With its new all-electric single-stage machines, Cypet Technologies said that PET processors now have the possibility to produce any size of PET bottles up to 20 liters and any size of PET jar up to 145 mm neck diameter. The company calls this a “world’s first” and says that there is no other all-electric single-state PET processing machine in the world that can produce jars with that diameter or bottles bigger than 1 liter.
Cypet recently introduced these two all-electric machine models, based on its proprietary single-stage PET processing technology. The company will be exhibiting at K 2013, in Hall 14, stand C58.
The Cypet single-stage process was originally implemented using servo-hydraulic injection technology, with three machine models covering all sizes of PET bottle and jar production. Now Cypet’s new all-electric machines will complement the three servo-hydraulic machine models that the company has on offer.
Servo-hydraulic technology uses a servo motor to drive the hydraulic pump, so that by controlling the motor speed, the pump delivers accurately the oil pressure and flow that the machine requires, without any waste of energy. In addition to saving an estimated 30% of electricity usage, this technology has a faster response time and therefore a higher movement repeatability and process consistency, compared with conventional hydraulic technologies, the company said.
However, compared to servo-hydraulic technology, the primary advantage of all-electric PET processing is cleanliness, eliminating the risk of contamination from hydraulic oil leaks. The company said additional benefits include savings in electricity consumption, the precision and repeatability of the process, the availability of parallel movements for saving cycle time and the lower maintenance requirements.
Cypet claims that its all-electric machines offer all these important benefits at an affordable investment cost, resulting in a minimal effect on the total production cost of the PET containers. As a result, PET processors can offer PET bottles and jars to their customers at practically the same price, but with the peace-of-mind benefits of all-electric container production.
The company touts that its all-electric machines retain the flexibility that its servo-hydraulic machines offer, with respect to the very wide range of sizes of PET containers that can be produced on a single machine model, by changing the molds.
