Hot Chamber Zinc Part Castings

Posted on 03/28/2009 by admin

Hot Chamber Zinc Castings. The process of hot chamber zinc casting is a process that melts zinc using a 700- to 800-degree Fahrenheit furnace. Once the zinc is liquefied, it stays in the heat. A sleeve is placed in the heat and injected to the molten zinc metal, which is held together by the machine directly from the furnace into the two die halves.

The two halves of the die casting tooling are placed on the machine that keeps the two halves together and remains closed until the next step. Hydraulic pressure solidifies the metal within two to seconds depending on the size of the parts. After this the part is removed and ejected by hand or robotically, the halves are then opened. Trimming, precision machining, tumble deburring painting, chrome plating, anodizing, and assembly will follow.

The hot chamber zinc die castings is intended for zinc, copper, lead, magnesium and others on alloys with low melting point. The process does not destroy and erode metal furnace pots, plungers, and cylinders. The injection mechanism of hot chamber zinc casting machine is done by immersing zinc in the molten metal bath of a metal holding furnace. A port in the injection cylinder opens and the injection cylinder plunger rises, allowing the molten metal to fill the cylinder. One of the advantages of hot chamber zinc diecasting is the fast cycle-time and the easy steps of melting in the casting machine. Disadvantages of this system include the high-melting point metals that cannot be utilized. What’s mote, aluminium is not suited for this system because it picks up some of the iron while in the molten pool.

DieCastingZinc Die Casting Zinc Company

Posted on 03/26/2009 by admin

DieCastingZinc Die Casting Zinc Company. Zinc is one of the metals that have a wide range of use in the industry. It has found its importance in many industries, which include battery containers and ship and boat anodes. Zinc is most commonly used in the galvanized steel industry for its resistance to corrosion. It is also notably used in the automobile industry as die castings. For die casted zinc, the product is more popularly known as zinc die casting.

Die casting is one of the forming processes of metals. In this process, the metal is melted at its melting point, and is then poured out into molds or “casts” under a certain pressure. It is allowed to solidify under the same conditions. The melting point varies for most metals, and it has to be carefully noted as some other metals become brittle beyond certain temperatures. The desired shape is achieved by using metal dies, which are clamped together after the molten metal is poured on it. As the metal slowly cools and solidifies, the dies are opened, and the molded shape is ejected.

One of the advantages of zinc die casting company is that, one set of dies can be used for hundreds, and even thousands of casting process. Aside from this, because the process is sort of mechanical, it can actually be done at a faster rate, depending on the capacity of the machine, thus making this process inexpensive for mass production. Zinc diecasting company has indeed established its importance in the industry through its economical applications.

Miniature Zinc Parts

Posted on 03/26/2009 by admin

Miniature Zinc Parts A Great Invention of the Modern World. Great leaps in technological advancement are a characteristic of our times. New discoveries and new inventions have significantly improved the tools and the processes of our industries. Today, it is quite possible to achieve high quality products at minimal cost. This is the practical effect of technological advancement.

Nowhere is this truer than in the history of metalworking. We have far advanced from our ancient history of crude weapons and tool making to the present day fabrication of tiny precision metal products for a variety of modern uses. Zinc is one of the great discoveries of the modern world. It is one of the metals that have most affected people from all walks of life, and not only in technological terms.

Some forms of zinc are mixed in with our toothpaste, multivitamins, shampoos, deodorant, sunscreen, ointments and lotions. Not only is zinc present in all of these, and also in our cell phones and laptops, computers and kitchen appliances, toys and autos as miniature zinc parts, the metal is also naturally occurring in the human body. For zinc, like iron is an essential trace element. Without it in our bodies we cannot live.

In technology and industry, the uses of zinc are significant. To make miniature zinc parts for our gadgets of technology, first the metal is mined. Then it is melted, and pressure injected into a mold machine. Metal working companies make these mold machines for the manufacturing industry. Design technicians and engineers fashion high tech precision die mold tooling machines that are able to mass produce zinc into tiny, detailed parts. These parts are then used as machine components in the fields of aeronautics, communications, electrical and electronics, computer hardware, and consumer products. Zinc is the high yield low cost metal of choice for precision miniature zinc parts.

Techmire Zinc Cast Parts

Posted on 03/24/2009 by admin

Techmire Zinc Cast Parts. Techmire zinc parts casting machine has the capability to create multiple-slide die casting that creates economically small, complex zinc castings. Techmire zinc diecasting is the leader in fabrication and design of multiple-slide die casting machine for precision small die castings using zinc.

Currently Techmire is operational in more than thirty countries worldwide. It started in 1973 in Montreal, Canada. It has the expertise in all aspects of the zinc die casting process including building of dies and designing, auxiliary equipment selection and the initial and ongoing training service.

The largest Techmire die casting machine is the 88NTX with a dry-cycle speed of 2100 cycles/hour. It has a quick die-changing capability, which allows changeover in 15 minutes of two slide molds, based on the company’s statement. Their system is designed for large surface single-cavity production of area parts, or smaller components of multiple-cavity production.

Techmire zinc diecastings are among the companies that provide services in the metal working industry today. Techmire creates equipment out of die casting for large companies and outfits small custom. It operates in Canada, but it provides services in 30 countries worldwide. The Techmire zinc parts are the products of the machines designed and intended for zinc die-casting.

Techmire has introduced two different extra ordinary machines the NTX series and NT series equipment for zinc. NT series provides automation, with high precision and hot chamber machines that use advance technology called multiple slides. NTX series includes clamping systems, which use the latest in technology such as that handle extreme pressures, with higher capacity, and velocities.

Zinc Die Cast Tools

Posted on 03/22/2009 by admin

Zinc Die Cast Tools. In the metalworking industry, zinc die casting has become one of the highest grossing processes manufacturers can take advantage of. This process is known to be best used when a large amount of small or medium sized parts are needed. The resulting products from this process are of high quality, with a very smooth finish, good detail and the parts are consistent in terms of their dimensions. It has been said that the difference between each part from this process are so small that the need for post machining to correct the problem can be eliminated altogether.

Although ferrous metals can also be used in the process of zinc die casting, non ferrous materials are usually used instead of these. Examples of commonly used metals are tin, zinc, lead, aluminum and magnesium among other metals. Steel and iron are too strong and too hard to be used in zinc die casting; instead they are used to create one of the Zinc Die Cast Tools known as the mold.

The mold is where the molten metal is forced into under a high pressure environment. The molten metal enters every crevice of the mold and forms the part after they are machined by the next Zinc Die Cast Tools known as hot chambered machine and cold chambered machine.

Both hot chambered and cold chambered machines can be used in this process; the main difference is that although the former performs faster and better, cold chambered machines are used for metal alloys which the hot chambered machine cannot handle. This tool completes the whole process of zinc die casting.
