Abstract
A method for manufacturing a molded surface fastener may include using, as a synthetic resin forming the molded surface fastener, a thermoplastic resin having a melt flow rate of 20 g/10 min or more and 60 g/10 min or less and a flexural modulus of 1000 MPa or more and 2300 MPa or less. Consequently, an engaging element in which a top end surface of an engaging head portion is flat, and at least a part of a back-side proximal end surface of the engaging head portion has an angle of 70° or more and 110° or less with respect to a height direction of the stem portion can be stably molded, and thus the molded surface fastener that has a high peel strength and a good texture can be obtained.
