1.	Runners, gates and risers are attached to the pattern to __________(a) Provide ease of cooling(b) Provide feed to the molten material(c) Provide design to the casting(d) Enhance the finishing of the castingI got this question in class test.Question is from Functions of a Pattern in division Pattern and Pattern Making of Casting-Forming-Welding I
Answer» Right option is (b) PROVIDE feed to the molten material The explanation is: These external ELEMENTS are added to the pattern or mould CAVITY to enhance the flow of molten metal,hence, to enhance the casting PROCESS.
