HSO Series

The HSO Series machines from ASB are Two-Step reheat blow  molding 
machines designed to produce heat  stabilized  PET  bottles  using  the
Double Blow method. There are six steps in the process:

1 Preform Reheat Conditioning

    The preform is heated to the optimal temperature for blowing.

2 Primary Blow Molding

    The hot preform is stretch blown in the primary mold to form an
    oversize bottle.

3 Primary Heat Processing

    Heat setting is done by a direct contact method.

4 Secondary Heat Processing

    The bottle is indirectly heated in an oven to  induce  stress   relaxation and 
    promote crystal growth.

5 Final Blow Molding

    The shrunken and a slightly deformed bottle is blow molded to the products
    final shape.

6 Bottle Ejecting

    The finished bottle is ejected from the machine.


Characteristics

This Two-Step  reheat   blow   molding    machine    produces   heat-resistant 
containers. Preforms  go through   carefully   controlled   heating   &   blowing
processes, consisting of reheating, primary blow, primary  heating,   secondary
heating, and final blow. All the specifications demanded   by  the  industry  for 
heat-resistant PET containers are met or excelled. With a shorter  cycle  time, 
the  HSO  Series  has  a  compact  design  that  revolutionizes  heat-resistant
bottle production systems. When used together with the PM Series of preform 
molding machines and the CM Series neck  crystallization machines, the  result 
is an integrated production line that  elivers  defect-free,  cost-effective  high 
heat-resistant containers.
