4) The mold production equipment that uses impeller blades to ?ing sand into a ?ask at a reasonably high velocity.
5) What type of equipment is used to pack sand around the pattern by lifting, dropping and squeezing?
6) What is the pattern material used by the evaporation mold process?
7)What material is used to make permanent molds?
Solution
4)
the mould production equipments are used in impeller blades preparation.
green sand,drag,cope, runner and raisers.
5)pack sand around the pattern using equipments are jolting machines,squeezing machine, sand slinger and ramp.
6)polymer spun materials are coated on the pattern material so it can resist the evaporation mold
7)permanent mould are reusable molds so we can prefer metals.
