Traditionally, plastic bottle molding machines can be divided into two
categories - those using the single-stage "hot preform" method & those using
the two-stage "cold preform" method. The single-stage method, from PET
granules to finished bottle, takes place in one machine. It is suitable for
small & medium scale production lines. ASB was a pioneer of the single-stage
method and remains a global leader in single-stage blow-molding machines.
The two-stage method uses two separate machines. The preform
is injection molded on the first, then reheated & blown in the second. This
method is suitable for both medium- and large-scale production.
Features of ASB machines
High quality bottles
Advanced molding using the "cool preform" method - hot preforms are
cooled to a uniform temperature for optimum bottle quality.
Rapid mold changeover
Quick, easy attachment of molds, combined with IC memory card storage of
different molding conditions, enables rapid mold changeover for increased
By re-designing both the machine & the molds, ASB has been able to halve
the machine size while maintaining the output of conventional machines.
In other words, the new machines can almost double bottle production
from a given space.
ASB has been able to decrease the number of mold parts and reduce
running costs by minimizing electricity consumption.
