New stretch blow molder/filler monoblock offers extensive advantages

Since its launch to the market, countless beverage companies have been convinced by KHS’ InnoPET BloFill stretch blow molder/filler monoblock system. For in addition to specifically saving on the cost of an air conveyor and decreasing the space requirements by eliminating the need for an air conveying segment, the system also has the advantage of gentler PET bottle handling.

A redesigned KHS stretch blow molder/filler monoblock has recently been brought onto the market that now boasts even more extensive advantages in addition to those it already offers. The many positive aspects of the new monoblock concept lie in the fact that here the new generation of KHS Corpoplast InnoPET Blomax Series IV stretch blow molders is being implemented. Another plus pertains to the new modular monoblock concept.

The new InnoPET BloFill stretch blow molder/filler monoblock is capable of processing a wide range of plastic bottle sizes and shapes, with PET bottles holding anything from 120 ml to 3 liters. The monoblock setup is able to process up to 72,000 PET bottles per hour, with typical efficiency levels exceeding 96 percent.

The first point of optimization within the new monoblock system is directly downstream of the stretch blow molding process. Implementing the new generation of KHS Corpoplast InnoPET Blomax Series IV stretch blow molders is yet another advantage of the new monoblock concept. InnoPET Blomax Series IV machines are equipped with a new heater based on a heating technology that nearly halves the time required to heat preforms versus the InnoPET Blomax Series III system. This has the advantage that the heater segment only takes up half as much space as the previous heater and only half the number of the preforms are inside the heater element which means that only half as many preforms need to be channeled out if an emergency stop is triggered within the monoblock as opposed to the previous setup.

Another key factor is that the stretching processes in the blow stations are controlled by servo motors. The stretch speed is now independent of the machine speed, which facilitates adapting different bottle sizes to the filler.
