3D Printing For Sand Casting In Egypt

3D printing has long been considered a tool to quickly design and make one-off prototypes. Now this technology is available in Egypt by Etba3ly 3D. We at Etba3ly 3D are trying to make 3D printing  more accessible, more affordable and more capable, it is beginning to redefine the way we think about manufacturing almost anything - and the way we run our businesses in Egypt .

3D Printing For Sand Casting In Egypt

Sand casting patterns can be 3D printed with Our FDM Technology for substantial savings in cost, labor and time, ultimately speeding new product development.

There is no need to pay a lot of money to make pasterns abroad, or wait for labor to finish your parts.

What is Sand Casting?

​The sand casting process uses a mold made by pressing a pattern into a sand mixture. The pattern leaves a cavity into which molten metal is poured. This process works well for low–volume production. With automated equipment, it can be efficient for high–volume production. Three common types of sand casting patterns are:

• Loose patterns, which simply replicate the cast piece; patterns are not connected to other patterns or mounted on a plate.
• Cope and drag patterns, or split patterns, are like loose patterns with a gating system added and a split along the parting line.
• Matchplates are similar to cope and drag patterns except the cope and drag sides are combined into a single piece.

Producing sand molds and cast metal parts is relatively straightforward and suitable for automated methods that can reduce cycle time and labor. However, fabricating the patterns in Egypt is often difficult, time-consuming and expensive. The most common approach in Egypt is to sculpture the patterns. The biggest problems with this approach are the high cost and lengthy lead time. You have to wait for workers to finish your pattern. The potential for problems, such as incorrect shrink compensation and design flaws, means the initial pattern often must be redone, which adds to the expense and lead time. Now you can make your pattern in a matter of hours using 3D printing technology in Egypt.

How to Start Using 3D printing in your factory Now in Egypt

1. Make a 3D model.  Design a master that will maximize the capabilities of FDM. Print the master, which will become the pattern, with the best build parameters for the desired surface finish and strength.
2. Send the Model to contact@etba3ly3d.com and get it done and sent to your factory in Egypt.
3. Accommodate parting: Mount the pattern on parting-line elements (which can be FDM or inkjet 3D-printed fixtures). The parting line helps avoid issues with undercuts.
4. Mount the casting pattern and parting line elements on a wooden plate. The parting–line elements will be fixed in place to the plate.
5. Apply a surface release agent on the 3D-printed master pattern.
6. Create the mold: Pour sand around the pattern and parting line element and remove the pattern. A cavity appears in the shape of the pattern, the upper half forming the cope and the lower half forming the drag.
7. Use the mold: Pour the molten metal in the cavity. Once it cools, it can be removed and finished.
