What is a blow type embryos extrusion forming mould

General forming process of hollow blow molding products, first by the extruder extrusion tube type embryo, then quickly put tubular type embryo in hollow blow molding mold, pressing into the compressed air blowing for insulating products.
tubular type embryos extrusion mould phyletic and various, sums up roughly divided into two kinds, one kind is continuous embryo type, another kind is the loading type embryo. Actual use morer now is the embryo mould material storage, but the mould is not easy to extrusion polyethylene material.
for example embryo in tube extrusion blow molding, extrusion machine for horizontal installation, commonly tubular type embryo from vertical extrusion die down. Tubular type embryos extrusion die for right feed circular aperture shape, and pipe, blown film, cable coating extrusion die similar, their common ground is the key component of mold core structure.
