casting
The flask is comprised of THESE two main parts.
What is the COPE and DRAG?
Powder consolidation is more versatile in comparison to casting for THESE reasons. (List at least 2)
What are:
Making porous parts
Easier to make a large quantity of small items
Can create exact shape without extra to cut off
THIS temperature marks the difference between brazing and soldering
What is 450 DEGREES CELCIUS?
Processes such as drilling, milling, and grinding are examples of THIS type of removal.
What is MACHINING?
Deformation is unique as a processing technique for THIS reason.
What is NOT CREATING ANY NEW MATERIAL OR PRODUCT?
THIS part on the inside of the flask ensures that the mold cavity is fully filled with material by storing extra liquid which then flows in once the sprue is clogged.
What is the RISER?
Powders can be made by THESE three processes (explain them)
What are MECHANICAL, CHEMICAL, and PHYSICAL PROCESSES?
When welding, THESE three regions are identified.
What are the FUSION ZONE, HEAT AFFECTED ZONE, and UNAFFECTED MATERIALS?
Etching can be accomplished by wet etching with acid or dry etching in THESE two methods.
What are REACTIVE ION ETCHING and VAPOR PHASE ETCHING?
Rolling a material creates internal stress and an unstable form for the crystal grains. In post-manufacturing, THIS process stabilizes it.
What is RECRYSTALLIZATION (through heat treatment)?
THESE two examples of single-use molds produce more waste material in comparison to THIS multiple-use mold.
What are SAND MOLDS, CERAMIC MOLDS, and DIE CAST MOLDS?
Powder consolidation is made of THIS 5 step process with an optional 6th. (List the steps)
What is:
Powder production, blending, compacting, pre-sintering, sintering, and (optional) secondary operations
In brazing and soldering, metal fills the gap between the two materials by THIS phenomenon.
What is CAPILLARY ACTION?
Water jet removal is beneficial for THESE reasons.
What are HIGH ACCURACY and LOW MATERIAL WASTE?
In THIS process, a material is held with pressure on the sides and a ram punches the shape into the plane.
What is DEEP DRAWING?
In casting, slag can appear and affect product quality. THESE three solutions are ways to minimize this occurrence.
What are:
LOWERING SUPERHEAT
FILTERING GATING SYSTEM
EXTENDING THE RUNNER
What is PREVENTING CRACKING?
Diffusion bonding describes a the process of heating, but not melting, the joining materials to THIS percentage of melting temperature, allowing atoms to jump between them and giving the joined area THIS property.
What is 60-70% and STRONGER THAN INDIVIDUAL MATERIALS?
An inverse of electric plating, THIS process involves removing a layer of coating from the product.
What is ELECTRO-POLISHING?
In THIS process, material is pulled through a die to create a piece with a smaller diameter.
What is WIRE DRAWING?
Of THESE three types of furnaces, THIS one is the most expensive. (List three melting furnaces, the most expensive, and how it works)
What are:
TRADITIONAL FURNACE, INDUCTION FURNACE, and ARC-MELTING FURNACE?
most expensive: ARC-MELTING FURNACE
The physical process of powder production contains THESE two steps, creating spherical powder
What are SPRAYING MOLTEN MATERIAL and SPRAYING ATOMIZING GAS/WATER?
Between the methods of joining, THESE two need to be cleaned before joining, THIS one works better with an impure surface, and THIS one inherently cleans itself in the process.
What are:
BRAZING/SOLDERING AND DIFFUSION BONDING
ADHESIVE BONDING
FUSION WELDING?
Various joining processes include heating or even melting material to join two parts. They aren’t included in casting for THESE reasons.
What are NOT COMPLETELY MELTING and NOT INCLUDING A MOLD?
During extrusion, materials are heated, not melted, and forced through a die with a ram exerting pressure. This works better for materials with THIS property.
What is DUCTILITY?
