In horizontally parted moulds, a draft is required for vertical as well as for horizontal surfaces of a pattern.(a) True(b) FalseI have been asked this question in an international level competition.Question is from Pattern Fillets in section Pattern and Pattern Making of Casting-Forming-Welding I
Answer» The correct option is (b) False The explanation is: The draft angle required on the pat¬tern mainly DEPENDS on the moulding process and the depth of pattern in the mould. ESPECIALLY in horizontally PARTED moulds, only the vertical surfaces require a draft. HORIZONTAL surfaces separate the pattern from the mould automatically during pattern removal.
