Die Casting Technology- Miniature Zinc Castings

Posted on 03/15/2013 by admin

Die Casting Technology – Miniature Zinc Castings. The technology of Zinc Die Casting has developed so much in just few years after it was introduced in public. It has contributed a lot in the industry of miniaturization. Now, even the smallest and the most complicated geometrical parts of the zinc can be die casted through a remarkable correctness, as well as several features like multiple cored-through holes, flash-free sculpted shut-offs, very thin walls and formed shapes. A process that is used to create zinc miniature is called Miniature Zinc Castings.

Miniature Zinc Castings is an accuracy manufacturing method, which offers cost-effective production, repeatability and accuracy, improved material properties, complicated geometries and design adaptability. The Miniature Zinc Castings method is particularly useful as a substitute for assembly, stamping and screw machining.

You will be surprised to know that it can only take one pound of modern zinc alloy to create 17,000 completed castings of zinc miniatures. Modern zinc alloy is definitely tougher and stronger than magnesium or aluminum and it provides better flexibility. Zinc parts can be created in smaller sizes, along with greater complication and finer element. The best thing about zinc is that it can be easily painted and plated in addition to the wide-variety of metals to give a scope of finish and feature selections.

There are many benefits that the Miniature Zinc Castings method gives to the users and component designers aside from providing a low-cost of component. Other benefits are finishing uniqueness and exceptional exterior quality, pleasant substantial properties, thin wall divisions, great mechanical properties and low-cost assembly.

The Process of Hot Chamber Zinc Castings

The Process of Hot Chamber Zinc Castings

A Hot Chamber machine is especially used for low melting point alloys like magnesium, zinc and copper, which don’t quickly damage metal hot chamber pots, plungers and cylinders. One popular hot chamber process used is the Hot Chamber Zinc Castings process. Because it provides high rate of productivity, more and more companies are using the Hot Chamber Zinc Castings process.

In the process of Hot Chamber Zinc Castings, strips or rods of metal zinc will be melted inside a hot chamber at about 700-800 degrees Fahrenheit. While the zinc metal is inside the hot chamber, the gooseneck, commonly called as the shot sleeve, will be plunged into the hot chamber. Then the molten zinc metal is injected straightly from the hot chamber, inside the pair of die halves that are attached in the Hot Chamber Zinc Castings machine.

After that, the molten zinc metal will be infused with hydraulic pressure inside the pair of die halves. The molten zinc will be held under a high pressure in anticipation of the solidification of the metal. The waiting time is commonly about 15 seconds, but it still depends on the size of the parts. Afterwards, the pair of die halves will be opened and all the parts will be removed either by hand or with the use of a machine. Finishing touches like assembly, chrome plating, anodizing, painting, precision machining, tumble deburring and trimming will be followed.

That’s how the process of Hot Chamber Zinc Castings works. It may look simple but it requires regular monitoring and hard work to produce a perfect material.

Characteristics of Die Casting Zinc Alloys

Posted on 03/01/2013 by admin

Characteristics of Die Casting Zinc Alloys. Different types of zinc alloys are commonly produced by the Zinc Die Casting process. Zinc alloys are applicable for broad variety of products due to excellent impact strength and high flexibility. Die Casting Zinc Alloys may be cast with thin walls and outstanding surface sleekness, which makes the preparation for painting and plating somewhat simple. In the generation of alloys, it is important that you use high-purity zinc metals. The dimensional stability and lasting integrity of the alloy’s toughness is guaranteed through low limits on cadmium, lead and tin.

These are the different characteristics of Die Casting Zinc Alloys:

1. Excellent corrosion resistance
2. 100% recyclable
3. High-quality finishing attributes
4. Has the capability to cold form that eases joining
5. Raw materials are inexpensive
6. High thermal and electrical conductivity

Another characteristic of Die Casting Zinc Alloys is its low melting point. This characteristic makes the zinc alloy sufficiently flexible in order to use it for cold chamber casting equipment and hot chamber casting equipment.

Die Casting Zinc Alloys rigidity and high strength makes it the perfect substitute to fabricated, stamped, pressed and machined items. The complicated net-formed zinc casings with exact thin walls provide exceptional shielding properties and electrical performance to electronic connectors, chassis, shields as well as frames for hand-held telecom and computing equipment. The small and complex elements of Die Casting Zinc Alloys are used in several electronics and consumer electrical applications such as shutter devices in cameras, heat sinks, precision interlocking gears, hard disk drives, portable computers and mobile phone antennas.

Die Casting Company – How it Helps the Economy

The industry of Die Casting has invaded the Northern part of America for many years now with the latest technology, innovative applications, and superior quality and higher productivity of metals. By way of producing high-quality die castings, the metal casting industry contributes a lot in the achievement of United States metal casting. In reality, approximately 90% of manufactured products are made of die castings by various die casting companies.

The Top Die Casting Company, which is known to be producing high-standard aluminum die casting, offers solution to your die casting dilemmas. They start their Die Casting Process by using the CAD Systems that has online transfer abilities. They also use the software called Nova-Cast Die Casting Mold Flow to help authenticate the gating, runner as well as venting design before finishing the mold tooling. The Top Die Casting Company uses different machines to produce excellent die cast materials, from modeling to polishing.

Another Die Casting Company is Premier Die Casting. The company offers CNC machining, product design, assembly and testing, metal finishing and aluminum and zinc castings.

One old company in the industry of die casting is the Advanced Die Casting Company, which has been established since 1920. The company offers aluminum and zinc die casting with the use of top of the line Aluminum and Zinc Die Casting equipment. They also have engineering and design support.

Because of the fact that the die casting industry gives $7.3 billion to the economy and gives more than 63,000 employments, it is safe to say that the industry plays a vital role in the United States economy.

Zinc Die Casting Process

Posted on 02/15/2013 by admin

Zinc die casting process

The process of zinc die casting involves the injection of molten zinc into molds or casts by using very high pressure. Four essential steps are undertaken in zinc die casting, first of which is spraying the mold with lubricant and closing the die cast. The lubricant is used not only to facilitate casting removal but also to contribute in controlling the temperature of the die during the casting process.

Next, high pressure is used to inject or shoot the molten zinc into the die. The pressure is maintained once the die is completely filled and the casting has solidified. After the casting has cooled enough, the dies are then opened and ejector pins remove the shots inside. Scraps are separated from the castings, oftentimes through a special trimming device in a hydraulic press or power press. Secondary operations may be necessary in some zinc die casting that could entail plating, painting or buffing or tapping a hole in the cast parts.

The high-pressure injection is the most critical step in zinc die casting. The entire cavity of the die cast or mold has to be completely filled with the molten zinc before any of the casting’s part solidifies. If the injection or shot is swift enough, there won’t be casting discontinuities even in thin, difficult-to-fill sections of the die cast.
