ABSTRACT:
A molding machine (1) may include first and second dies (13, 23) arranged and constructed to be closed and opened, and first and second trimming members (17, 27) arranged and constructed to engage with each other after the first and second dies are closed. When the first and second dies (13, 23) are closed, a resin based sheet material (S′) is pressed so as to form a molded material (S). When the first and second trimming members (17, 27) engage with each other, the molded material (S) is circumferentially trimmed so as to produce a molded article (Sa) and a waste strip (Sb).
