Aluminum Heat Sinks. A heat sink is an essential component of any device that accumulates excess heat. Usually, these devices are used for extended periods of time which is the main contributor to the heat build-up. To maintain their functionality, …

Hot Chamber or Cold Chamber Die Casting?
Hot Chamber or Cold Chamber Die Casting? Die casting is a very common process of manufacturing metal parts. In the process of high pressure die casting, molten metal alloy such as aluminum alloy is injected into a mold called a die. The metal is left in the steel mold until it solidifies and then it is removed.
There are two types of machines that are used in die casting. First is the hot chamber machine, also called piston or gooseneck machine, and the second is the cold chamber machine. The hot chamber machine has the metal injection device, or gooseneck, submerged in the molten metal within the holding furnace. This machine works by having the gas or oil-powered piston retracted and allowing the molten metal to fill the gooseneck. The molten metal is then forced out of the gooseneck by the piston and the metal goes into the die. Not all metal alloys can be used in the hot chamber machine. Due to this, cold chamber die castings must be made. Aluminum and metals with high melting points like copper, magnesium, and zinc alloys need the cold chamber machine. The cold chamber machine doesn’t have the piston immersed in the molten metal. Before using the cold chamber machine, the metal must be melted first in a separate furnace. Then the molten metal is brought to the cold chamber machine and injected into a cylinder and a hydraulic piston forces the metal into the die. Cold chamber die castings take longer to produce because the metal has to be melted in an unconnected furnace.
It doesn’t matter whether parts are hot chamber or cold chamber die castings. Both these products are made using the wonderful manufacturing process known as die casting.

Pace Industries announced closing of Monroe City die casting
Pace Industries announced closing of Monroe City die casting. The management of Pace Industries announced the closing of its Monroe City Division die casting facility located at 135 Front Street Thursday, May 14.
The operation, formerly known as Kuhlman Die Casting, was built in 1951. Pace Industries acquired the business in 1990.
Continuing assistance will be provided to Monroe City associates by Pace Industries during the closing process. The company is currently scheduling meetings with the Missouri Division of Employment Security and the Missouri Department of Economic Development.
The plant closing is a WARN-covered event. WARN is the Worker Adjustment and Retraining Notification Act. The closing will affect approximately 190 production, administrative and management employees. Employees will be offered the opportunity to work during the period of the closing, which is projected to be July 14.

Metal Die Cast in the Cold Chamber
Metal Die Cast in the Cold Chamber. In the field of metallurgy, the cold chamber process is known as one of the two major types of die casting methods. The other one is called the hot chamber process. If you see molded metal parts with a high melting point, they are most probably produced by a cold chamber machine. Cold chamber die castings might be made out of aluminum, magnesium, and copper.
These cold chamber die castings go through external furnaces. The metals are then poured into a cold chamber in the machine. The cylinder and plunger are not submerged in molten metal as is the process with low melting point metal alloys in a hot chamber process. These huge machines use hydraulic power to force the poured metal into the die mold. It is a slower process but the machines used for cold chamber die castings generally last longer. This and its ability to produce metals with a high melting point into precision parts make it useful for machinists, metallurgists, metalworkers, engineers, and manufacturers of our modern gadgets.
Die casting is only one of the processes used to shape metal to our needs. There is also forging, rolling, sintering, machining, fabrication, metalworking, and a number of different casting methods. Then there are the techniques of joining one metal to another which are soldering, welding, and brazing. There are also other techniques such as annealing, tempering, quenching, plating, thermal spraying, and case hardening. All these metalworking processes have contributed to the development of our world as we know it today.

Cold Chamber Die Castings – A Look at the Procedure
Cold Chamber Die Castings – A Look at the Procedure. Die casting is a method that is in one way or another similar to that of permanent mold casting. The only point of difference lies in the fact that the metal is actually injected into the mold by using a high pressure. This enables the production of a more accurate dimension and better surface finish, so to speak. On many occasions, the use of post machining can already be eliminated since the output is totally great. Light machining procedures may be required in some instances just for the purpose of sizing up the dimensions. Now the cold chamber die castings are also among the many methods employed these days.
With the popularity of cold chamber die castings comes the usefulness of zinc-aluminum alloys. It is due to the fact that among other alloys, the zinc-aluminum alloys have high melting points. The cold chamber is also known as the cylindrical sleeve and it is where the molten metal is poured. The medium used is either a manual hand ladle or an automatic ladle. There is likewise a hydraulically operated plunger which closes the cold chamber port and then forces the metal directly towards the locked die using high pressures.
In terms of the procedure of cold chamber die castings, the molten cast metal that is inputted into the cold chamber or cylindrical sleeves experiences a reduced time exposure to the plunger or its walls. Along with aluminum alloys, the copper alloys are also used along with iron because of their properties which are very much conducive for use with higher temperatures.

Aluminum diecaster Quad City
Aluminum diecaster Quad City to permanently close plants July 12
Washington (Platts)–14May2009 US aluminum diecaster Quad City Die Casting will permanently close its three plants on July 12, and recently sent out a Worker Adjustment & Retraining Notification notice to its approximate 100 employees that they will soon be out of a job, according to spokeswoman Linda Norberg.
Norberg declined comment on how much order levels have declined recently or if the company was up to date on its payments to suppliers. She would only say these are “tough times.”
She said, “When the economy hit, that did us in. Our customer orders have not come back. All sectors declined.” Quad City’s largest customer is Kawasaki, but its plants also service various other markets. The company only has a small exposure to the struggling automotive sector. It services customers in North America and Europe.
Quad City’s main plant is in Moline, Iowa (aluminum and magnesium diecastings), but it also has plants in Red Oak (aluminum and magnesium diecastings) and Davenport (zinc diecastings), Iowa. The plants make parts ranging from 5 lb to 20 lb, according to its website. The company was established more than 50 years ago.
