Die Casting Manufacturer

Like many employees of companies in the processing and manufacturing aluminium industry we too had to witness the loss of time and money due to the difficulty of finding qualified personnel or suppliers who possessed the know- how to quickly provide accurate answers to concrete questions. This fact led to the idea of a branch specific know-how management system which could enable the exchange of experience, knowledge and ideas. The realization of such an exchange directed us toward a type of cyclopedia in which, next to basic knowledge, also technical papers and specific topics would be featured. Besides technical literature, sources for this information would be branch companies and their employees. Companies and personnel which present themselves and their competences would be recognized on the market as useful suppliers. Therefore it made sense to offer next to the cyclopedia a comprehensive directory of manufacturers and suppliers, in which branch companies can present themselves. The internet is the best medium for this challenge. Online we can provide a service which is comfortable and efficient for our users at the same time. Right in the beginning it became clear to us that our quality requirments would lead to very complex structures, but users would need useful replies within a short period of time, especially concerning possible deadlines. With the founding of the company Alu M.®AG in Münchenstein, close to Basel, in June of 2002, we also created the website CNM TECH- our product and realization of our elucidated vision. Its attractive content and beneficial service make CNM TECH the leading online information platform, communication center and market place for all players in the broad and diverse aluminium industry.
Yours truly

Metal Die Casting and Metal Foundries

Is Metal Casting the “Most Fundamental” Industry?

On the North American Die Casting Association’s website, the association says that metal die casting is America’s most fundamental industry. Is this true? Should you take a metalworking association’s word for that kind of statement? I think it’s impossible to evaluate one sector of the economy as “most fundamental,” but they’re certainly right that metal casting is an extremely important industry.

What I’ve found in the time that I’ve been writing about industry is that different disciplines and industrial sectors are inseparable from one another. The computer industry and the casting industry, for example, are codependent. The computer industry needs casting companies to make heat sinks and other vital computer components, and the casting industry needs the computer industry to manufacture hardware that can manage its CNC manufacturing processes. Think of any example of a sector in industry and I guarantee that you’ll find at least one other sector that it is codependent with.

Die casting companies are no exception to this rule. The low hanging example fruit, when it comes to die casting, is, again, the computer industry. Many computers involve at least one die cast part, and die casting operations are often managed by CNC hardware and software, which the computer industry produces. But there are many other examples as well. Die cast parts are involved in the equipment that is used to extract raw metal, and that raw metal can then be used to make more die castings. There are many other examples.metal die casting

Die casting is an excellent example of the codependence and interdependence of industrial sectors. Even though the NADCA insists that metal casting is the most fundamental industry, bear in mind that no industrial sector could exist without depending on other sectors. This is the reality of a developed, industrial economy.

Metal Foundries: A Look Inside

A metal foundry is a place where metal is transformed from its base material into useable ingots that can be transformed into usable metal pieces. Some foundries shape their own metal pieces, while others ship the finished metal off to other factories for further processing.

There are a variety of different metals that can be used to create metal casting and shapes. Usually, aluminum and iron are used, but other metals, like bronze, steel, copper, tin, magnesium, and zinc are also processed in a factory and shaped into parts using metal casting. Most metal foundries use a special kind of metal casting to create ingots or other metal shapes for further processing. A metal foundry typically uses a multi-step process to finish the metal pieces.

First the metal is melted in a large container and any impurities are removed. If the metal will be a combination of metals, they are added at this point and mixed together. Most foundries use a furnace to melt the metal. After melting, some metals require degassing. Degassing is the process of removing hydrogen in the metal. Too much hydrogen produces a porous metal that has little use. Degassing is done by bubbling nitrogen or argon into the metal while it is still in liquid form.

After melting and degassing, the metal is poured into a mold. Different foundries will have different molds available, such as ceramic molds, sand molds, investment casting, die casting, billet casting, or lost-foam casting. Usually the metal is poured into the molds using robotic pouring systems.

The metal is allowed to cool, then removed from the mold. The metal piece then goes through a degating or deburring process, which removes unwanted pieces from the mold. The metal piece then may be heat treated to give it extra strength, or simply cleaned and polished for final use.

When to Use Die Casting

Metal Casters have the luxury of choosing between several casting methods to accomplish their goals. Often times the metal caster chooses one method and sticks with it for several years until need directs him to another. Of course, there are those adventurous few who like to sample each casting method to find the best fit. Sure, sand casting might be the most popular but what about Lost Foam or Investment?

What about Die casting?


Die casting is used by industrial foundries and manufacturers to create practically anything and everything, such as die cast cars. Many small foundries, like the one in your garage, backyard, of workshop may find that die casting is really just not economical. But who said that having fun and trying new things was ever economical? This process we aslo called high pressure die casting or pressure die casting, The process of Die Casting involves a simple concept. The molten metal is injected with high pressure into the mold or mold cavities. The mold used in die casting can have several small civilities of either the same pattern or different pattern.


The name Die Casting comes from the molds which are called dies. These molds are reusable and are often made from steel but other alloys can be used as long as they can withstand high pressure. The reason dies must be created from metal and not from sand or other material is due to the high amount of pressure used to get the molten metal into the mold. If sand molds were used in a Die casting procedure then the mold would crumble. There are plenty of advantages of using dies in a casting procedure which makes this method desirable for anyone wishing to create a high volume of similar castings.

