Most people think that zinc die casting tooling is all about the shaping of zinc metal alloys. Zinc die casting tooling is used to manufacture zinc parts. The truth is there is more to the zinc die casting tooling manufacturing process than meets the eye.
Die casting zinc tooling made by Die Casting Zinc company, www.diecastingzinc.com aside from shaping zinc alloy is also the production process which treats the metal alloy itself so that it will show the qualities known to zinc parts. The die-casting tooling process also allows the die casting company to produce high yields of die castings.
There are important factors involved in the zinc die casting tooling process: the molds and the water line system.
The dies, consist of two parts called the cover and the ejector, are responsible in the creating and shaping process of zinc die cast parts. These two dies halves hold the shape and size that the molten zinc alloy will contour when it is injected in the hot or cold chamber machines. These two die halves meet in the parting line to produce a part.
The cover die or the fixed die half has a hole where the molten metal will flow. It is usually secured to the front part of the casting machine. The ejector die half contains pins pushed by an ejector plate. It is this driving force, which gives die cast parts the different shapes they have.
Some companies use different dies in the zinc die cast components production. There are dies that contain mobile slides, which are sections that produce threads or holes. These are necessary when the finished product must contain a specific shape customized by the company. Examples of these are miniature cars that are sold as toys in the market.
There are also dies used based on their capacity to produce parts. The single cavity die is used to produce a single zinc part. The multiple cavity die is used when it is necessary to produce many parts in a single go. The parts produced by this tooling are identical to each other. Another tool used is the unit die, one which mold base produces several different parts. Combination dies are used when companies have to manufacture components that can be assembled into a single unit.
The fluid line system is responsible in the overall cooling treatment of the zinc die cast tools. The fluid line system is fed with water, during the metal alloy’s compression, or the part where the two dies meet in the parting line to create the zinc alloy’s shape. The water fed by the system lubricates and cools the zinc alloy enabling it to finally take its final form.
The tooling system also uses gas escape vents, or the holes where the gas, a by-product of the zinc die cast production can escape. It is important to let that gas escape during the compression of the process, or gas bubbles, an indicator of high porosity in metals will occur. These metal gas bubbles indicate that the metal will not be able to withstand tensional stresses.
Zinc die cast tooling is not just about shapes and sizes of zinc parts. It is also responsible in strengthening the parts making them safer and more convenient to use.
