B- SPLIT PATTERNS AND CASTING DEFECTS Flashcards
What solves misalignment/MISMATCH issues for split patters by passing LOCKING PINS through holes?
MATCH PATTERNS/PLATES
What creates passageways, while denying access to molten metal?
CORES
What generates indentations in the cavity wall for the core and lets the workers know where to place core?
CORE PRINTS
What supports one end of the core until it becomes fully surrounded by metal?
CHAPLET
What is the solution to a COLD SHUT?
DYE PENETRANT
What does NDT stand for?
Non Destructive Testing
What are CORES made out of?
Composite material consisting of SAND bonded together with THERMOSETTING RESIN
What are gas filled areas inside the metal part?
VOIDS
What is the defect created when SAND and SLAG mix with the molten metal in the cavity?
INCLUSIONS
What is the defect when extra metal is present on the final part?
WASH/CUT
What is the defect when metal cools and solidifies before filling the mold cavity?
MISRUN
What flaw results in porosity or cracking due to temperature gradients within a cooling part?
HOT TEARS
What are the types of SURFACE DEFECTS?
