MOLDING AND CASTING


For this task in individual form we will have to design a mold of 3D it is schemed in any material that serves us as such, which will use it to do pieces in any type of mouldable material.

I want to do a lattice in ceramics, for what I need a mold. I begin with my sketches:











Start by using different geometries, we start giving him form using CorelDraw


Parameters

Obtaining the following figure

With the design obtained of CorelDraw, we cut some samples in styrene of 2.0 mm

Pieces of styrene

With the file in DXF, we begin to be employed at Rhino, to make the mold

After five hours working I obtain: 

From Rhino Cam I start preparing to scheme myself, since it is the software compatible with the router AXYZ that it will use.

A tool will use ball head of 5/16 " of diameter, to machinate in 3D

It will make it with the following parameters of court, since it will use MDF

The simulation in RhinoCam

Machinating as comment on it before in a router AXYZ

I had to give him some retouches, since you re-recover in the walls, to smooth them well

This one is the mold, I list to empty and to have our pieces in ceramics.

I continue with the process, beginning preparing the ceramics, the important and fundamental thing for a good boiling and without disadvantages it is: That the realized pieces are done by the clay kneaded well to prevent it from containing air bubbles and exploit in the oven or a piece skips them.


I refill the mold with the kneaded well ceramics

Here this one my pieces ready to dry off for 24 hours, in order that they do not break in the oven, have to dry off well and very slowly to avoid that for the force of the contraction that takes place in the dried one, fisure the piece.

Already past 24 hours, I use an electrical oven it marks Cress

I have to programme the oven to a pace of raise of 150 ° per hour and in the possible thing not bake in less than 6 hours (the ideal thing is between 6 at 8 hours and in agreement to the size and the load of pieces that has the oven). Between 500 °/600 ° are the critical moments of the clay because there - the changes take place. 


In the first attempt they broke, possibly and I think that sure mas is, they were not totally deshumidifiers for what they exploded

I returned to do another attempt, the good thing was that we had a week of rest and I had the sufficient time.

Already my baked pieces and with more time of dried

Actually this one would be the idea of the union of lattice with lattice, it is by means of spike that it fits into another piece, in order that on having placed the following one it takes the wished order but … it would have to do the a bit more detailed process.



The final project for a front
