Components for a profitable and energy-saving production
State-of-the-art FIFO injection units in all DESMA injection moulding machines. When the First-in-First-Out (FIFO) principle is applied, the material that has been plasticized first is injected into the mould. This results in an even dwell time of the compound in the injection unit at a constant stock pressure. During the entire plastification process, the stock temperature may be increased, thus considerably reducing costintensive cure time. In addition, the DESMA FIFO injection units permit an easy change of the compound because the optimally designed rinsing effect prevents the contamination with old rubber.
DESMA injection units at a glance
Exploiting cost-cutting potentials
The patented FIFO-A system is one of the most successful DESMA injection units. The injection unit is designed for average to very large injection volumes and offers an ideal operating comfort combined with a high stability of the injection moulding machine. The standard design includes the nozzle that can belifted off hydraulically.
Injection unit FIFO B
The FIFO-B system is in particular used on DESMA horizontal machines. The injection unit is basicallysuited for all injection moulding machines with lateral injection into the mould parting surface (T-series). The hydraulic nozzle lift-off permits a minimum through hole in the clamping unit - and thus a maximum deflection stability even in the middle section of the mould.
Injection unit FIFO C
The FIFO-C injection unit is ideally suited for smallest to average injection volumes. The tight-fitting nozzle provides for a short nozzle path in the injection unit. FIFO-C is the standard injection unit for C-frame injection moulding machines and small DESMA horizontal machines.
Need-based size range. DESMA injection units in different sizes are available for TPE applications. These systems can be used on all DESMA injection moulding machines, e.g. also on the D 957.050 HydroBalance with the innovative two-platen clamping system. For processing LSR and HTV, DESMA offers all FIFO-injection units also with the options for liquid and solid silicone.
