Alpha & Sigma Machines

ALPHA & SIGMA MACHINE SERIES

Perfect conditions for large-scale production of elastomer injection molded articles. The ALPHA and SIGMA series vertical machines represent our globally popular 968 and COMPACT series.

ALPHA AND SIGMA SERIES

500 kN to 6,300 kN clamping force ALPHA and SIGMA series vertical machines represent our globally popular 968 and COMPACT series. The perfect solution for a wide range of applications, such as rubber-to-metal bonding in the automotive and railroad sectors. The SIGMA SE series is particularly popular for the production of silicone composite insulators.

  • FIFO-technology for uniform residence time of the compound in the injection unit at constant melt pressure
  • Power-efficient hydraulic system with proportional flow rate
  • Optional CE certification available

SIGMA SE SERIES

Specially developed with extended heating platens for step injection molding of composite insulators and surge arresters.
The moving platen is specially reinforced to minimize deflection.

Machine sizes of 2,700 kN with 1,000 mm long platen, 4,500 kN with 1,500 mm long platen and 6,300 kN with 1,700 mm long platens are available.


SIGMA F AND SIGMA FA SERIES

The machines are specially designed for a compact footprint.
The 1,000 kN, 1,600 kN and 2,500 kN sizes are offered with various front-operated demolding devices.

  • FIFO-technology for uniform residence time of the compound in the injection unit at constant melt pressure
  • Simple, front-side operation
  • Compact, space-saving design
  • FIFO-injection technology

S SERIES

  • Energy-saving servo hydraulics
  • Significant noise level reduction
  • Improved positioning accuracy of all hydraulic movements
  • Control by DRC 1030

This flexible horizontal injection molding machine features a continuous hydraulic clamping system. All ALPHA H machines have the same construction and design criteria as our European machine series and are equipped with appropriate hydraulic and thermal oil control units. ALPHA machines are available with different control systems. These have useful functions for professional process control and process optimization. CE certification is available as an option.

All ALPHA machines are equipped with our proven FIFO-B injection units in sizes from 250 cc to 4,000 cc.
Contact your regional sales manager for more details.

  • Optionally available with FIFO-B or FIFO-C injection unit
  • Various automation systems possible
  • DesFlex compensation system for low or zero rework production of precision parts
  • Ergonomic design
  • Fully automated operation of the system possible

FIFO-Advanced

The FIFO-Advanced injection unit offers further advantages. In addition to further improved injection accuracy, the very stable overall design allows significantly larger silicone stopper systems to be combined. This drastically reduces refill cycles.

The FIFO-B injection unit with integrated hydraulic nozzle lift is used in particular for DESMA horizontal machines. In principle, this injection unit is also optimally suited for injection molding machines with lateral injection into the mold parting line (T series).

The FIFO-C injection unit is ideal for the smallest to medium injection volumes. Due to the fixed nozzle, a very short nozzle length is given. Our FIFO-C is the standard injection unit for C-frame injection molding machines and small DESMA horizontal machines.
