3D Printing For Sand Casting In Egypt
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?
- 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.
How to Start Using 3D printing in your factory Now in Egypt
- 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.
- Send the Model to firstname.lastname@example.org and get it done and sent to your factory in Egypt.
- 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.
- Mount the casting pattern and parting line elements on a wooden plate. The parting–line elements will be fixed in place to the plate.
- Apply a surface release agent on the 3D-printed master pattern.
- 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.
- Use the mold: Pour the molten metal in the cavity. Once it cools, it can be removed and finished.
