In addition to being lightweight, aluminum alloys are also resistant to corrosion, maintain strength at high temperatures provide high dimensional stability when China Die Casting intricate geometries and areas with thin wall thickness. They also possess high thermal and electrical conductivity. Machining aluminum is easier as well when compared to other materials including iron, steel and titanium.

Seven of the eight most commonly used aluminum alloys are based on a system of eutectic composition, where 11.7 percent silicon is used as a reference point in grouping them.

Commonly Used Aluminum Alloys and Their Benefits

Alloy 380 is used in a variety of products including home appliances, furniture, power tools, automotive parts, electronics and lawnmower housings because it offers the best range of properties for both the finished product and casting. With a combination of 8.5 percent silicon, and 3.5 percent copper, alloy 380 also offers a tensile strength of 324 megapascal, or 47 kilopounds per square inch.

Alternatives to alloy 380 include alloys 383 and 384, which are more resistant to hot cracking, and they offer improved die filling characteristics during the casting of complex components.

When compared to other aluminum alloys, alloy 360 offers greater strength during exposure to higher temperatures. It also offers better resistance to corrosion.

Radiator Mould offers the highest ductility, or the ability to stretch under tensile strength, of all aluminum alloys.

Cycle time is another key aspect of die Die Casting Parts

Because die Die Casting Mould is so important to minimizing surface defects, measuring it should be a regular part of the production process. In general, measuring can be done three ways:

Hand-held probe, which is highly accurate but requires that you stop the machine

Thermocouple in the die, which is continuous but cannot capture surface temperature

Infra-red, which is relatively easy but not as accurate as the other methods

Here are approximate temperature ranges that will ensure good surface finishes:

MetalGood FinishAverage Finish

Aluminum250 - 315° C190 - 315° C

Zinc230 - 290° C190 - 290° C

Cycle time is another key aspect of die Die Casting Parts. The temperature is directly influenced by the number of pounds of metal fed through the die in the previous one or two hours. Maintaining a consistent cycle time is one of the most important things you can do to control die casting defects.

“How to Select a Die Casting Machine” – Andy Behler, Blue Ridge Die Casting Mould

Purchasing a die casting machine is a major investment for any die caster and how to select a machine should be made on more than price. Andy presented fundamental engineering to use for evaluating one machine versus another such as platen deflection, tie bar strains, and shot end controls. There is a lack of industry machine performance standards in die casting at this time thus the need for specific individual analysis by the purchaser.

This Executive Conference was a large success with high attendance and excellent speakers and topics.

Next year the Conference will be held in Key West, Florida.

Die Casting Vs. Metal Extrusion | Premier Die Casting

While die casting may be the most modern and popular form of metal shaping for manufacturing parts, there are certainly many others to consider. It can be helpful to know about a variety of metal shaping methods in order to best determine what process is right for you, your parts and your business. One type of metal shaping you may not be that familiar with is called metal extrusion. While metal extrusion is not appropriate for as many metal parts manufacture applications as some other metal-shaping methods, including die casting, it’s still useful to know what it is and how it works.

How Metal Extrusion Works vs. Die Casting

Die casting is a simple and modern way to create consistent, quality metal parts at high volume and low cost. Die Casting Parts typically employs aluminum, zinc or copper alloy, melting the metal and injecting it into a closed die in the shape of the parts you want to produce. The process subjects the metal to high pressure as it cools, resulting in a consistent and durable shape when the process is completed.
