aluminum casting process is quite similar to the plaster cast method. The pattern is placed in a box called flask and then filled with sand.