Die casting is perfect for anyone that needs to make a lot of the same thing without any quality or pattern deviation. This is especially helpful in certain industries where quantity and quality count. Many hobbyists may have no use for die casting on a practical basis but will often try at least one Die casting for the sake of trying.

There are two types of machines used in the Die Cast procedure. These machines are essentially the same and are called the Hot-chamber and the Cold-chamber.

The Hot-chamber machine melts the alloy and feeds it into a section of the machine referred to as the gooseneck. A piston then forces the alloy into the mold. A separate furnace is not needed but the draw back of this is that metals with higher melting points can not be used.



The Cold-chamber is used for metals that can not be used by the Hot-chamber such as aluminum and copper. A separate furnace is needed to melt the alloy which is then poured into the injection cylinder and then shot into the mold.

The advantages of using Die casting vary but the most noticeable advantages are the repeated quality, smooth casting surface, and the quick production of casts. While the initial cost of Die Casting exceeds several of the other casting procedures, those that need a high number of casts in the shortest amount of time possibly will benefit greatly from the investment.

Die casting is commonly used to create commercial goods as it yields a high volume. The molds, or dies, used vary in life cycle depending upon the material used to create the die. The die can have one cavity or several cavities depending upon the need.

Everyone should try Aluminum die casting, magneium die casting or zinc die casting at least once if they can afford the initial cost. Besides, who knows when you’ll need a small battalion of metal soldiers which can be made quickly and easily with die casting.

Metal Casting

Charlie Chan arrives in Shanghai at the behest of the U.S. government to help stop an opium smuggling ring. He receives a warning aboard ship not to stop in Shanghai. He is met by his Number One Son, Lee Chan, as well as Philip Nash and his fiance, Diana Woodland. Charlie is the guest of honor at a banquet held that evening, hosted by Sir Stanley Woodland (David Torrence in an uncredited role). When Sir Stanley opens a box to give a handwritten scroll to Charlie, he is shot and killed by a gun inside the booby-trapped box. Charlie meets with Colonel Watkins, the commissioner of police, and agrees to investigate the crime. The next day, American FBI man James Andrews arrives in Shanghai, accompanied by his valet, Forrest (Gladden James in an uncredited role). That night, an assassin shoots what seems to be a sleeping Charlie Chan in bed. But Charlie, suspecting another attempt on his life, rigged a dummy and escaped death.
Watkins, Nash, and Woodland try to meet with Andrews. Nash sneaks off and goes through Andrews’ briefcase, suitcase, and other papers. Charlie arrives, and while he is speaking with Andrews is nearly shot. Charlie and Andrews managed to retrieve the gun, but the assassin escaped. A fingerprint on the gun reveals that Nash is the likely suspect, and he is arrested. A letter Nash had stolen from Andrews’ things seem innocuous, but Charlie takes it as evidence. Charlie returns to his hotel and meets with Lee. They receive a note from Col. Watkins asking them to come to an office downtown. They check with police headquarters, which assures them the note is genuine. Charlie goes, but Lee realizes the note is fake when Col. Watkins calls soon thereafter. Charlie is kidnapped and taken into a room to meet with a mysterious Russian (Ivan Marloff). Lee tries to save his father, but is caught. The two bluff their way out of danger, and after a brief fight manage to escape.

That evening, Charlie and Andrews meet with Col. Watkins. Diana Woodland arrives and asks to see Nash; her request is granted. But Diana sneaks Nash a pistol, and the two escape. Later that day, Andrews and Charlie return to the house where Charlie was held. The gang has left, but Charlie finds an ink pad in the fireplace and takes it as evidence. Lee shows up dressed as a beggar, and Charlie sends him home. Oddly, Charlie arrives at the hotel first. Lee shows up later, and reveals that he saw their kidnapper in a taxi on the street and followed him to the Cafe Versailles. Moments later, Andrews calls and summons Charlie to his apartment. Before he leaves, Charlie sends Lee off on a secret mission. Charlie arrives at Andrews’ apartment, where the FBI agent has caught a gangster involved with the Marloff gang. After a punch to the jaw, the gangster reveals that the Cafe Versailles is where the opium gang is hiding out. Andrews calls the police, and asks them to meet them at the club. Charlie and Andrews leave for Cafe Versailles. After Charlie and Andrews depart, Andrews’ valet, Forrest, frees the gangster and the two leave. At the club, Nash (disguised as an able seaman) sees some of the Marloff gang heading toward the basement and follows, but is captured. Charlie and Andrews arrive moments later, and follow a gang member into the basement as well. The basement is where opium is being shipped out via riverboat, reached by a trap door. Andrews urges Charlie to go first, but Charlie hesitates when his flashlight mysteriously refuses to work. The police arrive by boat, and after a brief shootout capture the gang.
Charlie surprises everyone by arresting James Andrews. Lee Chan reveals that his father sent him off to cable America, and he has just received a reply which indicates that the real Agent Andrews was murdered in San Francisco three weeks earlier. The false “James Andrews” is really the leader of the Marloff gang, and intended to have the gang murder Charlie in a shoot-out when they descended through the trap door. Charlie knew Andrews did not really call the police, and had Lee summon them instead. Nash’s escape from police custody was planned by Charlie. Charlie reveals that Forrest used the ink pad to put Nash’s thumbprint on the revolver to frame him. Nash is declared innocent, and Andrews and Forrest go to jail. External links
