Pressure die casting is recognized as a process in which a metal is treated and melted under high pressure and turned into steel dies. A bit of information about the die casting will be useful for you if you are in the related business or provide products like reflector, end shield hub type, levers, case upper etc. An interesting part is that it has a high level dimensional accuracy with a smooth surface and hence, these die castings made with high pressure does not require much machining. The machining is only used for removing the flash on the edges and drilling and tapping of the big and small holes.

You may be interested to know about the difference in high and low quality of high pressure die casting. A high quality high pressure casting implies that the right amount of casting tools and right amount of pressure will create around thousands of parts of high pressure die casting. On the other hand, low quality parts can be made amounting to hundreds of die casting parts at a time.

The tools form an important aspect of the pressure die casting. High amount of accuracy is required while building it so that the functions are performed properly. These are basically made from steel is that is hardened to tolerate high temperature and very low/ high pressures. This is mainly a one-time expense for you as any other capital cost. Once the high pressure casting tool is made, it will cost very less to manufacture other die casting parts. The competency to produce accurate and reliable tools at a lower cost depends on the manufacturer’s ability.

The process of die casting is summarized into four stages:

• Preparing Die – These are mainly prepared by spraying up the mold cavity with some lubricants for controlling the temperature and removing casting
• Filling – the dies are closed and then the metal is injected into the dies at high pressure. The high pressure conditions are maintained till the next stage
• Ejection – The die is opened and ejector pins are used for ejecting the shots
• Shakeout – the scrap is separated from the shot by the process of sawing and grinding.

An important step after the shakeout involves inspection for defects which exist in the form of mis-runs and cold shuts. While using the lubricants, one should also be aware of the environmental and safety conce
s. For this reason, water based lubricants are used. Water can be treated properly and all the minerals can be removed from it which is generally not possible with the solvent based lubricants.

One of the major disadvantages of the process of die casting is the high capital costs involved. One way to make it more economical is to produce it in large quantity. The cost – benefit analysis will make it easy to weigh the benefits against the costs. With high pressure die casting, there is better dimensional accuracy, smooth surface, less dependence on machining, higher production and so on.
