3. 2.1 What is your primary process? Why
did you choose this process?
Primary process is Wire drawing because
we want to create a structure for each part.
Before increase the strength.
4. • What is your secondary process? Why
did you choose this process?
Similar hand lay-up process. It is
The resin applied by hand. Wire frame covered with
a cloth before applying resin stents to increase the
strength.
5. • What is your tertiary process? Why did you
choose this process?
Circuit process because the speaker must be
connected to a battery source.
The assembly process by gluing.
And painting for decorate.
Because it is the process to assemble a complete piece
of work.
7. With your selected material, how is
your material compatible with
product geometry and manufacturing
processes?
The resin material is selected which this resin is
a polymer that is used to increase the
stiffness of the structure of Labour.
By making a wire frame, then use a shawl.
Next, use the resin coating the surface.
It is easy to make different shapes.
8. What is the normal applied load
to the material? Can your
material take such load?
Because our products without a key chain.
It was a impact for some time. So
these materials are strong enough. Because
plastic resins properties have high
strength. Impact resistance as well.When it
can’t
changes shape when it hardens and forms a s
hape.
9. What is the normal ambient
conditions to your material?
• We do not produce material for a
particular load.It usually only hanging bag.
But what should be a circuit which is to
be fully engaged with the material for
durability.
10. With your selected manufacturing
process, how is your process
compatible with the product
geometry?
The selection process for a piece of the
curve. The shape depends on
the bending wire into different shapes.
11. - Show a calculation to obtain the total
cost per part of your product
12. • Total manufacturing cost (TMC) = Material (M) +
Tooling (T) + Processing (P)
• Material (M)
•
• cw = material cost per unit weight
• wp = weight of finished part
• ww= weight of wasted material, scrap
• a = ratio of wasted material weight / finished weight
• = ww / wp
• Then the material cost per part, cM is
14. a= Ww/Wp=0.01kg/0.25=0.04
cM = (100 bath/kg)x(0.25kg/part)x(1+0.04)
= 26 bath/part (head and body)
Steel wire head 2 bath
Body 10 bath
Legs 3 bath total =15
15. So Material (M) cost= 26+15= 41 bath
And Other devices
Loudspeaker 50 bath
Flashlight 30 bath
Battery 20 bath
Total manufacturing cost (TMC) =
41+50+30+20 bath= 141 bath
