Production technique medium size lot

In this video you can see the production technique for the medium size batch. It may also be possible for the large production technique.

The metal sheets are first ponched in the places they need holes. After this the plate is bended in to the right form. In the final step the parts got painted. This as a protection layer for the metal against corrosion.

The connection system that we want to use is on the same principalµµ as in the DIY lasercut prototype.

There are crosses made in the plate but without a larger center. On the sketch there is a U shape with an up and down pointing part. This can slide in the cross shape. These will be attached on to an elastic fabric. where one side of the fabric is attached with a loop to the 'U' shape and the other side is sandwiched between the 'U' shape and the plate.

DIY product ok

Still think about the handel unit. think about assymetic holes and a smaller handle part. Possible to make it solid?

Important note: try to do more consults. Still a lot of work to do.

Material choise: think about existing toolboxes (wood, steel, plastic)

Medium batch: use alluminium or steel. Bend the sheet in the right form.
Composit is difficult with the inserts etc.

Large batch: finish CAD design. What with the handle unit? Strong enough?
Maybe better an extrusion profile.

Large batch

As discussed in the middle batch production we have the option to use extrusion as a production technique.

with the advantages of the low price, speed, quality and electronic isolation. of all the parts of the toolbox.

For the large production we would like to use a new production method: injection molding.

The main reason for choosing injection molding is because it will be faster. And the parts will all be from the same isolated material. Is is still important that the material is strong enough for all the tools.


There are different kinds of injection molding and a lot of different materials to use in the injection molding. The best material will be selected with the CES.

Also for our CAD simulation we have to make sure we use some rules. There can not be any sharp edges. The wall thickness depends on the material and has to be the same everywere. To connect the different parts we will use a snap connection. 

 

The material used is ABS.
