Innovative solutions to boost Productivity

Stretch blow moulding machines of today reflect the high level of technical sophistication that manufacturers have achieved in response to the demand for a broad spectrum of containers with unique shapes.
 The Sacmi SBF range of blow moulding machines with functional elements is designed not only for sturdy use and easy maintenance, but above all, efficient from the point of view of the finished product. It uses an innovative elevation system with brushes; preform thermal conditioning oven: the oven of Sacmi SBF blow moulding machines is modular. Each module has its own ventilation and heat recovery system to make maximum use of the energy employed. The preform transport chucks rotate at adjustable speed, so that they decouple the two mechanisms that transport and rotate the preform. This feature gives added freedom in the creation and management of the preform's temperature profiles before blowing; blowing turntable: all Sacmi SBF blow moulding machines feature the 1B = 2b system, which means they allow the installation of a single mould for large bottles (up to 3300 ml) or, alternatively, of a double mould for small ones (from 200 ml to a maximum diameter of 75 mm).
 The blow moulding machine line has been ideal for all bottling production lines because it adjusts its production rate to that of the filling machine. The entry of the preforms into the mould and the exit of the bottles follow a route that is at a tangent to the original blowing circumference. The compressed air for blowing is controlled via an integrated block of pneumatic valves positioned next to each mould. This arrangement reduces the volume of "dead" air, minimises the delay in responding to pneu?matic pressure and saves a considerable amount of energy. The stretching block has 3 rods: the central one is used for the 1B configuration, whereas the two lateral ones are used in the 2b configuration. The switch in format from one configuration to the other can be made very quickly via a simple mechanical adjustment. The stretching rod is driven by a brushless electric motor. This innovative solution allows high stretching speeds to be attained, and these can be accurately controlled and easily programmed. It is thus possible to produce profiles that render the blow moulding of bottles – even of complex shape – simple, by decoupling the movement of the rod from the rotation of the turntable.
 The Sacmi SBF range of rotary stretch blow moulding machines represents high-end equipment able to produce 64,800 bottles per hour in the standard half-litre format. Each machine in the range, from the smallest model with 6 cavities to the biggest with 24, can switch with the greatest ease from moulding a large bottle with 1 cavity to moulding a small one with 2. In this way, it is possible to process twice as many small bottles, making full use of the moulding machine's capacity and productive potential, and of any filling machine to which it might be connected.

 Meeting demand for largecapacity containers
 In a iming for an expande d market reach in the Asia Pacific region, W. Amsler Equipment Inc. has launched a range of blow moulding machines that are capable of making high-quality bottles with precise, detailed engraving, as well as shapes that are difficult to produce, like flat ovals – ideal for companies that want strong branding or those with unique shapes. A privately-held Canadian company founded in 1994 by its current President and CEO, Werner Amsler, the company has earned a reputation for providing state-of-the-art, highly-efficient reheat stretch blow moulding machines and auxiliarAir Max
