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.
