Expensive Lesson ~ Sand Casting
That was a case of “a principle applies different definitions,” hence it was born even we didn’t have any expectations.
As I had a chance to take a closer look at this Aluminum match-plate pattern, I decided to turn this pricey spent into an expensive lesson I learned.
Here we go,
Above is match-plate pattern, it is split into 2 parts, cope side and drag side. These 2 sides are attached to a plate in opposite way and perfectly positioned to each other.
How does it work? (again, from Wikipedia)
- Place a pattern in sand to create a mold.
- Incorporate the pattern and sand in a gating system.
- Remove the pattern.
- Fill the mold cavity with molten metal.
- Allow the metal to cool.
- Break away the sand mold and remove the casting.
