Indofood Corp has conveyor system is used for carry away wheat flour
from bottom site to hopper on top of food processing machine.Conveyor
has some bucket rotate on railway system. Material made of plastic
PA6 (nylon) or PP.
They need bucket replacement and they give me sample.Before that they
already search the available plastic maker to make it.Many maker give a
quotation US$ 10,000.00-20,000.00 for 400x700x350mm mold size
with 1 cavity investment and US$ 8.00 for production cost of that part.
I just give price 40% from that above price for mold and US$ 7.00 for
production cost. Because they just need only 200pcs of bucket. So the
mold doesn't have to use mold steel and the tolerance isn't too precisely.
Deal!
I take the sample to reverse engineering it just with ruler and
pocket caliper. Go to mold design process within many consideration,
machine ability, dead line,cost and handling.Our machine ability only
400x600mm process stroke.Whoala! design ok get ready to machine
process. To speed up i divide the process one part on our machine one
part to subcontractor.
Subcon A(Stalion)give a quotation US$ 600.
Subcon B(Coppal) give US$ 2000.
I give it to Stalion.
After mold is finish we deliver to AA Plastic Corp to make plastic part
using injection machine 550Ton.And then i send that part to Indofood.
They happy we are happy too.
