VERTICAL MACHINES
VERTICAL MACHINES OFFER FLEXIBILITY AND FOOTPRINT ADVANTAGES
DESMA vertical machines (deemed 968 series) uses a clamping system that opens and closes vertically. DESMA offers two basic options; a closing from the top with lateral or side injection (what we call our 968 T series machines) and a closing from the bottom with injection through the upper bolster (what we call our 968 ZO series). There are attributes for each type and the molding process including tool design typically drives the decision for ZO or T.
Top injection (ZO) is most common in the market due to the flexibility and footprint of the machine. Top inject machines have a movable lower bolster that opens and closes every cycle. The upper bolster or fixed bolster does not move. Top inject machines, depending on size of the machine may require a platform or pit, unless the DESMA patented BENCHMARK clamping system is selected. The BENCHMARK clamp uses high speed machine tool technology to slide the high pressure hydraulic cylinder in and out from under the bolster, allowing for a very low resting position for demolding.
Side inject machines (T series) inject rubber laterally into a clamping station that has a fixed lower bolster but a movable upper bolster. T series machines typically require the injection unit to disengage from the mold or cold runner package prior to opening. A typical application of DESMA 968 T machines are stack mold designs with a center mounted cold runner (CRB) for the production of thin engine gaskets. T machines also offer a short distance for the unvulcanized rubber to travel due to the orientation of the injection unit. T machines have increased options for very large shot volumes compared to injection units that reside on top of a press (ZO).
SERVOGEAR

FLEXINTERLOCK
Setting freely programmable core pull locks yourself is made uncomplicated by FlexInterlock.
Set core pull interlocks yourself
- FIFO-A
- FIFO-ADVANCED
- FIFO-B
- FIFO-C
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.
QUICKLOCK
The hydro-mechanical quick clamping system QuickLock also makes ‚hot‘ mold changes possible within a few minutes. In combination with DESMA preheating units, set-up times can thus be significantly minimized and the productivity of the injection molding machines increased.
Shorten set up times
