Syntec 6000 Linear Blow Molding Machine

Syntec 6000 is our newest, innovative yet inexpensive beverage industry blow molding unit with a capacity of 6000 bottles/hour (1,5l). Our machines are proudly manufactured in Germany. We produce this highly reliable machine according to the highest European quality standards.


 Syntec has been completely re-designed from scratch based on our experience with our previous lines of PET equipment. An optimized computer-control system drives the blow molding process to deliver constant high quality bottles while keeping scrap and overall costs low.
including :
- Automatic preform feed system
- Preform positioning device,
- Preform transport conveyor
- Heating installation
- Blow moulding assembly

- Closing assembly for four-cavities moulds

- Automatic collection of produced bottles (feeds directly to conveyor or to a container)

- Operator-friendly touch-screen PLC control panel with production data acquisition connectivity


Syntec 6000 is a machine built with many unique features that were addressed due to years of experience with PET blowing machines in the market. In almost every section we could improve the reliability and efficiency of our machine to bring you our next generation blow molding machine.


Highest Quality – Best Parts, Quality Manufacturing


Syntec is a linear stretch-blow molding machine for production of PET bottles (containers) from preform blanks. World standard up-to-date technical solutions have been used in the machine, with elements from the following manufacturers: Festo, Bosch-Rexroth, SMC, B@R Automation, Herion, Moeller, Danfoss, Eugen-Seitz, Adphos. In the core blowing process, a highest quality set of valves is used made by a Swiss company Eugen Seitz. The machine is manufactured in Germany by experienced and highly-qualified personnel, resulting in a proven, high quality solution.

Patented Closure Technology – For Smooth Bottles

Mould closure is performed by a patented mechanical-pneumatic system. When mould is closed, the system is blocked by an air cushion. The mould blowing air is simultaneously supplied to the closure system and therefore the mould closing force is always applied at a right moment. At the time of mould blowing, the system is fully closed and there are no slits on the bottle sides, characteristic of other closing systems. Even after many years of use, no mould deflection occurs during mould blowing. Replacement of two double-cavity blow moulds may be very quickly performed by only one person. The high quality sealing system (made by Merkel) and the Rexroth Star linear bearing system ensure long lasting failure-free operation.


Innovative Process For Reliable and Fast Strechting


The stretching rods are displaced by a servomotor-based electric system with its own mechanical subsystem. Stretching rods are guided by the Rexroth Star linear bearings. Such a solution gives the following benefits:

-Considerably greater stretching speed,
-Great repeatability of the stretching process,

- Stretching rods are not separately regulated - when a mould is changed the stretching rod position is automatically adjusted,

- The stretching process speed is adjustable, which is necessary particularly when blowing bottles with complex shapes.


Intelligent Heating System Prevents Rejects


The preform heating system consists of four modules with nine levels of separately regulated halogen heating lamps. The heating system applied is a novel solution of the German company Adphos, which allows increasing the heating effectiveness considerably. The furnaces are now 50% shorter comparing with standard solutions. Additionally, the temperature distribution inside the preform wall thickness is more uniform, which allows to produce the highest quality bottles. The preform temperature is controlled by means of pyrometers immediately before the mould. The pyrometer data are transmitted to the PLC which controls the temperature regulation. This allows controlling properly the technological process repeatability. No rejects caused by fluctuations of temperature are produced.


Material Handling For Continuous Production


The bottle receiving system is adjusted to the connection of a pneumatic bottle conveyor. If the bottle could not be blown by the machine (e.g. too low preform temperature is set by the operator) then preforms are automatically thrown to a separate container.


A preform feeding and positioning system is delivered with the machine. Preforms are precisely positioned on carriages (the preform and then bottle transporting elements) by means of a worm system. Change of the preform thread, e.g. from BPF to PCO, requires only that one insert in the preform transporting carriage be changed. The insert fastening system allows changing it quickly and the machine downtime is very short.

Failure Prevention and Service

Syntec 6000 has an advanced failure diagnostics system. When the machine stops, the computer system gives clear indication of the cause of the error. That makes elimination of problems in the machine operation very easy. Additionally, it is possible to display the diagram of gauges together with their working elements, which allows locating the failure intuitively.  


A great advantage of the machine is very low operating cost. Syntec is designed to reduce as much as possible the necessity of replacing the wear and tear parts (e.g. by using the highest quality Merkel type sealings). The necessary maintenance service time is 20 minutes per month + renewal of the stretching rod sealings every 5 million bottles produced.


In case something should still go wrong, Gammagroup offers supreme technical service with advice by phone or with technicians on-site.
