   Injection Units  




First In First Out (FIFO)


All DESMA machines are equipped with injection units operating on the First-In-First-Out-principle. This means: The material which was plasticised first is also the first to be injected. This involves a constant residence time of the compound in the injection unit at a constant mass pressure. During the whole plasticising process it is possible to set the mass temperature higher. This results in distinctly reduced cure times.

This results in distinctly reduced cure times.

 
FIFO A

Our most successful injection unit, the patented FIFO A, is perfectly suited for medium to extremely large injection volumes and delivers an unequalled operating convenience with maximum machine stability.  A retractable nozzle is standard.

 
FIFO C

Our injection unit FIFO C is dimensioned for smallest to medium injection volumes. Thanks to its fixed position, the nozzle length is very short. This system FIFO C is the standard injection unit for C-frame machines.

Advantages : 

Uniform rheology of plasticised compound.

Higher stock temperatures reduce the cure time.

Rubber strip intake can be reached without scaffold and ladder up to the biggest machine with 10000kN.

Influenced of weight of the Injection unit on back pressure is only 10% compared to conventional systems.

Short flow path in injection piston, low back pressure 

Retractable nozzle thought hydraulic cylinder.

The same back pressure in the rubber material during the whole feed stroke

Constant screw length during plasticising phase

Extruding into the air with piston retracted.

Easy and fast compound changes and cleaning.

Easily adoptable devices for processing paste and liquid silicone rubber.
