Company officials report that Siapi srl is the first blow molding machinery maker to beat the mark of 28,000 1-liter PET bottles per hour produced by a two-stage linear blow molder.
Siapi said competitors that make rotary machines launched the challenge years ago to blow 12,000 one-and-a-half liter PET bottles. But the Siapi officials claim their design has been the volume leader for more than 22 years.
The new line of SDxx two-stage machines give high speed for a full range of PET containers. The two xx’s after the SD indicate the number of cavities, from 6 to 20, that are arranged on two parallel presses that run in synchronized fashion.
One feature is called the star-type loading system, which sorts heated preforms going into the two presses. Also, automation runs and controls the simple machinery movements.
The range of two-stage linear blow molding machines comes in eight models: to produce containers of 9-liters at a rate of 7,200 an hour; 4-liters at 10,600 an hour, 3-liters at 12,800, 2-liters at 15,200 and 1-liter at 22,800.
Siapi is based in San Vendemiano, Italy. Siapi America Inc. is in Norcross, Ga.
