Stretch blow moulder for PET

Technical features:

PREFORM-HEATING MODULE

• Horizontally positioned infrared lamps, grouped in various sections.
• Up to 8 infrared lamps for each section of the heating module.
• Possibility to set and modify the parameters of each lamp through the POSYC operator panel.
• Preform heating lengthwise differentiated and radially homogeneous.
• Heat-reflecting panels, made of composite material, mounted on the front and at the rear of the infra-red lamps to increase radiation intensity and, consequently, cut energy consumption.
• Mandrels chain pitch to 37 mm.
• Liquid-fed cooling system, in order to cool the protection ring preventing the preforms thread deformation during the heating process.
• Air-fed cooling system, in order to keep the heating module temperature constant and low enough.
• Modular design, standardized for all stretch blow-molders models.

STRETCH-BLOWING WHEEL

• Cam-controlled highly reliable technology.
• Standardized stretch-blowing stations for all blow-molders models, with a low dead volume thanks to high performance valves and optimized circuits.
• Liquid-fed cooling system, in order to keep the molds temperature constant.
• Air recovery system supplied as a standard equipment.
• Molds treated on the surface and made from a special aluminium alloy highly resistant to wear.
• Mold-holders made from an austempered iron casting highly resistant to mechanical stress.
• Motorized stretching rod to boost speed and enable a more flexible management of the stretching process.

AIR RECOVERY SYSTEM

• Two exhaust valves for each stretch-blowing station: the first one introduces the air into the air recovery system tank, the second one discharges the air that can not be recycled.
• Considerable reduction of the energy costs and 40% saving in the compressed air consumption; thanks to the recovery system, a part of the air in the blowing circuit is recovered and recycled for the pre-blowing circuit and for the machine service air. The pressure of the pre-blowing circuit is controlled by an electronic adjusting device. If the pre-blowing circuit or the service air circuit do not need the recycled air, it is possible to use it for the low-pressure circuit of other external systems.
• Use of eco-compatible, environment-friendly technology

ELECTRICAL PANEL AND MACHINE WIRING

• Electrical panel integrated in the heating module, thus reducing the machine overall dimensions; as a consequence, the final user has got larger space to install any optional equipment or additional accessories. Moreover, the machine structure is more compact and the access to it is easier, thanks to the elimination of the power cables (air or ground cables) that are generally used for the connection with the external electrical panels.
• Use of pre-assembled and pre-tested cables.
• Ethernet communication ring.
• SERCOS interface™ field bus.
