Wood character needed

1.material should be cheap and easy to work with2.easy to burn3.reusable, environmentally-frendly,without poisonous smoke4.easy to carry5.it should be cylindrial(a cylinder or a rectangular solid) and have the suitable size to make manufacturing easily

StackStickProjectHistory of the conception

Final outcome

We choose a piece of wood and chips from a factory far away with the following characteristics:

• 150RMB(wood and chip totally)• pine • a ractangular solid (150*150*1000)mm

• the wood is the best one we can find to satisfy the requirement mentioned above and coordinate the conflicts between different characteristics


History of conception 1/2

• The main idea was to follow our • 3D model plan

• Needed tool would be a lathe with a four-jaw chuck

• On-campus workshop only provides only a three-jaw chuck• Impossible to produce the prototype in the workshop

Block of wood

Four jaw chuck


History of conception 2/2

• Factory-like workshop on campus

• Prototype was impossible to make on a lathe.

• Many different methods for prototyping – but none for wooden produtcs

• It was possible to make a mould with rapid prototyping – too costy and late delivery

Recipe

This is a dangerous production process. The product can easily catch fire.

Attention:

Don't do this at home!


Recipe - Material

- Take candles and smash them

- Mix it with smashed wood

- Shake it


Recipe – Final product

- Take two funnels, one big, one small

- Cut the smaller one as shown on the picture

- Put a little bit of material in a plastic bag. Put everything in the bigger funnel.

- Put a plastic bag on the small funnel and put it inside the big one.

Take plastic that can handle high temperature!



- Finish fulfilling it with material and put it on a cup half filled with water.

- Put it two times 2 minutes in the microwave.

- Put it straight away in the freezer

- Repeat the same operation with a cylinder shape.



- Stick both part together with hot wax.


Final product

• looks very easy• took several weeks of research

important factors:• exact mixture of paraffin and sawdust• time and temperature for the sintering process• time and temperature for the cool-down process


Final product

Material Cost:Paraffin: 2 YuanSawdust: 0.5 YuanAdditional Items: 0.6 Yuan

3.1 Yuan

Burning Skills• testobjects (10x10mm) could beset on fire like a candle• objects burned for at least 8:26 minutes• no additional components added• very solid and light strukture• safe handling (no explosions possible)• very cheap


Final product

• production in 2 separate steps

Hat + Tube

• both parts “glued” together

• finaly drilling the hole into the hat


Conclusion

MORE RESEARCH ON THE MIXTURE IS NEEDED


Conclusion

• Prototype burns well• Cheap• Safe

• Standarization for the mixture is needed• Different material needs to be tested• Process of manufacturing needs to be standarized

Project was a succes!

CONPRO

Future Plans:• Finalized chill-mould for perfect production• Different product sizes of the stack stick• Test run with other shapes• Collaboration with other products, i.e. one way BBQ


Thank you very much for your attention!
