Die Casting Process

/in , , , , , , /by

There are many type of die casting process that you can use to make die casting parts and metal casting parts, below is some of die csating process for your reference.

Investment Casting

Investment casting, here we often called lost wax casting, is regarded as a precision casting process to fabricate near-net-shaped metal parts from almost any alloy. Although its history lies to a great extent in the production of art, the most common use of investment casting in more recent history has been the production of components requiring precision, complex, often thin-wall castings.

We can use investment casting to offer many ferric and non-ferric castings, such as copper alloy casting, aluminium die casting and Steel investment casting, stainless steel casting, high resistant steel casting , carbon steel castings, Cutting Tool steel castings, low alloy steel castings, high speed steel alloy, heat resistant steel casting, corrosion resistant steel casting, wear resistant steel, abrasive resistant steel castings and other specialty steel casting, . And also available for the service for post-treatment, such as blasting, heat treatment, polishing, machining, zincing, plating, anodizing, plus good service, we hope we can earn your trust in this field.

The casting tolerance our foundry can reach a precision from CT3 to CT9 according to stand ISO 8062 by choosing different investment casting craft and materials.

Investment casting are always classified in 3 types, one we called here is American style silicon gel process(with green wax and better sand) with very smooth surface, tight tolerance, suitable for small part making widely used for stainless steel, carbon steel. It’s different with Russian style investment casting actually called soluble glass process(with white wax and rough sand)with relative rough surface, bigger tolerance, suitable for large part making more than 1.00KGS especially for carbon steel, alloy steel, sometimes also for ductile iron and grey iron. And the complex shell process just fall between the 2 types silicon gel process and soluble glass process。

Sand Casting

Due to its apparently benefits: low cost, flexible process, competence in providing complex inside shape and intricate outer shape, sand casting earned its important role in today’s casting industry, it is Used with Most Pourable Metals and Alloys.

We use sand casting craft to get gray iron castings, ductile iron casting, white iron castings, brass castings, bronze castings, aluminium sand castings, steel sand castings, nick alloy castings.

Sand castings are following in two molding process green sand and resin sand, our foundry providing with manual molding or machine molding.
The sand casting tolerance we can reach from CT8 to CT12 according to ISO 8062 standard, the higher precision required, the advancer sand casting craft will be choosen.

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.
