|Die casting is the process by which molten metal under high pressure is forced into steel molds so as to create specific shapes after the metal cools. Die casting is used to create any number of household objects , from toys to bathroom faucets, as well as any number of much larger metal fixtures.
The goals in designing die cast aluminum parts should be low cost-per-part and maximum production in cast units. Computer aided design software (CAD) will contribute directly to these goals. A number of guidelines have been developed within the CAD and die casting community to make these goals more attainable.
Aluminum casting is the process of pouring molten aluminum into a mold to create a part of a desired shape. Casting is used in many different industries to create a wide range of parts. Aluminum is a lightweight yet strong metal with excellent corrosion resistance. The amateur hobbyist can create aluminum castings with the right tools, instructions and safety precautions.
Die Cast Methods
The hot chamber: Hot-chamber machines, also known as gooseneck machines, rely upon a pool of molten metal to feed the chamber methods: These are used when the casting alloy cannot be used in hot-chamber machines; these include aluminium, zinc alloys with a large composition of aluminium, magnesium and copper. The processes for these machines start with melting the metal in a separate furnace.
Both utilize injection systems, but in different ways. The hot system is used for metals with low melting points such zinc, copper and lead. The injection system itself is immersed in a bath of molten metal where it then fills with the liquefied metal. The cold chamber method is used for metals with higher melting points like aluminium. A manual or automatic ladle pours the molten metal into a cylindrical sleeve and is then sealed under pressure to cool.
At Aluminium Die Casting Manufacturer Company Endurance makes aluminium die castings using both un-questionable and low stress strategy. Endurance uses the un- questionable aluminium die launching strategy mainly for two wheelers, three wheelers and four wheelers. At Endurance, all items are designed and tested with uncompromising quality examining. The elements during production go through extensive quality checks at each stage which ensure that quality expectations specified. It is a continuous practice of Endurance to set quality standards in the industry with its quality items which will eventually mix its goal to pay attention to a successful and maintainable growth structure.

PIM Team Case Study: Creating Text Effects With PHP and GD
See how you can create graphic effects on text with PHP and GD - drop shadows, arcs, fonts and colors.
A-tec Signs and Sraphics Inc. launched a web site with the idea to sell decals online. To achieve better customers ineterest the website had to integrate online decal builder. The company is offering also decals for vehicles which brought some specific requirements to the builder like having the decal text turning arround 4 types of arcs.
- Provide users with preview area
- Allow visitors to choose font and color
- Allow adding drop shadow and selecting drop shadow color
- Allow turning the text into arcs
- Real Time calculating
Because of the need for increasing customers interest we had to think about not for perfect math formulas when showing the graphs in the preview area, but for the people who will look at them.
As we will reaveal below, there were few problems going arround human appreceptions for something 'perfectly smooth' and the matchematical perfect figures.
We were going to extensively use PHP GD library for the text effects. It provided easy changing of fonts and colors, adding drop shawdows and rotating the texts.
The main problem in this site was to create 4 types of arcs so when the user selects one of them the text is created arround imaginary arc (like in the vector graphical softwares). We were going to study Bezie's formulas and create these arcs with its help.
PIM Team Bulgaria had the task to build the full functional online decals builder with the following features:
- Decal background
Some users were supposed to have their decals placed on colored background. We had to allow the preview area to be painted in a selected background. First we created the image in temp folder:
the name of destination image
imagefilledrectangle ( $im, 0, 0, 590, 60, $colors[$_POST['bcolors']]);
$colors array contains the available color which are stored by the administrator in the database.
Thus, when the visitor selects a background it is passed as parametter to imagefilledrectangle function.
- Font selection
Users should be able to select fonts for their future decals. Knowing that we can't consider all the fonts will be available on all visitor's computers we had to upload them on the web server directory.
We allowed the admin to manag.
