***English subtitle still under review ****
Engineers, higher part and lower part
we will take the lower part
put mold on it
as same the mold (core) consists of two halves
we take the flat half
to be stable with us
*Engineers, stop talking!
First, we use a tool to fill our sand
around our mold In the tight places
When pouring in the sand it is important that all the sand gets packed in tightly to prevent any gaps in the mold
that will cause the molten metal to flow someplace it is not supposed to flow.
Then, we balance by a ruler
that's the first part
we can't add sand over sand
we must separate between them
whats this red thing?
Redbrick or anything can separate the sand
that's our pourer
a separator between the sand
you can use this mold for many times
you can get many of them by one model
that's our sprue?
yes, its the sprue
Its the second part
we must wet around our model before taking it off
to prevent sand cracking
this is core box for performing cavity inside
we can break this sand and rework, Engineer
Isn't clear?
The highest part
Do you know how the pattern performed?
Any Questions?
we should first put it in the furnace, to get rid of the water inside it
