Magnesium Compared to Zinc–Die Casting Characteristics in 2021

Posted on 03/24/2021 by admin

Magnesium Compared to Zinc – Die Casting Characteristics. Die casting has been getting lots of attention lately for its overall usefulness to the manufacturing process. How much it lessens production costs and production time has been proven to be very significant.

However, the metal being used for the die casting process has always been under debate. Both magnesium and zinc have their own properties which make manufacturers choose one over the other. Magnesium compared to zinc – what does one have as an advantage over the other?

Zinc is agreed upon by manufacturers as the easiest alloy to cast because it has very high ductility. Molten zinc alloy can easily be stretched and shaped into the molds used for die casting. Zinc also has high impact strength, for die casts which need a lot of pounding and shaping to form.

Magnesium, on the other hand, is the easiest alloy to machine. After the die casting process, once the mold has done its job, machining is required for the finer details, and this is where magnesium shines because of its softness to machine over zinc. It is also much lighter than zinc, which is very important in the current trends of industry where lighter is better.

On paper, magnesium compared to zinc looks like a better metal to use in die casting. However, it is still of course up to the manufacturer which alloy to use for the process.

Die Casting Machine and How They Work

Posted on 03/19/2021 by admin

Die Casting Machine and How They Work. Die casting machines are of two basic types. One is the hot chamber machines. This is also called the “gooseneck machines.” The other type is the cold chamber machines.

To feed the die, the hot chamber machines depend upon a pool of molten metal. At the start of cycle, the machine’s piston is drawn back and this gives way for the molten metal to fill the “goose neck.” Piston then forces metal out of the gooseneck and sent to the die. This system has a fast cycling time and melting the metal in the casting machine is convenient. However, in this system, high-melting point metals cannot be utilized. Also aluminum cannot be used. Aluminum picks up iron. For this reason, hot chamber machines utilize zinc, tin and lead based alloys.

When the casting alloy cannot be used in hot chamber machines, then the cold chamber machines are used instead. Among these alloys are magnesium, aluminum, copper and zinc alloys with a big composition of aluminum. The cold chamber system has a shower cycle time. This is due to the need to transfer molten metal from the furnace to the cold chamber machine.

Since cast irons cannot withstand high pressures, the dies and die casting tools used in die casting are often made out of hardened tool steels. This makes dies very costly, and consequently high start up costs. There are also cores involved to cast features such as undercuts. Since they disintegrate due to high pressures, sand cores cannot be used in die casting and die casting tooling. Metal cores are used instead. Wear and erosion limit a die’s life. This is strongly dependent on the molten metal’s temperature.

How to Make Zinc Cast Parts in 2021

Posted on 03/12/2021 by admin

How to Make Zinc Cast Parts
You have probably heard about zinc cast parts, some of the most important elements that make the metalworking industry more reliable and profitable than ever. Zinc cast parts are made through the practice of the zinc casting process. Basically, the said process forces molten zinc metal under pressure that is high, right into tooling cavities, in order to form cast parts. This process is also referred to as the die casting process and, in some cases, may use another metal other than zinc. Both ferrous and non-ferrous materials can be used, such as zinc, tin, lead, and magnesium, to name some of them. For purposes of this article, however, zinc as the main material will be discussed.
The zinc casting process, which is a very tedious one, can produce zinc cast parts that are small to medium in size. As for their appearance, cast parts made from zinc are known to carry intricate, impressive details, as well as delicate and finely textured surfaces. What is most notable about he said process is its consistency as far as the dimensions of the cast parts are concerned.
In order to make zinc cast parts that are of high quality, zinc part castings need not be expensive. One of the benefits that the metalworking industry appreciates about the process is that it is very economical. Production costs are kept to a minimum because the parts only need the primary equipment. Tooling and screening afterwards are rarely required. The process to make zinc cast parts involves just a few additional things, namely injections, lubricants, and cooling tools.

Posted on 03/10/2021 by admin

Consumer Parts Die Castings – Fast and Easy. Die casting has proven to be a very efficient and effective process in creating different kinds of parts made from different kinds of metals and alloys. A prominent metal used in this process is aluminium. This metal is often used in Consumer Parts Die Castings as more and more industries see the value of using aluminium. Other metals used are zinc alloy and copper. Sometimes, even non metal materials are used such as rubber, plasters, resin and concrete. Whatever the purpose may be, Consumer Parts Die Castings is essential to several markets in industries around the nation, and all over the globe for that matter.
To start the process of die casting, the metal or material is first melted into liquid. This is so that the material can easily be poured into the moulds which have been premade. The moulds will give the metal its new shape and size. After the liquefied metal is injected into the mould, it will be allowed to cool. Once the mould has significantly cooled down, the material inside will then turn back to its original solid form, it will then be opened and a few finishing touches is all that is required to finish the product.
Consumer Parts Die Castings allow for consistency in the results of the product. It is a fast, easy, reliable and cheap process to undertake in making bulk orders of parts and other products which is why manufacturers all over the world prefer to use this method compared to other processes.
