Compared with the injection mold, the extrusion blow molding has the following characteristics:

1 .the blow moulds are usually only moulds;

2. The blow up pressure of blow mould cavity is small, generally 0.2 to 1.0MPa.

3.The blow with general cavity without hardening treatment, unless required long-term production;

4. Blow molding cavity, the parison is formed by expansion, which can reduce the flow mark and the wear of the die and die.
