Sheet metal prototype:The material of sheet metal prototype is the same as the material which
be rushed out by the model ,it is galvanized board.
The manufacturing process of prototype factory are as below:
Laser cutting(CNC punching machine cutting)-CNC bending forming-spot welding, blind revet,
boult)parts combination-surface treatment(painting)-finished product.
The appearance of the sheet metal parts is worse than the parts rushed out by the model.But
because don't have to develop the mould, it is a small batch products production method.
Plastic prototype:The material of the plastic prototype including ABS,PC,PMMA,PU.ABS is the
most common prototype material.PC,PMMA generally used in transparent parts,PU is generally
used in silicon mould small batch product material.ABS is mechanism squares, the density is
lower than those of injected ABS.After processing, internal molecular chain was cut fracture.
So the strength of the prototype made by ABS is low, easy to fracture ,cannot be used as
sales products.
The process of plastic prototype is CNC numerical control processing and silicon mold .
There is another process called laser rapid prototyping,the production speed is fast ,but
because of the precision of the finished product is poor, bad surface quality, it is not
recommended.
CNC means CNC milling machining cutting.The tools is generally the same as common
machining.The difference is milling material is ABS,PC,PMMA.3D data use numerical
machining software programming.Output to the CNC machine can work out what we
need semi-finished products.The semi-finished products after polishing, spray ,plating
process,to be final sample.It can equivalent to a formal products. It is the best way to
display and verify the appearance and function prototype .
The silicone mold is use silicone rubber to make the mold appearance.Use special
equipment to take out the silicone mold internal vacuum; then inject PU to the silicon
mold,put it into the high temperature oven for curing , fold and take out the sample.
The strength of the parts made by this kind of method is high , can be used as sales
product.Each silicone mould can be produced to hundreds sets.The quantity is too
many affect the precision decrease.It is a good way for short-term small batch products.
