The endless upper and lower mold block(1)(1') is close to one or two sides of the manifold with inner hot runners. The slide fastener stringer is produced by installing the element forming cavity on the connecting face of the upper and lower mold blocks and inserting molten material through the hot runner into the mold block under pressure. Fastener stringer(S) is endlessly shifted by cooling the molten material of the former mold block and eliminating the polymeric mold block in turn.
